1. Introduction

The SatLabs Group [SATLABS] is an international non-profit EEIG (European Economic Interest Grouping) committed to large-scale adoption and deployment of the Digital Video Broadcasting Return Channel via Satellite (DVB-RCS) standard [ETSI-RCS]. SatLabs members are service providers, satellite operators, system integrators, terminal manufacturers, and technology providers with an interest in DVB-RCS.

Since its creation in 2001, the main goal of the SatLabs Group has been to achieve interoperability between DVB-RCS terminals and systems. Therefore, the Group has defined the SatLabs Qualification Program, which provides an independent certification process for DVB- RCS terminals based on System Recommendations defined by SatLabs. To enhance product interoperability, beyond the physical-layer and MAC- layer mechanisms defined in the DVB-RCS standard, SatLabs has expanded its Recommendations in the field of DVB-RCS terminal management [SATLABS]. As part of this effort, SatLabs has specified a common Simple Network Management Protocol (SNMP) Management Information Base (MIB) for DVB-RCS terminals, which is defined in this document.

A DVB-RCS terminal is denoted as a Return Channel Satellite Terminal (RCST) in the remainder of this document. This consists of an Indoor Unit (IDU) and an Outdoor Unit (ODU) connected through an Inter- Facility Link (IFL), usually a coaxial L-band interface. On the user side, the IDU is connected to the user network through a Local Area Network (LAN) interface (usually Ethernet). On the network side, the ODU is connected via a satellite link (the air interface).

The SatLabs Group DVB-RCS MIB is implemented in the IDU of an RCST. RCST management can be performed either through the LAN interface (local management) or through the air interface (remote management from the Network Control Center, NCC). RCST and NCC elements are shown on Figure 1.

2.2. Glossary

The terms in this document are derived either from DVB-RCS standard specifications [ETSI-RCS] or from SatLabs System Recommendations [SATLABS].

2.2.1. Star DVB-RCS Network

This denotes a hub-and-spoke configuration where all communications pass through a central hub, which usually also includes the NCC. Peer-to-peer communication between RCSTs is possible through a double satellite hop (this traffic has to pass through the hub).

2.2.2. Mesh DVB-RCS Network

This denotes a mesh configuration that supports peer-to-peer communications in a single satellite hop directly between RCSTs.

2.2.3. Transparent DVB-RCS Network

This denotes a network using transparent satellite transponders. Star or mesh network configurations can be supported. In the case of a mesh configuration, RCSTs need to incorporate a TDMA receiver in addition to the TDM receiver.

2.2.4. Regenerative DVB-RCS Network

This denotes a network that uses regenerative satellite transponders, i.e. includes some On-Board Processing functionality, which allows demodulation and decoding of the uplink TDMA signals and re-multiplex of the traffic into TDM signals on the downlink. Star or mesh network configurations can be supported.

2.2.5. DVB-RCS MAC Layer

The DVB-RCS MAC layer represents the air interface of an RCST, as specified in [ETSI-RCS]. The interface is bi-directional and supports IP traffic over hub-spoke (star) and mesh satellite network topologies.

2.2.6. DVB-RCS TDM

The DVB-RCS TDM corresponds to the forward link of a DVB-RCS transparent system or the downlink of a DVB-RCS regenerative system. It is based on either the DVB-S or DVB-S2 standard, specified in [ETSI-DVBS] and [ETSI-DVBS2] respectively. In the DVB-RCS context, this interface is uni- or bi-directional, as it may also be used for a return channel dedicated to a single terminal.

2.2.7. DVB-RCS TDMA

The DVB-RCS TDMA corresponds to the return or mesh link of an RCS transparent system or the uplink of an RCS regenerative system. It is specified in [ETSI-RCS].

In the context of star transparent and mesh regenerative DVB-RCS systems, this interface is uni-directional.

In the context of mesh transparent DVB-RCS systems, this interface is bi-directional.

2.2.8. IDU

This is the indoor part of the RCST (including at least the power supply, and usually also the modem and networking functions).

2.2.9. ODU

This is the outdoor part of the RCST (including at least the aerial, and usually also the LNB and BUC).

2.2.10. RCST

This is the Satellite Terminal, installed on the customer premises. It is composed of the IDU and ODU.

2.2.11. NCC

The NCC provides Control and Monitoring Functions. It generates control and timing signals for the operation of the DVB-RCS Network.

2.2.12. Configuration File

The configuration file is an XML-formatted file, storing configuration parameters for the RCST and their values.

2.2.13. Log File

The log file is stored at the RCST. This is used to log particular events that occur on the RCST side.

2.2.14. Installation Log File

The installation log file is stored at the RCST. This logs particular events that occur on the RCST side and are related to RCST installation phase.

2.2.15. Antenna Alignment

This is the process to align the RCST antenna, part of the ODU, in order to enable bi-directional communication (uplink, downlink) with the satellite network.

2.2.16. CW Frequency

The CW frequency is the frequency of a Continuous Wave signal. It is a narrowband carrier transmitted for the duration of measurements during the installation of an RCST.

2.2.17. Request Class

A Request Class (RC) is a representation of a Per-Hop Behavior (PHB) at the MAC layer. It defines a behavior of the MAC layer for a given aggregation of traffic. This behavior includes a combination of Capacity Categories associated to the RC and a priority with respect to the other RCs supported by an RCST.

2.2.18. Channel ID

Each Request Class is identified by a unique Channel_ID in the communication between the RCST and the NCC.

2.2.19. ATM Profile

The ATM profile is one of the two profiles for traffic burst format on a DVB-RCS TDMA. It is based on one or more concatenated ATM cells, each of length 53 bytes, plus an optional prefix.

2.2.20. MPEG Profile

The MPEG profile is one of the two profiles for traffic burst format on the DVB-RCS TDMA. It is based on a number of concatenated MPEG2-TS packets, each of length 188 bytes.

2.2.21. PID Pool

For the MPEG profile, several RCs may be mapped within a pool of several PIDs to allow cross-RC Section Packing [ETSI-DAT]. Section Packing can be used on all PIDs and higher priority traffic can always preempt lower priority streams. This reduces the need for padding.

2.2.22. Capacity Categories

The TDMA timeslot allocation process for the DVB-RCS uplink supports several Capacity Categories.

The Capacity Categories CRA, RBDC, and A/VBDC, when authorized for an RC, have to be configured from the NCC. Their configuration parameters are used to inform the RCST of the configuration of each category at the NCC side and thus help in Capacity Requests computation.

The categories are treated independently for each RC. A SatLabs optional feature is defined that allows their configuration at the RCST level in addition to configuration per RC. This feature is denoted RCST_PARA.

2.2.22.1. Continuous Rate Assignment (CRA)

CRA is a rate capacity that is provided in full in a continuous manner to the RCST while required.

2.2.22.2. Rate-Based Dynamic Capacity (RBDC)

RBDC is a rate capacity that is requested dynamically by an RCST. RBDC is provided in response to explicit requests from the RCST to the NCC, such requests being absolute (i.e., corresponding to the full rate currently being requested). Each request overrides all previous RBDC requests from the same RCST and is subject to a maximum rate limit.

2.2.22.3. Volume-Based Dynamic Capacity (VBDC)

VBDC is a volume capacity that is requested dynamically by an RCST. VBDC is provided in response to explicit requests from the RCST to the NCC, such requests being cumulative (i.e., each request adds to all previous requests from the same RCST).

2.2.22.4. Absolute Volume-Based Dynamic Capacity (AVBDC)

AVBDC is a volume capacity that is requested dynamically by an RCST. This capacity is provided in response to explicit requests from the RCST to the NCC, such requests being absolute (i.e., this request replaces the previous ones from the same RCST).

The combination of AVBDC and VBDC is seen as a single Capacity Category, denoted A/VBDC.

2.2.22.5. Population ID

This defines a group of RCSTs within a network.

2.2.23. Start Transponder

This is the satellite transponder on which the communication is initiated from an RCST point of view when in the installation mode. The parameters corresponding to this transponder (satellite orbital position, frequency, etc.) are stored at the RCST as power-up configuration data.

2.2.24. DVB-S

DVB-S is the Digital Video Broadcast over Satellite [ETSI-DVBS]. It is a framework and set of associated standards published by ETSI for the transmission of video, audio, and data, using the ISO MPEG-2 standard [ISO-MPEG], over satellite links.

2.2.25. DVB-S2 and CCM/VCM/ACM

DVB-S2 is the Second Generation of the Digital Video Broadcast for Satellite applications standard [ETSI-DVBS2]. It is a framework and set of associated standards published by ETSI for the transmission of video, audio, and data.

BBFRAME:

The main framing unit of the DVB-S2 protocol stack.

CCM:

In CCM transmission mode, the forward link uses a constant set of transmission parameters (FEC coding rate and modulation scheme) for all receivers.

VCM:

In VCM transmission mode, the forward link uses transmission parameters that are variable on a BBFRAME-by-BBFRAME but fixed on a Receiver basis, according to fixed link and propagation conditions for each Receiver.

ACM:

In ACM transmission mode, the forward link uses transmission parameters that are dynamically adjusted on a BBFRAME-by-BBFRAME and Receiver-per-Receiver basis, according to actual link and propagation conditions. In order to implement ACM, feedback from each Receiver has to be provided by DVB-RCS return channel.

2.2.26. Interactive Network

This is another name for a DVB-RCS-based satellite network.

3. MIB Module Overview

This MIB module provides a set of objects required for the management of a SatLabs-compliant RCST. The specification is derived from the parameters and protocols described in [SATLABS].

The MIB module in this document uses the following OBJECT IDENTIFIER values, as already assigned by IANA under the smi-numbers registry [IANA]:

         +------------+---------------------------+
         | Descriptor | OBJECT IDENTIFIER value   |
         +------------+---------------------------+
         |dvbRcsMib   |{ mib-2 transmission 239 } |
         +------------+---------------------------+

Table 1: Object Identifiers for the MIB

These values have been assigned for this MIB under the 'mib-2.transmission' subtree.

3.1. Textual Conventions

This MIB module defines new textual conventions for RCST indications of SatLabs-defined capabilities, including profiles, options, and optional features.

DvbRcsSystemSatLabsProfileMap represents the SatLabs profiles supported as defined in [SATLABS].

DvbRcsSystemSatLabsOptionMap represents the SatLabs options supported as defined in [SATLABS]. These are options that are used for the certification of SatLabs terminals. They represent important functionality, with impact on interoperability, and their support is advertised with the RCST certification level.

DvbRcsSystemSatLabsFeatureMap represents the SatLabs optional features supported as defined in [SATLABS]. These represent minor features, not necessary for interoperability. They are not used for the certification of SatLabs terminals.

3.2. Structure of the MIB

This MIB module is structured into two top-level groups:

  • The dvbRcsMibObjects group includes all the managed objects of the DVB-RCS MIB.
  • The dvbRcsConformance group includes the compliance statements for DVB-RCS terminals that are compliant with [SATLABS]. The managed objects are grouped into formal object groups (i.e., units of conformance) according to their relation to specific SatLabs options or features. The conformance statements (MODULE- COMPLIANCE specification) are described within the dvbRcsRcstCompliances group, while the units of conformance are described within the dvbRcsRcstGroups group.

The dvbRcsMibObjects group is further structured into three groups: dvbRcsRcst, dvbRcsFwdLink, and dvbRcsRtnLink.

The dvbRcsRcst group covers management related to the RCST equipment. It is structured into six groups:

  • dvbRcsRcstSystem
  • dvbRcsRcstNetwork
  • dvbRcsRcstInstall
  • dvbRcsRcstQos
  • dvbRcsRcstControl
  • dvbRcsRcstState

The dvbRcsFwdLink group covers management information related to the RCST forward link. It is structured into two groups:

  • dvbRcsFwdConfig
  • dvbRcsFwdStatus

The dvbRcsRtnLink group covers management information related to the RCST return link. It is structured into two groups:

  • dvbRcsRtnConfig
  • dvbRcsRtnStatus

Tables within each of these groups cover different functions like return link traffic management (packet classes, Request Classes, PID pools) and forward link configuration and status.

Rows created automatically (e.g., by the device according to the hardware configuration) may, and generally will, have a mixture of configuration and status objects within them. Rows that are meant to be created by the management station are generally restricted to configuration (read-create) objects.

3.3. Relationship to the Interfaces MIB Module

This section clarifies the relationship of this MIB module to the Interfaces MIB [RFC2863]. Several areas of correlation are addressed in the following. The implementer is referred to the Interfaces MIB document in order to understand the general intent of these areas.

IANA has assigned three ifType labels for DVB-RCS. Each RCST MUST support at least the three following interfaces:

   o  dvbRcsMacLayer (239), -- DVB-RCS MAC Layer

DVB-RCS MAC Layer represents the complete air interface of an RCST, as specified in [ETSI-RCS]. This interface supports star and mesh networks and is bi-directional. Only star networks are considered by the present MIB module.

   o  dvbTdm (240), -- DVB Satellite TDM

DVB-RCS physical link based on Time-Division Multiplexing. It corresponds to the forward link of an RCS transparent system or the downlink of an RCS regenerative system. It is based on either the DVB-S or DVB-S2 standard, specified in [ETSI-DVBS] and [ETSI-DVBS2] respectively. Only transparent systems are considered by the present MIB module.

In the DVB-RCS context, this interface is uni- or bi-directional.

In the present MIB module, only a uni-directional (i.e., forward link, or downstream) dvbTdm interface is considered.

   o  dvbRcsTdma (241), -- DVB-RCS TDMA

DVB-RCS physical link based on Time-Division Multiple Access. It corresponds to the return or mesh link of an RCS transparent system or the uplink of an RCS regenerative system. It is based on the DVB-RCS standard specified in [ETSI-RCS].

In the context of star transparent and mesh regenerative DVB-RCS systems, this interface is uni-directional.

In the context of mesh transparent DVB-RCS systems, this interface is bi-directional.

Only star transparent systems are considered by the present MIB module (i.e., return link, or upstream).

The protocol stack (as reflected in ifStackTable) will be as follows:

           +--------------------------+
           |            IP            |
           +--------------------------+
           |      dvbRcsMacLayer      |
           +---------------+----------+
           |  dvbRcsTdma   | dvbTdm   |
           +---------------+----------+

Figure 2: RCST Protocol Stack

An additional Ethernet interface is used on the LAN side of the RCST (see Figure 1).

An instance of ifEntry exists for each dvbTdm interface, for each dvbRcsTdma (normally only one), and for each dvbRcsMac layer (normally only one).

The interface counters relate to:

  • dvbRcsMacLayer: DVB-RCS two-way MAC interface that counts aggregate Multi-Protocol Encapsulation (MPE) frames, Generic Stream Encapsulation (GSE) encapsulated PDUs (equals IP packets), and ATM Adaptation Layer 5 (AAL5) frames.

MPE is specified in [ETSI-DAT] and is transported over MPEG, which is specified in [ISO-MPEG]. MPEG is transported over GS or TS (Transport Stream) carriers. The TS carrier is specified in [ETSI-DVBS] for DVB-S and [ETSI-DVBS2] for DVB-S2.

GSE is specified in [ETSI-GSE] and is transported over the GS (Generic Stream) carrier, which is specified in [ETSI-DVBS2].

ATM is specified in [ITU-ATM].

AAL5 is specified in [ITU-AAL5].

  • dvbTdm: The DVB-RCS TDM interface that counts MPEG TS packets at stream level, if the TS format is used. If the Generic Stream (GS) format is used, it counts GSE packets.
  • dvbRcsTdma: The DVB-RCS TDMA interface that counts aggregate ATM and MPEG TS packets.

The ifStackTable [RFC2863] MUST be implemented to identify the relationships among sub-interfaces.

The following example is a DVB-RCS star network with DVB-S and DVB- RCS. As illustrated on Figure 3, it shows a DVB-RCS MAC interface with one downstream and one upstream interface. In this network, ATM encapsulation is used in the DVB-RCS uplink. Two ATM Logical Ports are shown. DVB-S2 or DVB-S can be used in the downlink.

ifType 214 'mpegTransport' can also be used for counting TS packets and bytes for sub-interfaces of dvbRcsTdma or dvbTdm, e.g., per PID- oriented or per TS-oriented, as desired and applicable.

Figure 3: Example Stacking

As can be seen from this example, the dvbRcsMacLayer interface is layered on top of the downstream and upstream interfaces, and the upstream interface is layered on top of upstream ATM logical links.

In this example, the assignment of index values could be as follows:

     ifIndex           ifType                     Description
    ----------------------------------------------------------------
        2        dvbRcsMacLayer (239)        DVB-RCS MAC Layer
        3        dvbRcsTdma (241)            DVB-RCS TDMA Upstream
        4        dvbTdm(240)                 DVB-RCS TDM Downstream
        5        atm-logical(80)             ATM Logical Port
        6        atm-logical(80)             ATM Logical Port

The corresponding ifStack entries would then be:

3.4. MIB Groups Description

3.4.1. dvbRcsRcstSystem

The MIB objects in this group gather some basic information that would allow anyone to trace the history -- the life -- of the RCST, as well as to get a complete description of its constitution on the component point of view, including the SatLabs options/features support statement. Many of the parameters will be defined at installation.

This group contains description parameters related to the RCST type (ODU type) and location. These parameters are believed to stay unchanged once it has been defined during installation. Modification of hardware equipment, maintenance operations, and geographical re- location may require an update of those MIB objects. Note that the dvbRcsRcstSystem.dvbRcsSystemLocation object gives the location of the ODU antenna, which is needed for network operation, while the system.sysLocation (MIB-II SNMP OID) provides the location of the IDU unit, which cannot be used for the same purpose.

The RCST must provide either Read-Write access to dvbRcsSystemOdu parameters or, alternatively, provide the list of supported devices through the dvbRcsRcstOduListGroup (see conformance section). This group of parameters, defined in the dvbRcsRcstSystem group, allows the selection by the RCST installer of the actual ODU type. In such a case, the installer must set dvbRcsOduTxType, dvbRcsOduRxType, and dvbRcsOduAntennaType according to the selected BUC, LNB, and antenna respectively.

3.4.2. dvbRcsRcstNetwork

This group contains all the MIB objects related to network parameters.

In this subgroup, two objects have been defined in order to differentiate between control and user traffic and associate them with a physical interface. Both dvbRcsRcstNetwork.dvbRcsNetworkLanIpAddress (Traffic) and dvbRcsRcstNetwork.dvbRcsNetworkOamInetAddress (OAM) provide the value of the IP address of, respectively, the user traffic and the control and management traffic.

3.4.3. dvbRcsRcstInstall

This group contains all the information related to the RCST installation and commissioning. Many parameters are believed to stay unchanged once it has been defined during installation. Modification of hardware equipment, maintenance operations, and geographical re- location may require an update of those MIB objects.

3.4.4. dvbRcsRcstQos

This group contains objects to configure the Quality of Service (QoS) of the RCST by the NCC.

The dvbRcsPktClass table defines the packet classification for IP layer 3 classifications. Each dvbRcsPktClass entry is mapped to a dvbRcsPhbEntry in the dvbRcsPhbMappingTable.

The dvbRcsPhbMappingTable makes the relation between a packet classification entry, a Per-Hop Behavior (PHB) identifier, and a Request Class entry.

The dvbRcsRequestClassTable defines all the layer 2 DVB-RCS QoS parameters.

3.4.5. dvbRcsRcstControl

This MIB group contains objects a network manager can use to invoke actions and tests supported by the RCST agent and to retrieve the action/test results.

3.4.6. dvbRcsRcstState

This MIB group describes the fault state, software versions, and configuration file versions of the RCST.

3.4.7. dvbRcsFwdLink (dvbRcsFwdConfig and dvbRcsFwdStatus groups)

This MIB group contains parameters that enable access to data about the forward link.

Configuration information is kept in the dvbRcsFwdLink.dvbRcsFwdConfig subgroup. Status information is kept into the dvbRcsFwdLink.dvbRcsFwdStatus subgroup.

The information in dvbRcsFwdLink.dvbRcsFwdConfig.dvbRcsFwdStartTable is used for the first time the RCST tries to acquire the forward link. All these object values are aligned with the Satellite Delivery System Descriptor in the Network Information Table (NIT) table [ETSI-SI].

The objects in the dvbRcsFwdLink.dvbRcsFwdConfig.dvbRcsFwdStatusTable are aligned with the satellite forward path descriptor from the RCS Map Table (RMT) [ETSI-RCS] and with the Physical Layer (PL) Header [ETSI-DVBS2], which specifies the MODCOD (modulation and FEC rate) and the Type (frame length short or long and the presence/absence of pilots).

3.4.8. dvbRcsRtnLink (dvbRcsRtnConfig and dvbRcsRtnStatus groups)

This MIB group contains parameters that enable access to data about the return link.

Configuration information is kept in the dvbRcsRtnLink.dvbRcsRtnConfig subgroup. Status information is kept into the dvbRcsRtnLink.dvbRcsRtnStatus subgroup.

The RCST is only able to deal with one return link at a time. Hence, there is no need to define a table to collect the different SNMP objects, as it is done for the forward.

5. Security Considerations

This MIB module relates to a system that allows end users to access a private network or public Internet access. As such, improper manipulation of the MIB objects represented by this MIB module may result in denial of service to a large number of end users.

There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read- create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability:

  • The use of the dvbRcsNetworkNccMgtInetAddress object to specify management stations is considered only limited protection and does not protect against attacks that spoof the management station's IP address. The use of stronger mechanisms, such as SNMPv3 security, should be considered, where possible.
  • The dvbRcsSystemOdu objects, dvbRcsCtrlCwEnable, dvbRcsRtnConfigMaxEirp, dvbRcsRtnConfigDefIfLevel objects, and dvbRcsRcstInstall sub-tree can, if improperly or maliciously used, lead to unwanted emissions or emission levels on the satellite uplink, thereby resulting in potential degradation of the RCS service or other services using the frequency band being used.
  • The RCST may have its configuration file changed by the actions of the management system using a combination of the following objects: dvbRcsNetworkInstallLogFileDownloadUrl, dvbRcsCtrlDownloadFileCommand, dvbRcsCtrlActivateConfigFileCommand, or dvbRcsCtrlRebootCommand. An improper configuration file download may result in substantial vulnerabilities and the loss of the ability of the management system to control the satellite terminal.
  • Setting dvbRcsNetworkLogFileUploadUrl to a wrong address may potentially impact debugging/troubleshooting efforts.
  • Setting objects in dvbRcsPktClassTable could cause significant changes to default traffic filtering on an RCST.

Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability:

  • The dvbRcsNetworkNccMgtInetAddress object may provide sufficient information for attackers to spoof management stations that have management access to the device.
  • The dvbRcsRcstCurrentSoftwareVersion object may provide hints as to the software vulnerabilities of the RCST.
  • The object dvbRcsNetworkOamInetAddress and the table dvbRcsPktClassTable may provide clues for attacking the RCST and other subscriber devices.

SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPsec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.

It is RECOMMENDED that implementers consider the security features provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).

Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module, is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.

6. IANA Considerations

The transmission and ifType numbers described in Section 3 have already been assigned under the smi-numbers registry.
