After one year of extensive work and discussions, both "Quality of Service" and "Management and Control Harmonization" Working Groups have proposed new recommendations. With the incorporation of the new recommendations into the next phase of the SatLabs certification programme, DVB-RCS certified terminals will be able to interoperate in different systems requiring only changes to their configuration and be able to provide real-time services efficiently.

In line with the latest revision of the DVB-RCS standard (v1.4.1), these recommendations detail how the following enhanced features operate in a DVB-RCS system:
  • Harmonized support for IP Classes of Service according to the IETF DiffServ recommendations, and their mapping on DVB-RCS specific MAC layer Capacity Categories and Dynamic Requests,
  • Standardized management procedures based on the IETF SNMP recommendations,
  • A Common SNMP Management Information Base (MIB) for all DVB-RCS terminals,
  • Standardized procedures and protocols for terminal's Configuration file and log files management,
  • A Common protocol for terminal's software updates based on Multicast distribution.
The SatLabs System Recommendations document is currently being updated by the SatLabs Group in order to incorporate those new features. This document complements the DVB-RCS standard and associated guidelines in order to support interoperability between different terminals. In parallel work on the Common Test Bed upgrade and the revision of the Outline Test Plan is well under way.

Before the end of this year, a new phase of SatLabs certification will be able to start. It will incorporate, not only those new mandatory features regarding QoS and Management, but also very important options like iPEP (which was specified in 2005) and DVB-S2. The value of the SatLabs Mark and its associated benefits in terms of multi-vendor interoperability, cost of operation and performance will then be greater than ever.
