Description of Working Group:

  The WG will develop new protocols and architectures to enable better
  deployment of IP over MPEG-2 transport and provide easier interworking
  with IP networks. Specific properties of this subnetwork technology
  include link-layer support for unicast and multicast, large numbers of
  down-stream receivers, and efficiency of transmission.

  These properties resemble those in some other wireless networks. The
  specific focus of the group is on the use of MPEG-2 transport
  (examples include the Digital Video Broadcast (DVB) standards: DVB-RCS;
  DVB-S and DVB-T and related ATSC Specifications) in next generation
  networks and is not concerned with the development, replacement, or
  retention of existing protocols on the existing generation of networks.

  The WG will endeavour to reuse existing open standard technologies,
  giving guidance on usage in IP networks, whenever they are able to
  fulfill requirements. For instance, we acknowledge the existing
  Multiprotocol Encapsulation (MPE) [ATSC A/90;ETSI EN 301192] and that
  this will continue to be deployed in the future to develop new
  markets. Any alternative encapsulation would need to co-exist with MPE.

  Appropriate standards will be defined to support transmission of IPv4
  and IPv6 datagrams between IP networks connected using MPEG-2
  transport subnetworks. This includes options for encapsulation, dynamic
  unicast address resolution for IPv4/IPv6, and the mechanisms needed to
  map routed IP multicast traffic to the MPEG-2 transport subnetwork.
  The
  standards will be appropriate to both MPE and any alternative
  encapsulation method developed. The developed protocols may also be
  applicable to other multicast enabled subnetwork technologies
  supporting large numbers of directly connected systems.

  The current list of work items is:

  Specify the requirements and architecture for supporting IPv4/IPv6 via
  MPEG-2 transmission networks. Such requirements should consider the
  range of platforms currently (or anticipated to be) in use. This draft
  will be an Informational RFC.

  Define a standards-track RFC defining an efficient encapsulation
  method. The design will consider the need for MAC addresses, the
  potential need for synchronisation between streams, support for a wide
  range of IPv4/IPv6 and multicast traffic.

  Provide an Informational RFC describing a framework for unicast and
  multicast address resolution over MPEG-2 transmission networks. The
  document will describe options for the address resolution process,
  relating these to appropriate usage scenarios and suggesting
  appropriate protocol mechanisms for both the existing Multi-Protocol
  Encapsulation (MPE) and the efficient encapsulation (2). Consideration
  will be paid to existing standards, and the cases for IPv6 and IPv4
  will be described.

  Define standards-track RFC(s) to specify procedures for dynamic
  address resolution for IPv4/IPv6. This will describe the protocol and
  syntax of the information exchanged to bind unicast and multicast flows
  to the MPEG-2 TS Logical Channels.  This will include specific
  optimisations appropriate for networks reaching large numbers of
  down-stream systems.
