RFC4259 - A Framework for Transmission of IP Datagrams over MPEG-2 Networks

This document describes an architecture for the transport of IP Datagrams over ISO MPEG-2 Transport Streams (TS). The MPEG-2 TS has been widely accepted not only for providing digital TV services but also as a subnetwork technology for building IP networks. Examples of systems using MPEG-2 include the Digital Video Broadcast (DVB) and Advanced Television Systems Committee (ATSC) Standards for Digital Television.

The document identifies the need for a set of Internet standards defining the interface between the MPEG-2 Transport Stream and an IP subnetwork. It suggests a new encapsulation method for IP datagrams and proposes protocols to perform IPv6/IPv4 address resolution, to associate IP packets with the properties of the Logical Channels provided by an MPEG-2 TS. This memo provides information for the Internet community.

RFC4326 - Unidirectional Lightweight Encapsulation (ULE) for Transmission of IP Datagrams over an MPEG-2 Transport Stream (TS)

The MPEG-2 Transport Stream (TS) has been widely accepted not only for providing digital TV services, but also as a subnetwork technology for building IP networks.

This document describes a Unidirectional Lightweight Encapsulation (ULE) mechanism for the transport of IPv4 and IPv6 Datagrams and other network protocol packets directly over the ISO MPEG-2 Transport Stream as TS Private Data. ULE specifies a base encapsulation format and supports an extension format that allows it to carry additional header information to assist in network/Receiver processing. [STANDARDS-TRACK]

RFC4947 - Address Resolution Mechanisms for IP Datagrams over MPEG-2 Networks

This document describes the process of binding/associating IPv4/IPv6 addresses with MPEG-2 Transport Streams (TS). This procedure is known as Address Resolution (AR) or Neighbor Discovery (ND). Such address resolution complements the higher-layer resource discovery tools that are used to advertise IP sessions.

In MPEG-2 Networks, an IP address must be associated with a Packet ID (PID) value and a specific Transmission Multiplex. This document reviews current methods appropriate to a range of technologies (such as DVB (Digital Video Broadcasting), ATSC (Advanced Television Systems Committee), DOCSIS (Data-Over-Cable Service Interface Specifications), and variants). It also describes the interaction with well-known protocols for address management including DHCP, ARP, and the ND protocol. This memo provides information for the Internet community.

RFC5163 - Extension Formats for Unidirectional Lightweight Encapsulation (ULE) and the Generic Stream Encapsulation (GSE)

This document describes a set of Extension Headers for the Unidirectional Lightweight Encapsulation (ULE), RFC 4326.

The Extension Header formats specified in this document define extensions appropriate to both ULE and the Generic Stream Encapsulation (GSE) for the second-generation framing structure defined by the Digital Video Broadcasting (DVB) family of specifications. [STANDARDS-TRACK]

RFC5458 - Security Requirements for the Unidirectional Lightweight Encapsulation (ULE) Protocol

The MPEG-2 standard defined by ISO 13818-1 supports a range of transmission methods for a variety of services. This document provides a threat analysis and derives the security requirements when using the Transport Stream, TS, to support an Internet network-layer using Unidirectional Lightweight Encapsulation (ULE) defined in RFC 4326. The document also provides the motivation for link-layer security for a ULE Stream. A ULE Stream may be used to send IPv4 packets, IPv6 packets, and other Protocol Data Units (PDUs) to an arbitrarily large number of Receivers supporting unicast and/or multicast transmission.

The analysis also describes applicability to the Generic Stream Encapsulation (GSE) defined by the Digital Video Broadcasting (DVB) Project. This memo provides information for the Internet community.
