Abstract

   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.
