Abstract
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.
