Requirements for Multicast Protocols

Status of this Memo

This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited.

Summary

Multicast protocols have been developed over the past several years to address issues of group communication. Experience has demonstrated that current protocols do not address all of the requirements of multicast applications. This memo discusses some of these unresolved issues, and provides a high-level design for a new multicast transport protocol, group address and membership authority, and modifications to existing routing protocols.

1. Introduction

Multicast protocols have been developed to support group communications. These protocols use a one-to-many paradigm for transmission, typically using class D Internet Protocol (IP) addresses to specify specific multicast groups. While designing network serv...
