Abstract
This memo describes how the IP multicast service being developed by
the IP over ATM working group may be used to support IP broadcast
transmission. The solution revolves around treating the broadcast
problem as a special case of multicast, where every host in the
subnet or cluster is a member of the group.
An understanding of the services provided by RFC 2022 is assumed.
1. Introduction.
The IETF's first step in solving the problems of running IP over
Asynchronous Transfer Mode (ATM) technology is described in RFC 1577
[1]. It provides for unicast communication between hosts and routers
within Logical IP Subnets (LISs), and proposes a centralized ATM ARP
Server which provides IP to ATM address resolution services to LIS
members.
Two classes of IP service were omitted - multicast and broadcast
transmissions. Multicasting allows a single transmit operation to
cause a packet to be received by multiple remote destinations.
