Multicast Transport (mcast)

A multicast transport is a peer-to-peer transport that carries reliable multicast communication among endpoints on many host computers. Multicast transports are efficient for high fan-out communication across a LAN.

Multicast transports excel at one-to-many communications.

Multicast transports use a negative acknowledgment protocol for reliable message transfer.

Multicast transports can also support one-to-one communications. For example, servers can send one-to-one replies to individual clients (that is, requestors). For configuration details, see Configuring Multicast Inbox Communication.

Multicast transports can filter messages by subscriber interest.
