Mbus Specification Published as RFC 3259

The Mbus protocol specification has been published by the IETF as RFC 3259.

The local Message Bus (Mbus) is a light-weight message-oriented coordination protocol for group communication between application components. It provides automatic location of communication peers, subject based addressing, reliable message transfer and different types of communication schemes. The protocol is layered on top of IP multicast and is specified for IPv4 and IPv6. The IP multicast scope is limited to link-local multicast. The RFC specifies the Mbus protocol, but leaves application-specific features and uses of the protocol undefined.
