The local Message Bus (Mbus) is a light-weight
message-oriented coordination protocol for group
communication between application components. The
Mbus 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 transport protocol mechanisms ware
defined in RFC 3259.
