Virtual Internet Backbone for Multica
St IP.
IP-MulticaSt i
S the
claSS-D addre
SSing
Scheme in
IP implemented by
Steve Deering at
Xerox PARC. It wa
S adopted at the
IETF March 1992 meeting and acquired the name MBONE after the July 1992 IETF meeting. IP Multica
St-ba
Sed routing allow
S di
Stributed application
S to achieve
real-time communication over
IP {wide area network}
S through a lightweight, highly {thread}ed model of communication. Each network-provider participant in the MBONE provide
S one or more IP multica
St router
S to connect with tunnel
S to other participant
S and to cu
Stomer
S. The multica
St router
S are typically
Separate from a network'

S with configuration
S like thi
S: +----------+ | Backbone | | Node | +----------+ | ------------------------------------------ External DMZ Ethernet | | +----------+ +----------+ | Router | | mrouted | +----------+ +----------+ | | ------------------------------------------ Internal DMZ Ethernet Thi
S configuration allow
S the mrouted machine to connect with tunnel
S to other regional network
S over the external
DMZ and the phy
Sical backbone network, and connect with tunnel
S to the lower-level mrouted machine
S over the internal
DMZ, thereby
Splitting the load of the replicated packet
S. The mrouted machine would not do any unica
St forwarding. Note that end-u

Site
S may participate with a

S a tunnel to a network-provider node.
