::callout[type=note] M-Bone ::

Mbone was used for shared communication such as video teleconferences or shared collaborative workspaces. It was not generally connected to commercial Internet service providers, but often to universities and research institutions. Some other projects and network testbeds, such as Internet2's Abilene Network, made Mbone obsolete.

A "virtual room video conferencing system" (VRVS) started operation in 1997 using the Mbone, and was in operation through 2008.

A revived mboned (mbone deployment) working group was chartered by the Internet Engineering Task Force in 2014, as a forum to coordinate and document multicast deployment challenges and best practices.

Details

The purpose of Mbone was to minimize the amount of data required for multipoint audio/video-conferencing.

Mbone was free and it used a network of routers that support IP multicast, and it enables access to real-time interactive multimedia on the Internet. Many older routers do not support IP multicast. To cope with this, tunnels must be set up on both ends: multicast packets are encapsulated in unicast packets and sent through a tunnel. Mbone uses a small subset of the class D IP address space (224.0.0.0–239.255.255.255) assigned for multicast traffic. Mbone uses 224.2.0.0 for multimedia conferencing.
