Mbone (short for " multicast backbone") was an experimental backbone and virtual network built on top of the Internet for carrying IP multicast traffic on the Internet . It was developed in the early 1990s and required specialized hardware and software. Since the operators of most Internet routers have disabled IP multicast due to concerns regarding bandwidth tracking and billing, the Mbone was created to connect multicast-capable networks over the existing Internet infrastructure.
14-766: Mbone was created by Van Jacobson , Steve Deering and Stephen Casner in 1992 based on a suggestion by Allison Mankin . During March 16–20, 1992 the first significant use of the MBONE took place from the Internet Engineering Task Force (IETF) meeting in San Diego with 20 sites listening. On May 23, 1993, Wax or the Discovery of Television Among the Bees was streamed over the Mbone, becoming "the first movie to be transmitted on
28-740: A B.S. in mathematics from the University of Arizona. He did graduate work at Lawrence Berkeley Laboratory. His work redesigning TCP/IP 's congestion control algorithms ( Jacobson's algorithm ) to better handle congestion is said to have saved the Internet from collapsing in the late 1980s and early 1990s. He is also known for the TCP/IP Header Compression protocol described in RFC 1144: Compressing TCP/IP Headers for Low-Speed Serial Links , popularly known as Van Jacobson TCP/IP Header Compression . He
42-555: Is an American computer scientist , renowned for his work on TCP/IP network performance and scaling. He is one of the primary contributors to the TCP/IP protocol stack—the technological foundation of today’s Internet. Since 2013, Jacobson is an adjunct professor at the University of California, Los Angeles (UCLA) working on Named Data Networking . Jacobson studied Modern Poetry, Physics, and Mathematics and received an M.S. in physics and
56-623: Is the co-author of several widely used network diagnostic tools, including traceroute , tcpdump , and pathchar. He was a leader in the development of the multicast backbone (MBone) and the multimedia tools vic, vat, and wb. Jacobson worked at the Lawrence Berkeley Laboratory from 1974 to 1998 as a Research scientist in the Real-time Controls Group and later group leader for the Network Research Group. He

84-413: 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. Van Jacobson Van Jacobson
98-501: The Internet." On June 24, 1993, the band Severe Tire Damage was the first to perform live on the Mbone. On November 11, 1993 Sky Cries Mary performed on the Mbone from Bellevue, WA sponsored by Starwave. On August 23, 1994, the band Deth Specula broadcast the first live concert over the Mbone. A November 1994 Rolling Stones concert at the Cotton Bowl in Dallas with 50,000 fans

For his work, Jacobson received the 2001 ACM SIGCOMM Award for Lifetime Achievement "for contributions to protocol architecture and congestion control", the 2002 IEEE Koji Kobayashi Computers and Communications Award , and was elected to the National Academy of Engineering in 2004 for his "contributions to network protocols, including multicasting and
126-499: 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. 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

Van Jacobson is now working with the NDN Consortium funded by the National Science Foundation to explore and create the future of the internet. Van Jacobson together with his colleague at LBL, Steven McCanne, won R&D Magazine's 1995 R&D 100 Award for development of a software toolpack that enables multiparty audio and visual conferencing via

Mbone was predominantly used by research and scientific entities, including NASA. 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

He joined PARC as a research fellow in August 2006. In January 2006 at Linux.conf.au , Jacobson presented another idea about network performance improvement, which has since been referred to as network channels . Jacobson discussed his ideas on Named data networking (NDN),

Mick Jagger opened the concert by saying, "I wanna say a special welcome to everyone that's, uh, climbed into the Internet tonight and, uh, has got into the M-bone. And I hope it doesn't all collapse." A year later the Mbone was used, this time symmetrically (simultaneous transmission and reception without hierarchy among participants), for a first experience of real-time graphical interaction without
