The Multicast Backbone is based on IP multicasting using class-D addresses. The mbone concept was adopted at the March 1992 IETF in San Diego, during which it was used to audiocast to 40 people throughout the world. At the following meeting, in Cambridge, the name mbone was adopted. Since then the audiocast has become full two-way audio/video conferencing using two video channels, four audio channels, and involving hundreds of remote users.

the Multicast Backbone - the part of the Internet capable of interactive video and audio between multiple simultaneous participants.

Multicast Backbone. A virtual network that has been in existence since early 1992. Originated from an effort to multicast audio and video from meetings of the IETF. Shares the same physical media as the Internet. MBONE today is used by several hundred researchers for developing protocols and applications for group communication. It is a co-operative, volunteer effort.

See Multicast Backbone.

The multicast network overlaid atop the global Internet.

MBONE stands for the Multicast Backbone on the Internet, launched in 1992. It carries audio and video conferences, plus shared whiteboards.

Multicast Backbone: A virtual network on top of the Internet which supports routing of IP multicast packets, intended for multimedia transmission. The MBone is an experimental framework for developing and refining multicast protocols and applications on the Internet.

Multicast / Multimedia Backbone A collection of Internet routers that support IP multi-casting. The MBONE is used as a "broadcast" channel on which various public and private audio and video programs are sent.

The MBONE (Multicast Backbone) is a virtual network layered on top of the physical Internet to support routing of IP Multicast packets. It has been in existence for about 5 years. See www.mbone.com for more information.

MBONE is short for Multicast Backbone. Useful for the shared communication needs of video conferencing, MBONE is a collection of Internet routers that enable IP multicasting. A broadcast channel is the result, and can send multiple audio and video programs, either publicly or privately. It's also referred to as multicasting.

MBONE stands for Multicast Backbone. MBONE is actually a network that is already in use by researchers. The technology embodied in MBONE provides breakthroughs in broadcast communication to multiple Internet hosts. MBONE technology is expected to significantly enhance the way the Internet is used to transmit audio and video. You can find a good list of technical materials related to MBONE at the MICE National Support Centre.

IPv4 Multicast backbone

Multicast backbone; Multicast IP addresses do not address one host but possibly many hosts. MBONE is an infrastructure over which such addresses can be routed.

Multicast Backbone. A live audio and video multicast virtual network that sits on top of portions of the Internet. The MBONE network is made up of specially configured routers that support IP multicast with an "mrouted" multicast routing daemon.

An acronym for Multicast BackbONE, an Internet service which gives public access desktop video communications. The quality is poor with only 3-5 frames per second instead of the 30 frames per second of commercial television. Its advantage is that it avoids all telecommunications costs normally associated with teleconferencing. An interesting innovation is the use of MBONE for audio communications and an electronic "whiteboard" where the computer screen becomes a shared workspace where two physically remote parties can draw on and edit shared documents in real-time.

Multicast backbone. An extension to the Internet designed to support two-way transmission of data between multiple sites.

An experimental network that enables live video to be sent over the Internet.

Multicast Backbone on the Internet, a popular network for real-time audio and video application. IP-Multicast is the class-D addressing scheme in IP. IP Multicast-based routing facilitates distributed applications to achieve time-critical "real-time" communications over wide area IP networks through lightweight, highly threaded model of communication. http://www.mbone.com/techinfo

The Multimedia Backbone. A virtual network over which sound and video transmissions can be multicast. Also known as the Multicast Internet. See multicasting.

Multicast Backbone. An interconnected set of subnetworks and routers that support the delivery of IP multicast traffic. The MBone is a virtual network that is layered on top of sections of the physical Internet.

An experiment to upgrade the Internet to handle live multimedia messages. With mbone, a single packet can have multiple destinations and isn't split up until the last possible moment. This means that it can pass through several routers before it needs to be divided to reach its final destinations. This leads to much more efficient transmission and also ensures that packets reach multiple destinations at roughly the same time.

multicast backbone. The multicast backbone of the Internet. MBONE is a virtual multicast network composed of multicast LANs and the point-to-point tunnels that interconnect them.

a virtual network that is layered on top of portions of the physical Internet to support routing of IP multicast packets because that function has not yet been integrated into many production routers. The network is composed of islands that can directly support IP multicast, such as multicast LANs like Ethernet, linked by virtual point-to-point links called “tunnels.” The tunnel endpoints are typically workstation-class machines having operating system support for IP multicast and running the “mrouted” multicast routing daemon.

Mbone (short for "multicast backbone") is an experimental backbone for IP Multicast traffic across the Internet. Since most Internet routers do not yet support IP Multicast, the Mbone has evolved to connect multicast-capable networks over the existing Internet infrastructure. It is anticipated that the Mbone will eventually become obsolete as more routers understand and forward IP Multicast traffic, which is a standard feature in IPv6.
