Problems solved by technology

[0005] However, there is a problem in the above multicast scheme: there is a problem of scalability in the configuration of the distribution table, which is mainly caused by the use of a set of forwarding authority flags to control the transmission of multicast data packets
The forwarding permission flag set guides the multicast data packet from the sending user host to all receiving

Embodiment Construction

[0026] Method of the present invention is described in detail as follows in conjunction with accompanying drawing and embodiment:

[0027] The IP network structure of an embodiment of the method of the present invention is as figure 1 shown. The network in this embodiment consists of seven hosts (H1-H7) and seven routers (R1-R7). In the network of this embodiment, it is assumed that a video conference multicast session S is carried out among four hosts (host H1, host H2, host H4, and host H5). The following content describes the process of implementing the method of the present invention in this IP network. These descriptions are only illustrative illustrations of the present invention, and should not be regarded as limiting the content of the present invention.

[0028] The network in this embodiment is a network using the IP protocol. At present, the IP protocol has two versions, IPv4 and IPv6. The multicast transmission method can be applied to both the IPv4 network and ...

Abstract

The present invention relates to multi- broadcast transmitting method in IP network which belongs to computer communication technology field. The method includes: first, a virtual distributing net is established in IP network for each multi- broadcast conversation, the virtual distributing net is made up of multi- broadcast conversational main station and route device with multi- broadcast function connected by virtual chain circuit, and is with the only virtual distributing net identification; then, transmitting main station transmits multi- broadcast data pack to all receiving main station adopting broadcast modus in the virtual distributing net. On one hand, the present invention has original excellence of multi- broadcast conveying method based on virtual distributing net, such as supporting network layer multi- broadcast dispose with step by step, supporting multi- broadcast data pack bidirectional conveying etc, on the other hand, simplifying virtual distributing net configuring, supporting large scale multi- broadcast application through broadcast mechanism, guarantying multi- broadcast data pack conveying rightly.

Description

technical field [0001] The invention belongs to the technical field of computer communication, in particular to a multicast (Multicast) transmission method in an IP network. Background technique [0002] Multicast is an efficient point-to-multipoint or multipoint-to-multipoint transmission method. At present, the main services provided in the IP network, such as information retrieval, e-mail, instant messaging, etc., are based on the unicast transmission (that is, point-to-point transmission) technology of establishing data packets. However, many emerging services, such as Internet TV (IPTV), large-scale network conferencing, and large-scale distributed simulation, involve the simultaneous interaction of a large number of computers. If unicast is still used, a large amount of network bandwidth resources will be wasted, and performance is difficult to guarantee. Multicasting provides an effective point-to-multipoint and multipoint-to-multipoint transmission mechanism, which ...
