Problems solved by technology

[0006] The overall solution is proposed in the existing hierarchical and orderly address grouping network technology, however, for the point-to-multipoint tunnels in the current public telecom packet data network, all of them are realized by static manual configuration, which lacks dynamic The specific implementation method of tunnel control is labor-intensive, complex and error-prone

Embodiment Construction

[0039] The technical solution provided by the embodiment of the present invention is to determine the source node HSAPN address of the point-to-multipoint tunnel, the destination leaf node HSAPN address of the point-to-multipoint tunnel, resource requirements, And intermediate nodes and other information, and send these information to the source node of the point-to-multipoint tunnel through the control management device or other entities in the network, and the source node initiates the establishment, maintenance and management of the point-to-multipoint tunnel. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] An embodiment of the present invention provides a method for establishing a point-to-multipoint tunnel in a packet network, such as figure 1 shown, including:

[0041] 100. The source node sends a point-to-multipoint tunnel establishment message, where the message carries point-to-multipoint ...

Abstract

The invention discloses a method, a system and the equipment for establishing a point-to-multi-point tunnel in a packet network. The method comprises the following steps of: sending a point-to-multi-point tunnel establishment message, which carries information parameters of the point-to-multi-point tunnel, by a source node of the point-to-multi-point tunnel; receiving a point-to-multi-point tunnel establishment response message; and reserving resources and establishing a list item. By adopting the method, system and equipment, and due to the interaction of the point-to-multi-point tunnel establishment message and the point-to-multi-point tunnel establishment response message between the source node and other nodes, the point-to-multi-point tunnel related resource reservation and the establishment of the list item are achieved, and the dynamic point-to-multi-point tunnel can be easily established in the packet network in high efficiency.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a point-to-multipoint tunnel establishment method, system and equipment in a packet network. Background technique [0002] With the development of technology, the telecommunication network has successfully completed the transition from analog technology to digital technology, and is undergoing the transition from TDM (Time-Division Multiplexing) technology to packet switching technology. ATM (Asynchronous Transfer Mode, Asynchronous Transfer Mode) packet technology is a representative of this transition. In the early 1990s, the Internet based on IP (Internet Protocol, IP protocol) packet technology achieved great success due to the application of Web technology. Therefore, the telecommunication network introduces IP packet technology, and loads all telecommunication services on the IP network, expecting to realize the transition from TDM technology to packet technology. ...
