Problems solved by technology

[0021] The present invention provides a method and system for realizing cross-domain multicast services between an ad hoc network and a fixed network, so as to solve the problem in the prior art that cross-domain multicast services cannot be effectively managed;
[0022] Further, solve the problem that in the prior art, the load cannot be balanced and optimized, so that the cross-domain active multicast routing cannot be effectively switched

Embodiment Construction

[0086] The present invention realizes smooth interaction of multicast service between MANET and fixed network through ad hoc network (MANET) and fixed network interaction framework (Multicast Architecture between MANET and Fixed network, MAMF), and realizes multicast service in fixed network and ad hoc network Seamless connection enables multicast services to span different networks.

[0087] MAMF is established based on the interconnection between MANET and fixed network. The multicast border gateway (MBG) defaults to select the border gateway node as the interactive agent of the multicast service. On the basis of the original border gateway, the cross-domain (or Called cross-network) multicast service support.

[0088] In order to realize the support for cross-network multicast service interaction, in the present invention, MANET can realize the automatic configuration of IPv6 address, can realize the connection with fixed network through MBG and AR, MANET supports authentic...

Abstract

This invention discloses one method to realize overly set broadcast business in self set network and fix network, which comprises the following steps: sending play router information from set source and the MANET receives the set play router found message boundary network gate one BG to convert the message into fix network identifiable set play router message and to send to interface router and the said AR uses fix network set play router to transfer router message to form set broad transfer structure. This invention also discloses one communication system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a system for realizing cross-domain multicast services between an ad hoc network (MANET) and a fixed network. Background technique [0002] Ad hoc network (MANET), as a distributed wireless mobile network without central management, has always been the focus of research in the industry. The initial research focused on the military, with the isolated MANET as the object for the cluster communication environment. With the rapid development of network technology, the demand for MANET in civilian use is increasing day by day. In many applications of MANET (audio, video, etc.), nodes need to complete a given task through group cooperation, and multicast, as a technology that saves bandwidth resources and can effectively forward data, is very suitable for the characteristics of MANET, so Multicast has broad application prospects in MANET. MANET is an important par...
