Embodiment Construction

[0037] The present invention mainly expands the widely used IGMP / MLD protocol at present, mainly expands the transmission range of the IGMP / MLD message to provide multicast support to the mobile node, and its main functions include:

[0038] (1) The IGMP / MLD host introduces node mobility status information to identify the node's mobility attributes, such as stationary, slightly mobile, medium-speed mobile, high-speed mobile, etc.;

[0039] (2) The IGMP / MLD router side sets different forwarding ranges according to the mobile state of the node, and the multicast router forwards according to the mobile state information of the node after receiving it;

[0040] (3) The IGMP / MLD router end expands the multicast state record format of the IGMP / MLD protocol, and increases the option of identifying the mobile node (such as adopting the care-of address CoA and the home address HoA) to support the management of mobile group members;

[0041] (4) The IGMP / MLD router adds a multicast forw...

Abstract

The invention relates to a moving-group member managing method based on multiple hop, which comprises: expanding the IGMP / MLD protocol and the IGMP / MLD host computer end; setting the transfer range of the host computer according to movement states of the nodes, enabling the IGMP / MLD information to carry the movement state information of the moving nodes, and expanding the IGMP / MLD router end; adding moving node identifications and multicast transfer state identifications in the multicast state information, the workflow of the multi-hop management protocol; and a router in execution group management protocol creates the moving multicast state, moving nodes create multi-hop MLD report message according to the own movement state, and the report message is required to carry the address multicast group in which the moving nodes join, the position information of the moving nodes and the identity information of the moving nodes. Aiming at establishing the group member relation for the moving nodes, thereby the multi-hop moving-group member management is provided.

Description

technical field [0001] The invention relates to the mobile multicast technology of the mobile Internet, in particular to a multi-hop-based mobile group member management method. Combined with the mobile state of the mobile node, it provides effective mobile multicast service support. Background technique [0002] With the development of mobile Internet technology, research on mobile multicast technology has become a research hotspot. Mobile multicast technology provides support for mobile multicast members on the basis of fixed multicast and mobility support protocols. Literature error! Reference source not found. Two basic mobile multicast methods are proposed, namely Bi-directional Tunneling (BT) and Remote Subscription (RS). The BT method transmits multicast data based on the unicast tunnel constructed by mobile IP, while the RS method is to rejoin the multicast group in the foreign network. The BT method has problems such as non-optimized multicast routing and multi...
