Embodiment Construction

[0045] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the implementations shown and described in the drawings are only exemplary, intended to explain the principle and spirit of the present invention, rather than limit the scope of the present invention.

[0046] The embodiment of the present invention provides an adaptive multicast routing selection method, such as figure 1 As shown, the following steps S1-S8 are included:

[0047] S1. Run the RTP protocol in the multicast mode on the server side, and send the stream media data to the multicast channel identified by the multicast address. This design helps the data sent by the server not be affected by the number of receivers.

[0048] S2. Taking each user sending a multicast request service within the multicast range as a member of a multicast group, and counting the number N of multicast group members.

[0049] S3. D...

Abstract

The invention discloses a self-adaptive multicast routing selection method. The method comprises the following steps: self-adaptively selecting an optimal routing method according to the current specific multicast group and network environment, selecting a core-based discovery method for the multicast group with large multicast group member density change rate to perform the data transmission, selecting a flooding and cropping method for the multicast group with relatively dens multicast group member to perform data transmission, and selecting a tunnel method for the multicast group with relatively dispersed multicast group member to perform data transmission. The method is relatively high in flexibility, and capable of playing the multicast technology advantage for the maximum efficiencyunder various environments. Furthermore, the method can be served to the user of the unicast network, the seamless connection with the existing multicast technology and the application layer technology can be realized, so that the multicast routing selection and the existing multicast technology and the application layer technology can be commonly used, and the application range is extensive.

Description

technical field [0001] The invention belongs to the technical field of wireless network communication, and in particular relates to the design of an adaptive multicast routing selection method. Background technique [0002] In 1988, Deering proposed the concept of IP multicast, and since then IP multicast technology has received widespread attention. Multicast is between unicast communication and broadcast communication. It can send data packets sent by the sender to a group of receivers scattered in different subnets. The basic concept of multicast is "group". A multicast group is a group of receivers who want to receive a specific data stream. The group has no physical or geographic boundaries: hosts in the group can be located anywhere on the Internet or private network. Each node in a multicast group is called a multicast group member. [0003] In various applications of multicast, unicast can be realized, but as the number of receivers increases, the number of data p...
