Embodiment 1
[0067] Such as figure 1 As shown, Embodiment 1 of the present invention provides an intelligent routing method for an information transmission platform, including the following steps:
[0068] S1: Collect network status information between network nodes in real time, and select at least one first-class key node and at least one second-class key node for each network node according to the network status information;
[0069] The network state information specifically includes the packet loss rate, network delay, network jitter, bandwidth, etc. in the media information transmission process, and the transmission effect of the media information can be judged accordingly; in the embodiment of the present invention, each network node corresponds to a network domain, A network detection service is deployed in each network domain; the network detection service in each network node sends RTCP / SR (RTP Control Protocol, RTP control protocol; SenderReport, sender report) to other network ...
Embodiment 2
[0108] Such as Figure 4 As shown, Embodiment 2 provides an intelligent routing system for an information transmission platform, including the following parts:
[0109] The information collection module 1 is used to collect network status information between network nodes in real time;
[0110] The key node selection module 2 is used to select at least one type-1 key node and at least one type-2 key node for each network node according to the network state information;
[0111] The path calculation module 3 is used to calculate the available path for each network node according to the key node, and generate a path table, the available path must pass through at least one type-1 key node, and does not pass through any type-2 key node;
[0112] The routing table update module 4 is used to send information related to the network node in the routing table to each network node, so that each network node creates a new local routing table;
[0113] The media stream forwarding module...
Embodiment 3
[0116] Such as Figure 5 As shown, this embodiment 3 provides an intelligent routing system of an information transmission platform on the basis of embodiment 2, and this embodiment 3 further defines that the key node selection module 2 includes the following parts:
[0117] The importance calculation unit 21 is used to calculate the importance S of all network nodes in the network according to the principle of structural holes, and the calculation method is as follows:
[0118] Establish network node adjacency matrix A=[a ij ] n×n , where n is the number of nodes in the network; when node i and node j have links, a ij = 1; when there is no link between node i and node j, a ij = 0;
[0119] The channel validity P and node validity V between adjacent network nodes in the network are calculated according to the following formula:
[0120]
[0121]
[0122] Among them, w ij is the channel bandwidth from node i to node j, Γ(i) is the set of adjacent nodes of node i, n ...
