Embodiment
As shown in Figure 1, a kind of distribution method of network traffics comprises:
By the technical scheme of the invention described above embodiment as can be seen: between source node and destination node, set up many alternative routes, adjust each link traffic load in the network in conjunction with hopfield neural network algorithm and flow deviation algorithm, carry out the assignment of traffic adjustment, to reach the optimization network transfer delay.And, realized the routing optimality under many alternative paths situation.
Optionally, in the above-mentioned steps 11, when the original allocation network traffics, network traffics can be assigned on the one or more alternative routed path, and are unrestricted.
Need to prove,, realize that promptly network transfer delay satisfies pre-provisioning request owing to can not guarantee once to adjust the network traffics of distributing on the alternative routed path.After each network traffics were adjusted, the network traffics distribution changed, and the propagation delay time of each link (link between the adjacent node) also can change, and then needed to continue to adjust.Therefore, in the step 14, continue to determine optimum routed path in the alternative routed path, continue to adjust network traffics on the alternative routed path by the FD algorithm then, satisfy pre-provisioning request up to network transfer delay by the hopfield neural network algorithm.
In the step 14, it can be that network transfer delay satisfies certain threshold values that network transfer delay satisfies pre-provisioning request, or the like.
As seen, initial optimum routed path and optimum routed path are represented the preferred routed path of different phase, do not give unnecessary details at this.
Concrete, between the destination node of the source node of network and network, set up many alternative routed paths in the above-mentioned steps 11, can comprise:
Source node sends a plurality of route exploration bags and determines that with hop-by-hop source node arrives the intermediate node of destination node, carries intermediate node information and link information during route exploration bag process intermediate node.
Destination node is set up many first alternative routed paths according to the nodal information and the link information that carry in a plurality of route exploration bags that receive.
Destination node sends a plurality of acknowledge messages by many first alternative routed paths, carries the intermediate node information of renewal and the link information of renewal during acknowledge message process intermediate node.

Step 32, after intermediate node is received the route exploration bag, according to the network performance parameter that is kept at this node for example link channel capacity, load, time delay etc. calculate next-hop nodes, and the network informations such as selected link information, nodal information are kept in the route exploration bag.Route exploration bag hop-by-hop is selected node, and collection network information, and when the route exploration bag arrived destination node, the route exploration bag had just intactly been preserved the information of whole piece route.
Step 33, destination node can be set first timer after receiving first route exploration bag, the route that the route exploration bag of receiving before first timer is overtime from same source node is comprised is as the first alternative routed path, and the first alternative routed path can be one or more.Exemplary, as shown in Figure 2, the first alternative routed path as, source node 21 is by 3 paths shown in intermediate node 221, intermediate node 222, intermediate node 223 and 23 arrows of destination node.The route exploration bag of receiving after overtime can directly abandon.
Step 34, destination node sends ACK (Acknowledge) acknowledge message according to the first alternative routed path.The first alternative routing iinformation is included in the corresponding ACK message.
Step 35, ACK message is returned source node along the first alternative route transmission, and upgrades link and nodal information through intermediate node the time, upgrades link and nodal information and already is included in the corresponding ACK message.
Step 36, source node can be set second timer after receiving first ACK message, and the route that the ACK message of receiving before second timer is overtime is comprised is as alternative routed path, and alternative routed path can be one or more.Directly abandon ACK message after overtime.
So far, source node can be set up many alternative routed paths of source node to destination node according to routing iinformation in the ACK message.
