Satellite MPLS (multi-protocol label switching) network flow rate balancing method based on SDN (software defined network) controller
ActiveCN106789658AImprove service qualityImprove instabilityRadio transmissionData switching networksResource utilizationMulti protocol
The invention discloses a satellite MPLS (multi-protocol label switching) network flow rate balancing method based on an SDN (software defined network) controller. An SDN controller is put on a network edge; the control plane of network equipment is separated from the data plane; the functions of the control plane are concentrated onto a special controller, so that the equipment complexity in the network is reduced. The data plane and the control plane are decoupled, and an SDN obtains great flexibility, so that the network has the characteristics of high expandability, easy maintenance, programmable performance and open performance. According to the method, the SDN controller peripherally collects network topology and network state information from a router / interchanger in a data plane through an OpenFlow protocol of a southbound interface; through calculation, the available bandwidth condition of each link is obtained, so that whether the path jam occurs or not is judged; whether the flow rate dispatching is needed or not is judged; the goal of collecting and analyzing the whole network flow rate distribution condition in real time is achieved; the link flow rate is reasonably deployed, so that the flexible control of the network flow rate is realized; in addition, the bandwidth resource utilization rate can be better improved.
