Problems solved by technology

However, due to the distributed control adopted by MPLS, it is difficult to perceive link bandwidth utilization and collect and analyze the traffic distribution of the entire network.
Therefore, although the existing MPLS network can improve the utilization rate of network bandwidth resources, it still has a lot of room for improvement in the utilization rate of network bandwidth resources.

Abstract

An SDN-based MPLS network control system and method. The SDN-based MPLS network control system includes: SDN controller, which is used to deliver IP forwarding table, label forwarding table and flow table to the switch. The flow table includes matching IP packets according to the destination IP and matching labeled packets according to the label. ;The switch includes a border switching router and a label switching router; the border switching router is used to receive the IP forwarding table, label forwarding table and flow table, and process the received message according to the flow table; the label switching router is used to receive the label forwarding table And the flow table, and process the received message according to the flow table. The technical scheme of the invention can make full use of the link resources of the whole network to achieve better network flow optimization.

Description

technical field [0001] The invention relates to a computer network technology, in particular to an SDN-based MPLS network control system and method. Background technique [0002] Currently, data center traffic is mainly divided into two types, north-south traffic and east-west traffic. North-south traffic is mainly for users to access data center content, and east-west traffic includes: data center cloud resource pool (in the same data center or across data centers) synchronization, backup, CDN (Content Delivery Network, content distribution network) traffic push, etc. For the above-mentioned types of traffic, the traffic engineering mechanism is rarely used at present, resulting in the problem of low utilization efficiency of links within the data center or between data centers, which is mainly reflected in two aspects: for synchronization and backup traffic, in most cases The link bandwidth utilization rate of these traffic is very low, resulting in waste of network bandw...
