MPLS network control system and method based on SDN

Abstract

The invention discloses an MPLS (Multi-protocol Label Switching) network control system and an MPLS network control method based on SDN (Software Defined Network). The MPLS network control system based on SDN comprises an SDN controller, wherein the SDN controller is used for issuing an IP forwarding table, a label forwarding table and a flow table to a switch; the flow table comprises an IP message for matching according to the targeted IP and a message with the label matching according to the label; the switch comprises a boundary switch router and a label switch router; the boundary switch router is used for receiving the IP forwarding table, the label forwarding table and the flow table, and processing the received messages according to the flow table; the label switch router is used for receiving the label forwarding table and the flow table, and processing the received messages according to the flow table. The technical scheme disclosed by the invention can fully utilize the link resources in the whole network to achieve a better network flow optimization effect.

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...

AI Technical Summary

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.
