Abstract

The invention provides an SDN-based QoS-supported communication tunnel establishment method and system, which are applied to a communication network comprising an SDN exchanger and an SDN controller. The method comprises the following steps: reporting the assigned MAC address and SDN streams of an unmatched stream table to the SDN controller by the SDN exchanger; obtaining the forwarding path of the SDN streams by the SDN controller; generating a tunnel ID mapping table and a queue ID mapping table according to the forwarding path of the SDN streams and five-component group information of the SDN stream by the SDN controller and generating a corresponding stream table, wherein a priority queue is pointed out in the tunnel ID; issuing the stream table to the SDN exchanger by the SDN controller; obtaining an output queue and an output port by the SDN exchanger. According to the invention, on the basis of the SDN framework, establishment of a communication tunnel is completed by the SDN controller in a unified manner, the communication tunnel is established according to DSCP fields of the IP header of the SDN stream, the priority queue is pointed out and end-to-end QoS service is provided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to the technical field, and specifically relates to a method and system for establishing a communication tunnel supporting QoS based on SDN. Background technique [0002] GRE provides a mechanism for encapsulating packets of one protocol into packets of another protocol, so that packets can be transmitted on heterogeneous networks. However, the GRE mechanism is simple and cannot guarantee that packets will arrive at the destination correctly, and does not provide QoS features. Traditional GRE encapsulates the datagrams of certain network layer protocols so that these encapsulated datagrams can be transmitted in another network layer protocol. If a packet is to be transmitted in the GRE Tunnel, it must be encapsulated and Decapsulates two processes. [0003] Traditional GRE is characterized by a simple mechanism, a small CPU burden on the devices at both ends of the t...
