Embodiment

[0059] In this embodiment, four kinds of services in the 3G network are used as illustrative examples, as shown in Table 1, and the TOS domains in the IP protocol of these four kinds of service messages are respectively set with corresponding priorities, and the time delay requirements are the highest The TOS field of conversational service packets is set to 4, indicating that this type of packet is the highest priority service packet, and the TOS field values ​​of streaming media service packets, interactive service packets, and background service packets are respectively set to 3 , 2 and 1. The controller software uses the open source software Floodlight, and the OpenFlow switch uses the open source software defined network switch OpenvSwitch.

Abstract

The invention discloses a QoS control method for distinguishing business priorities in an SDN network. Firstly, the data business in the SDN network is divided into business priorities according to the required service quality, and then in the differentiated routing, the highest priority The business data flow takes the link congestion measurement as the link cost cost, and takes the delay required by the highest priority business data flow as the constraint condition, and uses the Lagrangian relaxation aggregation cost algorithm for routing, and uses the hop count as the Routing based on the shortest path algorithm based on cost; in differentiated queue scheduling, differential queue scheduling is performed based on the business priority. The present invention not only guarantees the end-to-end time delay of the highest priority service, but also guarantees the different service quality of other different priority services. At the same time, the highest priority service is routed to a low-congestion path, which improves the network Bandwidth utilization and throughput of network data transfers.

Description

technical field [0001] The present invention relates to the technical field of QoS (Quality Of Service, service quality) control, in particular to a QoS control method for distinguishing business priorities in SDN (Software Defined Network, software defined network). Background technique [0002] The rapid development of the Internet has led to a rapid growth of service data streams transmitted in the network, and at the same time, the types of services have also increased sharply. Especially with the rise of multimedia services, the interaction of network services is more vivid and real-time, which makes business users put forward higher requirements for business service quality. Although the rapid development of network infrastructure construction has greatly improved network bandwidth and network speed, the business data that needs to be transmitted by the network is also growing rapidly. In the case of limited network resources, when a large amount of multiple business ...
