Problems solved by technology

[0003] Traditional routing solutions face many difficulties. The network architecture and protocol design have limitations, and there are problems such as slow convergence speed of routing algorithms and difficulty in providing network transmission guarantees for different services.
Most of the traffic-based routing algorithms used in the past use the shortest path algorithm measured by the number of hops, w

Embodiment

[0057] The experiment is carried out using the NSF network topology with 14 nodes and 21 links, assuming that the number of application categories with different QoS requirements is 3 (ie K=3), and 3 traffic matrices TM are generated. Such as figure 1 As shown, collect data packets, network status, traffic matrix TM and other information from forwarding devices and controllers; the traffic demand of the entire network TM 1 ,TM 2 ,TM 3 As the input of DDPG, the link weights corresponding to different service flows are used as output, and W 1 , W 2 , W 3 ; According to the link weight W corresponding to each service 1 , W 2 , W 3 Calculate the shortest weighted path separately, and obtain the next hop port of each service as the routing forwarding strategy R 1 , R 2 , R 3 ; publish routing policy R 1 , R 2 , R 3 Go to the network routing node, perform traffic transmission, and obtain the forwarding port; count the delay, jitter, and packet loss rate of each business...

Abstract

The invention discloses a network routing forwarding method and system based on business service quality requirements, and belongs to the field of network communication. Time delay, jitter and bandwidth constraints are adopted to express the requirements for the service quality. Compared with the prior art, the service quality requirements are expressed by adopting time delay, jitter and bandwidthconstraints, so the service quality requirements are more accurately matched, the service requirements are expressed, different types of services are refined and distinguished, and the differentiatedrequirements of diversified services are realized. The specific service quality constraint index is embedded into the BPP metadata. A forwarding node directly knows the specific service quality indexrequirements by extracting the BPP header information, so that the routing strategy and the reward standard are customized according to the service quality requirement indexes, the optimal routing configuration under the requirements is obtained, and the differentiated requirements of diversified services are realized. A DDPG method based on deep reinforcement learning is adopted, the learning target is the weight of each link, the trained link weights are used for executing routing algorithms such as OSPF and the like for routing, an optimal network routing strategy is obtained, and the network utility is improved.

Description

technical field [0001] The invention belongs to the technical field of network communication, and more specifically relates to a method and system for network routing and forwarding based on business service quality requirements. Background technique [0002] With the vigorous development of the Internet and the emergence of new technologies, network applications have changed from single data transmission to diversified network application scenarios, and traditional networks are also unable to support the multi-dimensional and differentiated network requirements of new Internet formats. In the Industrial Internet, business service quality is directly related to production safety and public safety. Different application scenarios have different emphasis on service response time, delay tolerance, service security level, and service reliability. For example, in precision instrument manufacturing, etc. In industrial scenarios, the bearer requirements for low latency, low jitter,...
