Abstract

The invention discloses a service functional chain deployment method of transmission delay optimization. A service functional chain is deployed with shortening delay of the service functional chain being a main purpose, merging and splitting of network functions are combined, and meanwhile a deployment path with the shortest delay is sought. According to the method, merging and splitting algorithms are adopted for the transmission delay problem, a merging-splitting model is established, meanwhile a brand new algorithm seeking the shortest path is brought up, and p shortest paths can be sought simultaneously to deploy the service functional chain. According to the service functional chain deployment method of the transmission delay optimization, on the basis of shortening the delay of the service functional chain, a higher receptance and a shorter responding time for deploying the service functional chain are achieved. Besides, the method can avoid segmentation of resources, and maintain the robustness of networks.

Description

technical field [0001] The invention belongs to the technical field of network transmission delay optimization, and in particular relates to the design of a service function chain deployment method for transmission delay optimization. Background technique [0002] In traditional networks, network administrators directly deploy many network functions on specific hardware devices, such as network address translation, load balancing, firewalls, gateways and intrusion detection systems, etc. However, such a deployment solution leads to the rigidity of the entire network, making it difficult for the entire network to change and adapt rapidly with the development of the times and technologies. At the same time, deploying corresponding hardware for the network functions required by each network user will also consume a lot of manpower and resource costs. The entire network is too bloated and expensive, which is not conducive to the development of the network society. Moreover, wit...
