Research on the architecture of address semantics-driven service function chaining

  • Received Date: 2020-04-18
  • To address the shortcomings that existed in the establishment of SFC service function path, such as inflexible dataflow classification and high cost of flow steering, an address semantics-driven service function chaining architecture scheme was proposed.The scheme creatively encoded multiple semantic attributes of users into the IP source address,andused a software-defined network (SDN) architecture to form and issue policies based on user needs on a customized central control server, thereby instructing the flow classifier to flexibly classify data flows based on the semantic attributes of addresses.At the same time,SDN forwarding equipment established the data flow diversion mechanism based on IPv6 source routing technology.A dynamic optimization model of network resources under multiple constraints was constructedto achieve dynamic optimization of network resources carried by the service function chain.Experiment results showed that the scheme could build a dynamic, flexible, multi-granularity, load-balancing service function chain.Compared with the same type of scheme, the service function chain constructed by the schemewas more efficient and had less delay, and could be the best candidate for large ISP/ICP to provide diversified and intelligent network services.
