On-Demand Service Function Chain Based on IPv6 Segment Routing

Segment routing network is the evolution and innovation of IP routing technology. With the development of mobile services and cloud computing, the segment routing technology based on IPv6 has attracted more attentions. Segment Routing over IPv6 (SRv6) is a source routing solution for IPv6 networks. SRv6 has the ability of service chain and network programmability, which can strengthen the advantages of traffic engineering and cloud network to realize various innovative applications. This paper mainly utilizes SRv6 technology to implement a Service Function Chain (SFC) combined with network security applications. Experimental results show that using SRv6 to guide the SFC path for malicious attack detection and traffic restriction can effectively improve IPv6 network security and service quality.
