Abstract

SRv6 has been constrained in its deployment in a large-scale operator network since the lengthy packet header decreases the forwarding performance in network processors. In this paper, we analyze in depth and reveal the limiting factors on network processor performance introduced by the long SRv6 packet header. The required resources for processing SRv6 and G-SRv6 packet headers are also compared in terms of cache space, processing bandwidth and routing table in network processors. By constructing an experimental network to measure the throughput and forwarding latency of network processors when handling SRv6 and G-SRv6 packets, the experimental results show that G-SRv6 can improve the packet throughput of network processors and reduce packet forwarding latency, which is beneficial for the largescale deployment of SRv6. This paper provides valuable insights and guidance for the design of network processor architectures targeted at G-SRv6 applications.
