Abstract
A reconfigurable match table (RMT) is a programmable pipeline architecture for packet processing. In order to enable the programmable data plane to support segment routing IPv6 (SRv6) and other network protocols, this paper extends the deparser based on RMT. The paper uses the extended deparser and two RMT pipelines to build a protocol-independent network slice programmable data plane model named as the programmable SRv6 processor. We design it primarily for segment identifier (SID) processing of SRv6. We have proved that it can support SRv6, multiple semantics for SIDs, micro segment ID, multi-protocol label switching, and a service function chain (SFC). This architecture has broad application prospects. Experimental results on an FPGA showed that the extended deparser could achieve 100 Gbps throughput for 512B packets with few resources.
