Network slice programmable data plane model

RMT (reconfigurable match table) is a programmable pipeline architecture for packet processing. In order to enable the programmable data plane to support more different network protocols, the deparser based on RMT was extended. A protocol-independent network slicing programmable data plane model was formed by using the extended deparser and two RMT pipelines. Since reduced instruction set was used in RMT architecture and complex instruction set was used in the extended deparser, the extended architecture was called HiRMT (hybrid-instruction RMT). HiRMT can support segment routing IPv6, multiple semantics for SID (segment ID), micro SID, multi-protocol label switching and virtual extensible local area network. This architecture has broad application prospects. The performance of the deparser module was tested on the Corundum prototype platform, and the results show that the extended deparser can process the packet size up to 512 B with a throughput of 100 Gbit/s with fewer resources.
