摘要

为解决SONiC（software for open networking in the cloud）交换机操作系统对多模态网络（polymorphic network，PINet）中模态适配及模态管控问题，提出了一个基于P4Runtime的SONiC网元控制通道容器p4runtime-pins，使多模态网元设备可以支持多种网络模态流表的配置。p4runtime-pins容器通过gRPC服务模块实现与控制器的连接，使用邻近网元发现算法实现控制器对链路的发现。设计了网元端口更新算法解决了网元设备在实际应用环境中存在的端口变更问题。同时，针对SONiC网元交换机中硬件转发处理单元存在的流表支持性差异问题，设计了内部流表转存和gRPC网元代理功能，实现了不同网络模态流表的部署。实验结果表明，p4runtime-pins容器资源消耗低，仅占用了1.70%的CPU资源和0.45%的内存资源。同时，部署p4runtime-pins容器的SONiC网元设备能够准确地接收并配置控制器下发的流表规则，流表配置延迟仅为0.027~0.037 s。

Abstract

To address the modal adaptation and modal control issues in polymorphic network (PINet) for software for open networking in the cloud (SONiC) switch operating system

a SONiC network element control channel container called p4runtime-pins based on P4Runtime was proposed. It enabled multi-modal network element devices to support configuration of various network modal flow tables. In the p4runtime-pins container

a connection with the controller through the gRPC service module was established

a neighboring network element discovery algorithm for controller discovery of links was utilized

and a network element port update algorithm to resolve the issue of port changes in practical application environments was designed. Furthermore

to address the issue of poor support for flow table variations in the hardware forwarding processing unit of SONiC network element switches

the internal flow table dumping and gRPC network element proxy functionality was introduced in p4runtime-pins to facilitate the deployment of different network modal flow tables. Experimental results demonstrate that the p4runtime-pins container has low resource consumption

occupying only 1.70% of CPU and 0.45% of memory. Moreover

SONiC network element devices deployed with the p4runtime-pins container can accurately receive and configure flow table rules issued by the controller

with an only 0.027~0.037 s flow table configuration delay.
