摘　　要：随着云和互联网的快速发展,用户对网络业务的需求也呈现出多样化的趋势,为实现不同业务的多样化需求,SRv6网络切片应运而生。基于网络处理器的SRv6网络切片功能在转发过程中引入全局切片标识,并将其封装于IPv6的逐跳扩展头中。通过切片标识与VLAN子接口的绑定关系来区分不同的转发资源,并与子接口限速相结合实现对不同业务流量的差异化控制,达到提高网络规划与管理的便捷性,减少网络扩展压力的目的,以满足同一张网络上不同业务的差异化需求。With the rapid development of cloud and Internet,users’ demand for network services also shows a diversified trend.In order to meet the diversified needs of different services,SRv6 network slicing came into being.The SRv6 network slicing function based on the Network Processor Chip introduces a global slice identifier in the forwarding process.The slice identifier is encapsulated in the IPv6 Hop by Hop Extension Header.Slicing is bound with VLAN to distinguish different forwarding resource interfaces,and combined with sub interface speed limit to realize differential control of different service flows.To improve the convenience of network planning and management,reduce the pressure of network expansion,and meet the differentiated needs of different services on the same network.
