多协议标签交换(MPLS)技术实现IP网络的流量工程、虚拟专网、服务质量保证。本文建立了标签交换路由器(LSR)功能模型,以此模型基础设计了基于软硬件协同工作的LSR架构。利用灵活的软件处理复杂的控制平面协议,硬件高速的数据处理能力兼顾转发平面对实时性的要求。
The MPLS technology supports the traffic engineering and realizes VPN and QoS. This paper introduces the architecture of MPLS and proposes the function module of the label switch router, and a structure based on software hardware cooperation is designed. The software is used for the complex protocol in the control plane, and the high-speed hardware supports the data plane to meet the real-time requirement.
