Internet正从单一服务形式的网络逐步向多服务、智能化网络发展。根据应用的需求和特征,通过可编程机制动态形成适应应用的报文转发机制,是未来路由器发展的趋势。该文提出了一种面向应用转发的多服务虚拟交换路由器结构:PVSMR,并对其主要构成及其关键实现技术进行了深入的探讨。PVSMR基于资源分割形成的虚拟转发结构,它能够提供与多类应用相适应的、灵活的报文处理和转发控制能力。 The Internet is evolving from a single service network to multi-service and intelligent networks. According to the needs and characteristics of the application, through the programmable mechanism to dynamically adapt to the application of packet forwarding mechanism is the future trend of the development of the router. This paper proposes a multi-service virtual switch router architecture for application forwarding: PVSMR, and discusses its main components and key implementation technologies. Based on the virtual forwarding structure formed by resource division, PVSMR can provide flexible packet processing and forwarding control adaptable to many types of applications.
