多服务交换资源虚拟分割算法的研究

为用户或应用提供多样性服务是网络发展的趋势，不同的服务需要相应的网络转发或交换机制支持，实现多服务交换或转发的关键是资源分配和管理，该文提出一种支持面向应用的多服务交换路由器的资源虚拟分割算法，它结合可编程路由器，根据不同应用的转发需求，为不同转发服务分配一定范围的虚拟资源区间，该虚拟分割区间能够隔离和保护不同应用网络流，为其提供一定的服务质量保障，并使服务间能够可控，动态地共享多余的资源。

Research on Virtual Partitioning Algorithm of Multiservice Switching

It is a trend that networks provides users or applications with diverse services, and various services require adaptive traffic forwarding or switching mechanism. Resource management is the key for realization of multiservice switching or forwarding. This paper presents a resource virtual partitioning algorithm that supports application-specific multiservice switching router. Integrated with programmable router, the algorithm allocates a certain range of virtual resources for services according to the requirement of applications. The virtual partition can provide isolation and protection for different application traffic, some guaranteed QoS, and controllable resource sharing between services.
