提出了一种与现代路由器完全不同的新一代IP路由器体系结构--大规模并行转发和交换（MPFS）。MPFS的基本思想是将复杂的转发过程映射到多级可扩展的交换结构中，实现数据包的流水式、分布式转发。这种处理机制被称为交换转发（FIS）。通过互连多级低速组件（称为转发和交换节点（FSN）），MPFS在转发和交换性能方面实现了更好的可扩展性，就像MPP一样。重点研究了MPFS中的IPv6查找问题，提出了一种划分IPv6 FIB并将其映射到交换结构的方法。仿真和计算结果表明，MPFS路由器可以支持线速转发与100万个IPv6前缀在40 Gbps。最后提出了一种基于MPFS架构的160 Tbps核心路由器的实现方案.
A new generation architecture of IP routers called massive parallel forwarding and switching (MPFS) is proposed, which is totally different from modern routers. The basic idea of MPFS is mapping complicated forwarding process into multilevel scalable switch fabric so as to implement packet forwarding in a pipelining and distributed way. This processing mechanism is named forwarding in switching (FIS). By interconnecting multi-stage, lower speed components, called forwarding and switching nodes (FSN), MPFS achieves better scalability in forwarding and switching performance just like MPP. We put emphasis upon IPv6 lookup problem in MPFS and propose a method for partitioning IPv6 FIB and mapping them to switch fabric. Simulation and computation results suggest that MPFS routers can support line-speed forwarding with a million of IPv6 prefixes at 40 Gbps. We also propose an implementation of 160 Tbps core router based on MPFS architecture at last.
