摘要： 提出了在T比特路由器中PIM-SM组播路由协议高效实现方法。将PIM-SM协议规范中涉及数据转发的操作加以分解,并将它们分布于转发引擎和主控,转发硬件转发数据包仅需一次查表,与控制平面尽量隔离,实现了组播包的线速转发。

Abstract: This paper presents an efficient implementation of PIM-SM in tera-bit router. It decomposes forwarding functions in PIM-SMspecification and distributes them in main controller and forwarding engine. The forwarding hardware only needs one lookup to forward packet andforwarding behavior is isolated with the control panel. The forwarding speed can get line rate.
