Abstract: A method includes receiving multicast traffic intended for host devices; identifying a flow associated with the multicast traffic; retrieving information associated with a group of multicast trees, where the group of multicast trees includes information associated with a group of I/O units, associated with a network node; identifying a particular tree that corresponds to the identified flow, where the particular tree includes information associated with a set of I/O units; and transferring the multicast traffic to an I/O unit, of the set of I/O units, based on the identification of the particular tree, where the transferring enables the I/O unit to send a copy of the multicast traffic to other I/O units of the set of I/O units, and the set of I/O units to process the multicast traffic in a manner that utilizes bandwidth or processing resources in a controlled manner and to send a copy of the multicast traffic to each of the host devices.

Abstract translation: 一种方法包括接收用于主机设备的多播流量; 识别与多播流量相关联的流; 检索与一组多播树相关联的信息，其中所述多播树组包括与网络节点相关联的与一组I / O单元相关联的信息; 识别对应于所识别的流的特定树，其中所述特定树包括与一组I / O单元相关联的信息; 并且基于特定树的标识将组播流量传送到I / O单元集合的I / O单元，其中传输使I / O单元能够将多播业务的副本发送到其他I 一组I / O单元的O / O单元，以及以受控方式利用带宽或处理资源的方式处理组播流量的I / O单元组，并将多播流量的副本发送到 主机设备。

Abstract: A multi-router system is described in which hardware and software components of one or more standalone routers can be partitioned into multiple logical routers. The multiple logical routers are isolated from each other in terms of routing and forwarding functions yet allow network interfaces to be shared between the logical routers. Moreover, different logical routers can share network interfaces without impacting the ability of any of the logical routers to be independently scaled to meet the bandwidth demands of the customers serviced by the logical router.
