    • One embodiment of the present invention provides a computing system. The computing system includes a processor, a memory, a logical switch management mechanism, and a layer-2 path management mechanism. The logical switch management mechanism operates the computing system in conjunction with a plurality of remote switches as a single logical switch. The layer-2 path management mechanism includes a path calculation mechanism and a layer-2 forwarding table. The path calculation mechanism calculates layer-2 shortest paths among the computing system and the remote switches. The layer-2 forwarding table is for a first switch in the plurality of remote switches and created based on one or more of the shortest paths, wherein a respective entry in the forwarding table corresponds to a layer-2 network address. The layer-2 path management mechanism suppresses advertisement of the shortest paths outside of the logical switch, thereby hiding internal paths of the logical switch.
    • 本发明的一个实施例提供一种计算系统。 计算系统包括处理器,存储器,逻辑交换机管理机制和第二层路径管理机制。 逻辑交换机管理机制将计算系统结合多个远程交换机作为单个逻辑交换机进行操作。 二层路径管理机制包括路径计算机制和二层转发表。 路径计算机制计算计算系统和远程交换机之间的第二层最短路径。 第二层转发表用于多个远程交换机中的第一交换机,并且基于一个或多个最短路径创建,其中转发表中的相应条目对应于二层网络地址。 二层路径管理机制抑制逻辑交换机以外的最短路径的通告,从而隐藏逻辑交换机的内部路径。
