ABSTRACT:
A network organization and routing scheme are provided. These techniques enable a network to control the paths that frames take through the network. A device transmitting a frame may add tags to the frame in order to define a particular path that the frame should take through the network. For example, the tags may indicate a link-by-link path between switches in the network. As another example, the network may be organized into one or more groups of switches, with each group and switch within a group having unique identifiers so that any given switch or port in the network may be referred to by a hierarchical identification, such as a group/switch/port identification.
