Abstract: IEEE 802.1Q and Enhanced Transmission Selection provide only eight different traffic classes that may be used to control bandwidth in a particular physical connection (or link). Instead of relying only on these eight traffic classes to manage bandwidth, the embodiments discussed herein disclose using an Enhanced Transmission Selection scheduler that permits a network device to set the bandwidth for an individual virtual LAN. Allocating bandwidth in a port based on a virtual LAN ID permits a network device to allocate bandwidth to, e.g., millions of unique virtual LANs. Thus, this technique may increase the granular control of the network fabric and its performance.

Abstract: In one embodiment, a computer program product includes a computer readable storage medium having program instructions embodied therewith. The embodied program instructions are readable/executable by a processor to receive, by the processor, a packet via a network fabric, the network fabric having a plurality of interconnected fabric switches. The embodied program instructions are also readable/executable by the processor to determine, by the processor, a path through the network fabric by consulting a source-routing table. Moreover, the embodied program instructions are readable/executable by the processor to store, by the processor, source-routing information to a packet header for the packet, the source-routing information including the path. In addition, the embodied program instructions are readable/executable by the processor to send, by the processor, the packet according to an indication in the source-routing information.
