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: A system and method performs packet analysis in a distributed communication network. Packet processors tap into data packet flow at various points in the distributed network. The packet processors processes data packets from the packet flow and select a set of packets using a packet signature function and packet selection criteria. A packet record is created by each packet processor and sent to other packet processors in the distributed network. The other packet processors add data to the packet record for the same set of packets. The packet records are analyzed to gather comparative data to identify problems in the network.
