Abstract: A system and method is provided for creating and detecting prefix-based entropy labels in a multi-protocol label switching communication network. Each label in a label stack is provided with at least a common prefix field and a computed hash field without the use of entropy label indicators (ELIs). Label stacks generated are processed by transit LSRs in an MPLS communications network where the transit LSR uses the first N labels of the label stack to determine the hash computations for load balancing. By scattering prefix-based entropy labels throughout the label stack, the transit LSR uses one or more prefix-based entropy labels for the hash computation.

Abstract: Disclosed are various embodiments for multi-homing in an extended bridge, including both multi-homing of port extenders and multi-homing of end stations. In various embodiments, a controlling bridge device receives a packet via an ingress virtual port and determines a destination virtual port link aggregation group based at least in part on a destination media access control (MAC) address of an end station in the packet. The controlling bridge device selects one of multiple egress virtual ports of the destination virtual port link aggregation group. The end station of the extended bridge is reachable through any of the egress virtual ports of the destination virtual port link aggregation group. The controlling bridge device forwards the packet through the selected egress virtual port, and the forwarded packet includes an identifier of a destination virtual port to which the end station is connected.

Abstract: A network device, such as a switch, implements enhanced linked-list processing features. The processing features facilitate packet manipulation actions performed, e.g., by hardware or software processes. Hardware processes may run for egress ports, for example, to traverse the linked-lists to apply the packet manipulation actions on packets before sending packets out of the ports.
