摘要： The systems and methods disclosed herein allow for a switch (in a packet-switching network) to track buffer statistics, and trigger an event, such as a hardware interrupt or a system snapshot, in response to the buffer statistics reaching a threshold that may indicate an impending problem. Since the switch itself triggers the event to alert the network administrator, the network administrator no longer needs to sift through mountains of data to identify potential problems. Also, since the switch triggers the event prior to a problem arising, the network administrator can provide remedial action prior to a problem occurring. This type of event-triggering mechanism makes the administration of packet-switching networks more manageable.

摘要： 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.

摘要： Aspects for processing data in a server may include receiving a packet and determining a function associated with the packet. A blade server handling the function associated with the packet may be determined and the packet may be steered to that blade server. At least one association may be generated or created between a particular characteristic of a packet and a particular function associated with that packet. At least one blade server may be assigned to handle the particular function associated with a packet. The particular characteristic of the packet may include, for example, a packet type, a field within the packet and/or a flag within a portion of the packet. Steered packets may be processed by one or more blade servers that may be adapted to handle the function associated with the packets. A switch blade may be utilized to control steering of the received packets.
