摘要： A data segment of a data packet destined for an egress port of an egress node may be received at a first ingress node. An egress statement vector and an ingress statement vector may be identified at the first ingress node. A determination may be made, based on the egress statement vector and ingress statement vector, whether the first ingress node is authorized to transfer the data segment to the egress port before the other data segments of the data packet are received at the first ingress node. The data segment may be transferred to the egress port before the other data segments of the data packet are received at the first ingress node when the determination indicates the first ingress node is authorized. The data segment may be stored in a buffer of the first ingress node when the determination indicates the first ingress node is not authorized.

摘要： A system and method for achieving lossless packet delivery in packet rate oversubscribed systems. Link-level packet rate control can be effected through the transmission of packet rate control messages to link partners of an oversubscribed system. The transmission of packet rate control messages can be triggered upon a determination that a packet arrival rate over a set of ingress ports exceeds a packet processing rate of a packet processing unit bound to the set of ingress ports. In one embodiment, the packet processing rate is artificially reduced due to a reduction in power consumption in the oversubscribed system.

摘要： While transmitting a first Ethernet frame from the first buffer onto an Ethernet link, a first Ethernet device may stop transmitting the first frame prior to completing transmission of the frame. The first Ethernet device may then transmit a second frame from a second buffer onto the Ethernet link. The first Ethernet device may resume transmission of the first frame from the first buffer onto the Ethernet link. A second Ethernet device may receive, via the Ethernet link, a first portion of a first Ethernet frame and store the first portion of the first Ethernet frame in a first buffer. The second Ethernet device may then receive, via the Ethernet link, a second Ethernet frame and store the second Ethernet frame in a second buffer. The second Ethernet device may then receive, via the Ethernet link, a second portion of the first Ethernet frame and append it to the contents of the first buffer.

摘要： Various example embodiments are disclosed. According to an example embodiment, an apparatus may include a switch fabric. The switch fabric may be configured to assign packets to either a first flow set or a second flow set based on fields included in the packets. The switch fabric may also be configured to send a first packet from the first flow set to a first flow set destination via a first path. The switch fabric may also be configured to determine, based at least in part on delays of the first path and a second path, whether sending a second packet from the first flow set to the first flow set destination via a second path will result in the second packet reaching the first flow set destination after the first packet reaches the first flow set destination, the second packet having been received by the router after the first packet. The switch fabric may also be configured to send the second packet to the first flow set destination via the second path based at least in part on the determining that sending the second packet from the first flow set to the first flow set destination via a second path will result in the second packet reaching the first flow set destination after the first packet reaches the first flow set destination.

摘要： Methods and apparatus for dynamic load balancing using virtual link credit accounting are disclosed. An example method includes receiving, at a network device, a data packet to be communicated using an aggregation group, the aggregation group including a plurality of virtual links having a common destination. The example method further includes determining a hash value based on the packet and determining an assigned virtual link of the plurality of virtual links based on the hash value. The example method also includes reducing a number of available transmission credits for the aggregation group and reducing a number of available transmission credits for the assigned virtual link. The example method still further includes communicating the packet to another network device using the assigned virtual link.

摘要： A data segment of a data packet destined for an egress port of an egress node may be received at a first ingress node. An egress statement vector and an ingress statement vector may be identified at the first ingress node. A determination may be made, based on the egress statement vector and ingress statement vector, whether the first ingress node is authorized to transfer the data segment to the egress port before the other data segments of the data packet are received at the first ingress node. The data segment may be transferred to the egress port before the other data segments of the data packet are received at the first ingress node when the determination indicates the first ingress node is authorized. The data segment may be stored in a buffer of the first ingress node when the determination indicates the first ingress node is not authorized.
