Abstract
Official abstract text for this publication.
In a network device packets are marked with sequence identifiers at ingress of the device, switched through a plurality of switching planes and re-sequenced on a per flow basis at egress of the device. The re-sequencing system includes a controller that allocates to each received data packet a temporary storage location in a packet buffer. A plurality of output registers are provided, with each one associated with a flow. A pointer uses predefined parameters to point to an output register that has been previously assigned to receive data packets from the corresponding flow. Parameters in the pointed output register are correlated with parameters in a received packet to determine if the received packet is next in sequence to packets processed through a particular queue.
First claim
Opening claim text (preview).
Having thus described our invention, what we claim is as follows: 1. A system for resequencing per flow data packets received by at least one destination egress adapter comprising: a plurality of output registers with each register dynamically assigned to store received data packets from one of a plurality of flows, wherein each of the output registers further comprises: a packet sequence number and a packet buffer identifier for an in-process data packet; and a valid-bit latc…
