Abstract
A method and structure for the handling and discarding of packets in a packet data network. The method includes a packet data network receiving one or more packets from one or more remote locations and initiating a transfer of a packet of the one or more packets to a remote destination. The remote destination is operable to act as a destination port of a switch. The transfer of the packet is initiated while the packet of the one or more packets is being received, and the packet validity is also checked while the transfer of the packet is initiated. If the packet is invalid, the transfer of the packet of the one or more packets to the remote destination is canceled. Determining packet validity includes inspection of a packet header. The structure has a receive link determining packet validity and passing this error signal to a packet processor. The packet processor has a packet transfer request generator, a packet checker, packet reader, packet memory and tag memory. The packet transfer request generator initiates a transfer request over a switch with a remote destination. While the request is processed, the packet checker verifies packet correctness and stores the packet data for transmission to the remote destination. If a packet is in error, a bad tag is set and the packet transfer is aborted.
