Abstract:
1. A system comprising: a replay buffer, using a replay computer processor, to retransmit data packets in a Fibre Channel over Convergence Enhanced Ethernet (FCoCEE) network in which data packets having different data link layer structures are transmitted by a sender and received by a receiver at a data link layer; wherein the receiver transmits at least one of an acknowledge signal (ACK) and a no acknowledge signal (NAK) in response to a sequence number in the data packets; wherein the replay buffer is sized by at least one of length of a single data link, data rate of the single data link, at least one of ACK and NAK processing time at either the sender or the receiver, and at least one of a threshold time for transmission and reception of the data packets; a delimiter to indicate additional reliable link layer sequence number bytes; wherein if a reliable link layer is enabled, sequential Packet Sequence Numbers are at least one of grouped together as a common traffic class and given priority for at least one of this frame type and this ACK type; and wherein the sender modifies the data packet's EtherType field so each data packet comprises a sequence number.
