Abstract:
1. A method comprising: receiving, using a computer processor, at a receiver data packets having different data link layer structures on a single data link at a data link layer via a sender through a Fibre Channel over Convergence Enhanced Ethernet (FCoCEE) and transmitting at least one of an acknowledge signal (ACK) and a no acknowledge signal (NAK) in response to a sequence number in the data packets; retransmitting the data packets via a replay buffer that is sized by at least one of length of the 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; indicating additional reliable link layer sequence number bytes via a delimiter, and 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 modifying the data packet's EtherType field so each data packet comprises a sequence number via the sender.
