Abstract
A mechanism provides for sending an envelope and replying to an envelope. A transmitter is configured to send an envelope. A receiver is coupled to the transmitter, wherein the receiver is configured to receive the envelope and generate a reply envelope. A send buffer is coupled to the transmitter. A receive buffer is coupled to the receiver. A retry timer is coupled to the transmitter, wherein the retry timer is configured to reset upon the receipt of a reply envelope correlated to the transmit envelope. The transmitter is configured to retransmit an envelope if the transmitter does not receive a corresponding reply envelope within a selected time period as determined by the retry timer. This leads to a decrease in the total number of envelopes, transmitted from both the transmitter and the receiver.
