Abstract
Methods and apparatus that allow recovery in the event that sequence counts used on receive and transmit sides of a communications link become out of sync are provided. In response to receiving a packet with an expected sequence count from a receiving device, a transmitting device may adjust pointers into a transmit buffer allowing the transmitting device to begin transmitting packets with the sequence count expected by the receiving device.
