2013-04-18 Thread vmonmoonshine
Hello Zack, In testing the retransmission algorithm, I encounter situations that the ack/retransmission algorithm is unable to resolve by design. It happens when the header of a packet gets deliver but the middle part gets dropped. For example in the following scenario Server sends packet 1 len 4
