Abstract:
1. A method for reliably transmitting over a computer network requests, from client applications running on a client computer to server-applications running on a server computer, the client computer having a central processing unit, memory, a client-side application protocol stack, a plurality of client-side functions to perform reliable transport-related tasks for a plurality of applications, including a function that returns a starting sequence number and range of allowable sequence numbers for request messages, and a client-side transport protocol stack, the method comprising: the client-side application protocol stack the client-side transport protocol stack receiving the request message and transmitting it to a server-side transport protocol stack; the client-side application protocol stack retransmitting the request message if a message is not received from the server-side transport protocol stack which contains the sequence number of the request message and a type code that indicates before the time-out period for i-th transmission has elapsed since the request message was transmitted for the i-th time and the number of times that the request message has been transmitted is less than a total allowed number of transmissions; and wherein if a message received by the client-side application protocol stack from the server-side transport protocol stack contains the sequence number of the request message and a type code that indicates that it is a provisional reply message to the request message, then the current time-out period for retransmission is modified to delay its expiration.
