Abstract
A client/server and similar system, such as in a TCP/IP or internet or intranet environment, in which CRC encoded tokens are used for synchronization of connectionless applications between the server and client across a network. CRC algorithms are used to hash compress a sequence of bytes which can represent a screen, or panel, or a particular state of a server machine. Responsive to a first request from a client received at a first port, a server establishes a session in listening mode on a second port; generates, stores and returns to the client a session token including a client token and panel token, and closes the first port. Responsive to a second request from a client received at the second port, the server verifies that the second request includes a session token identical to a stored session token indexed by said second port, and if so, executes said second request. The session token, including the client token and panel token, is generated by CRC hashing client and panel indicia, respectively.
