The present invention provides a protocol and associated method for enhancing the throughput and response time performance of Transmission Control Protocol/Internet Protocol (TCP/IP) applications and services in Internet and Intranet environments that use the TCP/IP protocol suite, e.g., HTTP Internet browsers, HTTP servers, FTP servers, etc. The protocol of the present invention, termed Communication Enhancement Protocol (CEP), comprises a flow control method that functions to maximize the performance of IP communication links. The CEP is positioned in either Transport Layer 4 or Session Layer 5 of the OSI communications protocol stack. The CEP of the present invention optimizes the interactions between transport protocols and applications by utilizing novel flow control algorithms so as to reduce overhead and the use of the server's resources. Using the CEP of the present invention, data throughput and response time up to 2.5 times as fast as compared with conventional communication protocols. The CEP also comprises an error handling mechanism that permits detection of and recovery from packet loss and extreme network congestion.

[ What is claimed is:] [7.]7. In a data communication system having a client and a server side, a method of forming a shutdown message to be sent over a communication channel formed between said client and said server, comprising the steps of:including an Internet Protocol (IP) header field within said shutdown message;including User Datagram Protocol (UDP) header field within said shutdown message;including a message type field within said shutdown message indicating the type of said message;including a last received message number field within said shutdown message indicating the number of the last received message;including a data field within said shutdown message containing data;generating said shutdown message by combining together the bits representing said IP header field, said UDP header field, said message type field, said last received message number field and said data field; andwherein said shutdown message is part of a transport mechanism positioned between Transport Layer 4 or Session Layer 5 of the Open System Interconnet (OSI) stack.
