METHOD FOR TUNNELING DATA ASSOCIATED WITH PACKET-BASED MULTIMEDIA COMMUNICATIONS STANDARD, METHOD FOR COMMUNICATINGS PORT TRAFFIC VIA SINGLE HTTP PORT, COMPUTER-READABLE MEDIUM WITH PROGRAM INSTRUCTION FOR TUNNELING DATA ASSOCIATED WITH THE PACKET BASED MULTIMEDIA COMMUNICATION STANDARD, COMPUTER-READABLE MEDIUM WITH PROGRAM INSTRUCTION FOR COMMUNICATING WITH PORT TRAFFIC VIA SINGLE HTTP PORT, AND SYSTEM FOR TUNNELING PORT TRAFFIC ADDRESSED TO MULTIPLE PORTS VIA SINGLE PORT

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for tunneling data, using a single pseudo-stateful TCP connection.;SOLUTION: The method and system for tunneling data associated with a packet based multimedia communications standard are provided. The method includes intercepting a library call associated with the multimedia communications standard in a modified TCP/IP stack and registering identification data associated with the library call. A modified TCP/IP header is appended over a pre-existing header of a data packet that is related to the identification data. The method also provides for transmitting the data packet, having the TCP/IP header via a firewall. The TCP/IP header includes a TCP SEQ number and a TCP ACK number for providing a stateful connection.;COPYRIGHT: (C)2006,JPO&NCIPI
