METHOD FOR TRANSMITTING MULTIMEDIA DATA ASSOCIATED WITH MULTIMEDIA APPLICATION, DATA TRANSMITTING METHOD, SYSTEM FOR TRANSMITTING MULTIMEDIA DATA INTO DISTRIBUTED NETWORK, AND COMMUNICATION PROTOCOL FOR ENABLING MULTIMEDIA COMMUNICATION BETWEEN COMPUTERS

摘要

PROBLEM TO BE SOLVED: To provide a device and method for tunneling a media streaming application through a firewall.;SOLUTION: When transmitting multimedia data associated with a multimedia application, a TCP/IP connection is established between a client application and a server application. UDP data are intercepted at an application level from one or more UDP data ports and channeled into one or more tunneling TCP data connections. TCP data are intercepted at the application level from one or more TCP data ports and re-directed to a tunneling TCP port. The channeled UDP data are received and dispatched to one or more local UDP data ports. Re-directed TCP data are received and then further re-directed to one or more local TCP data ports.;COPYRIGHT: (C)2007,JPO&INPIT
