Abstract

A system and method of automatically transforming instant message transmission modes on the Internet is disclosed. The transformation system is applied to a Java-based instant messenger and could be automatically transformed to four transmission modes in accordance with different network environments. The four transmission modes include the socket mode (i.e. direct connection through socket), HTTP 1.1 mode (i.e. connection through a proxy server and a firewall that both support HTTP 1.1), HTTP 1.0 mode (i.e. connection through a proxy server and a firewall that both support HTTP 1.0) and a pure-HTML mode (i.e. without JAVA applet).

Claims

1. A system of automatic transforming instant message transmission modes on Internet, said system comprises:

at least two clients, wherein said client includes a computer system, said computer system comprises a web browser, a first packet-processing program, a network configuration processing program for detecting and identifying a network auto-configuration, a proxy configuration processing program for detecting and identifying a proxy configuration, a connection time-out program, and a Java applet identification program for determining if said client be allowable of downloading and installing a Java applet, and said web browser includes a network auto-configuration and a proxy configuration; and

a server, wherein said server comprises a second packet-processing program for processing a plurality of transmitting packets between said server and said client, a conference management program for opening or closing a network conference and for managing the login and logout of said client, a message broadcast program for transmitting at least a message to said client and for broadcasting said messages to a plurality of clients participating in said network conference, a mode 1 processing program for processing network connection mechanism of the mode 1 and decoding a plurality of packets of the mode 1, a mode 2 processing program for processing network connection mechanism of the mode 2 and decoding a plurality of packets of the mode 2, a mode 3 processing program for processing network connection mechanism of the mode 3 and decoding a plurality of packets of the mode 3, and a mode 4 processing program for processing network connection mechanism of the mode 4 and decoding a plurality of packets of the mode 4;

wherein said mode 1 means a connection that the client connects to the server directly through any allowable socket, said mode 2 means a connection that the client connects to the server across proxy servers and firewalls supporting persistent HTTP 1.1 connection, said mode 3 means a connection that the client connects to the server across proxy servers and firewalls supporting non-persistent HTTP 1.0 connection, and said mode 4 means a connection that a web-based instant interactive message application is applied.

2. The system of claim 1, wherein said client further comprises a proxy server and a firewall for blocking the network connections unallowable of said clients.

3. The system of claim 1, wherein said computer system further comprises a Java run-time environment when the transmission mode is set to said mode 1, said mode 2 or said mode 3, and no plug-in or Java run-time is required when the transmission mode is set to mode 4.

4. The system of claim 2, wherein said proxy server supports HTTP 1.1 or HTTP 1.0 protocol and said firewall supports HTTP 1.1 or HTTP 1.0 protocol.

5. The system of claim 1, wherein said plurality of transmitting packets between said server and said clients are HTTP packets or socket packets.

6. The system of claim 1, wherein said first packet-processing program and said second packet-processing program both are multi-threading Java applications and temporary store the received plurality of transmitting packets between said server and said clients.

7. The system of claim 1, wherein said network configuration processing program is used to identify if said network auto-configuration is assignable and said proxy configuration processing program is used to identify if said proxy configuration is assignable.

8. The system of claim 1, wherein said connection time-out program is used to detect a response time as said client trying to login said server and to identify the numbers of time-out as said client trying to login said server.

9. A method of automatic transforming instant message transmission modes on Internet, said method comprises:

processing a plurality of transmitting packets between a server and at least two clients according to a first packet-processing program and a second packet-processing program, wherein each said clients comprise a computer system, said computer system comprises a web browser, said first packet-processing program, a network configuration processing program, a proxy configuration processing program, a connection time-out program, and a Java applet identification program, wherein said web browser comprises a network auto-configuration and a proxy configuration, and said server comprises said second packet-processing program, a conference management program, a message broadcast program, a mode 1 processing program, a mode 2 processing program, a mode 3 processing program and a mode 4 processing program;

identifying if a Java applet downloadable at said clients;

detecting said network auto-configuration and identifying whether said network auto-configuration is assignable by said network configuration processing program when said Java applet is downloadable at said clients; and

detecting said proxy configuration and identifying whether said proxy configuration is assignable by said proxy configuration processing program when said network auto-configuration is not assignable at said clients;

wherein said mode 1 means a connection that the client connects to the server directly through any allowable socket, said mode 2 means a connection that the client connects to the server across proxy servers and firewalls supporting persistent HTTP 1.1 connection, said mode 3 means a connection that the client connects to the server across proxy servers and firewalls supporting non-persistent HTTP 1.0 connection, and said mode 4 means a connection that a web-based instant interactive message application is applied.

10. The method of claim 9, wherein said mode 4 processing program set the transmission mode to said mode 4 when said Java applet is not downloadable.

11. The method of claim 9 further comprises setting the transmission mode to said mode 2 when said network auto-configuration and said proxy configuration are assignable and setting the transmission mode to the mode 1 when said proxy configuration is not assignable.

12. The method of claim 11 further comprises building up a socket connection and detecting a response time of said socket connection in accordance with said connection time-out program to set the transmission mode to said mode 1 when said response time is less than a pre-defined time, wherein said connection time-out program further detects number of time-out of said socket connection when said response time exceeds said pre-defined time.

13. The method of claim 12 further comprises setting the transmission mode to said mode 2 when said number of time-out exceeds a pre-defined number and detecting said response time of said socket connection by said connection time-out program when said number of time-out is less than a pre-defined number.
