Abstract

Dynamic sizing of packets of data is disclosed. In one embodiment, a system includes a client and a server. The client receives packets of dynamic size, the client having a bandwidth. The server determines the dynamic size of the packets based on at least one factor. One such factor is the bandwidth of the client. The server sends the packets to the client.

Claims

1. A system comprising:

a client to receive packets of dynamic size, the client having a bandwidth; and

,

a server to determine the dynamic size of the packets based on at least one factor including the bandwidth of the client and to send the packets to the client.

2. The system of claim 1, wherein the server comprises a codec having a data frame size.

3. The system of claim 2, wherein the at least one factor further includes the data frame size of the codec.

4. The system of claim 1, wherein the at least one factor further includes video receive capabilities of the client.

5. The system of claim 1, wherein the at least one factor further includes video transmit capabilities of the server.

6. The system of claim 1, wherein the bandwidth of the client comprises an assumed bandwidth.

7. The system of claim 1, wherein the bandwidth of the client comprises an actual bandwidth.

8. The system of claim 1, wherein the bandwidth of the client is selected from the group essentially consisting of:

a modem bandwidth of 14,400 bits per second (bps);

a modem bandwidth of 28,800 bps;

a local-area network (LAN) bandwidth; and

, an Integrated Services Digital Network (ISDN) bandwidth.

9. The system of claim 1, further comprising a local-area network (LAN) coupling the client with the server.

10. The system of claim 1, wherein the client further comprises a modem to couple the client over the Internet with the server.

11. The system of claim 1, wherein the client further comprises an Integrated Services Digital Network (TSDN) connection to couple the client over the Internet with the server.

12. A system comprising:

a client to receive packets of dynamic size, the client having a bandwidth selected from the group essentially consisting of;

a modem bandwidth of 14,400 bits per second (bps), a modem bandwidth of 28,800 bps, a local-area network (LAN) bandwidth, and, an Integrated Services Digital Network (ISDN) bandwidth; and

,

a server to send the packets to the client and to determine the dynamic size of the packets based on at least one factor including;

the bandwidth of the client, a data frame size of a codec of the server, video receive capabilities of the client and, video transmit capabilities of the server.

13. The system of claim 12, wherein the bandwidth of the client is selected from the group essentially consisting of:

an assumed bandwidth and an actual bandwidth.

14. A method comprising:

determining a bandwidth of a client; and

,

determining a dynamic size of packets to be sent to the client based on at least one factor including the bandwidth of the client.

15. The method of claim 14, further comprising sending the packets of the dynamic size to the client.

16. The method of claim 14, wherein determining the bandwidth of the client comprises selecting an assumed bandwidth of the client.

17. The method of claim 14, wherein determining the bandwidth of the client comprises determining an actual bandwidth of the client.

18. The method of claim 14, wherein determining the dynamic size of the packets comprises:

determining whether video transmit capabilities are used; and

,

upon determining that video transmit capabilities are unused, selecting the dynamic size of the packets based on the bandwidth of the client.

19. The method of claim 18, wherein determining the dynamic size of the packets further comprises changing the dynamic size of the packets to be an integral number of a frame size of a codec.

20. The method of claim 18, wherein determining the dynamic size of the packets further comprises upon determining that video transmit capabilities are used:

determining whether the client is part of a local-area network (LAN); and

,

upon determining that the client is apart of the LAN, selecting the dynamic size of the packets based on a predetermined low bandwidth.

21. The method of claim 20, wherein determining the dynamic size of the packets further comprises changing the dynamic size of the packets to be an integral number of a frame size of a codec.

22. The method of claim 20, wherein the predetermined low bandwidth is based on a modem bandwidth of 14,400 bits per second.

23. The method of claim 20, wherein determining the dynamic size of the packets further comprises upon determining that the client is part of the LAN:

determining whether the client has suitable video receive capabilities;

upon determining that the client has suitable video receive capabilities, selecting the dynamic size of the packets based on a predetermined high bandwidth; and

,

upon determining that the client has unsuitable video receive capabilities, selecting the dynamic size of the packets based on the predetermined low bandwidth.

24. The method of claim 23, wherein determining the dynamic size of the packets further comprises changing the dynamic size of the packets to be an integral number of a frame size of a codec.

25. The method of claim 23, wherein the predetermined high bandwidth is based on a LAN bandwidth.

26. The method of claim 14, wherein the bandwidth of the client is selected from the group essentially consisting of:

a modem bandwidth of 14,400 bits per second;

a modem bandwidth of 28,800 bps;

a local-area network (LAN) bandwidth; and

, an Integrated Services Digital Network (ISDN) bandwidth.

27. A computer comprising:

a processor;

a computer-readable medium; and

,

a computer program executed by the processor from the medium to determine a dynamic size of packets to be sent to a client based on at least one factor including the bandwidth of the client.

28. The computer of claim 27, wherein the at least one factor includes at least one of the group essentially consisting of:

a data frame size of a codec, video transmit capabilities, and, video receive capabilities of the client.

29. A computer-readable medium having a computer program stored thereon for execution on a computer to determine a dynamic size of packets to be sent to a client based on at least one factor including the bandwidth of the client.

30. The medium of claim 29, wherein the at least one factor includes at least one of the group essentially consisting of:

a data frame size of a codec, video transmit capabilities, and, video receive capabilities of the client.
