Abstract

In one embodiment, the systems and methods determine an initial bandwidth at a client device; allocate an allocated bandwidth to the client device between a first server and a second server; monitor the allocated bandwidth; and adjust the allocated bandwidth based on a target bandwidth from the first server to the client.

Claims

1. A method comprising:

determining an initial bandwidth at a client device;

allocating an allocated bandwidth to the client device between a first server and a second server;

monitoring the allocated bandwidth; and

adjusting the allocated bandwidth based on a target bandwidth from the first server to the client.

2. The method according to claim 1 wherein the first server transmits data related to a collaboration session.

3. The method according to claim 1 wherein the first server transmits voice data related to a collaboration session.

4. The method according to claim 1 wherein the client device is configured to participant in a collaboration session.

5. The method according to claim 1 wherein the target bandwidth corresponds with transmission of audio content.

6. The method according to claim 1 wherein the target bandwidth corresponds with transmission of video content.

7. The method according to claim 1 wherein the second server transmits data related to a collaboration session.

8. The method according to claim 1 wherein the second server transmits voice data related to a collaboration session.

9. The method according to claim 1 further comprising calculating the allocated bandwidth based on the initial bandwidth.

10. The method according to claim 9 further comprising calculating the allocated bandwidth based on CBW=IBW−

C wherein CBW represents the allocated bandwidth, IBW represents the initial bandwidth, and C represents the target bandwidth.

11. The method according to claim 1 wherein determining the initial bandwidth further comprises measuring a throughput of data at the client device.

12. The method according to claim 1 wherein the initial bandwidth depends on a connection type associated with the client device.

13. The method according to claim 12 wherein the connection type includes one of a DSL connection, a telephone connection, a WiFi connection, and a T1 connection.

14. The method according to claim 1 wherein the adjusting is based on VBV C−

VCR wherein VBV represents a VoIP bandwidth variant, VCR represents a VoIP bandwidth receiving rate and bandwidth detecting data, and C represents the target bandwidth.

15. The method according to claim 1 wherein the adjusting further comprises increasing the allocated bandwidth to the between the client device and the first server.

16. The method according to claim 1 wherein the adjusting further comprises decreasing the allocated bandwidth to the between the client device and the first server.

17. A system, comprising:

a bandwidth allocation module configured to assign an allocated bandwidth between a client device and a first server and a second server;

a bandwidth detection module configured to detect an initial bandwidth available to the client device and configured to monitor the allocated bandwidth; and

a collaboration session detection module configured to detect a collaboration session.

18. The system according to claim 17 wherein the client device is configured to participate in the collaboration session.

19. The system according to claim 17 further comprising a storage module configured to store content shared during the collaboration session.
