Abstract

A system and method for aggregating and fragmenting packets is described. Data packets containing voice data and other data that suffer significantly in quality when delayed may be aggregated together and fragmented. The aggregation and fragmentation permits networks to push these time-sensitive packets more easily through a network based on priority given to fragmented data.

Claims

1. A method for handling communications in an access point comprising the steps of:

receiving original data packets at said access point, the original data packets including a first data packet having a first header and a first payload and a second data packet having a second header and a second payload;

aggregating in said access point said original data packets into an aggregated data packet, said aggregated data packet including an aggregated data packet header and an aggregated data packet payload where the aggregated data packet payload includes at least said first payload and said second header and said second payload;

fragmenting in said access point said aggregated data packet into fragmented data packets; and

outputting said fragmented data packets via a transceiver of said access point.

2. The method according to claim 1, wherein said original data packets include voice information.

3. The method according to claim 1, wherein said original data packets include time-sensitive data.

4. The method according to claim 1, wherein said aggregating step is performed in an LLC layer of said access point.

5. The method according to claim 1, wherein said fragmenting step occurs in a MAC layer of said access point.

6. The method according to claim 1, wherein said fragmented data packets are capable of being received by a system that recombines said fragmented data packets and extracts said original data packets.

7. The method of claim 1, wherein the step of receiving original data packets includes receiving at least one original data packet from each of a first source address and a second source address, and wherein the step of outputting said fragmented data packets includes transmitting at least one fragmented data packet to each of a first destination address and a second destination address.

8. The method of claim 1, wherein said aggregated data packet header includes said first header.

9. The method of claim 1, wherein said aggregated data packet header is a dummy header and said aggregated data packet payload includes said first header.

10. A non-transitory computer-readable medium having a program stored thereon, said program for handling communications in an access point upon execution in said access point, said program comprising the steps of:

receiving original data packets at said access point, the original data packets including a first data packet having a first header and a first payload and a second data packet having a second header and a second payload;

aggregating in said access point said original data packets into an aggregated data packet, said aggregated data packet including an aggregated data packet header and an aggregated data packet payload where the aggregated data packet payload includes at least said first payload and said second header and said second payload;

fragmenting in said access point said aggregated data packet into fragmented data packets; and

outputting said fragmented data packets via a transceiver of said access point.

11. The non-transitory computer-readable medium according to claim 10, wherein said original data packets include voice information.

12. The non-transitory computer-readable medium according to claim 10, wherein said original data packets include time-sensitive data.

13. The non-transitory computer-readable medium according to claim 10, wherein said aggregating step is performed in an LLC layer in said access point.

14. The non-transitory computer-readable medium according to claim 10, wherein said fragmenting step occurs in a MAC layer in said access point.

15. The non-transitory computer-readable medium according to claim 10, wherein said fragmented data packets are capable of being received by a system that recombines said fragmented data packets and extracts said original data packets.

16. The non-transitory computer-readable medium according to claim 10, wherein said aggregated data packet header includes said first header.

17. The non-transitory computer-readable medium according to claim 10, wherein said aggregated data packet header is a dummy header and said aggregated data packet payload includes said first header.

18. A system for handling communications comprising:

an access point with a processor and a transceiver, the processor executing three communication processing layers, the access point being configured to receive original data packets, the original data packets including a first data packet having a first header and a first payload and a second data packet having a second header and a second payload said processor executing the three communication processing layers as;

a first layer that aggregates said original packets into an aggregated data packet, said aggregated data packet including an aggregated data packet header and an aggregated data packet payload where the aggregated data packet payload includes at least said first payload and said second header and said second payload;

a second layer that fragments said aggregated data packet into fragmented data packets; and

a third layer that outputs said fragmented data packets to said transceiver.

19. The system for handling communications according to claim 18, wherein said first layer is a LLC layer.

20. The system for handling communications according to claim 18, wherein said second layer is a MAC layer.

21. The system for handling communications according to claim 18, wherein said third layer is a physical layer.

22. The system according to claim 18, wherein said aggregated data packet header includes said first header.

23. The system according to claim 18, wherein said aggregated data packet header is a dummy header and said aggregated data packet payload includes said first header.
