Abstract

In accordance with an embodiment of the present invention, a method and apparatus for maximizing packet throughput on a network is disclosed. The apparatus comprises means for computing an average packet size for incoming packets. The average packet size can be dynamically changed. The apparatus also comprises means for adjusting an amount of data to be transmitted per unit of time based on the average packet size. The amount of data to be transmitted per unit of time can also be dynamically adjusted. The amount of data to be transmitted per unit of time can be based on both a processing speed of an access point and the average packet size.

Claims

1. A method of maximizing a packet transfer rate in a network from a network appliance to a access point, wherein the network appliance has a faster packet transfer rate than the access point, the method comprising the steps of:

a. determining a transfer speed of packets for the access point; and

b. controlling a rate of transfer of packets from the network appliance to accommodate the access point

c. determining an average size of packets received by the network appliance for transfer to the access point; and

d. adjusting the rate of transfer of packets from the network appliance in response to the average size of packets.

2. The method according to claim 1 wherein the step of determining a transfer speed of packets for the access point comprises measuring the transfer speed.

3. The method according to claim 1 wherein the step of determining a transfer speed of packets for the access point comprises a table containing data for a plurality of commercially available access points.

4. The method according to claim 1 wherein the step of adjusting the rate of transfer is performed dynamically to accommodate changes in the average rate of transfer of packets.

5. An apparatus for maximizing a packet transfer rate in a network from a network appliance to a access point, wherein the network appliance has a faster packet transfer rate than the access point, the method comprising the steps of:

a. a system for determining a transfer speed of packets for the access point; and

b. a controller for controlling a rate of transfer of packets from the network appliance to accommodate the access point

c. a circuit for determining an average size of packets received by the network appliance for transfer to the access point; and

d. controller means for adjusting the rate of transfer of packets from the network appliance in response to the average size of packets.

6. The apparatus according to claim 5 wherein the system for determining a transfer speed of packets for the access point comprises a circuit measuring the transfer speed.

7. The apparatus according to claim 5 wherein the system of determining a transfer speed of packets for the access point comprises a table containing data for a plurality of commercially available access points.

8. The apparatus according to claim 5 wherein the controller means operates dynamically to accommodate changes in the average rate of transfer of packets.

9. A method of maximizing packet throughput on a network, comprising:

a. computing an average packet size; and

b. adjusting an amount of data to be transmitted per unit of time based on the average packet size.

10. The method of claim 9 wherein the amount of data to be transmitted per unit of time is dynamically adjusted.

11. The method of claim 9 wherein the data is transmitted to a wireless device selected form the group consisting of a PDA, wireless e-mail device, a wireless laptop, a wireless printer via an access point.

12. The method of claim 9 wherein the amount of data to be transmitted per unit of time is based on a processing speed of an access point.

13. An apparatus for maximizing packet throughput on a network, comprising:

a. means for computing an average packet size; and

b. means for adjusting an amount of data to be transmitted per unit of time based on the average packet size.

14. The apparatus of claim 13 wherein the amount of data to be transmitted per unit of time is dynamically adjusted.
