Abstract

A receiver of network data dynamically filters packets by packet type from a network device CPU based on usage information, such as time, day, location, and feature (e.g., “video” or “application”) selection.

Claims

1. A method comprising:

receiving dynamic usage information pertaining to a network device, wherein the usage information is established by at least one of time of day, day of the week, location of the network device;

based on the dynamic usage information, determining at least one desired packet type from a network; and

passing, from a packet receiver of the network device to a central processing unit (CPU) of the network device, only the packets determined to be desired, wherein if the user selects a “

video”

feature, the desired packet type includes video packets but not binary application packets, wherein if the user changes to an “

application”

feature selection, the desired packet type includes binary application packets but not video packets.

2. The method of claim 1, wherein the usage information includes time of day.

3. The method of claim 1, wherein the usage information includes day of the week.

4. The method of claim 1, wherein the usage information includes location of the network device.

5. The method of claim 1, wherein the usage information includes user preference as indicated by input received from a user input device.

6. The method of claim 5, wherein the user preference is a “

video”

feature or an “

application”

feature of the network device.

7. The method of claim 1, wherein at least a first packet type is always passed to the CPU regardless of the usage information.

8. The method of claim 1, wherein the CPU executes the receiving and determining acts.

9. The method of claim 1, wherein the packet receiver executes the receiving and determining acts.
