Abstract

A system and method for detecting computer port inactivity are disclosed. In one embodiment, a system includes a router that has a first interface to communicate with a first connection at an end-user computer and a second interface to communicate with a second connection at a distributed computer network. The system includes detection logic responsive to the first interface to detect inactivity at the end-user computer and further includes blocking logic responsive to the detection logic. The blocking logic is operable to selectively initiate a blocking signal to disable communicating data received at the second interface to the end-user computer via the first interface. The detection logic and the blocking logic are embedded within a port of the router.

Claims

1. A system comprising:

a router, including;

a first interface to communicate with a first connection at an end-user computer;

a second interface to communicate with a second connection at a distributed computer network;

detection logic responsive to the first interface to detect inactivity at the end-user computer; and

blocking logic responsive to the detection logic, the blocking logic to selectively initiate a blocking signal to disable communicating data received at the second interface to the end-user computer via the first interface,

wherein the detection logic and the blocking logic are embedded within a port of the router.

2. The system of claim 1, wherein the port is an auto-sensing port.

3. The system of claim 1, wherein the port is an Ethernet port.

4. The system of claim 1, wherein the first connection is a local area network connection.

5. The system of claim 4, wherein the blocking logic is adapted to disable communications received at the second interface from being sent over the first interface.

6. The system of claim 5, wherein the blocking logic is further adapted to allow communications to be sent over the first interface to at least one other end-user computer in the local area network.

7. The system of claim 1, wherein the detection logic is adapted to detect user inactivity at the end-user computer.

8. The system of claim 1, wherein the second connection is a wide area network connection.

9. A method comprising:

detecting that an end-user computer coupled to routing equipment has been idle for an idle time greater than an idle time inactivity threshold and determining an inactivity event at the routing equipment; and

initiating a blocking signal to block data received at the routing equipment via a wide area network data connection from being communicated from the routing equipment to the end-user computer via the first local data connection;

wherein the detecting and the initiating the blocking signal are performed by logic that is embedded within a port of the routing equipment.

10. The method of claim 9, wherein the port is an auto-sensing port.

11. The method of claim 9, wherein the port is an Ethernet port.

12. The method of claim 9, further comprising establishing a connection at the routing equipment, the connection including a first local data connection between the end-user computer and the routing equipment.

13. The method of claim 12, wherein the connection further includes the wide area network data connection between the routing equipment and an internet service provider.

14. The method of claim 12, wherein the connection includes a digital subscriber line connection between the end-user computer and an internet service provider.

15. The method of claim 9, wherein the routing equipment is a digital subscriber line routing equipment.

16. A method comprising:

establishing a first portion of a connection at routing equipment, the first portion of the connection including a local data connection between an end-user computer and the routing equipment, the first portion of the connection terminating at a first port of the routing equipment,

establishing a second portion of the connection, the second portion of the connection including a wide area data connection between the routing equipment and internet service provider equipment, the second portion of the connection terminating at a second port of the routing equipment;

detecting at the first port of the routing equipment an indication that the end-user computer has been idle for an idle time greater than an idle time inactivity threshold; and

during a first period of time, initiating a blocking signal at routing equipment, the blocking signal blocking data received from the second port of the routing equipment from being communicated via the first port of the routing equipment;

wherein detection logic and blocking logic are embedded within a port of the routing equipment.

17. The method of claim 16, wherein the port is an auto-sensing port.

18. The method of claim 16, wherein the port is an Ethernet port.

19. The method of claim 16, wherein the connection is a digital subscriber line connection.

20. The method of claim 16, further comprising, during a second period of time after the first period of time:

detecting activity at the first port of the routing equipment indicating activity at the end-user computer; and

communicating data received at the second port of the routing equipment to the first port of the routing equipment and to the end-user computer.
