Abstract

Methods and apparatuses enabling secure multi-link point to point protocol over connected heterogeneous single path access networks are described. In one embodiment, a method of an access device includes associating the access device with a single-path network and at least one other network, and accessing a data of a service provider through an aggregation server connected to the single-path network and the other network. In one embodiment, the aggregation server transfers the data to the access device at a combined throughput speed of the single-path network and the at least one other network. The method may include maintaining a connection between the access device and the aggregation server even when any one or more of the single-path network and the at least one other network disconnect.

Claims

1. A method of an access device, comprising;

associating the access device with a single-path network and at least one other network; and

accessing a data of a service provider through an aggregation server connected to the single-path network and the other network, and enabling to transfer the data between the aggregation-server and the access device at a combined throughput speed of the single-path network and the at least one other network.

2. The method of claim 1, further comprising maintaining a connection between the access device and the aggregation server even when any one or more of the single-path network and the at least one other network disconnect.

3. The method of claim 2, wherein the at least one other network to communicate at least some of the data through a layer 2 tunnel enabled through a proxy device within the at least one other network.

4. The method of claim 3, wherein the proxy device is also co-located within the access device.

5. The method of claim 1, further comprising encrypting the data across the single-path network but not across any of the at least one other network.

6. The method of claim 5, wherein the encrypting the data is performed selectively only during a given time interval.

7. The method of claim 1, wherein the single-path network comprises one of an Ethernet network, a digital subscriber line network, a cable network, a leased-line/dial-up network, and wireless access network.

8. The method of claim 1, wherein the aggregation server is a single point of connectivity between the single-path network and the at least one other network and a back-bone network.

9. The method of claim 8, wherein the service provider is accessed through the back-bone network.

10. The method of claim 1, wherein the associating the access device with a single-path network and the at least one other network is formed through at least one point to point (PPP) negotiation between the access device and the aggregation-server.

11. The method of claim 10, wherein the aggregation server and the access-device form a multi-link point-to-point (MLPPP) connection of the single-path network and the at least one other network to form the combined throughput speed.

12. The method of claim 11, further comprising continuing the MLPPP connection when any one or more of the single-path network and the at least one other network is disabled.

13. A system, comprising:

a back-bone network;

an aggregation server connected to the back-bone network to enable a secure multi-link point to point connection over heterogeneous single path access networks;

a first single path network having a first access method and a second single path network having another access method connected to the aggregation server to form an aggregated connection;

an access device associated with the first single path network and the second single path network; and

a proxy device in the first single path network to transport the layer-2 session between the access-device and aggregation-server, when the first single-path access network does not provide direct layer-2 connectivity.

14. The system of claim 13, wherein a MLPPP connection between the access device and the aggregation server is maintained even when any one of the first single path network and the second signal path network is no longer associated with the access device.

15. The system of claim 14, further comprising a proxy device of the first single path network to communicate at least some of the data through a layer 2 tunnel when the single path network does not provide a direct layer-2 connectivity.

16. The system of claim 15, wherein at least one of the access device, the aggregation server, and the proxy device to encrypt a data transmitted either of the first single path network and the second signal path network based upon at least one of time dependant rules and other administrative policies to form the secure multi-link point to point connection.

17. The system of claim 13, wherein the secure multi-link point to point connection to aggregate throughput of the first single path network and the second signal path network.

18. The system of claim 17, wherein the first single path network having the first access method is an Ethernet network and the second single path network having the another access method is a wireless local area network.

19. A machine-accessible medium that provides instructions that, if executed by a processor, will cause the processor to perform operations of an aggregation server, comprising:

receiving a data through a back-bone network from a service provider;

aggregating bandwidth of a first single path network and a second single path network, both of which are connected to an access device;

encrypting and decrypting at least some of the data based upon time sensitive and single-channel network dependent encryption algorithms of the aggregation server; and

transmitting the data to the access device based upon the time sensitive and single-channel network dependent encryption algorithms through a speed of the aggregated bandwidth.

20. The machine-accessible medium of claim 19, further comprising tunneling at least a portion of the data between the access device and the aggregation server using a layer 2 tunnel, when one or more of the single path networks do not provide a direct layer-2 connectivity.
