Abstract

In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for traffic aggregation on multiple Wide Area Network (WAN) backhauls and multiple distinct Local Area Network (LAN) networks; for traffic load balancing on multiple WAN backhauls and multiple distinct LAN networks; and for performing self-healing operations utilizing multiple WAN backhauls serving multiple distinct LAN networks. For example, in one embodiment, a first Local Area Network LAN access device is to establish a first LAN; a second LAN access device is to establish a second LAN; a first Wide Area Network WAN backhaul connection is to provide the first LAN access device with WAN connectivity; a second WAN backhaul connection to provide the second LAN access device with WAN connectivity; a management device is communicatively interfaced with each of the first LAN access device, the second LAN access device, the first WAN backhaul connection, and the second WAN backhaul connection; and the management device routes a first portion of traffic originating from the first LAN over the first WAN backhaul connection and routes a second portion of the traffic originating from the first LAN over the second WAN backhaul connection.

First claim

The invention claimed is:

1. A network manager comprising:
a first interface that couples to a first local area network (“LAN”) access device;
a second interface that physically couples to a first wide area network (“WAN”) backhaul; and
a third interface that wirelessly couples to a second WAN backhaul, the second WAN backhaul being operationally distinct from the first WAN backhaul, the network manager load-balancing traffic from the first LAN access device such that a first portion of traffic from the first LAN access device is directed to the first WAN backhaul at a higher transfer rate than a second portion of traffic that is directed from the first LAN access device to the second WAN backhaul.

2. The network manager of claim 1 wherein the first interface, the second interface and the third interface comprise at least one interface type selected from a group consisting of logical, wireless, wired, software, or hardware interfaces.

3. The network manager of claim 1 further comprising a fourth interface that couples to a second LAN access device wherein the fourth interface comprise at least one interface type selected from a group consisting of logical, wireless, wired, software, or hardware interfaces.

4. The network manager of claim 3 wherein the first LAN access device is in a first LAN and the second LAN access device is in a second LAN.

5. The network manager of claim 4 wherein the first LAN and the second LAN are operationally distinct.

6. The network manager of claim 3 wherein the first LAN access device and the second LAN access device are connected.

7. The network manager of claim 3 wherein the first LAN access device and the second LAN access device are in the first LAN.

8. The network manager of claim 1 wherein the network manager is a hardware or software component within the first LAN access device.

9. The network manager of claim 1 wherein the first LAN access device is selected from the group of access devices consisting of:
an access point;
a wireless LAN access point;
a modem;
a router;
a gateway;
a Digital Subscriber Line (DSL) Customer Premises Equipment (CPE) modem or gateway;

a G.hn compatible device;
a HomePlug device;
a Home Phoneline Network Alliance (HPNA) based device;
an in-home coax distribution device;
an in-home power line device;
an in-home metering communication device;
an in-home appliance interfaced with the LAN;
a set-top box (STB)/set-top unit (STU) customer electronics device;
a cellular base station;
a wireless femtocell base station;
a wireless compatible base station;
a wireless mobile device repeater;

a network connection capable television;
a network connection capable media player;
a network connection capable gaming console;
a network connection capable audio device;
a network connection capable streaming device;
a smartphone;
a personal computer;
a laptop computer;
a tablet computing device;
a computing device connected to the LAN;
a network attached storage device; and
an autonomous device.

10. The network manager of claim 1 wherein the network manager directs traffic from the first LAN access device to the first WAN backhaul when there is a failure condition in the second WAN backhaul.

11. The network manager of claim 4 wherein the network manager directs traffic from the first LAN access device to the first WAN backhaul when there is a failure condition in one or more of the second WAN backhaul, the second LAN, and or the second LAN access device.

12. A network manager comprising:
a first interface that couples to a first local area network (“LAN”) device;
a second interface that physically couples to a first wide area network (“WAN”) backhaul; and
a third interface that wirelessly couples to a second WAN backhaul, the network manager load-balancing traffic from the first LAN access device such that a first portion of traffic from the first LAN access device is directed to the first WAN backhaul at a higher transfer rate than a second portion of traffic that is directed from the first LAN access device to the second WAN backhaul.

13. The network manager of claim 12 wherein the first interface, the second interface and the third interface comprise at least one interface type selected from a group consisting of logical, wireless, wired, software, or hardware interfaces.

14. The network manager of claim 12 further comprising a fourth interface that couples to a second LAN device wherein the second LAN device couples to a second LAN.

15. The network manager of claim 12 wherein the network manager is a hardware or software component within the first LAN device.

16. The network manager of claim 12 wherein the first LAN device is selected from a group of devices consisting of:

17. A method for load-balancing traffic from at least one local area network (LAN) across a plurality of wide area network (WAN) backhauls, the method comprising:
receiving traffic from a first LAN; and
directing a first portion of received traffic from the first LAN to a first WAN backhaul at a first transfer rate; and directing a second portion of the received traffic from the first LAN to a second WAN backhaul at a second transfer rate that is lower than the first transfer rate, the second WAN backhaul being operationally distinct from the first WAN backhaul.

18. The method of claim 17 wherein the steps of directing the first portion of the received traffic and directing the second portion of the received traffic are performed within a first LAN access device.

19. The method of claim 17 wherein the steps of directing the first portion of the received traffic and directing the second portion of the received traffic is performed within a first LAN device.

20. The method of claim 17 wherein the first portion of traffic is directed to the first WAN backhaul at a rate that is less than a potential maximum transfer rate of the connection between the first LAN and the first WAN backhaul.

21. The method of claim 17 wherein traffic from the first LAN is directed entirely to the first WAN backhaul when there is a failure condition in the second WAN backhaul.
