Abstract

In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for traffic aggregation on multiple WAN backhauls and multiple distinct 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 is to provide the second LAN access device with WAN connectivity; and a traffic aggregation unit is to form a logically bonded WAN interface over the first WAN backhaul and the second WAN backhaul. In some embodiments an optional traffic de-aggregation unit may be used.

First claim

What is claimed is:

1. A gateway agent that aggregates bandwidth across a plurality of backhaul connections, the agent comprising:
a transmission control protocol (“TCP”) interface coupled to receive TCP traffic from a first client;
a traffic controller coupled to receive the TCP traffic, the traffic controller converts the TCP traffic to a digital line subscriber (“DSL”) traffic portion and a cellular traffic portion;
a DSL interface coupled to receive the DSL traffic portion, the DSL interface transmits the DSL traffic portion onto a DSL backhaul;
a cellular interface coupled to receive the cellular traffic portion, the cellular interface transmits the cellular traffic portion onto a cellular backhaul; and
a management device coupled to the traffic controller, the management device receives a first link status measurement associated with the DSL backhaul and a second link status measurement associated with the cellular backhaul, the management device determines a transmission path on at least one of the DSL interface and the cellular interface based on the first and second link status measurements.

2. The gateway agent of claim 1 wherein the management device adapts the conversion of the TCP traffic to the DSL traffic portion and cellular traffic portion based on real time link status measurements.

3. The gateway agent of claim 2 wherein real time link status measurements comprises one measurement type selected from a group consisting of bandwidth measurements, delay measurements, capacity measurements, bit rate measurements and link failure measurements.

4. The gateway agent of claim 1 wherein a first size of the DSL traffic portion and a second size of the cellular traffic portion is based on the first link status measurement and the second link status measurement.

5. The gateway agent of claim 1 wherein the traffic controller reorders the DSL traffic portion and the cellular traffic portion based on a first bandwidth associated with the DSL backhaul and a second bandwidth associated with the cellular backhaul.

6. The gateway agent of claim 1 wherein the traffic controller reorders the DSL traffic portion and the cellular traffic portion based on a first delay associated with the DSL backhaul and a second delay associated with the cellular backhaul.

7. The gateway agent of claim 1 wherein the DSL interface and the cellular interface are bonded based on at least one policy within a plurality of user-configurable policies.

8. The gateway agent of claim 7 wherein the user-configurable policies comprises (1) maximizing speed across a combination of the DSL interface and the cellular interface, (2) filling the DSL traffic portion up to a threshold before filing the cellular traffic portion, (3) blocking traffic to a device coupled to the TCP interface, and (4) identifying a set of trusted devices coupled to the TCP interface.

9. The gateway agent of claim 7 wherein the user-configurable policies comprise a failure detection on the DSL backhaul or cellular backhaul.

10. The gateway agent of claim 7 wherein the user-configurable policies comprise an identification of a type of the TCP traffic.

11. The gateway agent of claim 1 wherein the cellular interface is an LTE interface.

12. The gateway agent of claim 1 wherein the gateway agent is integrated within a Wi-Fi access point.

13. The gateway agent of claim 1 wherein the first client is selected from a group consisting of a smartphone, a laptop computer, a desktop computer, a sensor device, a tablet and datacenter.

14. An access gateway agent that aggregates bandwidth across a plurality of backhaul networks, the agent comprising:
a transmission control protocol (“TCP”) interface coupled to communicate TCP traffic between a datacenter a plurality of backhauls;
a traffic controller coupled to receive the TCP traffic, the traffic controller converts the TCP traffic to a digital line subscriber (“DSL”) traffic portion and a cellular traffic portion;
a DSL interface coupled to receive the DSL traffic portion, the DSL interface communicates the DSL traffic portion onto a DSL backhaul;
a cellular interface coupled to receive the cellular traffic portion, the cellular interface communicates the cellular traffic portion onto a cellular backhaul; and
a management device coupled to the traffic controller, the management device performs a first link status measurement associated with the DSL backhaul and a second link status measurement associated with the cellular backhaul, the management device adapts a conversion of the TCP traffic to the DSL traffic portion and the cellular traffic portion based on the first and second congestion measurements.

15. The access gateway agent of claim 14 wherein a first size of the DSL traffic portion and a second size of the cellular traffic portion is based on the first link status measurement and the second link status measurement.

16. The access gateway agent of claim 14 wherein the traffic controller reorders the DSL traffic portion and the cellular traffic portion based on a first bandwidth associated with the DSL backhaul and a second bandwidth associated with the cellular backhaul.

17. The access gateway agent of claim 14 wherein the traffic controller reorders the DSL traffic portion and the cellular traffic portion based on a first delay associated with the DSL backhaul and a second delay associated with the cellular backhaul.

18. The access gateway agent of claim 14 wherein the DSL interface and the cellular interface are bonded based on at least one policy within a plurality of user-configurable policies.

19. The access gateway agent of claim 18 wherein the user-configurable policies comprises (1) maximizing speed across a combination of the DSL interface and the cellular interface, (2) filling the DSL traffic portion up to a threshold before filing the cellular traffic portion, (3) blocking traffic to a device coupled to the TCP interface, and (4) identifying a set of trusted devices coupled to the TCP interface.

20. The access gateway of claim 18 wherein the user-configurable policies comprises a failure detection on the DSL backhaul or cellular backhaul.

21. The access gateway of claim 18 wherein the user-configurable policies comprise an identification of a type of the TCP traffic.
