METHOD AND SYSTEM OF CONNECTING TO A MULTIPATH HUB IN A CLUSTER
In one aspect, a computerized method useful for connecting to a multipath hub in a cluster includes the step of, with a gateway in a same network as the cluster, receiving, from a branch edge, a request to connect to a logical identifier (ID) of the multipath hub. The gateway recognizes a logical ID representing a cluster. The gateway determines a least-loaded edge in the cluster to be the multipath hub. The gateway returns a connectivity information for the multipath hub. The branch edge configures a tunnel to the multipath hub.
1 . A method comprising:
detecting, by a branch edge device, a loss of connectivity to a multipath hub, the multipath hub being associated with a logical ID;
sending, by the branch edge device, a new connection request to a gateway with the logical ID of the multipath hub;
selecting, by the gateway, a new least loaded hub from a cluster of multipath hubs and returning a connectivity information for the new least loaded hub to the branch edge device; and
establishing, by the branch edge device, a tunnel connectivity with the new least loaded hub using the connectivity information.
2 . The method of claim 1 , wherein the gateway logs the connectivity status of each reestablished connection.
3 . The method of claim 1 , further comprising providing a notification for the loss of connectivity.
4 . The method of claim 1 , further comprising providing a notification for establishing the tunnel connectivity.
5 . The method of claim 1 , wherein the new connection request comprises updated utilization statistics of the branch edge device.
6 . The method of claim 1 , further comprising prioritizing the new least loaded hub based on a predetermined hierarchy for the cluster of multipath hubs.
7 . The method of claim 1 , wherein the connectivity information comprises security credentials for establishing the tunnel.
8 . The method of claim 1 , further comprising encrypting the connectivity information.
9 . The method of claim 1 , wherein the new least loaded hub is selected based on monitoring of hub utilization.
10 . The method of claim 1 , wherein the branch edge device adjusts its traffic routing policies based on the connectivity information.
11 . A non-transitory machine readable medium storing a program executed by one or more processing units, the program comprising sets of instructions for:
detecting, by a branch edge device, a loss of connectivity to a multipath hub, the multipath hub being associated with a logical ID;
sending, by the branch edge device, a new connection request to a gateway with the logical ID of the multipath hub;
selecting, by the gateway, a new least loaded hub from a cluster of multipath hubs and returning a connectivity information for the new least loaded hub to the branch edge device; and
establishing, by the branch edge device, a tunnel connectivity with the new least loaded hub using the connectivity information.
12 . The non-transitory machine readable medium of claim 11 , wherein the gateway logs the connectivity status of each reestablished connection.
13 . The non-transitory machine readable medium of claim 11 , wherein the program further comprises instructions for providing a notification for the loss of connectivity.
14 . The non-transitory machine readable medium of claim 11 , wherein the program further comprises instructions for providing a notification for establishing the tunnel connectivity.
15 . The non-transitory machine readable medium of claim 11 , wherein the new connection request comprises updated utilization statistics of the branch edge device.
16 . The non-transitory machine readable medium of claim 11 , wherein the program further comprises instructions for prioritizing the new least loaded hub based on a predetermined hierarchy for the cluster of multipath hubs.
17 . The non-transitory machine readable medium of claim 11 , wherein the connectivity information comprises security credentials for establishing the tunnel.
18 . The non-transitory machine readable medium of claim 11 , wherein the program further comprises instructions for comprising encrypting the connectivity information.
19 . The non-transitory machine readable medium of claim 11 , wherein the new least loaded hub is selected based on monitoring a hub utilization.
20 . The non-transitory machine readable medium of claim 11 , wherein the branch edge device adjusts its traffic routing policies based on the connectivity information.
