Abstract

In one aspect, a computerized method includes the step of providing process monitor in a Gateway. The method includes the step of, with the process monitor, launching a Gateway. Daemon (GWD). The GWD runs a GWD process that implements a Network Address Translation (NAT) process. The NAT process includes receiving a set of data packets from one or more Edge devices and forwarding the set of data packets to a public Internet. The method includes the step of receiving another set of data packets from the public Internet and forwarding the other set of data packets to the one or more Edge devices. The method includes the step of launching a Network Address Translation daemon (NATD). The method includes the step of detecting that the GWD process is interrupted; moving the NAT process to the NATD.

Dependent claims

A method of establishing a wide area network over cloud datacenters to connect different sites of an enterprise, each site containing a plurality of computers, the method comprising:

deploying, at an edge of a branch first network, a first device to connect to a second device operating in a cloud datacenter and acting as an access point to a second network of the cloud datacenter;
establishing first and second links between the first device and the second device;
establishing at least one tunnel on the first link and designating the first link as an active link;
and
establishing at least one tunnel on the second link and designating the second link as a backup link to use in case the first link fails, wherein the second link is maintained in a hot standby mode during which the at least one tunnel on the second link is active but is not used for transmitting data traffic.
