Abstract

In one aspect, a computerized method of an application routing service includes the step of using a deep-packet inspection (DPI) technique on a first network flow to identify an application. The method includes the step of storing an Internet-protocol (IP) address and a port number used by the application and an identity of the application in a database. The method includes the step of detecting a second network flow. The method includes the step of identifying the IP address and the port number of the application in the second network flow. The method includes the step of looking up the IP address and the port number in the database. The method includes the step of identifying the application based on the IP address and the port number.

Claims22

Dependent claims

A method for implementing a virtual private network (VPN) for an enterprise, the method comprising:

deploying a gateway in at least one public cloud to connect a plurality of premises of an enterprise;
at each of at least two premises of the enterprise, deploying an edge device that automatically connects to the gateway to establish the VPN for the enterprise;
from each deployed edge device, providing to the gateway a set of local subnets of the edge device that is reachable over the VPN;
and
from the gateway, distributing to each particular deployed edge device each set of local subnets provided by each other deployed edge device for the particular deployed edge device to use to forward packets to each other deployed edge device.
