Abstract

A networked system includes a plurality of information handling systems (IHSs). A networking device couples the plurality of IHSs to a network. The networking device is operable to receive a packet associated with a first network application from a first IHS of the plurality of IHSs. The networking device then determines that a first virtual port is associated with the first network application in a database. The networking device then assign packets received from the first IHS and associated with the first network application to the first virtual port. The networking device then forwards packets received from the first IHS and associated with the first network application over the network using the first virtual port. The first virtual port provides access to a virtual network that is provided for the first network application and configured using network information associated with the first network application.

First claim

determine that the first packet was received from a first network application of the plurality of network applications that is provided on the first networked device;
determine a first subset of the plurality of virtual ports that is associated with the first network application in the memory; and
forward the first packet received from the first network application provided on the first networked device, and subsequent packets received from the first network application provided on the first networked device or at least one second networked device, using the first subset of the plurality of virtual ports.

2. The networking device of claim 1 , wherein the processor is configured to:
retrieve application layer metadata from an application layer in the first packet received from the first networked device, and from an application layer in the subsequent packets received from the first networked device and the at least one second networked device; and
use the application layer metadata to determine that the first packet and the subsequent packets were received from the first network application that is provided on the first networked device and the at least one second networked device.

3. The networking device of claim 1 , wherein each subset of the plurality of virtual ports provides access to a virtual network that is provided for the network application associated with that subset of the plurality of virtual ports.
