Following is the claim for this invention: -

1. In this invention we have a Device Identity Module which will run on the edge router or gateway or at the point in the network closest to the client. The Device Identity Module will identify the unique client device with the help of their unique identifier like Media Access Control (MAC) address and the device user can register the device with the Device Identity Module. If the device registration is successful the user can define different policies like network bandwidth limit for the device, maximum number of connections from the device to handle and the unique group the user belongs to where the network point on which Device Identity Module is running. The group could be a business unit in an organisation or a group of shop owners in a mall, etc. and the group administrator will set more policies for the devices falling in his group. The group administrator could also override certain policies set by the device user when registering. With the help of Device Identity Module customers get better visibility and control over the devices using their network resources. The above novel technique of maintaing information about the devices using the network resources of the customer is the claim for this invention.
