Abstract
A system and method for reducing processing load on an encapsulated data packet transmitted over a virtual private network. The method includes handling an initial encapsulated data packet to be transmitted over an established VPN tunnel connection to a receiving device, the initial encapsulated data packet having a Layer 2 (L2) protocol header, an IP data packet and at least one framing element; removing the at least one framing element; removing the L2 protocol header; appending an alternate L2 encapsulated protocol header to the IP data packet to generate a modified encapsulated data packet, wherein the alternate header contains information of the IP data packet; and sending the modified encapsulated data packet to the receiving device, wherein the alternate encapsulated protocol header allows the receiving device to handle the IP data packet using less computational resources in comparison to receiving the initial encapsulated data packet.
