Method and apparatus for accelerating CPE-based VPN transmissions over a wireless network
First Claim
1. A method of securely accelerating customer premises equipment based virtual private network transmissions over a carrier network comprising the steps of:
- establishing an encrypted acceleration tunnel between a VPN acceleration client and a VPN acceleration server in response to a VPN acceleration client request for information;
transmitting said VPN acceleration client'"'"'s VPN address and required data information to said VPN acceleration server over said encrypted acceleration tunnel;
establishing an encrypted VPN tunnel between said VPN acceleration server and an appropriate VPN switch thus providing access to the appropriate enterprise content servers, said appropriate Enterprise content server corresponding with said required data information transmitted;
encrypting and transmitting required data corresponding to said required data information from said VPN switch to said VPN acceleration server over said VPN tunnel, said required data is communicated from said appropriate Enterprise content server to said VPN switch prior to encryption and transmission;
decrypting said required data at said VPN acceleration server;
accelerating and encrypting by said VPN acceleration server and transmitting said required data to said VPN acceleration client; and
decrypting said required data in response to said VPN acceleration client receiving said required data.

Abstract
The present invention generally relates to the acceleration of customer premises equipment based virtual private networks (CPE-VPN). To provide virtual private network service from an enterprise network to a mobile client in a secure manner apparatus and method are provided whereby VPN service is provided which allows the wireless network to use data acceleration techniques. This is accomplished by providing a VPN acceleration server that terminates VPN tunnel from the enterprise network, accelerates the data for wireless transmission then encrypts the data for transmission to the mobile client (VPN acceleration client) over an encrypted acceleration tunnel. The encrypted acceleration tunnel may use PKI encryption.
