Introducing the VPN Gateway

SSL Acceleration

The VPN Gateway can function as a peripheral Secure Sockets Layer
(SSL) offload platform that attaches to a Nortel Application Switch or a
comparable switch from another vendor. (The VPN Gateway can also
operate in standalone mode, i.e. without being connected to a switch.)

The VPN Gateway performs a TCP three-way handshake with the client
through the Nortel Application Switch and performs all the SSL encryption
and decryption for the session. Combined with the load balancing
features of the Nortel Application Switch, the VPN Gateway offloads SSL
encryption/decryption functions from back-end servers.

For examples on how to configure the VPN Gateway for SSL Acceleration,
see the Application Guide for SSL Acceleration.

For more information about the basic operations of the VPN Gateway, see
the "Public Key Infrastructure and SSL" chapter in the Application Guide
for SSL Acceleration.
