SHARED APPLICATION INTER-WORKING WITH VIRTUAL PRIVATE NETWORKS

摘要

A method of providing a shared application infrastructure simultaneously to multiple independent virtual private networks with potentially overlapping IP addresses, involves connecting to an underlying layer 1, 2 or 3 virtual private network offering one or more virtual private networks, determining which virtual private network traffic is being received from or sent into, maintaining logically separate routing tables per VPN to allow overlapping addresses, and providing an application which provides a logical instance of the service to each VPN.
