SPONTANEOUS VIRTUAL PRIVATE NETWORK BETWEEN PORTABLE DEVICE AND ENTERPRISE NETWORK

摘要

An enterprise network (40) opens a virtual private network tunnel (42) with a data center (44) by sending the data center a data request (50) that includes a uniform resource identifier. The data center responds by sending the enterprise network ongoing reply data. A user (10) wishing to access network data (22) of the enterprise network (40) transmits an access request (70) to the data center (44). The data center (44) authenticates the identity of the user (10) and transmits the access request (70) to the enterprise network (40). The enterprise network (40) responds to the access request (70) by performing acts upon the network data (220) and/or by returning network data (22) to the data center (44) such that the user (10) is enabled access to the network data (22). In an alternative embodiment, the data center (44) caches a copy of network data 9220 to be retrieved by the remote user (10) when the same network data is disconnected from the enterprise network (40).
