Seamless data networking

摘要

A roaming client in communication with an enterprise site through a virtual private network (VPN) gateway maintains an address for a virtual network interface upon becoming a resident client at the enterprise site. A physical interface for the resident includes two valid addresses. Seamless data networking is achieved while promoting routing efficiency by reducing the amount of local traffic addressed to and from the virtual address that is unnecessarily routed through VPN gateways.

主权项

1. A method comprising:
establishing a virtual address for a client associated with a non-secure access network; establishing a virtual interface, associated with the virtual address, enabling the client to access a secure network from the non-secure access network via a virtual private network gateway; responsive to the client detecting a second access network, determining whether a second physical address associated with the second access network is a secure address within the secure network; and responsive to determining that the second physical address is the secure address within the secure network, associating the second physical address and the virtual address with a second physical interface associated with an edge router, wherein a portion of network traffic associated with the virtual address is routed via the second physical interface and the edge router rather than the virtual interface and the virtual private network gateway.
