Abstract: Systems and methods to implement a shared access gateway are provided that facilitate the multiplexing of multiple enterprise VLAN segments through a single device that translates the VLAN communications from the multiple enterprise segments on the customer side into VLAN communications for delivery over a network service provider network. A single shared access gateway is deployed that is connected to multiple enterprise side network segments. SVLAN controller modules monitor the enterprise side ports of the shared access gateway and processes communications received from those ports. Each SVLAN controller module uses IVL and SVL to maintain its separate forwarding database as packets ingress from the customer side and get processed by the SVLAN controller module. A plurality of translation functions are employed for proper encapsulation of VLAN traffic for transmission over a particular service provider network.
