![]() ![]() ![]() The WLAN AP acts as a bridge, switching Ethernet frames into a GRE tunnel terminating on an MS-ISA in the WLAN-GW. In case of Layer 3 aggregation, supported connectivity option is Ethernet over GRE (or Eth-over-MPLS over GRE) tunnel originating from the AP/AC,Īnd terminating on the WLAN-GW. In case of Layer 2 aggregation the connectivity to the WLAN-GW could be tagged or untagged Ethernet. WLAN connectivity to the WLAN-GW could be over a Layer 2 aggregation or an Layer 3 aggregation network (typical when WLAN-GW is upstream of an existing BNG or CMTS). WLAN-GW functions could be on a standalone 7750 as shown in Standalone WLAN-GW or could be an add-on functionality on existing 7750 based BNG as shown in WLAN-GW functions on existing BNG. The connectivity from WLAN AP or AC can be over any existing access technology (DSL, PON, Fiber, DOCSIS, and so on), with Ethernet based connectivity from the access node (DSLAM, OLT, Eth MTU, Layer 2 CMTS) to the WLAN-GW. The 7750 SR serves as a WLAN Gateway (WLAN-GW) providing Layer 3 termination and ESM for these subscribers. The WLAN access can be from public hot-spots (indoor or outdoor APs), venues, enterprises, or home-spots (with public SSID). ![]() The WLAN access enables a service provider to offer a mobile broadband service to its subscribers or to offload traffic on its or a partner’s macro cellular (3G/4G) network. This solution set adds support for managing subscribers gaining network access over WLAN. ![]()
