Nokia Layer 2/3 VPN Services

In this article we will talk about Nokia VPN Service Types used in Nokia Service Routers. Why Nokia use “Service Router” term for their service routers? This is because, different Nokia VPN Services are given to customers through these routers.   Services that are given with Service Routers can be divided to two group. One is providing “internet connection” to customer. The other group provide L2/L3 Nokia VPN Service Types to customers.   The internet connection is provided with IES (Internet Enhanced Service) throught service routers. The VPN connection is provided under three service. These services are VPWS (Virtual Private Wire Service), VPLS (Virtual Private LAN Service) and VPRN (Virtual Private Routed Network). VPWS and VPLS are L2 VPN service. VPRN is Layer 3 VPN service.   To sum up the services given under Nokia (formerly Alcatel-Lucent) service routers, let’s check these services orderly.
