A VPN is a network composed of hosts and system in different locations. In the past, the most common way to connect these sites was to use an ATM or frame relay leased line, supplied by a service provider. These were traditionally straightforward to provide, as service provider networks were often implemented using a variety of protocols including ATM and frame relay. Recently, service providers have been looking at alternative technologies for creating VPN solutions. For supporting Layer 2 VPN service, MPLS protocol such as LDP, RSVP-TE should be implemented for supporting LSP and LDP proposed by Martini or BGP extended by Kompella. Also, MPLS protocol should be implemented for negotiating the specific virtual circuit. In this paper, we implement the Layer 2 VPN that is controlled by Martini protocol and static. And we evaluate the Layer 2 data traffic including both LSP protection and QoS features. |
