Layer 2 Virtual Private Networks (L2VPN)
VPN standards development
The following figure represents the relevant standards associated with VPNs. World Wide Packets provides leading Ethernet and MPLS-based L2VPNs covering the access and metro edge domains.
Per-Port L2VPN
A World Wide Packets service port can be configured to support a single VC. In this case, all traffic ingressing that service port is carried by the VC with a specific bandwidth profile, and transported to the other endpoints of the VC. In this mode, a single port terminates only one VC. This enables the service provider to provide a dedicated demarcation point for the service. Subscriber specific parameters, such as VLANs and Layer 2 control frames (discussed in a later section), are transported transparently across the service provider’s network.
Per-Port-Per-VLAN L2VPN
A World Wide Packets’ service port can be configured to support more than one L2VPN by associating each C-VLAN with a VC. The traffic ingressing the service port on that VLAN is carried by the VC and transported to the other endpoints of the VC. Several VCs can be terminated on the same port.
Per-port-per-VLAN L2VPN enables service providers to offer distinct services, each with their own bandwidth profile and transported to the other endpoints of the VC, over a single physical service port. This enables the service provider to use only one physical port instead of one for each service and provide a shared demarcation point for the services.
