What Is VPLS?
VPLS is a class of VPN or Virtual Private Network that connects multiple sites to form a single bridged domain. It is implemented using a MPLS or Multi-Protocol Label Switching Network. That makes it protocol-transparent so that all services, regardless of which location the are physically located at, appear to be on the larger LAN that serves all locations.
What are Typical Classes of Service?
Class of Services or CoS is established in MPLS networks to ensure the performance of each packet on the network. CoS classes include real time for voice and video, mission critical for time sensitive applications such as transaction processing, business critical for applications such as database access, and data for lower priority traffic that isn't time sensitive.
Why Type of Traffic Can MPLS Handle?
Because it's multi-protocol, MPLS networks can handle nearly any type of digital traffic you can generate including VoIP and TDM telephone, IP video, and packet data.
How MPLS Enables VoIP
Enterprise VoIP phone systems offer performance and cost savings advantages to businesses, but only if voice quality can be maintained. MPLS networks are specifically designed to maintain voice packet integrity.
MPLS Network Configurations
The MPLS network can be thought of as a cloud that is accessible from many locations. Your service can be set up for a single point to point connection, a hub and spoke replacement for central offices serving many remote locations, or a fully meshed network where any site can communicate with any other site.
