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 is a Service Level Agreement?
An SLA or Service Level Agreement is often part of the contract
between a business and telecom carrier for line or network services.The SLA spells out the expected availability
of the service and what penalties the carrier is liable for downtime or parameters out of spec.
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.
Advantages of Voice over MPLS
MPLS networks have the quality of service features needed to insure low levels of latency, jitter and packet loss to ensure high quality voice transmission. You avoid toll charges by keeping your internal phone calls on the MPLS network that connects your various business locations.
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.
