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.
When Should You Use VPLS?
VPLS might be the right service for your company or organization if you need to connect anywhere from a few to a few dozen locations as if they were on a single Local Area Network. Advantages of this approach, compared to a private network arrangement with individual point to point connections back to headquarters, include lower latency, higher efficiency, and lower cost... perhaps much lower cost.
What is Latency?
It is the time delay in the network. In other words, how long it takes to get a packet from node to node. The lower limit is set by the speed of light, which equates to 1 msec per 186 miles in a vacuum.
Why International MPLS Networks?
If you do business internationally and need to connect your far-flung operations, an international MPLS network offers the opportunity to create a full mesh network so that any location can communicate to any other location.
