What Does MPLS Stand For?
MPLS stands for Multi-Protocol Switching Network. MPLS networks are privately owned "cloud" networks that use special tag switches and routers rather than IP addressing to determine source and destination. The multi-protocol aspect means that nearly any data protocol can be transported, making MPLS networks highly versatile.
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.
Transparent LAN Service
VPLS is sometimes called Transparent LAN service. That’s because WAN communications moves from level 3 to level 2. Your connection to the network is via a managed edge switch that is provided by the network operator. The inherent broadcast nature of Ethernet is preserved, creating a “plug and play” environment as new services are added to the network and discovered by other members connected to the VPLS.
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.
How MPLS Connections Are Defined
You specify the types of connections you want and the network provider sets up the label switching routers to provide this specific service. If you need to add locations or change the way you want to connect, there are no wiring changes that need to be made. The network provider will simply reprogram your service to meet your new specifications.
