What is Ethernet over Copper Access?
Ethernet over Copper, or EoC, uses copper transmission lines rather
that fiber optics. By using a proprietary modulation scheme, existing copper telco pair can be bonded to transport Ethernet bandwidths from 3 to 50 Mbps.
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.
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.
How Does Label Switching Work?
Label switching technology tags the input packets with their source, destination and quality of service requirements. Tag switches or label routers then efficiently get that packet to its destination intact.
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.
