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.
How Do You Connect to an MPLS Network?
Popular access connections are T1 lines, DS3 bandwidth, fixed location wireless, Ethernet over Copper and fiber optic services. In some cases, business grade DSL may also be used to save cost.
Don't Frame Relay Networks Do The Same Thing as MPLS Networks?
They used to in a simpler way. Frame relay networks use small ATM cells rather than the modern IP network cores of MPLS networks, so they tend to be less efficient. Most carriers are shutting down their Frame Relay networks since the rise of MPLS. The newer MPLS networks tend to be designed for higher speeds to match today's business bandwidth needs.
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.
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.
