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.
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.
How MPLS Enables VoIP
Enterprise VoIP phone systems offer performance and cost savings advantages to businesses, but only if voice quality can be maintained. MPLS networks are specifically designed to maintain voice packet integrity.
MPLS Network Speeds
MPLS networks can run at any network speed and are being adopted by major carriers as the multipoint to multipoint technology of choice. For this reason, MPLS is fast replacing Frame Relay.
