ervice Provider / Wireline Carrier Solutions

Ethernet is now the dominant technology used in new

carrier network deployments. However, to fully integrate

Ethernet into a service provider network requires more than

just plugging in cables and connecting network switches.

That’s why most Edge-Core Networks’ switches feature

EdgeCOS, our own robust Ethernet switch operating

system, designed to minimize technical difficulties and

simplify set-up wherever possible.

Metro Ethernet Forum (MEF)

Edge-Core carrier Ethernet switches are currently

undergoing Metro Ethernet Forum (MEF) certification.

MEF is the defining body for carrier Ethernet, a global

industry alliance comprising more than 150 organizations

including telecommunications service providers, cable

MSOs, network equipment/software manufacturers,

semiconductors vendors and testing organizations. The

MEF’s mission is to accelerate the worldwide adoption of

carrier-class Ethernet networks and services. The MEF

develops carrier Ethernet technical specifications and

implementation agreements to promote interoperability and

deployment of carrier Ethernet worldwide.

Ease of Access

Years of working with carriers have allowed Edge-Core’s

to design systems that suit various carrier needs. Our

switches offer the following features to enable effortless

deployment and ease of access:

Network ports and management console are located

on the front panel

Fan tray and power supplies are accessible from the

front panel

Interface for alarm

Provider Bridging (Q-in-Q)

VLANs are needed to segment traffic from different

customers on the network. However, the traditional VLAN

customer themselves might implement VLANs of their own,

thereby further complicating the network administration. For

example, how would the carrier differentiate a customer’s

VLAN from their own? Without proper resolution, it is

simply impossible to deliver multimedia service and enforce

different service license agreements.

Edge-Core Networks' carrier Ethernet solutions effectively

address these issues through the use of Q-in-Q.

The 4096-VLAN limitation is removed

Customer VLANs and Service VLANs are effectively

segmented, creating a clear demarcation between carrier

and customer networks.

Quality of service and class of service may be mapped

to different VLANs, so that different service license

agreements may be implemented.

Operation, Administration, Maintenance

The carrier must have at its disposal methods to detect

physical and link layer faults at critical network nodes.

Without this capability, expensive truck rolls are required to

diagnose and mitigate network failures.

Edge-Core Networks' carrier Ethernet solutions aim to

resolve the issue through the use of 802.3ah OAM, which
