MPLS & Carrier Ethernet Services

Strong, Flexible Connections and Cost Effective Solutions

Carrier Ethernet

Comtek’s Carrier Ethernet solutions offer a true carrier-class technology. We deliver Ethernet services with the reliability, scale and management capabilities vital to high-bandwidth, mission-critical communications. Comtek provides both Ethernet over SDH/SONET and Ethernet over MPLS solutions

Ethernet over SDH/SONET

Point-to-point Ethernet links are carried over SDH/SONET networks using virtual concatenation (ITU-T G.707) and LCAS (Link Capacity Adjustment Scheme - ITU-T G.7042) to create an appropriate size carrier bundle, and also using Generic Framing Procedure (ITU-T G.7041) to encapsulate the Ethernet frames.

This allows the re-use of the installed base of SDH equipment, and takes advantage of the management and recovery features of SDH to provide high availability and resistance to failures.

Ethernet over MPLS

Ethernet services are carried over IP/MPLS networks making use of a wide range of IP-related protocols  Ethernet links are transported using MPLS label switched paths (LSPs) inside an outer MPLS “tunnel”. This strategy can support both point-to-point (Virtual Private Wire Service - VPWS) and multipoint (Virtual Private LAN service - VPLS) services.

MPLS Services

Comtek’s MPLS (Multiprotocol Label Switching) service is a flexible, cost-effective wide area network solution for linking all of your locations via a secure and scalable network infrastructure. Advantages of Comtek’s MPLS service include:

Cost Savings:  Depending on the specific mix of applications, and network configuration, MPLS-based services can reduce your costs by 10% to 25% over comparable data services (frame relay and ATM). As companies add voice and video traffic, cost savings can rise to as much as 40%.

Traffic Engineering:  COMTek can set the path that traffic will take through the network, and also set performance characteristics for a class of traffic (voice, video, email, internet traffic, etc.)

VPNs:  Using MPLS, service providers can create IP tunnels throughout their network, without the need for encryption or end-user applications. In addition, MPLS is protected by Comtek’s carrier-class security.

Disaster Recovery:  Comtek’s MPLS-based services greatly improve disaster recovery. Data centers and other critical sites can be connected in multiple redundant ways to the other sites on the MPLS cloud. Secondly, remote sites can quickly and easily reconnect to backup locations if needed, unlike with ATM and frame networks, in which either switched or backup permanent-virtual-circuits are required.
