International Ethernet VPLS
Availability of International VPLS and other standardized Ethernet WAN services
By: John Shepler
Global Crossing is circling the globe with standards-based Carrier Ethernet services under the umbrella of its EtherSphere solutions portfolio. For multinational corporations and other companies with an international reach, this offers one-stop shopping for a network that unites geographically diverse business locations.
What is EtherSphere?
EtherSphere offers a number of Ethernet services that have been established as standards by the MEF (Metro Ethernet Forum). These include Point to Point Ethernet Private Line (EPL) or E-Line and multiple private line or Ethernet Virtual Private Line (EVPL), Point to Multipoint or E-Tree, and Multipoint to Multipoint Ethernet Private LAN or VPLS (Virtual Private LAN Service) E-LAN.
The Smart Demarcation Network Interface Device
This suite of standard Ethernet services accommodates whatever connectivity is needed to interconnect multiple locations. All connections are made using EtherSphere’s Smart Demarcation Network Interface Device (NID). This allows the network to monitor performance end to end, perform traffic management and offer end to end SLAs (Service Level Agreements). Customers have administrative access through the Global Crossing uCommand online portal.
Supported Ethernet Speeds
The Smart Demarcation NID supports 10 Mbps, 100 Mbps and 1000 Mbps Ethernet port interfaces. Bandwidth is highly scalable and can be ordered in committed data rates from 1 to 10 Mbps in 1 Mbps increments, 10 to 100 Mbps in 5 Mbps increments, 100 to 1000 Mbps in 25 Mbps increments, 1000 to 2000 Mbps in 100 Mbps increments and greater than 2 Gbps upon request.
Multiple Classes of Service
There are six classes of services supported on the network that are identified as premium, premium plus, enhanced and enhanced plus, and basic and basic plus. The service level agreements can be POP to POP or end to end with metrics that include frame delivery, frame delay, and delay variation by class of service, plus installation and mean time to repair.
Why Use Carrier Ethernet?
One beauty of Carrier Ethernet is the ability to provide layer 2 switched Ethernet service over wide area networks, including international destinations. VPLS can interconnect data centers and remote locations in a bridged LAN arrangement that includes all of a company’s offices. With simple Ethernet interfaces at every location, connections between LANs are greatly simplified compared to creating worldwide networks using traditional telecom services.
Global Crossing's Global Expansion
Global Crossing is expanding this popular EtherSphere service to include more than 40 new locations in the United States, Europe and China by the end of 2011. This will expand the carrier and enterprise offers now available in North America, Europe, the United Kingdom, Asia and Latin America served by 150 locations served by multiservice edge routers. The expansion in China will deploy EtherSphere Layer 2 VPLS to business centers in China through Global Crossing’s extended reach partner, CITIC Telecom CPC.
