Private Port Ethernet Virtual Private LAN Service (VPLS)
SECURE, RELIABLE ETHERNET SOLUTIONS FOR YOUR LONG-HAUL DOMESTIC NETWORKING NEEDS

CenturyLink^™ Private Port VPLS provides large bandwidth solutions designed to meet your critical business application needs. CenturyLink combines the resiliency of its next-generation network with the ease and convenience of standard Ethernet interfaces. CenturyLink Private Port VPLS is for critical business applications that require low latency and high availability — for example, connecting data centers, large file transfers/sharing for digital imaging, videoconferencing, gaming, multimedia, broadcasting, storage area networking, service oriented architectures with hosting components, as well as business continuity and disaster recovery applications. CenturyLink Private Port VPLS provides you with secure, reliable connectivity that you can depend on — from a provider with experience and a commitment to service that you can trust.

Description

CenturyLink Private Port VPLS provides a point to point connection over a private based IP network. CenturyLink Private VPLS provides Ethernet based connections between two geographically dispersed sites. The service is not sensitive to distance, making it not only a secure connection but cost effective as well. Similar to traditional private line services, you have the flexibility that comes with managing your own routes. CenturyLink Private Port VPLS also provides protocol transparency enabling support for protocols not typically supported in traditional layer 3 (MPLS) private networks.

CenturyLink Private Port VPLS provides reliable long-haul network connectivity between your locations. The solution is suitable for data, voice and video applications.

CenturyLink Private Port VPLS is offered in the following speeds:

• 10 Mbps (available in increments of 2 Mbps)
• 100 Mbps (available in increments of 10Mbps)
• 1000 Mbps (available in increments of 100Mbps)

Benefits

• Availability: CenturyLink offers service at locations throughout the United States.
• Convenience: CenturyLink Private Port VPLS provides the convenience of Ethernet, giving you routing flexibility and control to quickly scale bandwidth from megabits to gigabits. CenturyLink Private Port VPLS is protocol independent, supporting IP, IPX and other protocols.
• Performance: Delivers optimal uptime for your mission-critical applications.
• Competitively priced: An option between flat rate or tiered pricing - allowing you to only pay for only what you need and no more.
• Expertise: CenturyLink has years of experience in designing and delivering technical solutions to meet your business needs.

How It Works

CenturyLink Private Port VPLS connects your locations using VPLS-based technology to create a point to point connection designed to carry real-time and data applications over a single customer interface. CenturyLink Private Port VPLS can support a point to point implementation in a single bridged domain over an MPLS network. Instead of a serial interface, an Ethernet interface is used to deliver a layer 2 broadcast domain that is capable of learning and forwarding Ethernet MAC addresses. In areas where Ethernet may not be available, CenturyLink can bridge a location by delivering IP access using frame relay or ATM encryption, allowing you to obtain point to point access across the nation.
