In addition to offering the standard IP-VPN services such as Class of Service (CoS) traffic routing, the carrier-specific product provides customers with:

 
--  Multiple VPN support across the same interface (up to 10Gbps);
--  The ability to create global private networks through an inbound
    Network-to-Network Interface (NNI) with U.S. termination;
--  Access to XO's Web Portal for service level monitoring and review of
    usage reports 24/7; and
--  A management VPN feature that enables Carrier customers to provide
    their end-users with value-added services.

"The services provided through our Carrier MPLS IP-VPN offering demonstrate XO's commitment to creating value-added products for carrier customers," said Don MacNeil, vice president of XO Carrier Services Operations. "Rather than simply repackaging our MPLS IP-VPN business solution for wholesale, we've added strategic options that allow carriers to use proven, cost-effective solutions for network growth, management and security."

Specifically, XO Carrier MPLS IP-VPN can help international service providers expand their footprint; systems integrators better manage networks for end-users; and content providers securely route content between multiple locations. Moreover, the product offers carriers multiple access options, including Ethernet over copper, and is supported by dedicated carrier provisioning and care groups.

XO Carrier MPLS IP-VPN is also designed to support customers looking to migrate away from legacy Frame and ATM networks to IP-based communications infrastructures. Using the solution, carriers can integrate clients' varying traffic types from existing legacy networks onto one network, facilitating the transition to a single, converged IP communications strategy.

"XO was a pioneer in delivering IP services and has built on this expertise to provide an MPLS IP-VPN platform that wholesale customers can depend upon for the reliable, secure transport of their customers' voice and data traffic," said Cindy Whelan, Principal Analyst, Current Analysis. "Enterprise demand for MPLS IP-VPN services will continue to grow, and XO's Carrier MPLS IP-VPN offers the flexibility in access methods, high-capacity interfaces, service quality assurances and network management tools that carriers need to deliver a first-rate MPLS IP-VPN service to their end-users."

XO Carrier MPLS IP-VPN Features

XO Carrier MPLS IP-VPN enables customers to offer prioritization of mission-critical traffic such as voice, video and data applications over non-urgent traffic types such as e-mail and Web browsing. By prioritizing traffic, clients can safeguard high-priority traffic over low-priority traffic, while not having to increase bandwidth purely to support non-critical applications.

The service also allows for allocating bandwidth and prioritizing applications. What's more, any class of service can utilize up to the full available bandwidth without incurring additional charges. Carrier MPLS IP-VPN offers four classes of service:

 
--  Real Time CoS -- for applications that are very sensitive to latency
    and jitter, such as VoIP.
--  Critical CoS -- for applications that can withstand higher latency and
    jitter, but still need guarantees on both delay and jitter such as video
    applications.
--  Priority CoS -- for applications which need to take priority, but are
    not susceptible to variations in latency or jitter such as database
    applications.
--  Standard CoS -- for applications which can withstand moderate to high
    variations in latency or jitter such as e-mail and Web browsing.
