nLayer Data Transport services provide robust and cost-effective transport solutions, delivered across the nLayer all-optical nationwide MPLS converged infrastructure.

nLayer Data Transport works by mapping a physical interface at a Provider Edge (PE) router onto an MPLS Label Switched Path (LSP). Native Layer 2 Protocol Data Units (PDUs) from Ethernet, SONET, or ATM interfaces are transmitted via the LSP on the nLayer MPLS Network, to the opposite side PE router where the label is removed. The original PDU is then transmitted to the opposite Customer Edge (CE) device.

nLayer Data Transport is a fully transparent service, providing a dedicated point to point Layer 2 private line service. The customer may transparently pass any Layer 2 or Layer 3 protocol data necessary to support their application, including Ethernet 802.1q VLAN tags. For Ethernet services, the Customer Edge device can also be a Layer 2 switch.

Unlike traditional TDM-based transport service such as SONET, which provide a fixed capacity circuit only, nLayer Data Transport is packet switched over our converged MPLS infrastructure. This means that extra capacity is available on demand, allowing customers to burst beyond their committed bandwidth levels, instead of dropping the excess data. By shifting the cost of transport from a fixed expenditure to a cost of revenue, customers can see significant cost savings.

nLayer Data Transport provides several flexible billing options, including point-to-point, multi-point, flat-rate, and usage-based service. For customers with many sites, nLayer Data Transport in a multi-point configuration can provide a scalable and cost-effective alternative to legacy ATM services.

• Bandwidth on demand. Because nLayer Data Transport is a packet switched service, extra capacity is already available across the uncongested and scalable nLayer MPLS Network.



• Revolutionary cost savings. Only pay for the bandwidth that you actually use, rather than the maximum you can possibly use.



• Scalability. nLayer Data Transport services scale from DS-3 to OC-48 (2.488Gbps) interfaces and beyond.



• Future-proof technology. The nLayer MPLS-enabled Network is constantly being upgraded as capacity demands dictate. nLayer Data Transport services are scalable to any speeds, on any future interfaces, including OC-768c.



• Rapid provisioning. Activate new services quickly, eliminating the need to order additional capacity months ahead of demand as with traditional services.



• Service protection. nLayer Data Transport is a fully protected service, on par with SONET protection. MPLS Fast Reroute pre-calculates and signals service protection LSPs, for rapid fault detection and repair in less than 50 milliseconds.



• Aggressive Service Level Agreements (SLAs). nLayer Data Transport service is backed up by industry leading SLAs for latency, packet delivery, and trouble repair times, comparable to SONET private line services.
