tw telecom’s IP services deliver high-quality, high-speed connections for companies who depend on their IP services for critical applications.
tw telecom operates a national 10G IP/MPLS backbone with a redundant IP core architecture, diverse network routes, and strong peering relationships with regional, national, and international networks to ensure traffic reaches its destination quickly and reliably.
MPLS technology is used to switch high-speed traffic to and from the Internet and across our backbone. This technology provides quality-of-service and added traffic-engineering capabilities to our network. The backbone is designed to promote availability, survivability and diversity in order to provide high quality services to our customers.

12 Month Network Statistics for 2009
The following is an explanation of the tw telecom’s IP backbone performance measurements of Latency and Packet Delivery.
Network Latency
Defined by tw telecom as the round-trip delay for a packet to travel between two endpoints (tw telecom designated regional route servers) within tw telecom’s IP network backbone. The average round-trip delay is measured in milliseconds. The average round-trip network delay (“Latency”) is measured on an ongoing basis every 15 minutes to adequately determine consistent monthly average performance levels for packet delay between designated regional route servers.
Network Packet DeliveryDefined by tw telecom as the percentage of packets delivered in a data ping between two endpoints (tw telecom designated regional route servers) within tw telecom’s IP network backbone. Packet delivery is calculated as 100 minus the percentage of packets lost during a transmission (i.e., 100 - % Packet Loss = Packet Delivery.) The average packet delivery is measured on an ongoing basis every 15 minutes to adequately determine a consistent average monthly performance level for packets actually delivered between designated regional route servers.
Jitter is defined as
The round-trip variation in the delay of packets between two points within tw telecom's IP network (IP POPs). Jitter is reported in milliseconds and measured on an ongoing basis every 5 minutes. The performance information stated on this site may not reflect the actual performance experienced by individual customers. Acceptable threshold level: Customer's voice or video service may see performance impairment above this line.
