CenturyLink™ architecture provides flexible transport and application services to agencies, providing them with a one-stop shopping experience. Customer applications — whether voice, data or a combination of the two — are all supported by a full range of Service Enabling Devices. Our devices have been selected with Class-of-Service (CoS) mechanisms, such as IP Precedence (IPP) and Class-Based Weighted Fair Queuing (CBWFQ), which are needed to enable latency and jitter-sensitive applications when combined with other data services.
