This is the comprehensive guide to implementing QoS in multiservice networks using IP/MPLS. It helps you: understand the technology components of implementing QoS in a multiservice network; learn how to configure the MPLS QoS functionality in Cisco IOS-configuration details help you deploy QoS in your network; dsign optimal networks with confidence through knowledge of multiple QoS design options; understand the market potential of service differentiation using QoS. Quality of Service (QoS) plays a key role in the implementation of multiservice and converged networks. Industry efforts to achieve convergence have generated a need for increased levels of traffic differentiation. An array of QoS requirements need to be met to support distinct applications (e.g. voice, video, and data) and multiple network services (e.g. IP, Ethernet, ATM) on a single converged, multiservice network. Therefore, QoS has become an integral part of an multiservice, converged network and service implementation. source of information for the design, deployment, and implementation of QoS-enabled services on an MPLS network using Cisco IOS. Readers will gain knowledge of the technology behind MPLS QoS and related technologies and will learn the different design options available to build a multiservice MPLS network. The book covers in detail the behavior and configuration of the rich MPLS QoS functionality in Cisco IOS. It is a solid reference of working configuration examples, but does not intend to be a command reference on the subject.
