A practical guide to understanding multiservice switching architecture and designing and using MPLS and PNNI implementations using Cisco IOS (r) and Cisco's BPX (r), IGX (tm), and MGX (tm) product line Cisco MultiService Switching Networks offers indispensable information on how to: Maintain IP QoS in the cell-based MPLS network and deploy MPLS VPNsPartition multiservice switching network between MPLS and PNNI domain and plans to expansionBuild redundancy into the multiservice switching network and minimize single point failureUnderstand VSI protocol and how to solve problems associated with itEffectively utilize IISP and routing AINI in PNNI networkUnderstand and deploy SVC signaling and hierarchical PNNI and plan ATM addressingDimension and size Points of Presence and understand the scale and oversubscriptionUnderstand "ships in the night" and deploy multiple controllers Service providers and large enterprise customers are faced with the goal of providing different services in public infrastructure so that they do not interfere with each other. multiservice switching networks achieve this goal. Cisco MultiService Switching Networks highlights the general architecture of multiservice switches and presented case studies on MPLS and PNNI as well as both protocols running simultaneously. This will help the engineers who design, deploy, and troubleshoot networks that use the BPX (r) / IGX (tm) / MGX (tm) family of multiservice switches. Cisco MultiService Switching Networks are designed to be flexible and allow you to easily move between chapters and sections of chapters to cover only the material you need.
