Introduction


Service providers (SPs) and large enterprise customers (LECs) must deliver different services over a common infrastructure so that they don't interfere with one another (in other words, so that they pass like ships in the night). Multiservice switching networks achieve this goal. This book's objective is to shed light on the general architecture of multiservice switches and to present case studies on MPLS and PNNI, as well as both protocols running simultaneously. This helps engineers who design, deploy, and troubleshoot networks that use the BPX/IGX/MGX families of multiservice switches.

SPs and LECs offer managed VPN services and circuit emulation to enterprise customers and wholesale DSL services to ISPs and NSPs. In addition, SPs and LECs offer traditional ATM transport services from T1 to OC-48 using the same common infrastructure. They provide not only ATM PVC transport, but also lower-cost ATM SVC services.
