Network Routing, Interconnection and Interworking
Martin P. Clark · 2001
The control of the routing of calls and connections (so-called ‘traffic’) across telecommunications networks is the most difficult but most important responsibility of a network operator. Only by careful planning and management of appropriate call and traffic routing plans can the network operator ensure successful connection of calls and the efficient use of network resources. This chapter discusses the techniques used by network operators in establishing efficient call routing patterns and the special problems caused by network interconnection and interworking, when calls or connections originated in one network have to be passed to another operator's network for completion.
