This text discusses the problems of ATM integration into large corporate systems currently managing multiprotocol-based networks. It is intended for network professionals who are integrating ATM into networks running on such protocols as TCP/IP, SNA and APPN in order to enhance transmission of data, video and sound - whilst protecting vital business-dependant data which must remain secure and reliable. The book offers technical detail on principles of ATM traffic management, signalling and routing, which should leave the reader with a detailed understanding of effective and protective ATM integration.
