QoS in IP over ATM Networks
Jorge Carapinha, PT Inovação, Portugal
Quality of Service control is a key requirement for an increasing number of services and applications and will certainly have a vital role in future IP networks. The Integrated Services architecture has emerged as a valid approach to provide IP based applications with Quality of Service. On the other hand, ATM is the high-speed network technology designed to support a wide variety of traffic and provide Quality of Service upon negotiation.
The field trials developed by BTI (http://atm1.emi.dtu.dk/) demonstrated effective integration of IP and ATM between users, supported by PON-based access networks located in Portugal, Denmark and Poland. IP (both IPv4 and IPv6), RSVP and ATM were the key technologies that enabled the implementation of the Integrated Services concept.
