Extension of classical IP over ATM to support QoS of the application level

After the introduction of the basic concepts of classical IP over ATM (CLIP), this paper presents an extension to this standard as well as a full analysis of the technical viability of the extension proposal. One of the major drawbacks of CLIP is the co-existence of IP and ATM without quality of service (QoS) support. By extending the functionality of CLIP and redefining the mapping of IP and ATM addresses, QoS can be brought to IP-based applications without requiring any specific definition or implementation changes at the IP layer or above. QACLIP (QoS for applications using CLIP), the newly defined extension, allows applications to request specific QoS for their data transfer use.
