API-Oriented Traffic Analysis in the IMS/Web 2.0 Era

This paper presents an analysis method for dealing with API-oriented traffic, one of the major operational challenges in the IMS/Web 2.0 era which must be overcome in developing a highly stable and reliable communication system. Traffic evaluation methods for the commercial i-mode service in Japan are being extended to address this issue. In particular, we suggest that API traffic models are defined based on process sequences and reflected in the performance evaluation of nodes in a system. Network capacity planning should deal with the impact of estimated API traffic on a mobile network, especially gateway modules. Our proposal enables mobile operators to construct a highly stable and reliable system which supports service innovation by providing APIs to application developers.
