This book constitutes the refereed proceedings of the 7th Asian Computing Science Conference, ASIAN 2002, held in Hanoi, Vietnam in December 2002. The 17 revised full papers presented together with two invited contributions were carefully reviewed and selected from 30 submissions. The conference was devoted to Internet computing and modeling, grid computing, peer-to-peer systems, and cluster computing. Among the issues addressed are scalable infrastructure for global data grids, distributed checkpointing, list coloring, parallel debugging, combinatorial optimization, video on demand servers, caching, grid environments, network enabled servers, multicast communication, dynamic resource allocation, traffic engineering, path-vector protocols, Web-based Internet broadcasting, Web-based middleware, and subscription-based Internet services.
