This book constitutes the refereed proceedings of the Second IFIP-TC6 Netw- king Conference, Networking 2002. Networking 2002 was sponsored bythe IFIP Working Groups 6.2, 6.3, and 6.8. For this reason the conference was structured into three tracks: i) Networking Technologies, Services, and Protocols, ii) Perf- mance of Computer and Communication Networks, and iii) Mobile and Wireless Communications. This year the conference received 314 submissions coming from 42 countries from all?ve continents Africa (4), Asia (84), America (63), Europe (158), and Oc- nia (5). This represents a 50% increase in submissions over the?rst conference, thus indicating that Networking is becoming a reference conference for wor- wide researchers in the networking community. With so manypapers to choose from, the job of the Technical Program C- mittee, to provide a conference program of the highest technical excellence, was both challenging and time consuming. From the 314 submissions, we?nallys- ected 82 full papers for presentation during the conference technical sessions. To give young researchers and researchers from emerging countries the oppor- nityto present their work and to receive useful feedback from participants, we decided to include two poster sessions during the technical program. Thirty-one short papers were selected for presentation during the poster sessions. The conference technical program was split into three days, and included, in addition to the 82 refereed contributions, 5 invited papers from top-level rese- chers in the networking community.
