With the continuing success of Local Area Networks (IANs), there is an increasing demand to extend their capabilities towards higher data rates and wider areas. This, together with the progress in fiber-optic technology, has given rise to the so-called Metropolitan Area Networks (MANs). MANs can span much greater distances than current LAN s, and offer data rates on the order of hundreds of Megabits/sec (Mbps). The success of MANs is mainly due to the opportunity they provide to develop new networking products capable of providing high-speed commu­ nications between applications at competitive prices, which nonetheless give an adequate return on the manufacturers' investments. A major factor in of appropriate networking standards. achieving this goal is the availability Fiber Distributed Data Interface (FDDl) and Distributed Queue Dual Bus (DQDB) are the two standard technologies for MANs for which industrial products are already available. For this reason, this book focuses mainly on these two standards. Nowadays there are several books dealing with MANs, and these look mainly at FDDI (e.g., [2], [92], [118], [141]). These books focus primarily on the architectures and protocols, whereas they pay little attention to per­ formance analysis. Due to the capability of MANs to integrate services, a quantitative analysis of the Quality of Service (QoS) provided by these tech­ nologies is a relevant issue, and is thus covered in depth in this book.

This book presents the revised version of seven tutorials given at the NETWORKING 2002 Conference in Pisa, Italy in May 2002. The lecturers present a coherent view of the core issues in the following areas:- peer-to-peer computing and communications- mobile computing middleware- network security in the multicast framework- categorizing computing assets according to communication patterns- remarks on ad-hoc networking- communication through virtual technologies- optical networks.

This book constitutes the refereed proceedings of the IFIP-TC6 8th International Conference on Personal Wireless Communications, PWC 2003, held in Venice, Italy in September 2003.The 49 revised papers presented together with 6 special track papers, 1 invited paper, 11 project descriptions, 7 work in progress reports, and 8 novel ideas reports were carefully reviewed and selected from 115 submissions. The papers are organized in topical sections on mobile computing, wireless access, sensor networks, transport protocols, performance models, WCDMA, ad-hoc networks, wireless and mobile systems, cellular networks, IPv6, Bluetooth, and security and cooperations in ad-hoc networks.

This book constitutes the refereed proceedings of the Second IFIP-TC6 Netw- king Conference, Networking 2002. 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.
