This book constitutes the Final Report of COST Action 279, Analysis and DesignofAdvancedMultiserviceNetworkssupportingMultimedia,Mobility, andInterworking, a guided tour of the state-of-the-art work on diverse aspects of modern telecommunications networks design developed within this Action during the four years of its operation, started on July 1, 2001, and ended on June 30, 2005. As stated in its founding charter, its Memorandum of Understanding, the work area of COST 279 is the analysis, design, and control aspects of prese- day networks-quite a wide scope. Behind the unifying fac ,ade put on by the Internet Protocol (IP) network layer, todays networks hide a mess of hete- geneity: heterogeneity at the level of applications, both concerning the traf?c they produce and the network Quality of Service (QoS) they require, and h- erogeneity at the level of network component subsystems, in particular an - creasingly important mobile/wireless access segment.A common ground for the treatment of this disparate set of topics was given by the strong meth- ological component contained in the approach followed in COST 279, with importance placed on the development and application, whenever possible, of analytical techniques and models for the mathematical understanding of the systems under study. The results expected from the Action ranged thus from mathematical models and algorithms as entities of own interest to the und- standing of systembehavior via their application.

On behalf of the IEEE Communications Society, Technical Committee on N- work Operations and Management (CNOM), Manweek 2008 Organizing C- mittee, and members of the IPOM Technical Program Committee, it is our pleasureto present the proceedings of the 8th IEEE Workshop on IP Operations and Management(IPOM 2008),heldaspartofManweek2008duringSeptember 22-26, 2008, on Samos, Greece. ThecurrentInternetisalarge-scaledistributedsystemwhosesub-components suchasaddressing,protocols,algorithms,services,need to scalein time withthe rapid growth of Internet tra?c volumes. Moreover, there is a high level of int- action between di?erent subcomponents of the Internet sometimes in undesired ways - for example, denial of service attacks can jeopardize the operation of a commercial network. With these challenges in place, operations and mana- ment of IP networks have become increasingly important. This necessitates a good understanding of the emerging technical and scienti?c problems in the current Internet, and lessons from such understanding will be particularly - portant for future Internet design and management.Building on the success of the previous events, we wanted IPOM 2008 to focus on network management challenges for the current Internet as well as on future Internet design.
