All-IP is becoming the dominant networking paradigm for the present century. The evolution towards an all-IP core network infrastructure continues unabated, with an enriched IP layer being sometimes the unique networking player on top of WDM links. Even more impressive is the scenario currently envisioned in the access domain. On the one side, IP over switched Giga (or 10-Giga) Ethernet is replacing the traditional access means. On the other, the widespread deployment of non-3G wireless access networking technologies (such as 802.11 WiFi wireless LANs or 802.16 WiMax wireless MANs) require IP to take roles traditionally envisioned for 3G core networks.
Key to the success of IP is its flexibility, that allows the integration within one network of a number of systems which at lower layers may have different characteristics, as well as the transport over a common infrastructure of the traffic flows generated by a variety of applications (web browsing, e-mail, telephony, audio and video distribution, multimedia multicasting, financial transactions, ...), whose performance requirements may be extremely different.
This situation has generated a great interest in the development of techniques for the provision of quality of service (QoS) guarantees in IP networks offering a variety of services through a range of different user interfaces (wired and wireless, of different nature), in the developement of mapping strategies between the end-to-end QoS models provided at the IP layer with the local QoS solutions offered by the underlying wired/wireless networking technologies, and in the development of tools for the network optimization under QoS constraints.
In 2003 and 2004, the Italian Ministry for Education, University and Research has been funding a large research programme on these topics, coordinated by CNIT, and named TANGO (Traffic models and Algorithms for Next Generation IP networks Optimization - see http://tango.isti.cnr.it/).
QoS-IP 2005 is organized by TANGO, and aims at the presentation of high-quality recent research results on QoS in IP networks, and at the dissemination of the most relevant research results obtained within the TANGO programme.
A special issue of Computer Networks will comprise extended versions of the best papers of QoS-IP 2005.
