This paper describes the design and the implementation of QoS services in a high speed backbone network as well as a management tool for the service. The services were designed taking advantage of features provided by the MPLS technology and also by using the DiffServ architecture. The supported QoS services include the IP Premium that tries to provide zero packet loss as well as minimum delay and jitter and the Less Than Best Effort service. In addition we implemented a management tool for the service. The scope of this tool is to allow the users to manage their QoS requests (make a new one, edit, delete or view a request). Also the tool performs admission control and produces the necessary configuration that must be applied on the network in order to implement every service{\textquoteright}s request.

Since the Internet community and the Web are expanding every day, the demand for user friendly Web publishing applications is rising. The procedures that could be followed by Internet users in order to publish content on the web till now, were to either buy and read some books on HTML and have some basic knowledge on Web Servers, or pay an ISP a quite substantial amount of money to do it for them. In this paper we rst justify the necessity of the existence of an alternative method for online web pub- lishing. We then describe the method and a tool, called e-DEDALUS, which can be used by many diverse Internet user groups. An Internet user that has no previous expe- rience in programming, or desktop design, will be able to create his/her own Web site, online. The e-DEDALUS tool that will be described in this paper aims at o ering simplic- ity, customisability and multilingual support to a substantial number of WWW users.}, author = {Christos Bouras and Agis Konidaris and C Sintoris and A Apostolopoulos and V Khan} }
