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’s request.</p>

opportunity for companies and individuals to publish their
ideas, products and everything they would like other peo-
ple to view. 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 oering simplic-
ity, customisability and multilingual support to a substantial
number of WWW users.1 aBouras, Christos1 aKonidaris, Agis1 aSintoris, C1 aApostolopoulos, A1 aKhan, V  uhttp://telematics.upatras.gr/telematics/publications/e-dedalus-dynamic-tool-data-publishing-web
