Overview typical solution with federation

A federation is a special trust frame or trust network for 
users of IT and telecommunication systems, which creates 
a secure structure for communication between organiza-
tions and companies.

Within the frame of this structure, every organization de-
fines the quality of the information which it would like 
to reveal and decides which services and systems may be 
used for the exchange of information. Typical commu-
nication services which are used today on the base of a 
federation are presence management and instant mes-
saging (chat). The presence management of a federation 
allows the exchange of presence information with, for 
example, partners or customers beyond company bor-
ders.

If somebody is online and available then one can get in 
touch ad hoc via phone or send a text message and can 
expect an immediate answer (instant messaging, chat). 
Furthermore, ProCall provides even more functions: 
There is, for example, the possibility of being informed 
about any change of the presence status of a certain per-
son (tagging). This is an extremely helpful function if you 
are waiting for a person to return to their workplace be-
cause you need information urgently. 

This is noticeable in its similarity to social networks func-
tions. Therefore ESTOS sees the federation as key tech-
nology for the employment of Web 2.0 applications in a 
business environment.
