packet networks
Mobicents Service Delivery
Platform
Our Background
1) Rhodes VOIP Platform:

Asterisk IP PBX

SIP Express Router

Web front end


Apache

Flash

C, Perl and PHP scripts
Java Proxy
Asterisk Architecture
Analysing the System

Service Creation

Dial plan (Apache-like configuration)

AGI (programming scripts) i.e. bash, Java, C, etc ..

SER configuration (combo of prog lang and UNIX-like
config file format)

Asterisk Application API (C only)

Tight coupling of services and control layer
Next Generation Networks

Definition: “A Next Generation Networks (NGN) is a packetbased network able to provide Telecommunication Services to
users and able to make use of multiple broadband, QoS-enabled
transport technologies and in which service-related functions are
independent of the underlying transport-related technologies. It
enables unfettered access for users to networks and to competing
service providers and services of their choice. It supports
generalised mobility which will allow consistent and ubiquitous
provision of services to users”. [ITU-T Recommendation
Y.2001 (12/2004) - General overview of NGN]
