The service level agreement manager: control and management of phone channel bandwidth over Premium IP networks
Maurizio D’Arienzo, Antonio Pescapè, Simon Pietro Romano, Giorgio Ventre · 2002
This work presents an advanced service implementation regarding automatic control and management of phone channels bandwidth over a Premium (PIP) network. This service is implemented by the SLAM (Service Level Agreement Manager), an Intelligent Node based on the Active Networking technology. During the last years Voice over IP (VoIP) and Telephony have gained an unprecedented success, due to both market and technology evolution. The main push towards the use of VoIP is the lower cost of the network connection with respect to traditional networks. Though networks do not represent a plug-and-play solution to voice delivery, they may disclose a good potential if opportunely rearranged so to be able to support several types of traffic on the same infrastructure. One network for all services: traditional phone, advanced phone with messaging services, data transfer, video streaming and TV broadcasting. Therefore the main issue we have to cope with is the integration of several services on the same network infrastructure, thanks to the use of a flexible network protocol like IP, appropriately modified with the introduction of Quality of Service features.
