SLAM (Service Level Agreement Manager) services: control and management of phone channel bandwidth on Premium IP Network

This work presents an advanced service implemantation regarding an automatic control and management of phone channels bandwidth requirements over a Premium IP (PIP) network. This service is implemented by the SLAM (Service Level Agreement Manager) on the Intelligent Node based on the Active Network technology. During the last years “Voice over IP” (VoIP) and IP Telephony has gained an unprecedented success (due to both market and technology evolution): nowadays the main push towards the use of VoIP is the lower cost of the IP network connection with respect to traditional networks. Though such 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 QoS (Quality of Service) features.
