Generic performance management of multiservice networks

This paper discusses various approaches to the development of an integrated and automated network performance measurement tool. Adopting an object-orientated approach to the entire system design can assist this requirement for intelligence in a distributed manner. The authors have found the JAVA language to greatly assist in this task and this language has been used for all aspects of the system from traffic generation/reception, to the database and display systems. Finally, examples of the systems have been developed and implemented at various levels, from experimental operations on ATM networks, to a prototype operational system on BT's commercial SMDS (Switched Multi-megabit Data Service) networ

Architecture for the management and presentation of communication network performance data

Packet based data networks such as BT's Switched Multi- megabit Data Service (SMDS) have performance that varies with customer behaviour, network design and network pro- vision. This paper describes a system researched to monitor such networks from the customer's perspective, but on be- half of the operator. The information generated allows the operator to determine whether the network is performing correctly or whether changes or customer load will require the network to be changed in some way. Such networks are increasing important as many parts of the Internet are built on similar technologies. The paper speci cally considers an architecture which encompasses all the main functionality involved in perfor- mance management of networks. Consideration is given to the management and dissemination of the data collected. A database to enhance network data mining performance is described. A method to identify the periods of signi - cance in the measurement data based on a statistical test and a neural network is incorporated into a realisation of the architecture. In addition, a novel mechanism for the real-time presentation of the network performance data in an operator-friendly manner is given
