    Performance Monitoring in ATM Networks
    (1998) Arora, Anubhav; Baras, John S.; ISR; CSHCN
    ATM networks provide end-to-end QoS guarantees to connections for their lifetime in the form of bounds on delays, errors and losses. Performance management involves accurate measurement of these parameters and taking control measures, if required, to improve performance. This is very important for real time connections in which losses are irrecoverable and delays cause interruptions in service. In this paper an intelligent management architecture and an information flow model for performance management proposed in the literature is reviewed. A brief description of the related ITU-T standard for performance monitoring is given and several schemes for measurement or estimation of QoS parameters are documented. Future work required in the area is also presented in the last section.
