Abstract
This paper is about the implementation of performance monitoring and resource availability solution in transport stratum of Next Generation Network (NGN) over Enhanced Telecom Operations Map (eTOM) framework. Continuous monitoring of performance is done to ensure consistent Quality of Service (QoS) to the users. Monitoring of network parameters such as delay, delay variation, path unavailability, packet loss ratio is done in the transport stratum of next generation network architecture. Resource and Admission Control Functions (RACF) will interact with Management functions for performance measurement of NGN transport control traffic and transport services and allocate resources to the customers whose QoS requirements are satisfied. The above functionalities are mapped into NGN business elements, defined by eTOM framework.
Highlights
According to ITU-T [1][2] NGN definition, a next-generation network (NGN) is designed to support new services in service stratum of NGN architecture
To support the negotiation service resource requirements as specified in the paper [4] entitled, “Functional Architectural Design of Negotiation Service Component in NGN ITU Architecture”, this paper provides a better way of resource provisioning
It describes the interaction of Management of Performance Measurement (MPM) functions with components of Negotiation Service Control Functions (NSCF) and components of transport stratum in NGN
Summary
According to ITU-T [1][2] NGN definition, a next-generation network (NGN) is designed to support new services in service stratum of NGN architecture. It describes the interaction of Management of Performance Measurement (MPM) functions with components of Negotiation Service Control Functions (NSCF) and components of transport stratum in NGN. It monitors the performance of request continuously and sends performance degradation report if there exists any fall in the service network parameters and fault parameters. PMR-FE (Performance Measurement Reporting - Functional Entity): PMR-FE is an entity, used to send the generated performance degradation report to RACF It does continuous monitoring of resource provisioning. NMRC-FE (Negotiation Resource Media Control Functional Entity): NMRC-FE is used to send the tickets after the negotiation process
