30 Nov 2006 18:14:50 Element Management System An Element Management System (EMS) is a centralised service that manages one or more of a specific type of Network Elements (NEs). A Network Element is basically a unit of manageable hardware equipment combined with software that provides telecommunications function and can be controlled through an element manager. A group of interconnected Network Elements constitute a Network. An EMS provides complex, standards-based management and control of MultiService Switching (MSS) product functions. EMS handles switches for various protocols including Frame Relay, ATM, SMDS and IP switch networks on one platform. In combination with the MultiService element manager, the EMS provides comprehensive management solution based on Telecommunications Network Management (TNM) industry standards, allowing the user to smoothly integrate and make the system compatible with prevailing or new hardware gadgets and other network management systems. EMS provides the basis for the implementation of TNM–layered Operations Support System (OSS) architectures that assist service providers in meeting customer requirements for swift deployment of new services and matching rigorous Quality of Service (QoS) demands. In the last decade, the telecommunication network has witnessed great transformation. The earlier network was fundamentally planned for switched-voice traffic and was fairly simple as it was based on copper wires for user access and calls were processed by a network of telephone exchanges. This network, in the course of time, has been able to integrate access, transport and switching of voice, data and video functions. Such network involves a range of complex technologies. As a consequence of the complexity, each element in network technology is attached to an EMS that brings out the best in that technology, while screening its complexity. The present day element and network management applications are expected to provide upgradeable and reliable management solutions. The EMS minimises cost of operations by integrating element management processes and making them simple. The important management functions of EMS include Configuration Management, Performance Management, Policy Management, Fault Management and Security Management. EMS provides functionality for the management of real time sessions including establishing and handling customer policies, performance management tools and statistics about resource usage for the purposes of network and service planning. The EMS is the only mediator of management information and the control of Network Elements. Hence, an EMS is closely matched to a specific network-element type and has to be attached to those NEs in the network in order to facilitate and administer their functioning. Thus, the EMS plays an important role in the total telecommunications-management solution. Link: MetaSwitch Element Management System Content Team -- BSNL Portal -- Intelligroup Asia Pvt. Ltd. |
