Selection from Fundamentals of EMS, NMS and OSS/BSS [Book] telecom architecture, and some of the major vendors involved in the development of EMS. Before doing the programs, I thought it’s a good idea to dwelve on NMS to understand it better. Network Monitoring System as the name. requirements for the eMS/NMS systems to inter-operate with the eMS, NMS, OSS – Element Management System (eMS), Network management System (NMS).

Its purpose is to partition the functional areas of management into layers. Their work is sponsored by service providers and PTTs from around the world, as well as large equipment vendors and national standards organizations. Able to calculate the traffic packets moved in particular network or sub tutoriap, so that the customers can be billed accordingly.

The Manager component is simply a piece of software that is installed on a machine which when combined, is called the Network Management System that polls devices on your network how ever often you specify for information.

NMS/EMS in Java Programmer’s view

Usually similar kinds of elements equipments are managed by EMS. This protocol has gone through several revisions over the years, dating back to starting with Version 1. Tele Management Forum, formerly the NMF, is a nonprofit, global tutorail that provides the telecom industry with leadership on the most effective ways to streamline the management of communications networks and services. TMN calls for each layer to interface with adjacent layers through an appropriate interface to provide communications between applications, and as such more standard computing technologies can be used.


The manager Software in the previous section polls the agents at regular intervals over Port UDP It is, however, too abstract to use to understand the operational contribution and economic value of EMS’s.

It should be scalable to grow with the requirements and complexity of the network. Element is anything in the network, for example, Printer, Switch, Cell node, Desktop, anything in nme network. It should provide the correct level of management functionality appropriate to the device and to the management environment.

MIB files are the set of Questions that an Manager are allowed to ask the agent. Whether or not a specific function is accomplished via the EMS GUI depends upon whether or not the task is subsumed in an application performed at a higher tktorial. The NML basically has three primary functions: It is important to understand that EMS’s make the link to the NML for tasks such as integrated faultmanagement and flow-through provisioning. The 3 levels of authentication tutoorial as follows:.

All other time only Manager can initiate the communication. EMS’s are now valuable components of the network in their own right and not mere extensions of the NE uttorial interface as EMS’s have often been perceived in the past. Traps ensure that the NMS gets information if an certain event occurs on the device that needs to be recorded without being Polled by the NMS first.

The goal is to provide a common architectural framework nmw object-oriented applications based on widely available interface specifications. This security feature allows you to set authentication based on the user requirements.

NMS/EMS in Java Programmer’s view

Element Manager EMS is a system that manages these elements. Traps are used when the Device needs to alert the Network Management software of an event without being polled. Topics 5 through 8 describe typical tasks that legitimately belong in the four-function domain of an EMS. tuforial


To support management of the traffic between itself and other NEs, the EMS communicates upward to higher-level network management systems NMS as described in the telecommunications management network TMN layered model. These standards covered all aspects of telecommunications from physical cabling specifications to network management information modeling.

Version 2 of the protocol was introduced inwith large improvements in over the first version, including transport mappings, MIB Structure elements and most importantly, improved authentication and security updates. Version 1 was the first version of the protocol defined in RFCs and Not all EMS’s tutotial perform all of these tasks; some will perform these tasks and more; and some will perform unique tasks that target the requirements of a particular NE.

EMS’s also offer sign ificant value via cost- and time-reducing tasks provided in addition to enabling cost-effective development of the TeleManagement Forum high-level processes. EMS’s with open, standard, northbound interfaces provide the solid foundation required for service providers to deploy the TeleManagement Forum—defined, high-level processes by applications at the TMN framework network, service, and BML’s.

There are 2 types of OID’s: If the networked tktorial is SNMP capable, you can enable and configure it to start collecting information and monitor as many network devices as you want from a single point.
