Network element
In computer networks, a network element is a manageable logical entity uniting one or more physical devices. This allows distributed devices to be managed in a unified way using one management system.
According to the Telecommunications Act of 1996, the term 'network element' refers to a facility or to equipment used in the provision of a telecommunications service. This term also refers to features, functions, and capabilities that are provided by means of such facility or equipment. This includes items such as subscriber numbers, databases, signaling systems, and information that is sufficient for billing and collection. Alternatively, it's also included if it's used in the transmission, routing, or other provision of a telecommunications service.
With development of distributed networks, network management had become an annoyance for administration staff. It was hard to manage each device separately even if they were of the same vendor. Configuration overhead as well as misconfiguration possibility were quite high. A provisioning process for a basic service required complex configurations of numerous devices. It was also hard to store all network devices and connections in a plain list. Network structuring approach was a natural solution.
With structuring and grouping, it is very well seen that in any distributed network there are devices performing one complex function. At that, those devices can be placed in different location. A telephone exchange is the most typical example of such a distributed group of devices. It typically contains subscriber line units, line trunk units, switching matrix, CPU and remote hubs. A basic telephone service leans on all those units, so it is convenient for an engineer to manage a telephone exchange as one complex entity encompassing all those units inside.
Another good example of a network element is a computer cluster. A cluster can occupy a lot of space and may not fit one datacenter. For enterprise solutions, it is common to locate cluster nodes in different locations, even in different regions (settlements).
In general, an NE can generate two types of maintenance information:
The functional components of surveillance are performance monitoring and alarm/status monitoring, also known as alarm surveillance. In the national and international standards area for telecommunications operations, performance monitoring and alarm surveillance are classified as subcategories of the more general system management functional categories of performance management and fault management, respectively. Maintenance consists of both preventive and corrective procedures that are designed to (a) prevent troubles and identify potential troubles before they affect service, and (b) detect a network failure that impacts performance and make the appropriate repairs. A typical seven-step maintenance process consists of:
Telcordia GR-474 establishes trouble-detecting and reporting criteria for signal transmission failures and internal hardware or software anomalies. GR-474 provides proposed generic requirements that pertain to the Fault and Performance Management functions in transport and switching NEs used for alarm surveillance and control.
