In communication systems, a carrier grade or carrier class EMS NMS refers to a software application that is reliable, well tested and proven in its capabilities. Carrier grade EMS NMS systems are designed and tested to meet or exceed “five nines” high-availability standards, and provide seamless fault recovery in the event of software or hardware failure through 1:1 or 1:N redundancy schemes. The carrier grade description readily applies to the vendors’ network equipment and is quantified by standards organizations with regard to service down time and service availability criteria.
Not all network equipment vendors need to build carrier grade equipment(s), but their actual EMS NMS offering should comply with carrier grade requirements. The rise of the intelligent, software powered communications network has forced Communication Service Providers (CSPs) to place additional network element management system feature demands on their equipment vendors to provide next generation management solutions that scale and adapt to manage new features and services
In order to meet these demands EMS NMS should incorporate rich carrier-grade features out of the box. They should not need any code changes, just configuration file changes to get the EMS up and running as long as the devices support standard protocol interfaces.
EMS NMS Deployment and Scalability
In today’s communication networks, managed network elements can be deployed in a plethora of deployment configurations. They range from home network elements e.g. Femto cells, xDSL or FTTH terminals to centralized resources dealing with the traffic flows from many thousands of customers e.g., aggregation switches, DSLAM, OLT, Transport and Core routers as well as video, wireless servers. A robust EMS NMS solution should match the vendor’s deployment needs and scale as demand grows.
We recently drafted a white paper on this topic that discusses:
The size, complexity and evolution of the networks have created lot of challenges for Network Management platforms. This paper explains five key areas which a network management platform should address to meet the critical needs of a network operator.
- Inventory Management: Network Management software should be able to either manually or automatically discover the critical infrastructure elements of the network.
- Real-time Monitoring: Service providers need to know which alarms need to be fixed immediately and which alarms can be scheduled.
- Openness / Flexibility: A good management framework should be able to adapt and change quickly to service providers’ or OEMs’ evolving business requirements.
- High-Availability (HA): A fault-tolerant and highly available network management environment should assess the critical network management functions that truly need to be highly available(Fault Management For Network Elements).
- Scalability: An NMS platform must provide the ability to grow with the network.
