What are the differences between OMC, EMS, and NMS?

OMC-Operation and Maintenance Center
EMS-Network Element Management System
NMX-Network Management System

What is the difference between the OMC, EMS, and NMS of the manufacturer?

However, OMC and EMS generally refer to

NMS is comprehensive

Connected to different devices

OMC refers to the manufacturer's network management system for its own devices.

What is the difference between OMC manufacturers and EMS?

The OMC of current manufacturers is very strong and can cover EMS and NMS

Is the network element layer and Network Layer

EMS refers to the network element layer network management system, and NMS refers to the network layer network management system.

What is the difference between OMC and EMS?

OMC generally refers to the network management system of the manufacturer for its own devices.

EMS refers to the network metadata management system.

Strictly speaking, OMC is not a management system concept, but is now available. OMC generally refers to the manufacturer's management system, which includes Network Element Management and some network management functions.

I said, in the past, most of the OMC had to manage its own device network meta-layer network management, but now many OMC can directly manage the network and go up to the NMS level.

Therefore, OMC and EMS are not necessarily related. They are just two types of statements that are used in different scenarios.

But it cannot be called NMS. The critical point is that it cannot be used across vendors.

Yes. If I use Huawei devices all over the Internet

Huawei OMC can be called NMS

This is impossible.

Hahahaha

Not necessarily

All Telecom NMS must be a multi-vendor Concept

For example, a 3G core network may use a vendor, where the number of users is small.

NMS is only a management function and domain management issue, and has nothing to do with the manufacturer

That's just OMC.

NMS manages core networks, wireless networks, and service networks.

OMC, EMS, and NMS are not opposite.

It's not that OMC is definitely not NMS

Different starting points

I mean, OMC is so powerful that it cannot be called NMS.

Academic Debate

OMC now refers to the network management system of a specific manufacturer. As for whether the network management system only manages the network element layer or can be managed to the network layer, it is not necessarily

The starting point of EMS and NMS is the management layer.

Therefore, the two concepts have different starting points, not a latitude concept.

The old Network Administrator spoke up.

Incomparable

Listen to the small network manager ..

Huang Gong, let's talk about it. Old Network Manager, hahahahaha

Manufacturer OMC, manufacturer EMS, is probably a thing?

Different key points,

OMC mainly targets devices and NMS targets networks

OMC is now also oriented to the network

It's just the network of your own manufacturer.

It's not for other manufacturers.

So can you tell us it's not NMS?

Previously, OMC was relatively mentally retarded, so the previous OMC = EMS

The OMC manages the network in minutes. You can ignore it or not, but NMS is a matter in which it is divided. If it does not manage the network, it cannot be called NMS.

OMC originally targets a certain point. The NMS object is a region.

But now it's different.

No one in your name is allowed to manage the network, but not in your name.

In general, OMC = EMS, but in fact the current OMC> EMS

I mean, OMC and (EMS, NMS) have different latitudes.

Generally referred to as OMC

However, when talking about the management layer, we often use EMS (Management Network meta layer) and NMS (Management Network Layer)

Used in different scenarios

Select as needed, large

Tom understands it right. Previously, OMC = EMS

Today's discussion is good. I want to post it to my blog.
 

But now OMC and NMS are similar.

There is also an ENMS name

Siemens 3g omc can even connect to different manufacturers

 

 

 

The Network Element layer network management system directly targets the Network Element device interface to complete the collection of network element configuration and Network Element status, faults, alarms, and other information.

Network-layer network management system for network-wide monitoring and analysis, functions include network topology monitoring and operations, network-wide resource collection and analysis, network-wide fault alerts and Handling Based on topology and resource data, network-wide configuration information collection and configuration distribution, and end-to-end Network performance monitoring and analysis, traffic flow and traffic distribution monitoring and analysis, route analysis and route control.

EMS is slow. Do not call EMS NMS (You are slow)

Also called EMS
Slow!

What is NMS and EMS network management software?
