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

manufacturer OMC, what is the difference with EMS
the manufacturers now have strong OMC, it can cover EMS and NMS
is the network element layer and network layer
EMS refers to the network element layer network management system, NMS is a network-layer network management system.
what is the difference between OMC and EMS?
OMC generally refers to the manufacturer's network management system for its own devices
EMS refers to the Network Element Layer 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 the Network Element Management and some network management functions.
I 've mentioned it, in the past, most OMC had to manage the network metadata of its own devices, but many of the current OMC can directly manage the network, it has risen to the NMS level.
therefore, OMC and EMS are not necessarily related, but they can only be called NMS in different scenarios.
, the critical point is that you cannot cross-vendor
, if I use Huawei devices all over the network
Huawei OMC can be called NMS
this situation is impossible
Hahahaha

not necessarily

all telecom NMS must be a multi-vendor concept
for example, a 3G core network may use a vendor, A small number of users

NMS is only a management function and domain management problem, it has nothing to do with the manufacturer
that is only OMC
NMS is responsible for core network, wireless network, and Business Network
OMC, EMS, and NMs not opposite
it doesn't mean that OMC is definitely not NMS
the starting point is different

I mean OMC is powerful, it cannot be referred to as NMS.
Academic Debate
what OMC means now is the network management system of a specific manufacturer, the network management system only manages the network element layer or the network layer, not necessarily
and the starting point of EMS and NMS is the management layer
so the two concepts have different starting points, it is not a latitude Dongdong
the old network manager sent a message
it cannot be compared
listen to the small network manager ..
Huang Gong, let's talk about the old network manager, Hahahaha

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 distribution, and end-to-end Network performance monitoring and analysis, traffic flow and traffic distribution monitoring and analysis, route analysis and route control.
