IONOS NMS by SAGEM
 

1. INTRODUCTION

Network Management has to bring to the Customers the most global view of their network. It is becoming a key to successful use of large telecommunication networks. By ensuring that critical service information is always available, Network Management Platforms are becoming powerful tools to evaluate the real time service level offered to the users. They also have to drive the operators on reductions in operational costs.

IONOS NMS is the Network Management Platform designed by SAGEM SA to provide Network Element configuration, real time alarm monitoring, centralised access to all troubleshooting and Network Management functions for all SAGEM products. SDH products but also DWDM, SHDSL, FMX, Microwaves and other SAGEM equipment.

It has been designed such as :
• to offer to the customers, carriers and private companies the best service level with automated supervision
• to provision Services (Ethernet point to point for example, VLAN applications)
• to reduce the required skills of the operator personal by improving the management of network services
• to follow the next expansion of the customer’s network with a scalable architecture using truly distributed , client-server technology
• to facilitate the integration into the customer’s own management platform by integrating open interfaces

The global structure of IONOS NMS is given below :

1.1. PRODUCT OVERVIEW

Ease of use

IONOS NMS is a graphical, end-to-end network management application for configuring,
monitoring and controlling a SAGEM network infrastructure equipment.
With a comprehensive suite of Network Management tools, the operator can manage
equipment, network links and services through a very intuitive graphical user interface : “Drag and drop your organisation on the NMS screen”.

Scalability

Available on Windows XP and UNIX environment, IONOS NMS may run on commercial workstations and is fully scalable over a wide range of platforms with different computing power. Moreover, the client-server architecture is modular to allow distribution on computernetworks. IONOS NMS is based on advanced technologies (Object Oriented Conception,Relational Data Base, Java portability, Web technology, SNMP manager, HTTP servers) topropose a modular and scalable management platform, with a distributed hardware andsoftware architecture. This allows optimal cost effective fit for several sizes of managednetwork.

Persistency
The relational database-driven architecture warranties the flexibility and the global performance of the system. The MIB persistency is based on a Data Base Management
System (ORACLE for instance).

1.2. Data Communication Network
IONOS NMS is connected to the management port of a specific NE : the « gateway NE », via an Ethernet link, locally or remotely trough an IP network.
Inside SDH Networks, management information are carried on DCC bytes into STM-n frame overhead data or in a dedicated VC-12 in case of heterogeneous networks. The NE gateway ,and all NE in the network, realise a routing function (RIP or OSPF).
Inside TDM networks, management information are carried on dedicated bits of TS0 of the E1 frame or on dedicated bytes.


1.2. MANAGED NETWORKS AND PRODUCTS

IONOS-NMS is an homogenous and efficient solution for networks integrating numerous
SAGEM products :
• Any SDH network with SAGEM ADR range : FOT 155C, ADR 155 C, ADR 2500C, ADR2500eXtra, ADR155e, ADR155CPE, ADR10000
• SAGEM FSP2000 DWDM products
• Any TDM network with SAGEM FMX multiplexers
• Any MicroWaves network integrating SAGEM Link equipment – either PDH SAGEM Link F and SDH SAGEM Link A
• SAGEM TV transmitters and transposers


IONOS NMS has been designed to manage all SAGEM equipment.

2. IONOS NMS ARCHITECTURE

2.1. GLOBAL ARCHITECTURE
The general architecture is built on a client-server architecture: the various clients can be
installed on several physical machines connected to the same server.
The interface between the network element (NE equipment) and IONOS-NMS uses the
SNMP V1 protocol to send the alarm messages and to configure the end-to-end trails
(« provisioning »).
This interface also uses the HTTP protocol to configure the equipment (NE integrating an on-card HTTP server).
The management data are stored on the server.


• The interface between the NEs and IONOS NMS is realised trough SNMP V1 protocol concerning the alarms management and end-to-end configuration (provisioning).
• The interface is also realised trough HTTP protocol for the NE configuration.
• Data are stored in a data base on the servers

2.2. SOFTWARE ARCHITECTURE
IONOS-NMS is built on software modules implementing independent functional blocks
developed in JAVA: each block only processes a function subset of the complete
software.
IONOS-NMS is software environment which supplies:
• an SNMP interface.
• base services on which the main functions of the network elements manager are
based (alarms, logs, etc.)
• a Client application (MCP) based on use of Java Beans and providing the graphic interface elements (topology, etc.)


The IONOS-NMS platform contains a Network element manager and a Network manager.

2.3. HARDWARE ARCHITECTURE

- Server and Client machines

The Client Applications run on a PC whereas the Server Application run either on a PC or on a UNIX platform depending on performances required by the network and reliability
required by the customer.
For small networks, the Client Application can be run on the same PC platform as the server, in stand-alone mode.
The hardware platform thus remains flexible, open-ended and modular in terms of hard
disk drive, RAM and computing power in order to grow with the system, which entirely
depends on the number of network elements to be managed.

3. IONOS NMS GENERAL FEATURES

3.1. GRAPHIC USER INTERFACE (GUI) FUNCTIONS

Thanks to GUI (Graphic User Interface) the operator may :
• Copy & paste, drag & drop with mouse , rename resources
• Call contextual menus associated to resources
• Navigate between synoptic and configuration windows, navigate between alarms and synoptic window
• Have Network hierarchical views with a “Windows Explorer” look
• Move an element (equipment or sub-network) without removing links with other elements
• Disable or enable an Audio alarm
• See only one line per alarm (start, end, acknowledgement)
• Customise the colours (look and feel and icons)
• Ask for a Screen printing in all windows (print hidden parts of scrolled windows)
• Call a Help on line
• Add a Map as background image
• Multi-languages user GUI interface

3.2. SECURITY MANAGEMENT

3.2.1 Definition

The Management System provides functions to the operator in order to manage the security of the Management System itself, as well as the NEs, exploiting the system mechanisms and the database facilities.

3.2.2 Functions

Security management performs the following functions:
- Management of users ( with ID and access password)
- Log for user connection

3.2.2.1 Users Identification and password

Every user has to identify himself ( user ID and password) before giving him access to any system function. Every log, unlog and user ID is stored in a user log file.
By default, the following profiles are configured :
• Administrator : all rights on all functions.
• Operator : he may create and remove equipment.
• Observer : he may only consult and acknowledge alarms.

3.2.2.2 Activity Log

Operator activity is stored in a log file with the given parameters :
• Activity type
• Activity result (parameter old and new values)
• User ID
• date and time
The log file may be read, filtered and sorted with the stored parameters by administrator users only.

3.2.2.3 Conflicts resolution between local and centralised managers

The concurrent access is free in “read mode”. At the contrary, “write mode” access is given to the first connected user.
The other users are given a busy state message.

3.3. ADMINISTRATIVE FUNCTIONS

The following administrative functions are available:
• Backup / restore of management system database (command line)
• Backup / restore of management system database (GUI command)

3.4. USER MANAGEMENT

User administration is performed using the Admin View window.
This window enables:
???creation of new profiles, new groups and new users.
???operations on the profiles (add, delete, copy/cut, display and modify properties).
???operations on the groups (add, delete, copy/cut, display and modify properties).
???operations on the users (add, delete, copy/cut, display and modify properties).
???listing the network domains and their associated groups.

4. NETWORK MANAGEMENT FEATURES

4.1. CONFIGURATION MANAGEMENT
4.1.1 Definition
Configuration Management provides functions to identify, check, get and set data of the
managed resources.
At network level, Configuration management performs Provisioning, Monitor and control the status, Data and software management.
Configuration management is realised by choosing a NE on the network map and doubleclicking its icon. An HTTP session is then realised with the NE from the HTTP server embedded in the NE. The management windows and menus are particular for each equipment.

4.1.2 Functions
Configuration management performs the following generic functions:
• Definition of the network hierarchy (sub-network concept)
• Configuration of “tributary to tributary” trails
• Management of trail activation state (reserved or activated)
• Configuration of virtual elements in order to manage equipment from other manufacturers
• NE inventory discovery, NE audit, NE configuration misalignment automatic detection, NE inventory alignment, NE configuration reactivation, NE date synchronisation

4.2. FAULT MANAGEMENT
4.2.1 Definition
Fault management ensures that the deterioration in operating characteristic of the NEs caused by one or a set of abnormal conditions is kept to a minimum. Fault management ensures that the NEs faults are reported on network trails.
In order to do this, EM receives reports of alarms from the NEs. In general terms, EM is able to verify the NE accessibility by a polling mechanism, to supervise the access network NEs to detect the occurrence of abnormal condition and to record the existence of an abnormal condition

4.2.2 Functions
Fault management performs the following functions:
• Propagation of alarms occurred on a trail
• Management of protection mechanism
• Event correlation on trail

But also:
-Events supervision
-
Alarm re-alignment (from NE)
- Alarm log
- Alarm display
- Alarm real time monitoring
- Coloured alarm animation of icons
- Alarm synthesis window
- Event log
- Logs exportation
- Alarms acknowledge and clearing

4.2.2.1 Events Supervision
Equipment access is controlled periodically with a polling mechanism (configurable polling interval) to check :
??Equipment accessibility,
??Equipment status,
??Equipment de-alignment between the current configuration and the configuration in the
platform data,
??Eventual alarms loss.
Any condition change sends a notification and a graphical change on the network map.

4.2.2.2 Alarms Re-align function
This re-align function is automatically realised by polling the NEs status. So, every time a
connection is cut and established, the system searches for all existing alarms inside the NE and
update the network status.
4.2.2.3 Log function

The log function receives all alarms and events from supervision function or directly from the NEs. Filters and thresholds may be set in the NE before logging such events or alarms regarding the equipment.

4.2.2.4 Display function
The display function manages all kind of screen alarms displays, current log files and historical log files.
Generally, alarms are depicted with the following parameters :
- Alarm ID ,
- Alarm type ( communication, service quality, environment,…)
- Origin of the failure
- Alarm severity (major, minor, unknown)
- time
- alarm status (acknowledged, cleared,…)
Real Time Current alarms management
The manager monitors all alarms and events coming from all monitored NEs. The operator may enable or disable this monitoring on any NE. Every incoming alarm is immediately showed in a scrolling window, called the current alarms log.

Fault View
The alarms may be filtered with the following criteria :
- Resource ID
- Domain limitation
- Alarm type
- Severity
- Origin of the failure

The operator may acknowledge or clear an alarm. This action is recorded in the operator log file.
Synthetic alarm window
A synthetic alarms window gives to the operator a global view of the alarms in the network. He knows the number of active alarms.
Topology view animation
Icons depicting the NEs of the network are given a colour regarding their alarm status.
Conventional colours have been used : green colour means NEs without any fault (or with a warning fault), yellow colour means a minor alarm and red colour means major alarm.
Historical logs
This logs contain the complete list of past events, alarms and their characteristics : arrival time, status change and remove. Alarms may be filtered on the screen or printed by selecting any parameters combination :
- status
- severity , type
- date and time
- origin
- equipment list in a given domain

Fault Log

The results may be shown on the screen, printed or exported in excel format. The size of the file is configurable, depending on the disk size.
