Welcome to NG-NetMS page

Opt/Net develops Next Gen Network Management System (NG-NetMS). This is a new web based end-to-end management tool. This project is nearly 14 years old and already proved to be indispensable tool for rapid data collection during audits and network infrastructure assessments.

This product provides near real-time visibility of the networks and ITC infrastructures and interconnected computing resources. It therefore can give participating operators end-to-end visibility of the cloud services and assists with quick localization of the root causes of potential incidents and outages. The main benefit of NG-NetMS tool is that it provides a central vantage point for end-to-end visibility into the security aspects of ICT services.

The NG-NetMS tool is running on Ubuntu 14.04 LTS. The typical deployment will need 4 cores and 4GBytes of RAM and at least 20GB of storage space. Also, NG-NetMS may be deployed on the dedicated server hardware if high performance and security required. But most efficient deployment for most of the users is with virtualized system into the cloud, which runs as one of the services.

NG-NetMS connects to the network routers and retrieves most current network topology parameters and automatically monitors addition and deletion of the devices and network links between them. It creates precise maps and is quick and efficient in collection of most complete information about the managed network's inventory, topology, map of IP address space and most important analysis of syslog events and SNMP alarms in near real time or from historical archives.

NG-NetMS is autonomous and dynamic system once it has been initiated and configured by the operator.

It consists of the following modules:

  • Network audit and Host polling modules
  • Device specific plugin modules
  • Central database
  • Event collector modules
  • Central database

Operators perform initialization and basic configuration of NG-NetMS via Web GUI. The system should be configured with authentication methods for entire managed domain. Also, the active feedback loop via syslog or SNMP from all managed hosts should be established.

All network devices should be configured to send syslog messages to the NG-NetMS via UDP or TCP network protocols, where these messages are received, processed and profiled by event collector modules in near real-time. All devices should contain logging and authentication configuration settings in order to be managed by NG-NetMS.

Inventory data

In order to discover and conduct complete inventory of the network infrastructure, NG-NetMS needs network topology information, which is created and maintained by the network routers. When networks and devices are configured or new devices are added, the infrastructure update cycle is triggered. The information is retrieved by NG-NetMS automatically, as soon as it receives messages that signify that infrastructure has changed. Then, NG-NetMS would initiate the network audit cycle and will rediscover the entire network topology. The network discovery may be partial or complete, depending on the type of change that took place.

Web GUI provides access to inventory information and has reporting capabilities. Information such as system software version and inventory of network interfaces, IP addresses and hardware is presented and could be exported in the number of reports.

IPv4 address tree provides information about IP addresses used and names of the interfaces that use them.

Historical events view

All discovered nodes are monitored continuously and periodic inventory of the complete network takes place. In real time all events from managed nodes are received by collectors and stored in the central database for archival purposes and analysis. The cumulative severity of the received messages may be plotted with Web GUI. This graphical representation helps with interpretation of the network and device activity and simplifies search for the root causes of different events.

The historical events view may be used for data analytics and search for the root causes of different events. Often, it helps with troubleshooting of different problems on the network and associated cloud services. It is particularly useful with detection of unauthorised tampering and for security monitoring.

Event analytics

Web GUI provides analytics for all collected events. There are two kinds of analytics reports available: (I) Cumulative severity of events per origin; and (II) Cumulative severity of events per facility.

It is easy to detect top sources of important events on the network based on these high level reports. Top sources could be investigated further once enough statistics becomes available through the historical and detailed event views.

NG-NetMS is scalable, flexible and modular and this is one of the reasons why it was selected for the visualisations of the largest networks. NG-NetMS is an Open Source project and is hosted on SourceForge. Opt/Net distributes most of its code under GPL3.0 and Apache licenses. This guarantees that NG-NetMS will benefit free software and research and education communities.

OPTOSS suite of products is being developed by Opt/Net under business incubation grant from European Space Agency (ESA). The commercial version of this product (OPTOSS Plus) relies on intellectual property developed by ESA in the area of advanced operations concepts. Opt/Net uses the ESA patens under R&D license agreement signed in 2014.
