Title: Analysing network monitoring systems and objects for a telecommunications company
Subject: Computer Science
Level: Basic
Description: Cellip AB is a company that provides telecommunication solutions to companies and homes. Some of the services they provide are: IP-centrix, LYNC, skype-for-business and SIP-trunk.The company is an Internet Telephony Service Provider (ITSP), meaning they provide telephone services over the Internet Protocol (IP). Some of the company’s services replace the old-fashioned PBX (Private Branch Exchange) phone systems by integrating the communication into IP and software. LYNC and skype-for-business are partly a software-based IP-PBX.

The main office of the company is in Stockholm and from there they provide solutions that are based on modern technology, contributing to cheap and innovative communication applications to many companies throughout Sweden. Microsoft awarded Cellip two years in a row as the year’s voice partner, 2013 and 2014.

Cellips services have certain demands as their services are used in real-time. Faults in communication between users that are using their services could lead unacceptable quality. To keep the services pre-emptively from failing and to alarm them quickly if something fails, the company have implemented a monitoring solution. This monitoring solution is divided into subsystems that monitor different platforms. With this deployed strategy, the management of various services are inefficient as the network manager must go to each of these subsystems to check for valuable data. The company haven’t done any proper analysis as to which objects that are of importance to monitor. The objects that are being monitored are for the most part automatized, not taking the unique environment into consideration. The company lacks a network environment monitor strategy.

Today, the company is using a Nagios system to monitor their Linux platforms and an Azure system to monitor their Windows platforms. Cellip is looking for a monitoring system that can monitor a multi-server-platform environment and at the same time upgrade their outdated Nagios system.

In addition to finding a single monitoring system for both server-platforms, the company wants an evaluation to be done on which objects that are important to monitor on their servers. The actions to be taken on these objects is already decided. Currently, the actions taken on objects are by sending a notification in form of a text message and a mail to the one(s) responsible of monitoring the servers - the same notification system will be used for the new monitoring system as well.

The company is also looking for a cloud-solution to their monitoring system. With a cloud-based NMS (Network Management Station) the company don’t need to provide a physical location for the NMS. This means that the company don’t have to fulfil the needs that comes with physical server deployment.

Lastly, the company wants to create some form of map over the health status on their servers. By creating a real-time network weathermap, engineers can get a better “whole-view” of the servers’ health instead of inspecting separate graphs presented by a network monitoring system.

An interesting aspect in the research to be conducted is if companies that provide telecommunication solutions have special needs when it comes to monitoring their servers and services.
