Monitoring Network Quality - Using a TCP Analysis Approach |
| Synopsis: |
This project deals with the development of a monitoring system to
measure quality of service (QoS) on wireless networks.
The developed system carries out measurements without
sending packets on the network and therefore does not cause extra
traffic. Instead, the system analyses existing traffic on the network
by capturing packet with a sniffer, and performing a number of QoS
measurements. The results of these are stored in a Management
Information Base (MIB) and can be retrieved by a management system
through the SNMP protocol.
The developed system is based on an Object-Oriented Analyses and
Design (OOA/D). The system is defined in OOA and problem- and
application domains are analysed. The technical platform and the
architecture is presented in the OOD as well as system components and
their classes.
The monitoring system is implemented on a Linux operating system using
both C and Java programming languages. Java Native Interface is used in
communication between these two programming languages.
It became evident through testing that the system is able to measure
some of the parameters defined in the problem definition but not all.
The project is summarised and possible improvements are discussed in
the conclusion.
