  32. Analysis Summary Network Management and Traffic Analysis for Wireless MAN

  33. Network Management and Traffic Analysis for Wireless MAN Closing Remarks Conclusions Future Works

  34. Conclusions • The NMS had been designed, implemented, and deployed successfully. • The monitoring procedure was done on Ethernet interface using the objects of MIB-II standard. • The response time in notifying the network manager much depends on wireless link quality and the traffic intensity. • Different QoS class and traffic intensity generated different traffic behavior and self-similarity degree. Network Management and Traffic Analysis for Wireless MAN

  35. Future Works • Continuing the incremental sequence to NMS Development. • Defining additional features to support more functionality into NMS system, e.g. providing statistical analysis • Integrating the NMS with another system, e.g. developing Java application client. • Developing J2ME application is also possible for operation on mobile device. • Establishing additional research on self-similar model towards WiMAX QoS. • Collecting more rigorous data to get more convincing result. • Repeatable analysis and measurement once the WiMAX MIB interface is available.
