Network Performance Tools For Network

In the past latency issues have derived primarily to out of date hardware or device drivers as opposed to a security breach. It is always a wise choice to update these configurations while running the appropriate operating system updates which may all be contributing factors. During the prerequisite stage of the survey the required information is gathered to develop an effective network survey which would alleviate resource constraint.

An alternative free network analyzer (Packet Sniffer) application available is Capsa it allows you to monitor network traffic, troubleshoot network issues and analyze packets. Teachers and students of network classes use it to demonstrate network

* Test the Data Rate values by doing a Flow Analysis. Look at the WAN Link Maximum Utilization. If the value is more than 50%. Increment the link Data Rates another 64,000 bps and do another Flow Analysis. When you have reached a Data Rate that shows a Flow Analysis Maximum Utilization % less than 50%, then leave the Data Rate at that value. [NOTE: It is faster to start at 320,000 bps and increase by 64,000 bps until you achieve the Flow Analysis Maximum Utilization % less than 50%]

To measure the performance I used Opsview monitoring solution to monitor both DNS and DHCP on Linux and Windows server. Some sample tools like ping, nslookup and traceroute can be used in Windows and Linux to measure the basic metrics for DNS and DHCP. TO have a real data we need to test inside a real network or with some means generate the amount of traffic near the real traffic to find our network and services' bottlenecks.

The Asus designed administration dashboard also allows the RT-N66U to be configured with a VPN for added security and privacy. There are several tools for diagnostics and monitoring as well for both optimization and security testing. Easy to read graphs and logs make tweaking and optimizing very intuitive. Any adjustment that affects the connection will clearly be displayed in real time. Traffic monitoring tools offer multiple views into how your bandwidth is being

The simplest way of using PuTTY is to fill in the host-name/IP and specify the port and connection type. The session can then be saved to be loaded at a later point.

Networks specialist use ping, trace route and tcpdump to find the exact bug rising factor in a system. But this type of monitoring techniques fails when the number of switches in the system increases. This type techniques fail in three reasons,

NOTE: Please write your answers to each question in a different color font to make this easier for the Professor to grade.

The NIC is an adapter that controls the exchange of information between the network and the user. In this company branches NIC’s are increasingly preinstalled and have the ability to automatically configure to match the speed of the network to which they are connected.

| Given a network topology of three or more routers with bandwidth designations, compare the metrics used during the route selection process and the resulting routing tables generated by the DUAL and SPF algorithms.

Monitored the network congestion in order to achieve the optimal performance out of a network infrastructure.

Understand why a certain link or network is not functioning as per performance specifications and will be able to successfully resolve them.

In this paper, we present the first data collection and profiling process result in our research framework. At this time, the second and the third data collection process are still on going. If it is completed, we will conduct the second part of our proposed experiment. The challenges is, we have to obtain an appropriate and enough RAW data that need more prolonged time for trial and error. We have to design scalable devices and computation architecture, since the system proposed will handle high volume of traffic at national level network. A comment and suggestion are welcome.
