...ISM4220 Business Data Communications Wireshark Lab 2 - Ethernet Part I. Capturing and analyzing Ethernet frames Let’s begin by capturing a set of Ethernet frames to study. Do the following: * First, clear your browser’s cache, and start it with a blank page. You may also want to close out all other browsers or web activities (It is important to do this step, so your Wireshark results won’t be overwhelming.) * Start up the Wireshark packet sniffer, and start a packet capture * Enter the following URL into your browser * http://lix1.myweb.usf.edu/about-usf-st-petersburg.htm * Stop Wireshark packet capture. * Save this capture with a name “Lab2 trace1 – yourlastname”, and the default file type should be .pcapng. You will need to submit this trace file, which shows your unique IP address and time stamp to prove the origin of your work. * Now locate the GET and OK packets that your computer communicated with the server that hosts the About USF St. Petersburg web page you’ve just visited. There could be multiple GET and OK packets, depending on the web activities going on. Make sure you get the right GET and OK packet using the info column of the Packet List. Create a lab report using MS Word, and answer the following questions. Q1. Provide the packet #s of the GET and OK packet. When you select the GET message in the packet list, you can see in the Packet Details (middle window), there are 5 section items * Frame ...

...Problem in the current web site of Midland bank The first problem that I found in Midland bank’s web site is that it’s a full of unnecessary images and the images sizes are very large. These images are just capturing the whole pages that create bad effect of the pages. For example , this picture doesn’t mean any effective sense here rather it just reduce the sizes of take proper information on the page. These pictures also increasing the page loaded time and it is hamper for any web site and customers feel disappointed when they browse the sites. Therefore, another problem are the site has lack of information. The information are not organized nicely and the site is not look like a standard financial service’s web site. Moreover, in this website meta description is not mention clearly. Visitors will be confused about the description while they visit the site. Then, in this site they don’t mention about reward program or the ranking position of their bank. Additionally, they just put their sponsor’s picture in their site but they don’ mention about their designation and other information about their sponsors that is very difficult to recognize their sponsors through visiting web site. In my observation another findings they don’t take important information in their site and the information that provided in their web site is not organized clearly. They uploaded many unnecessary pictures instead of providing important information. For example, this picture is not needed...

...Lab 5 Instructions Packet Tracer: Use of the TCP/IP Protocols and the OSI Model [Adapted from Cisco Networking Academy Network Fundamentals] Background: In Packet Tracer simulation mode, you may view detailed information about packets and how they are processed by networking devices. Common TCP/IP protocols are modeled in Packet Tracer, including DNS, HTTP, TFTP, DHCP, Telnet, TCP, UDP, ICMP, and IP. Packet Tracer uses a representation of the OSI model to display how these protocols are used by networking devices in creating and processing packets. The term “protocol data unit,” or PDU, is a generic description of what are known as segments at the transport layer, packets at the network layer, and frames at the data link layer. Help Files and Tutorials: From the pull down menu, choose Help->Contents. A web page will open. From the left frame, choose Operating Modes->Simulation Mode. If you are not already familiar with it, read about simulation mode. Realtime and Simulation Modes: In the far lower right of the PT interface is the toggle between Realtime and Simulation mode. PT always starts in Realtime mode, in which networking protocols operate with realistic timings. However, a powerful feature of Packet Tracer allows the user to "stop time" by switching to Simulation mode. In Simulation mode, packets are displayed as animated envelopes, time is event driven, and the user can step through networking events. To switch from Realtime mode to Simulation mode, click...
