Though far from a perfect solution, streaming video technology is becoming more powerful all the time. Streaming video allows the user to view video over the Internet as it downloads, instead of waiting until the entire file is downloaded to the computer. To get the average response time is 0.5 sec on data rate on WAN is by using the 1967750Mbps (1.87659 Terabyte) as shown in Fig1. The web page response time is increase 0.4 as compare to the default data rate of WAN link on web response time 0.3 as shown in Fig 2. Advance Scenario 2 To analyze the traffic, we change the value on small company LAN with two switches over WAN. Different users have difference requirement of music server streaming so we use different values of different users. FTP Download Response time and Web Application Response time with comparison Two switch WAN and Two switch WAN Demand Object. Student Name: Sheraz Salim Student ID: 20388626 2 as showing in Fig 3. A significant result shown when streaming started on the network, application start intense bandwidth of network. Nevertheless using T1 WAN data link rate seems slow connection. Module: CO4506 Wired and Wireless 1GBbps is not showing much big difference however using 100MBps cable worthwhile on this network as shown in table2,3 and Fig5. Table2 HTTP Application Response Time (average time) Cable Data Transfer Rate(seconds) 10MBps 0.45 100MBps 0.44 1GBbps 0.44 Fig4 LAN failed Router and LAN failed WAN link in Fig3 we analyse the router fail and WAN link fails. When router goes down the ARP table of network delete the router table entry. So all traffic is deliver to the other router which is connected to WAN. On other hand when WAN Link goes down the network traffic request the data from router and router ARP table is in list of network machines. But however the router is not connected to WAN link so traffic delay and that s what show in the fig4 is.http://appfreshy.com/honda-odyssey-factory-service-manual-pdf.xml

Advance Scenario 4 and 5 upgrading to 100MBbps links will speed up the transfer rate of data as network is implemented 10MBbps cable. Thus upgrading cable to Student Name: Sheraz Salim Fig5 10MBps,100MBps,1GBbps Table3 FTP Download Response Time (average time) Cable Data Transfer Rate(seconds) 10MBps 0.60 100MBps 0.62 1GBbps 0.60 The analysis show there is no use to upgrade the cable on network. The results are not showing difference. Consider cable upgrade in this situation if network grow in future. Challenge As company is double its computing equipment in 2 years, we double the traffic on the network topology and the simulaltion WAN result generated as show in fig6 Student ID: 20388626 3 Module: CO4506 Wired and Wireless higher use. Company can use T1 line which will give them a saving of money. As a network consultant my recommendation will be to put a firewall so block illegal access for staff. Fig6. WAN data rate using T1. The result show that network is consuming a lot of bandwidth on each side. As WAN link2 reduce to 37.5 and WAN link1 reduce to 50. To tackle this problem we shall use T3 line instead of T1 line. By using T3 line the result are show in fig7 Fig7. WAN data rate using T3. Which show a significant improvement. Conclusion The lab give a view of load balancing by putting two router using EIRG, to performed it better for network usage. In challenge scenario where company double its equipment we put T3 line. Instead of putting T3 line we could put firewall router and block illegal access for the staff. By doing this it will give a company to save a money paying for Student Name: Sheraz Salim Reference (1) Networks Design and Management, second edition. StevenT.

The first two parts are a short installation manual and an introduction to OPNET. After that there are 10 Labs that bring into practice different networking technologies. Lab 1: ICMP Ping, we study Ping traces and link failures. Lab 2: Subnetting and OSI Model, we study tiers 1,2 and 3 of the OSI model, and the Packet Analyzer tool to observe TCP connections. Lab 3: Firewalls, we begin with proxies and firewalls. We will deny multimedia traffic with a proxy, and study the link usage performance. Lab 4: RIP explains the RIP routing protocol, and how to create timed link failures and recoveries. Lab 5: OSPF compares RIP. We study areas and Load Balancing. Lab 6: VPN studies secure non-local connections.

Although it can control the ingoing and outgoing traffic, the most common usage of firewalls is to control the ingoing traffic. Note that Firewalls do not provide any security from internal attacks. There are two general policies: a) accept all packets except for a finite set of cases, and b) deny all traffic except for a finite set of cases. Case b is more difficult to implement, but it is generally more recommendable. Each packet reaching the device will lookup the filtering rules and stop at the first match, and after that will decide the decision of either denying or accepting the traffic. A default policy is always set. Proxies (Application Gateways) They behave as Application-level retransmission devices. Network users establish a communication with the proxy, thus dividing the source-destination connection in two independent connections (source-firewall and firewall-destination). The proxy server manages the requested connections. This technology has a slower performance that network firewalling because it is working on the upmost OSI layer. It is usual to use both firewalls at the same time. Cache Proxies are a popular way to increase performance by storing the data the gateway transmits into the firewall, so it is not necessary to lookup in the Internet for the same data next time another computer requests it. -2- At the same time, some company guys are using illegal multimedia downloading, and so slowing the Internet link performance.

The company is requesting to set up a Firewall to avoid multimedia traffic in order to decrease the mean database access time to a 1 sec threshold. All we need to modify are the Application Definitions. Delete all the applications that may be defined (tip: set rows: 0), and create 4 applications as seen in the picture (set rows: 4 and edit the four applications as seen in the picture L3.3). First step is to change the Name:, HTTP, DB and MusicAndVideo. Change the application load afterwards: -4- Permits (Low Load) These two applications can be configured automatically by double-clicking on the corresponding fields. To configure MusicAndVideo and DB, double-click on the fields of picture L3.3 marked with the (.) symbol: DB Database, MusicAndVideo Voice, and then set the values as in pictures L3.4 and L3.5. L3.4 and L3.5 Configuring the application traffic -5- The hierarchies that are not deployed on pictures use default values. Applications can be appended to profiles adding new rows to the Applications field, and setting the field Name on every row 0 of the Applications branch. We can also modify the Start Time of all Applications and Profiles (packet reception distribution), the Operation Mode, and the Repetition Pattern. 4. Setting up the Firewall: This first scenario permits the voice traffic. Picture L3.7 shows the main options to be configured in the router. The attributes to modify are the following: Address and Subnet Mask: AutoAddressed on all rows of IP Routing Parameters Interface Information and IP Routing Parameters Loopback Interfaces. We need to set up the routing protocol OSPF: OSPF Parameters Interface Information row 0 and row 1 (the unique router interfaces) Type: Broadcast. Set Point to Point to the remainder (rows 2 9). Proxy Server Information row 6 (corresponds to Application Remote Login, necessary for Database access) Proxy Server Deployed: Yes, this ensures that database traffic has the right to pass.

-7- We have to modify the Application: Supported Services, by setting the parameters as seen in the picture below (we need to set rows: 1 to accept MusicAndVideo). Leave the remainder options with default values. -8- Use the values from picture L3.10 (non-deployed branches use default parameters). This configuration will use 250 workstations for each and every LAN (Number of Workstations), 5 of them will be doing web browsing, 5 will be using, 50 attempting to connect to the database and 9 using MusicAndVideoServers illegally (Application: Supported Profiles). When finished, click on OK. L3.10 Assigning profiles to workstations at LAN 1 LAN 2 will be configured with the same values.Set Data Rate: T1. 9. Configuring the simulation statistics: The performance and throughput statistic parameters can give interesting information, as well as the DB Query delay: Right click on the Internet-Firewall link Choose Individual Statistics and mark the checkboxes as in picture L3.11. Click OK. L3.11 Internet-Firewall link statistics In order to choose the DB Query simulation statistics, right click anywhere else in the grid except of a node, select Choose Individual Statistics and check the fields as in picture L3.12. Click OK. L3.12 Global statistics -10-. Don t start the simulation yet., set Creating the second scenario The second scenario is a duplicate of the first, but with some router rules avoiding particular packets from and to music and data services. Later on we will see how this decreases the internet link throughput and database access time fair enough below the 1 second limit. From the Project Editor, Scenarios Duplicate Scenario. Rename the new scenario: WithFirewall, and right click on Firewall and Edit Attributes. Leave all the values as they are, except the Proxy Server Information row 8 (Application Voice data), using Proxy Server Deployed:No. Results Analysis Run all the simulations of the scenarios, and take a look at the graphics: 1.

At the Project Editor, Scenarios Manage Scenarios.Now we can browse in all the general statistics we programmed before in the left side tree. Check out that Overlaid Statistics, All Scenarios and average options are marked. L3.14 Compare Results Questions Q1 Compare the DB Query Response time (sec). Can you see a significant improvement when the firewall is implemented at the proxy. Do we respect the 1 sec threshold. How is the non-illegal applications effective bandwidth affected by the proxy. Q3 Compare the utilization of the same link. What changes do you appreciate? -12- The bandwidth was absolutely saturated. L3.16 Average point-to-point throughput of the link Q3 The main part of the network traffic was voice traffic, but what we didn t know is that this was saturating the Internet link capacity. When the proxy is on, the utilization reaches almost 0%. -13- We investigate the application performance We investigate application performance and capacity planning, by OPNET IT Guru s user-friendly interface with All Rights Reserved.

Manual software testing is the most primitive technique of all testing types and it helps to find critical bugs in the software application. Any new application must be manually tested before its testing can be automated. Manual Software Testing requires more effort but is necessary to check automation feasibility. Manual Testing concepts does not require knowledge of any testing tool. This makes Manual Testing imperative. In this Manual Testing tutorial for beginners, we cover all manual testing concepts and topics in detail. Click here if the video is not accessible Goal of Manual Testing The key concept of manual testing is to ensure that the application is error free and it is working in conformance to the specified functional requirements.

Test Suites or cases, are designed during the testing phase and should have 100% test coverage. It also makes sure that reported defects are fixed by developers and re-testing has been performed by testers on the fixed defects. Basically, this testing checks the quality of the system and delivers bug-free product to the customer. Types of Manual Testing: Manual Testing Concepts Below given diagram depicts Manual Testing Types. In fact, any type of software testing type can be executed both manually as well using an automation tool. Also, study the Application Under Test (AUT) if available. Draft Test cases that cover all the requirements mentioned in the documentation. Review and baseline the test cases with Team Lead, Client (as applicable) Execute the test cases on the AUT Report bugs. Once bugs are fixed, again execute the failing test cases to verify they pass. Myths of Manual Testing Following are few common myths and facts related to testing: Myth: Anyone can do manual testing Fact: Testing requires many skill sets Myth: Testing ensures 100% Defect free product Fact: Testing attempts to find as many defects as possible. Identifying all possible defects is impossible. Myth: Automated testing is more powerful than manual testing Fact: 100% test automation cannot be done. Manual Software Testing is also essential. Myth: Testing is easy Fact: Testing can be extremely challenging. Testing an application for possible use cases with minimum test cases requires high analytical skills. Manual Testing vs Automation Testing Manual Testing Automated Testing Manual testing requires human intervention for test execution. Automation Testing saves time, cost and manpower. Once recorded, it's easier to run an automated test suite Any type of application can be tested manually, certain testing types like ad-hoc and monkey testing are more suited for manual execution.

Automated testing is recommended only for stable systems and is mostly used for Regression Testing Manual testing can become repetitive and boring. The boring part of executing same test cases time and again is handled by automation software in Automation Testing. Manual testing is a vital part of user-friendly software development because humans are involved in testing software applications and end-users are also humans. They need to think and act with an End User perspective. Prev Report a Bug Next YOU MIGHT LIKE: Defect Tools MANTIS Bug Tracker Tutorial For Beginners What is Mantis Bug Tracker.
