Network collaboration tools give people the opportunity to work together efficiently and productively without the constraints of location or time zone. Collaborative tool types include document sharing, web meetings, and wikis.
In Part 1, you will identify collaboration tools that you currently use. You will also research some popular collaborative tools used today. In Part 2, you will work with Google Drive. In Part 3, you will investigate Conferencing and Web meeting tools and, in Part 4, you will work with wikis.

Required resources:

Resource required for this lab is device with internet access.

PART 1: Use collaboration tools

Step 1: List some collaboration tools that you currently use today
Step 2: List some reasons for using collaboration tools.
Part 2: Share Documents with Google Drive

In Part 2, you will explore the document sharing functions by using Google Drive to set up document sharing. Google Drive, formally Google Docs, is a web-based office suite and data storage service that allows users to create and edit documents online while collaborating in real-time with other users. Google Drive provides 5 GB of storage with every free Google account. You can purchase additional storage, if needed.

Step 1: Create a Google account. To use any of Google’s services, you must first create a Google account. This account can be used with any of Google’s services, including Gmail.

  1. Browse to www.google.com and click Sign in (located at the top-right corner of the web page).
  2. On the Google Accounts web page, if you already have a Google account, you can sign in now; otherwise, click SIGN UP.(located on top – right corner of the Google account page)
  3. On the Create a new Google Account web page, fill out the form to the right. The name you enter in the Choose your username field becomes the account name. It is not necessary to supply your mobile phone or current email address. You must agree to the Google Terms of Service and Privacy Policy before clicking Next step.
  4. The next webpage allows to add a profile photo if you would like. Click Next step to complete the account creation process.

Step 2: Create a new document.

  1. Sign in to Google using the access credentials you created in Step 1. Type http://drive.google.com in your browser and press Enter. This navigates you to Google Drive.
  2. Click the CREATE button to display a drop-down menu that allows you to select the type of document to create. Choose Document. The new document displays. Many of the functions of the Google editor work similarly to Microsoft Word.

Step 3: Share a Google document.

  1. After the blank Google document opens, you can share it with others by clicking the Share button (at the top-right corner of the web page).
  2. Name your new document, then click the Save button.
  3. Here on the Sharing settings web page, in the Add people text field, you can enter Google email names, email addresses, or groups with whom to share this document.
  4. As soon as you start entering information into the Add people box, the box provides more options. The Can edit drop-down menu allows you to choose the document privileges (Can edit, Can comment, and Can view) for the people you add. You can also specify how to notify these people of this document (Send a copy to myself or Paste the item itself into the email). Click Share & save.
  5. Click the Done button. This will navigate you back to the open document.
  6. All users with share privileges can view this document at the same time. Users with edit privileges can edit this document while others view it.
  7. If the document is being viewed by someone while you are in it, you can see who they are by clicking the other viewer(s) drop-down menu (in the upper-right corner of the document).

Step 4: Close a Google document. To close a Google document, move your cursor to the document name at the top of the screen and a left arrow will appear to the left of the name. Click that arrow to return to your Google Drive home page. The document is automatically saved. The new document will appear at the top of your documents list under My Drive.

Step 5: Additional Information Google has developed apps for PCs and Smart phones. For more information about Google Drive, go to http://drive.google.com. YouTube is also a viable source of Google Drive tutorials.

Part 3:

Part 3 of the lab is to explore conferencing and web settings Web meetings combine file and presentation sharing with voice, video, and desktop sharing. Cisco WebEx Meeting Centre is one of the leading web meeting products available today. In Part 3 of this lab, you will watch a video produced by Cisco that reviews the features contained within WebEx Meeting Centre. The video is located on YouTube at the following link: http://www.youtube.com/watch?v=fyaWHEF_aWg

Part 4:

Part 4 of this lab is to CREATE WIKI PAGES. “Wiki” is a Hawaiian-language word that means fast. In networking terms, a wiki is a web-based collaboration tool that permits almost anyone to immediately post information, files, or graphics to a common site for other users to read and modify. A wiki provides access to a home page that has a search tool to assist you in locating the articles that interest you. A wiki can be installed for the Internet community or behind a corporate firewall for employee use. The user not only reads wiki contents, but also participates by creating content within a web browser. Although many different wiki servers are available, the following common features have been formalized into every wiki:

  • Any web browser can be used to view or edit pages or create new content.
  • Edit and auto links are available to edit a page and automatically link pages. Text formatting is similar to creating an email.
  • A search engine is used for quick content location.
  • Access control can be set by the topic creator, defining who is permitted to edit content.
  • A wiki is a grouping of web pages with different collaboration groups.

In this part of the lab, you will use the Google account that you created in Part 2 and create a wiki page in Google Sites.
Step 1: Sign in to Google Sites.
Go to http://sites.google.com sign in using the Google account that you created in Part 2 of this lab.

Step 2: Click CREATE (on top left)
Step 3: Name your new wiki site.
In the Name your site field, type in a name for your new wiki site. You will need to come up with a unique name for your site that has not been used by any other Google user. Google also requires that you enter the code (displayed at the bottom of the screen) to prevent automated scripts, called web robots, from creating multiple sites. After you have entered your site name, click the CREATE button. If someone has used your site name already, you are prompted to enter another name. Also to type the code shown to create the site has an option for visually impaired person.

Step 4: Edit the look of your new wiki site.

  1. Google has provided templates for you to change the look of your new wiki site. Click the More dropdown menu on the top right of the webpage, and then click Manage site .A new page appears where you can edit your site.
  2. Click Themes at the bottom of the left sidebar under manage site option.
  3. Select a theme that appeals to you and click SAVE. Each theme has specific name you can choose accordingly.
  4. After you have saved your theme selection, click your site name under Manage Site.

Step 5: Update the Home page.

  1. The Home page is the first page that everyone sees when they come to your wiki site. You can edit the content of this page by clicking the edit button. From here, you can add text, pictures, or anything else to show on this page.
  2. Click Save after you makes your changes. This takes you out of page edit mode.

Step 6: Create a wiki page

  1. To create a new pages that you and your visitors can use to make posts, click the new page icon, which on the top right of your wiki home page
  2. In the Name your page field, enter a page name.
  3. Then move to Web Page drop-down menu and select Announcements. Google uses this term to indicate a wiki page.
  4. Click CREATE to create your new wiki page.
  5. Your new wiki page displays and has a New post menu option that allows information to be added to the page

Step 7: Share your web site.
A wiki site is not really a wiki site unless other people can contribute. There are a number of ways to share your new site. In this example, we will show you how to share your site to designated people who have G mail accounts.

  1. On your site click share on top left of your new page.
  2. Add a name, email address, or group who you grant access to this site.
  3. As soon as you start entering information into the Add people box, the box provides more options. Right to it there is a Can edit drop-down menu allows you to choose the document privileges (Can edit, Can comment, Can view) for the people you add. You can also specify how to notify these people of this document (Send a copy to myself or Paste the item itself into the email). Click Share & save.
  4. The Manage Site page displays the people who have access to your site. Click your site name to return to your home page.

Step 8: Provide the URL of your site.
You can provide your URL to your new site by adding your site name to the end of the Google site URL, as shown here: http://sites.google.com/site/ (site name).

Step 9: Find additional information.
You can find a quick overview of how a wiki works at http://www.youtube.com/watch?v=-dnL00TdmLY.

Other examples of wikis and their web sites include:

1.3.1.3 Lab -Mapping the Internet

Objectives

Part 1: Test Network Connectivity Using Ping
Part 2: Trace a Route to a Remote Server Using Windows Tracert
Part 3: Trace a Route to a Remote Server Using Web-Based and Software Tools
Part 4: Compare Traceroute Results

Background

Route tracing computer software is a utility that lists the networks data has to traverse from the users originating end device to a distant destination network.
This network tool is typically executed at the command line as:
tracert <destination network name or end device address> In Microsoft windows system 

 Or 
traceroute <destination network name or end device address>
In UNIX and similar systems.

Route tracing utilities allow a user to determine the path or routes as well as the delay across an IP network. Several tools exist to perform this function.
The traceroute (or tracert) tool is often used for network troubleshooting. By showing a list of routers traversed, it allows the user to identify the path taken to reach a particular destination on the network or across inter networks. Each router represents a point where one network connects to another network and through which the data packet was forwarded. The number of routers is known as the number of "hops" the data traveled from source to destination.

The displayed list can help identify data flow problems when trying to access a service such as a website. It can also be useful when performing tasks such as downloading data. If there are multiple websites (mirrors) available for the same data file, one can trace each mirror to get a good idea of which mirror would be the fastest to use.

Two trace routes between the same source and destination conducted some time apart may produce different results. This is due to the "meshed" nature of the interconnected networks that comprise the Internet and the Internet Protocols ability to select different pathways over which to send packets.

Command-line-based route tracing tools are usually embedded with the operating system of the end device.

Other tools, such as VisualRoute™, are proprietary programs that provide extra information. VisualRoute uses available online information to graphically display the route.

This lab assumes the installation of VisualRoute. If the computer you are using does not have VisualRoute installed, you can download the program using the following link:

http://www.visualroute.com/download.html

Scenario

Using an Internet connection, you will use three route tracing utilities to examine the Internet pathway to destination networks. This activity should be performed on a computer that has Internet access and access to the command line. First, you will use the Windows embedded tracert utility. Second, you will use a web-based traceroute tool (http://www.subnetonline.com/pages/network-tools/online- traceroute.php). Finally, you will use the VisualRoute traceroute program.

Required Resources

1 PC (Windows 7, Vista, or XP with Internet access)

Part 1: Test Network Connectivity Using Ping

Step 1: Determine whether the remote server is reachable. To trace the route to a distant network, the PC used must have a working connection to the Internet.

  1. The first tool we will use is ping. Ping is a tool used to test whether a host is reachable. A packet of information is sent to the remote host with instructions to reply. Your local PC measures whether a response is received to each packet, and how long it takes for those packets to cross the network. The name ping comes from active sonar technology in which a pulse of sound is sent underwater and bounced off of terrain or other ships.
  2. From your PC, click the Windows Start icon, type cmd in the Search programs and files box, and then press Enter.
  3. At the command-line prompt, type ping www.cisco.com.
  4. The first output line displays the Fully Qualified Domain Name (FQDN) e144.dscb.akamaiedge.net. This is followed by the IP address 23.1.48.170. Cisco hosts the same web content on different servers throughout the world (known as mirrors). Therefore, depending upon where you are geographically, the FQDN and the IP address will be different.
  5. From this portion of output:

Ping statistics for 23.2.128.170:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 224ms, Maximum = 234ms, Average = 227ms
Four pings were sent and a reply was received from each ping. Because each ping was responded to, there was 0% packet loss. On average, it took 227 ms (227 milliseconds) for the packets to cross the network. A millisecond is 1/1,000th of a second.
Streaming video and online games are two applications that suffer when there is packet loss, or a slow network connection. A more accurate determination of an Internet connection speed can be determined by sending 100 pings, instead of the default 4. Here is how to do that:
C:\>ping -n 100 www.cisco.com
And here is what the output from that looks like:
Ping statistics for 23.2.128.170:
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 140ms, Maximum = 720ms, Average = 256ms

  1. Now ping Regional Internet Registry (RIR) websites located in different parts of the world:

All these pings were run from a computer located in the Australia. What happens to the average ping time in milliseconds when data is traveling within the same continent (Australia) as compared to data from Australia traveling to different continents?
What is interesting about the pings that were sent to the European website?

Part 2: Trace a Route to a Remote Server Using Tracert

Step 1: Determine what route across the Internet traffic takes to the remote server.
Now that basic reach ability has been verified by using the ping tool, it is helpful to look more closely at each network segment that is crossed. To do this, the tracert tool will be used.

  1. At the command-line prompt, type tracert www.cisco.com.

C:\>tracert www.cisco.com
Tracing route to e144.dscb.akamaiedge.net [23.2.128.170]

Trace complete.

b. Save the tracert output in a text file as follows:
1) Click alt + space this opens the tab with options like restore, minimize move down select edit, in edit select mark.
2) Select all and choose edit > copy.
3) Open the Windows Notepad program: Windows Start icon > All Programs > Accessories > Notepad.
4) Paste the output into the notepad.
5) Choose File > Save As and save the Notepad file to your desktop as tracert1.txt.
c. Run tracert for each destination website and save the output in sequentially numbered files.
C:\>ping www.afrinic.net
C:\>ping www.licnic.net
d. Interpreting tracert outputs.

Routes traced can go through many hops and a number of different Internet Service Providers (ISPs), depending on the size of your ISP and the location of the source and destination hosts. Each “hop” represents a router. A router is a specialized type of computer used to direct traffic across the Internet. Imagine taking an automobile trip across several countries using many highways. At different points in the trip you come to a fork in the road in which you have the option to select from several different highways. Now further imagine that there is a device at each fork in the road that directs you to take the correct highway to your final destination. That is what a router does for packets on a network.

Because computers talk in numbers, rather than words, routers are uniquely identified using IP addresses (numbers with the format x.x.x.x). The tracert tool shows you what path through the network a packet of information takes to reach its final destination. The tracert tool also gives you an idea of how fast traffic is going on each segment of the network. Three packets are sent to each router in the path, and the return time is measured in milliseconds. Now use this information to analyze the tracert results to www.cisco.com. Below is the entire traceroute:

Trace complete.

Here is the breakdown Consider the first line of tracing route
1 <1 ms <1 ms <1 ms 192.168.100.13
Less than 1 milli second represents the time taken by packet to access the first router.
192.168.100.13 is the address of router on the computer home network
Consider the second line of tracing route
2 <1 ms <1 ms <1 ms dip-202-72-135-9.wa.westnet.com.au [202.72.135.9]
202.72.135.9 represent hop 2 POP router.
In the example output shown above, the tracert packets travel from the source PC to the local router default gateway (hop 1: 192.168.100.13) to the ISPs Point of Presence (POP) router (hop 2: 202.72.135.9). Every ISP has numerous POP routers. These POP routers are at the edge of the ISP’s network and are the means by which customers connect to the Internet. The packets travel along westnet network for two hops and then jump to a router that belongs to ii.net. This could mean that the packets have traveled to another ISP. This is significant because sometimes there is packet loss in the transition between ISPs, or sometimes one ISP is slower than another.

e. There is an Internet tool known as whois. The whois tool allows us to determine who owns a domain name. A web-based whois tool is found at http://whois.domaintools.com/.

To summarize, Internet traffic starts at a home PC and travels through the home router (hop 1). It then connects to the ISP and travels through its network (hops 2-7) until it arrives at the remote server (hop 8).This is a relatively unusual example in which there is only one ISP involved from start to finish. It is typical to have two or more ISP involved as displayed in the following examples.

f. Now examine an example that involves Internet traffic crossing multiple ISPs. Below is the tracert for www.afrinic.net:
