PEER TO PEER NETWORK



A network of personal computers, each of which acts as both clientand sever, so that each can exchange files and email directly withevery other computer on the network. Each computer can accessany of the others, although access can be restricted to those files

that a computer's user chooses to make available. Peer-to-peernetworks are less expensive than client/server networks but lessefficient when large amounts of data need to be exchanged.

What is P2P Network



1. Cost sharing/reduction.

2. � Resource aggregation (improved

performance) and interoperability

3. � Improved scalability/reliability.4. � Increased autonomy.

5. � Anonymity/privacy.

Goals



1.Decentralization

2. Scalability

3. Anonymity

4. Multicasting.

5. Spoofing the sender·s address.6. Identity Spoofing

CHARACTERISTICS



Peer-To-Peer networks are designed for limited number computers, it willstart creating issues when exceed 15 number of computers

High security levels can not be achieved using p2p networks, so if organization have concerns with security p2p will not be that great.

Organizational growth will outgrow p2p networks; it will not supportgrowing number of computers when increased above fifteen.

Regular training is required for computer users of p2p network. p2pnetwork is control by computers and computers are controlled by human,small mistake by one of the user can hold the work for other users on same

p2p network.

Limitation of P2P networking model:





So, let·s get going. I assume you have Windows XP Professional infront of you. Note that the Windows XP Home Edition does not

support this peer to peer network functionality.

Click Start, Control Panel, Network Connections.

Select the Set up a home or small office network link under

Network Tasks on the left side.The Network Setup Wizard screen will appear. Click Next.

Steps for Peer to Peer Network



The ³Before you continue´ screen appears listing the steps that will be completed. Click

the checklist for creating a network link. The result is shown in the picture given below.

When you¶re done looking through it, go ahead and close that window.

Now, click Next on the ³Before you continue screen.´



If the wizard finds disconnected networking interfaces, you¶ll see the screen given below, entitled The Wizard

found disconnected network hardware. You¶ll need to connect the network interfaces or select the Ignore

disconnected network hardware checkbox to continue

. Once you¶ve resolved this problem, click Next.

Make sure you resolve the network interface connectivity before proceeding to a connection method.



The ³Select a connection method´ screen appears. Here you will select from three connection options (see

example in image below). Make your selection and click Next.

Note: For the first computer you set up (which typically acts as the ³mothership´ of the peer to peer network), you shouldclick ³This computer connects directly to the Internet´ radio button. For the computers that you set up thereafter (second,third, fourth, etc.), select the second radio button, which says that another computer is already hosting and managing the

Internet connection.



On the ³Select your Internet connection´ screen, select the network connection that relates to the Internet under

Connections and click Next. You must make a selection or the Next button will remain grayed out.



Configuring the Internet ConnectionYour computer has multiple connections, so this part is very important for both Internet

connectivity and firewall issues (see image below). Its here you begin to assist the wizard by

defining the ³inside´ network adapter (local area network) and the ³wild-side´ network adapter

(Internet connection). Make the appropriate selection and clickNext. In my case, I selected ³Let

me choose the connections to my network.´

Establishing the Routed Connection Between Local Computers and the Internet



Continuing with my example, because of the selection I made, the ³Select the connections to

bridge´ screen appears. This is shown in the picture below. Make the connection selection and

click Next.

Go ahead and select the network interface that applies to your local area network.



Complete the Computer description and Computer name fields on the ³Give this computer a

description and name screen´ (similar to the picture below) and click Next.



Complete the Workgroup name field on the ³Name your network´ screen and click Next. (See

picture below).



Review your settings on the ³Ready to apply your network settings´ screen and when everything is

set correctly, click Next.

Click Finish after the configuration process is completed.



You have now created the mothership machine on the peer to peer network.Next, you will configure a client computer (any other client computers you addto the peer network will be configured in a similar manner). This is easilyaccomplished by running the wizard on the other Windows XP Professionalcomputers and again, in step 8 (see image #3), you will select the second radio button.You would then complete the screens that follow asking for network

naming information.
