All you need is a way to connect them, like an Ethernet cable or a Wi-Fi router. When the server receives the client request, it lookouts for the requested data and send it back with the reply.
Scalability In all likelihood, the most compelling argument in favor of peer-to-peer networks is their robustness. As we are all aware, many of the calls today are being initiated via presence lists.
Each computer acts as both the client and the server, communicating directly with the other computers. Peer-to-Peer network has the advantage over client-server that the server is not bottlenecked as the services are provided by the several nodes distributed in a peer-to-peer system.
Why is the growth of peer-to-peer VoIP being attributed for the most part to residential calling? The server contains a list of usernames and passwords and a user is only allowed to access the network only if they provide a valid username and a password to the server.
Has a silver bullet been found?
In a peer to peer network, resources are shared between peers without any central coordination by a server. A result of this architecture is that any number of nodes can be down and the end-to-end communication will still proceed unhindered.
Based on the Skype phenomenon, it would appear that, while most residential users afford this trust readily, corporate and enterprise users are more skeptical and have yet to take this leap of faith in large numbers.
Specifically, we would like to look at: The resources of the computers in the network can become overburdened as they have to support not only the workstation user, but also the requests from network users. In the client-server model, the server provides services to the client.
Further, client-server systems require central file server and they are expensive to implement than peer to peer systems. Call teardown is the process of hanging up the phone and releasing any resources that may have been associated with the call.
A server is actually a host that is running one or more server programs, which share their resources with the clients. However, in peer-to-peer, each peer can provide services and can also request for the services.

Also, many node users are not happy to share their bandwidth with others during critical times of the day. Off-Net Peering Complexity Earlier, we spoke of the call setup stage being comprised of a number of steps.
Given this scalable and robust architecture the questions that beg to be asked are why is the client-server model still around?
The node providing the requested service will respond to the node making the request. Device Mobility This somewhat orthogonal issue may yet prove to be the toughest challenge to the peer-to-peer model.
Proponents of the peer-to-peer approach cite its reduced infrastructure costs as a compelling argument for its superiority. When a user wakes up, this new state must be propagated to all his friends regardless of their online status.
It is easier to upgrade software applications and files because they are held on one single computer. In peer to peer architecture, tasks or workloads are partitioned between peers and these peers are said to form a peer to peer network.
Why have many corporate and enterprise users to date resisted the temptation of peer-to-peer communications? Peer to peer systems implement an abstract overlay network at the application layer on top of the physical network topology.
Here, Server is a powerful system that stores the data or information in it. What is Client Server? In the client-server model, data is stored on a centralized server whereas, in peer-to-peer each peer has its own data.
Relay of media via the end user is far less optimal than that of corresponding client-server approach. If the presence list is fixed to a device and not stored on a server somewhere, how do I take it with me?
Video of the Day Disadvantages and Limitations Peer-to-peer networks are typically less secure than a client-server network because security is handled by the individual computers, not on the network as a whole.
Therefore, selecting one over the other is dependent on the environment that you need to implement.Compare and Discern the Clear Difference Between Any Similar Things. What is the difference between Client-Server and Peer to Peer Network Architectures?
The main difference between client-server and peer to peer systems is that in the client-server architecture, there are designated clients that request for services and servers that.
Client server network. 3. Client server properties Comparison. 7.
Comparison of Client-Server and Peer-Peer. Client-Server. Peer-Peer.
Complex to set up: Simple to set up: Requires technical expertise to set up and maintain: Needs basic technical skills: Server present: No server present, each computer is a 'peer' of the others: Centralised.
The main difference between the Client-Server and Peer-to-Peer network model is that in Client-Server model, the data management is centralised whereas, in Peer-to-Peer each user has its own data and applications. Further, we will discuss some more differences between Client-Server and Peer-to-Peer network model with the help of comparison.
The traditional client-server model relies on designated network components for call setup and possible media relay, while the peer-to-peer model takes advantage of a user network consisting of nodes or machines running a common application.

GRAB THE BEST PAPER Extract of sample Compare and contrast a peer-to-peer and client server networks.
Peer-to-Peer Networks In contrast to client-server networks there is no dedicated server in peer-to-peer architecture. Thus each computer in such a network is part server and part client. This means that each computer on the network is free to share its own resources.Download
