The independent dispute between the Client-Server and Peer-to-Peer network model is that in Client-Server model, the datum management is centralised whereas, in Peer-to-Peer each drug user has its own data and applications. far, we will discuss some more differences between Client-Server and Peer-to-Peer network model with the avail of comparison chart shown below, good have a look .
Content: Client-Server Vs Peer-to-Peer
Basis for ComapaisonClient-ServerPeer-to-Peer
Basic There is a specific server and specific clients connected to the server.Clients and server are not distinguished; each node act as client and server.
ServiceThe client request for service and server respond with the service.Each node can request for services and can also provide the services.
FocusSharing the information.Connectivity.
DataThe data is stored in a centralized server.Each peer has its own data.
ServerWhen several clients request for the services simultaneously, a server can get bottlenecked.As the services are provided by several servers distributed in the peer-to-peer system, a server in not bottlenecked.
Expense The client-server are expensive to implement.Peer-to-peer are less expensive to implement.
StabilityClient-Server is more stable and scalable.Peer-toPeer suffers if the number of peers increases in the system.
Definition of Client-Server
The Client-Server net model is widely used network mannequin. here, Server is a mighty system that stores the data or information in it. On the early hands, the Client is the machine which let the users entree the data on the outback server .
The system administrator manages the data on the waiter. The node machines and the server are connected through a network. It allows the clients to access data even if the client car and server are far apart from each other .
In Client-Server model, the customer march on the client machine sends the request to the server summons on the server car. When the server receives the client request, it lookouts for the requested data and send it back with the reply.
As all the services are provided by a centralized waiter, there may be chances of server getting bottlenecked, slowing down the efficiency of the organization .
Definition of Peer-to-Peer
Unlike Client-Server, the Peer-to-Peer model does not distinguish between node and server alternatively each node can either be a node or a waiter count on the whether the lymph node is requesting or providing the services. Each node is considered as a peer .
To become a part of peer-to-peer, a node must initially join the network. After joining it must start to provide services to and must request the services from other nodes in the peer-to-peer system. There are two ways to know which node provides which services ; they are as postdate :
- When a node enters the peer-to-peer system, it must register the services it will be providing, into a centralized lookup service on the network. When a node desires for any specific service it must contact centralized lookup services to check out which node will provide the desired services. Rest of the communication is done by the desiring node and the service providing node.
- A node desiring for the specific services must broadcast the request for services to all other nodes in the peer-to-peer system. The node providing the requested service will respond to the node making the request.
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 .
Key Differences Between Client-Server and Peer-to-Peer Network
- The key difference between Client-Server and Peer-to-Peer network is that there is a dedicated server and specific clients in the client-server network model whereas, in peer-to-peer each node can act as both server and client.
- In the client-server model, the server provides services to the client. However, in peer-to-peer, each peer can provide services and can also request for the services.
- In the client-server model, sharing information is more important whereas, in peer-to-peer model connectivity between peers is more important.
- In the client-server model, data is stored on a centralized server whereas, in peer-to-peer each peer has its own data.
- In peer-to-peer model, the servers are distributed in a system, so there are fewer chances of server getting bottlenecked, but in the client-server model, there is a single server serving the clients, so there are more chances of server getting bottlenecked.
- The client-server model is more expensive to implement than peer-to-peer.
- The client-server model is more scalable and stable than peer-to-peer.
It depends on the environment which network model to implement ; each model has its own strength and flaws .
