Question

- What is meant by term “inelastic traffic” on a network?

- Explain the primary difference between network applications that use client-server architecture and applications that use peer-to-peer architecture.

- What is meant by the term “peer-churn” with respect to peer-to-peer application architectures?

- Describe in one sentence what is represented by a “port” number to the protocol operating in the transport layer in layered protocol architecture.

Please don't copy and paste from the internet. Thank you

Answer 1

ANSWERS :

ANS 1. Inelastic traffic is a less flexible traffic. It basically means a traffic which does not easily adjust to the changes that are caused in delay and also the throughput. Example : video, audio stream.

ANS 2. Primary difference between client server and peer to peer architecture :

a) In client server a central data storage is available but in peer to peer , each and every peer has its own data storage.

b) Client serve main focus is on information sharing whereas in peer to peer the main focus is on the connectivity between the peers.

c) Client server is much more reliable and stable than the other as the peer to peer stability may vary with the number of peers that are connected.

d) Client server can be used in any size of network but peer to peer is suitable for small networks only.

e) If compared on the basis of cost client server is more costly than the peer to peer.

ANS 3. Peer chrun with respect to peer to peer network means that within the peer to peer network the peers which are connected can join and leave the network whenever they wish to and no restriction on the time as when they can join or leave. Peer churn is a inherent property of peer to peer system. It is a measure to deduce critical design and evaluate thode design and network.

ANS 4. The port number is a method to identify the process to which a message is send when it arrives at the server and is to be transferred to the recipient.
