What are the different problem in lan traffic

[Sandroo]

What are the different types of problem occurs on a lan network data transfer. I had found that while copying the data the entire network works very slow. It takes really long to data transfer. What is needed to improve that. What are the options that effects the working of data transfer. And also post some different network setups.

In the most fundamental category of network created at present is, nodes are easy attached together with the help of hubs. As a network produce, there are a number of potential troubles with this arrangement: Scalability - In a hub network, incomplete shared bandwidth makes it complicated to provide accommodation and important growth without sacrificing presentation. Applications at present necessitate additional bandwidth than still before. Fairly often, the complete network must be redesigned occasionally to accommodate growth.

Latency - This is the quantity of time that it receives a packet to get to its purpose. Since every node in a hub-based network has to remain for a prospect to broadcast in order to avoid crashes, the latency can enlarge considerably as you add additional nodes. Or, if someone is transmitting a huge file across the network, then all of the additional nodes have to stay for a prospect to send their own packets. You have almost certainly seen this before at work, you try to right of entry a server or the Internet and unexpectedly everything slows down to a crawl.

Information on the Network failure - In a characteristic network, one device on a hub can produce troubles for additional devices connected to the hub due to inaccurate speed settings (100 Mbps on a 10-Mbps hub) or extreme broadcasts. Switches can be arranged it to limit broadcast levels. Any part of the network where there is an opportunity that packets from two or additional nodes will interfere with every other is measured to be part of the similar collision domain. A network with a huge amount of nodes on the similar segment will often have a lot of conflicts and therefore a large collision domain.

[Milton.J]

Collisions - Ethernet uses a procedure called CSMA/CD (Carrier Sense Multiple Access with Collision Detection) to correspond across the network. Under CSMA/CD, a node sprit is not transmitting or dispatch out a packet except the network is clear of traffic. If two nodes transmit or dispatch out packets at the similar time, a collision happens and the packets are misplaced. Then equally nodes wait a random amount of time and retransmit the packets.
