Description: The research paper Distributed Packet Switching for LAN Ethernet Seminar Report speaks on Distributed packet Switching for Local Area Network (LAN).The research paper suggests that Ethernet is a contention media access method that allows all the hosts of a network share a link in a secure way. Ethernet has gained popularity because of its relatively easier integration into an existing system. Fast Ethernet and Gigabit Ethernet are comparatively more popular versions. The Carrier Sense Multiple Access with Collision Detect (CSMA/CD) allows sharing of bandwidth evenly without having to share with any other device. Such a thing has been designed to avoid collision when data is shared among various end users or nodes. CSMA/CD allows a secure transmission. Bridges and routers prevent effective transmission being carried out through the entire network.
How does CSMA/CD Protocol Work: Whenever there is a transmission process the host checks whether there is any blockage in the pathway? If there isn’t any the host goes about transmitting. The process doesn’t end here, the protocol keeps tracking if there is any transmission simultaneously from another host. If there is any interruption like that the protocol blocks it to facilitate smooth transmission once again. If there are multiple signals then also the protocol blocks. The hosts have to wait for the transmission, but until then there would be a timeout.
Full-duplex Ethernet can be used in three situations: With a connection from a switch to a host, with a connection from a switch to a switch, with a connection from a host to a host using a crossover cable.
Conclusion: Thus Ethernet plays a very effective role in secure transmission. It doesn’t allow multiple transmission and blocks interrupting transmissions until there’s a time out.
