What are the characteristics of multicast transmission?
Multicast transmission is a way to transfer the real-time applications’ spreads to the numerous of the subscriber and high-bandwidth.it is efficient and effective than unicast transmission, which transfers data to the individual recipient.in simple terms, the multicast from the source sends one data stream and they are allowed to replicate to stream to the different subscriber.
For example, the cable network on the TV they are providing the signal to various users because they are using the method of multicast transmission the main sender is one but it is distributed to many receivers. The multicast in the networking is to send the same packet to a group of different clients.
The IP multicast is the same as the unicast but the main difference between them is the Class of destination which is the Class D IPv4 address in the multicast. The protocol for the multicast is UDP. Multicast is of use till the clients need the same type of data at the time and during this, the bandwidth provided by the multicast is high.
LANs such as the Ethernet mostly assist multicast transmission, the shared LAN causes the packets to arrive at the NIC which is connected to the LAN. Nowadays the LAN does not have the NIC card instead the multicast implements the adapter to receive the packets and remove the unnecessary ones.
Application of the multicast transmission
The multicast transmission used in the various platforms and some of them are discussed here:
Use on IP network: The multicast is useful in the real-time application i.e., news events and the distribution of the scores in the sports. The application can be auditory and visuals or in the form of text messages. with the help of the IP multicast, it is low in cost and the CNN is the big IP multicast.
Corporations: The corporation uses multicast for employees’ training and keeps them up to date with the news and the events that occur in the company. All the annual year meetings with the shareholder broadcast with the help of it.
Politics: The political parties use multicast to inform them about the development of the projects and call them in case of an emergency.
What are the three characteristics of multicast transmission? (Choose three.)
Answer: the broadcast message has the single frames which are sent to hosts in the network, these are for the IPv4 request and map the upper layer to the lower layer address. The multicast is single frames sent to a bunch of hosts and the protocol for the exchange routers are OSPF and RIPv2.the address 224.0.0.0 to 224.0.0.255 is for the local link address for the bunch of local network access.
