Graded Discussion Board

Dear Students

Graded Discussion Board (GDB) for this course will be opened on March 01, 2022, for discussion and it will remain open for 2 days (48 hours) till on March 02, 2022.

Topic/Area for Discussion: “Networking and internet: Multimedia Streaming”

GDB Problem Statement

The use of computers, mobile phones, and communication technologies is increasing day by day. People around the globe are using internet services for social interaction, online business, online shopping, flight reservation, and various other activities. The use of communication technologies also helped educational institutes to survive during the current pandemic situation but they faced a lot of difficulties in providing education to the students at their homes. For sharing valuable knowledge among the students of various departments, an educational institute is planning to develop a video streaming service of its own for streaming lectures of different disciplines. They need to use a suitable streaming technology that is secure, and efficient in resource allocation and bandwidth utilization. Following are the two choices for adopting the mode of multimedia streaming:

·        Multicast

·        Broadcast

GDB Question: Keeping the above scenario in view, which mode of streaming will you prefer? Briefly explain with solid reason in concrete form.

Note:

For acquiring the relevant knowledge, don’t rely only on handouts but also watch the course video lessons and read additional material available online or in any other mode.

Important Instructions:

•            Your comments should be concise and to the point.

SOLUTION:

According to our GDB, I will select Multicast streaming. In Multicasting, the packets go to a required set of devices on the network. Multicasting has one/more senders and one/more recipients participating in data transfer traffic. In multicasting traffic recline between the boundaries of unicast and broadcast. Its server’s direct single copies of data streams are then simulated and routed to hosts that request it. IP multicast requires the support of some other protocols such as IGMP (Internet Group Management Protocol), Multicast routing for its working. And also, in Classful IP addressing Class D is reserved for multicast groups.

Broadcasting	Multicasting
It has one sender and multiple receivers	It has one or more senders and multiple receivers.
It sent data from one device to all the other devices in a network.	It sent data from one device to multiple devices.
It works on star and bus topology	It works on star, mesh, tree, and hybrid topology.
It scales well across large networks	It does not scale well across large networks.
Its bandwidth is wasted	It utilizes bandwidth efficiently.
It has one-to-all mapping.	It has one-to-many mapping.
Hub is an example of a broadcast device	The switch is an example of a multicast device.
