In a network after a while an 8-flake construction and protocol hierarchy, contacts produce messages of protraction M bytes. Assuming each flake has a opposed header size: 20-byte, 20-byte, 20-byte, 100-byte, 30-byte, 20-byte, 40-byte and 150-bytes for Layers 1, 2, 3, 4, 5, 6, 7 and 8 respectively: What division of the network bandwidth is industrious after a while headers? Please pomp your calculations and briefly expound.
The exploit of a network contact is influenced by two main network characteristics: the bandwidth of the network (sum of bits per pradventure that the network can bliss) and the latency (the relapse skilled by a bit nomadic aggravate the network). Identify the fitnesss of the forthcoming contacts in stipulations of bandwidth and latency, and then afford an development of a peculiar network technology that is correspondent to use for each of these contacts:
File transfers between Melbourne and Germany
Video streaming to a liberal heterogeneous area after a while manifold users neighboring Broome, WA
Connecting a liberal sum of real-time low facts transmission fitness sensors for nice adventure declaration such as a set of sensors in a family or car
Transferring a liberal smooth from topical computer to a topical server
