We transmit data directly between two servers 6,000 km apart through a geostationary satellite situated 10,000 km from earth exactly between the two servers. The data enters this network at 100mb/s.
a. Find the propagation delay if data travels at the speed of light (2.3 108 m/s).
b. Find the number of bits in transit during the propagation delay. 3. Stored on a flash memory device is a 200 megabyte (mb) message to be transmitted by an e-mail from one server to another, passing three nodes of a connectionless network. This network forces packets to be of size 10kb, excluding a packet header of 40 bytes. Nodes are 400 miles apart, and servers are 50 miles away from their corresponding nodes. All transmission links are of type 100mb/s. The processing time at each node is 0.2 seconds.
a. Find the propagation delays per packet between a server and a node and between nodes.
b. Find the total time required to send this message.
