Suppose that the packet length is L= 1000 bytes, and that the link transmission rate along the link to router on the right is R = 1000 Mbps.

1. What is the transmission delay (the time needed to transmit all of a packet's bits into the link) (in milliseconds)?

I know that the answer to 1. is ---> The link transmission delay = L/R = 8000 bits / 1000 Mbps = 0.008 msec.

2. what is the maximum number of packets per second that can be transmitted by the link?

I need to know how to calculate 2. above, please help.

2)Maximum no of packets = R/L

                                        =1000*10^6 bits/1000 bytes

                                        =10^9 bits /8000 bits                    [since 1 byte =8 bits)

                                       =125000 packets /second.

Suppose we have a network in which 3 nodes share a common transmission media. The length of the frame sent by every node is fixed to 1. We also suppose that every node has the probability of 0.6 to generate a frame to be sent in any time period of length 1. Please answer the following questions. a) When pure ALOHA is adopted, what is the probability that a node successfully transmits a frame? b) When slotted ALOHA is adopted,...
