(Systems and Networks)
Consider sending a large file from a host to another host using a reliable connection such as TCP. Suppose the reliable connection uses additive-increase, multiplicative-decrease (AIMD) without slow start for congestion control (see page 221-222 in textbook).
Assume a congestion window size of 1 MSS at the start of the transmission and an increase by 1 MSS every time a batch of ACKs is received within an RTT and a multiplicative decrease of 0.5 (half the size of a congestion window) when congestion occurs.
Given these parameters, what is the average throughput (in terms of MSS and RTT) for this connection for 10 RTTs with congestion occurring immediately after the 5th RTT (so before the 6th RTT)?
Report your answers in MSS/RTT. Hint, do not use the formula discussed on page 222 of the textbook (Computer Networks: A top-down approach).
Instead, come up with a systematic approach that calculates step-by-step the number of transmissions in terms of MSS after every RTT. Enter the numeric value of the result.
Describe a parameter passing mechanism that will allow the safety of call-by-value and the efficiency of call-by-reference.
Modern relational database management systems have been around for a relatively short period of time. As time goes by, more and more emphasis has been placed on design issues, especially database modeling. What is the reason for this increased emp..
