You are hired to design a reliable byte-stream protocol that uses a sliding window (like TCP). This protocol will run over a 1-Gbps network. The RTT of the network is 200 ms.

How many bits would you include in the AdvertisedWindow field of your protocol header? (choose the closest number that can satisfy the above requirement).

Hints:
- First, determine how much data to keep the pipe full (i.e. delay * bandwidth)
- Second, if we assume the window is measured in bytes then calculate how many bits are required in the AdvertisedWindow field to represent those data in pipe.

Answer #1

The maximum amount of data that will fit is given by the Bandwidth Delay Product

Bandwidth Delay Product = Bandwidth x RTT = 1 Gbps x 200 ms = 25,000,000 bytes / sec

No. of bits needed in the window is

    You are designing a reliable byte stream transport layer protocol (not TCP) to operate over a 1x107 bps network and it is using a sliding window for flow control. The time for keeping the transmission pipe full is taken to be the RTT of the network which is 50ms. Each number in the advertised window or sequence number represents 2 bytes of data. a) What is the minimum number of bits necessary for the Advertised Window field of your protocol...

    I need help with this assignment, please; Programming Assignment 3: UDP Pinger Lab In this lab, you will study a simple Internet ping server written in the Java language, and implement a corresponding client. The functionality provided by these programs is similar to the standard ping programs available in modern operating systems, except that they use UDP rather than Internet Control Message Protocol (ICMP) to communicate with each other. (Java does not provide a straightforward means to interact with ICMP.)...
