This section post will discuss mostly ethernet and how it relates to 2.1.a implement troubleshoot switch administration. All of the information here is a good intro to subsections of this section and those concepts build off of this. I am going to use this parent section to discuss ethernet, and some of its properties. I …

Describe TCP global synchronization and the problems it causes and possible fixes for it. As shown above TCP global synchronization is when multiple TCP flows experience congestion at the same time, thus they all drop to their slow start threshold at the same time, and start linearly increasing again. The immediate drop at the same …
The bandwidth delay product is how TCP calculates its receive window size. The formula is simple. BDP (in Bits) = bandwidth (bits) * RTT (sec) Now we need to convert the BDP from bits to Bytes to tell us our best TCP receive window size to use. This size in Bytes is how much bandwidth …
To better understand TCP window Size Scaling we first need to understand the TCP Windows, thus I am copying the section I wrote from 1.1.e Explain TCP Operations here… Window size (in Bytes)- 1.Receive window size: Each host in a TCP connection sets their receive window size meaning this is the most the host will …
