電気単位・デシベル表現
電気単位・デシベル表現 目的 1) これから仕事で使うことになる電子工学の単位について基礎を理解すること． 2) dB（デシベル）の取扱いに慣れ，仕事に生かせること． 以上の2つを今回の目標とします． ●SI単位を知ろう 測定をすると，必ずその測定値には単位が付きます．測定をしていると，それは絶対値なのか？ということを聞かれることがあります．つまり，測定には，比較測定と，ある国際基準に基づいた絶対測定があるのです． 比較測定をした場合，その測定値に単位はありません．そのかわり，“比”があまりに大きい場合にはdB（デシベル）表現されたりします．このdBについては，後々考えることにします． 私達が，日頃使う単位は，SI単位と呼ばれるものです．これは，1960年に国際度量衡総会（CGPM）がMKSA単位系を拡張して制定したものです．SI単位とは，英語では，The International Sy
Bug 1112 – TCP goes to dead-lock when both segment-retransmit and ACK-loss occurs
I had a similar problem running TCP in ns-3.11. I created an application that synchronized a 4 node topology using the Mesh Mac, so they each sent new data to every other node in the network after having received data from all other nodes. It caused the nodes to all stay on the same round of data. Every one sent round 1, then round 2, and so on. When contention became high, all the nodes simply st

tcptrace - Official Homepage
tcptrace is a tool written by Shawn Ostermann at Ohio University, for analysis of TCP dump files. It can take as input the files produced by several popular packet-capture programs, including tcpdump, snoop, etherpeek, HP Net Metrix, and WinDump. tcptrace can produce several different types of output containing information on each connection seen, such as elapsed time, bytes and segments sent and

PyViz - Nsnam
Introduction NS-3 PyViz is a live simulation visualizer, meaning that it uses no trace files. It can be most useful for debugging purposes, i.e. to figure out if mobility models are what you expect, where packets are being dropped, etc. There's also a builtin interactive python console that can be used to debug the state of the running objects. Although it is mostly written in Python, it works bot
