Dobby的网络仿真学习笔记(ns2+qualnet): 802.11b in NS2
http://dobbymmlab.blogspot.com/2008/07/80211b-in-ns2.html
Making NS-2 simulate an 802.11b link. Jpr -at- rice.edu. For a research project I worked on in 2004 (resulting paper here. I used two Netgear MA311 cards to create a simple ad hoc connection. These cards are 802.11b PCI cards, stuck in the back of brand new dell workstations. I did some simple throughput tests using netperf. And found that my results differed significantly from what NS told me. If you want to see my actual results. Of your simulation script:. Mac/802 11 set dataRate 11Mb. Almost all comm...

Rate-Limiting VM Traffic Using QoS Policing
http://www.vswitch.org/support/config-cookbooks/qos-rate-limiting
OpenFlow 1.x Plans. Rate-Limiting VM Traffic Using QoS Policing. The goal of this configuration cookbook is to rate-limit the traffic sent by a VM to either 1 Mbps or 10 Mbps. This configuration cookbook uses an environment configured as described in the following sections. There may be other networks (for example, a network for management traffic), but this configuration cookbook is only concerned with the Data Network. Both VMs (VM1 andVM2) run on Host1. Each VM has a single interface that appears as a...

Storage Adventures: Cluster Interconnect Network Benchmarking
http://sanarchitect.blogspot.com/2010/03/cluster-interconnect-network.html
The greatest adventure is what lies ahead. Monday, March 15, 2010. Cluster Interconnect Network Benchmarking. Is a great tool for benchmarking and stress testing your cluster interconnect. Oracle RAC demands a high bandwidth, low latency interconnect in order to effectively utilize Cache Fusion. Here’s how to benchmark your cluster interconnect network:. Download the source tarball from ftp:/ ftp.netperf.org/netperf/netperf-2.4.5.tar.gz. Add /etc/xinetd.d/netperf with the following contents:. UDP UNIDIRE...

Aaron's: Lessons in network latency
http://ab-rtfm.blogspot.com/2007/11/lessons-in-network-latency.html
Ramblings on information technology. Programming, Security, IT Architecture, and Integration by Aaron Bush. Any fool can know. The point is to understand.". Tuesday, November 27, 2007. Lessons in network latency. At work were recently brought a new site online and connected it to HQ via our MPLS WAN. Almost immediately we began to notice odd behavior out of this site related to the WAN connection. At times we were seeing ping times from our HQ to the sites router go over 1 sec! I had been using Cacti alr...

Deployable Queueing: An Experimental Comparison of Queue Management Schemes in Linux. This web site contains the data files and test scripts for the paper "Deployable Queueing: An Experimental Comparison of Queue Management Schemes in Linux". Physical test setup. All five computers run Debian Wheezy. The latency inducer runs the stock kernel (version 3.2) with the. Module added, while the others have had the kernel replaced with a vanilla kernel version 3.14.4 from kernel.org. Is required for most tests&...

CLI – The RoarinPenguin Techiezone
http://techiezone.rottigni.net/tag/cli
Notes, hints, tips… in one word: experience! CLI stuff in Linux to monitor networking. It was a while I did not post anything on this blog, so I will engage into something cool now 🙂. And into something I will need one day or another: a collection of very, very useful networking commands available for Linux. Let’s start with an easy one: iperf. And its variant with more options, netperf. Very useful to measure TCP/UDP performances between two hosts by pumping traffic either mono or bidirectionally.

RoarinPenguin – The RoarinPenguin Techiezone
http://techiezone.rottigni.net/author/admin
Notes, hints, tips… in one word: experience! It's all about perception. Python 2.7.11 on El Capitan with TLS 1.2 support. It’s been a while since my last post, so I’ve decided to make a magnificent one 🙂. Jokes apart, this setup took me a full sunday hence I thought to recap for future references. The whole story started with a Python script on my Mac OS X unable to retrieve a JSON response from a specific https site, whereas the exact same script run like a champ in Kali Linux. And brew install openssl.
