Taking The Right View -- The Leader's Way, Chapter 1


"Right view relates to the intention behind the decision. Right conduct refers to the quality of actions."

Right View

Right view is based on three following facts:

  1. Having right intention
  2. Understanding cause-effect law
  3. Having right state of mind
Having right intention is to think about self and others: not self, not other, but both self and others.

How to Read My Book

At the beginning, there was frustration.

First of all, I would like to thanks everyone for purchasing the NS2 book. The book was motivated by my frustration when I learned NS2 a long time ago. I guess everyone would at one time share that frustration with me. NS2 is a great tool. It has numerous modules.
Unfortunately, it does not have enough good documentation. With that, I began writing the book in order to help you guys get started with NS2. I appreciate everyone coming to this website, and every comment that you have on the book. Again, thank you.

Classifiers and Routing Modules: Putting a routing modules rtnotif_ and ptnotif_ in a node using "$ns node"

Note: This is a detailed note for the book, Introduction to Network Simulator NS2. You may have to read chapter 6 of the book for better understanding.

Introduction

This post is a sequel of the previous post, which demonstrated the relationship of classifiers, routing modules, and nodes:
What’s in This Post

So far, what we have looks like the figure below. In the previous post, I discussed how the blue block (classifier_) is inserted in to a node.



This post focuses on how two yellow blocks are placed into a node.

[BookReview] THE Leader's Way: Business, Buddhism and happiness in an interconnected world by His Holyiness The Dalai Lama and Laurens Van Den Muyzenberg

At first glace, business and religion seem to live in different world. But, in fact, both share the common purpose. They both seek happiness.  

The main idea of this book is to apply right view and right conduct to the free market world. The book consists of three parts. Part one focuses on a personal level. It presents the meaning of right view and right conduct that a leader should have, and instructs how one can train his/her mind in busy daily life. Part two moves on to what role leaders should play in an organization. Finally, Part three discusses the right role of the organization in our society.

Text-to-speech and Audiobook

Texts are in a book. Speech is a form of audio. When we convert text to speech, we should get an audiobook, right? Not quite!! In fact, text-to-speed and audiobook are quite different.

Classifiers and Routing Modules: Putting a default classifier in a node using "$ns node"

Note: This is a detailed note for the book, Introduction to Network Simulator NS2. You may have to read chapter 6 of the book for better understanding.

Introduction

This post is a sequel of the previous post, which demonstrated the relationship of classifiers, routing modules, and nodes: What are they, their purposes, their relationship, and how to configure them conceptually.

What's in This Post

Now that you get the concept, let's look at how NS2 actually configure them. I will demonstrate the process by walking through a command $ns node, which creates a node.
This post focuses mainly on how a default classifier, namely classifier_, is create and inserted into a node. I will discuss about routing modules in subsequent posts.
