問題

測試人員為了方便, 常常都固定用單一 DHCP client 實體連接到不同 port 或不同 relay agent, 用來測試不同的 option82 policy rule, 由於單一 DHCP client 其 MAC address 是固定的, 常會觸發 DHCP 實作內的 cache 機制, 導致誤判測試結果, 使用這個方式測試請先了解DHCP 實作原理.

因為 IP 有限, client 卻可能眾多, 大多數 DHCP client , DHCP server 的實作策略都傾向 "不浪費租約, 不輕易給新 IP", client 只要曾經成功在某個條 rule 要到 IP 過, server & client 兩者都會盡最大努力去續記 (cache 住)這份合約.
大部份 DHCP server 實作, 即使因為更改設定而必須重啟, 先前發出去的租約不會清掉, 通通存在內部 database, 重啟時會再 load 出來用.
Windows 7 DHCP client 的實作是, 只要曾經要到過IP, 後面不管是經歷

- A JS interpreter in GO is good begining.
- There are still quite a lot things need to fill from JS to NodeJS
https://github.com/ddliu/motto
- NodeJS's require has been asked in robertkrimen/otto#41
Buffer and other stuff in NodeJS probably will be done in https://github.com/ddliu/nodego

create a smith based net/rpc codec. simulate the following two apis
- codec.MsgpackSpecRpc.ClientCodec -- done
- codec.MsgpackSpecRpc.ServerCodec
pubsub in go-smith
- net/rpc doesn't cover this. It's required to create a server to receive calls.
encoding/transportation conversion
- encoding:
  - json/msgpack gateway.
- transportation

smith/sockjs gateway.

import "github.com/vmihailenco/msgpack" 有很多限制

struct 真的是copy value , 要用 pointer 才能指到同一個 struct variable

package main

import "fmt"

type myst struct {
	age int
}

	/* original link http://blog.gasolin.idv.tw/2014/11/flux-javascript.html */
	// Renderer.js
	var ClickRenderer = {
	init: function s_init(element, Store) {
	this.element = element;
	this.store = Store;
	window.addEventListener('render_view1', this);
	},

	handleEvent: s_handleEvent(evt) {
