Therefore, when it is configured for bridging mode and installed at the subscriber's location with the necessary splitters/microfilters, it trains up automatically upon power up. When the CPE trains up, it indicates that the physical layer between the CPE and DSLAM is fine. Depending on how the end station?s IP address is configured (that is, whether it is assigned via a DHCP server or it is a static IP address with default gateway information), it can then communicate with the service destination.<br />
<br />
Following is a description of the flow of packets.<br />
<br />
The user's data is encapsulated in IEEE 802.3 from the PC and enters the Cisco 6xx CPE. It is then encapsulated into an Logical Link Control/Subnetwork Access Protocol (LLC/SNAP) header, which in turn is encapsulated in ATM adaptation layer 5 (AAL5) and handed over to the ATM layer.<br />
<br />
<img src="http://farm3.staticflickr.com/2844/8811490930_f36eabd6a0.jpg" width="500" height="333" alt="routed_bridged_encap_1"><br />
<br />
<br />
The ATM cells are then modulated by the ADSL transmission technology, Carrierless Amplitude and Phase (CAP) modulation or Discrete Multi-Tone (DMT), and sent over the wire to the DSLAM. At the DSLAM, these modulated signals are first received by the POTS splitter, which checks whether the frequency of the signal is below or above 4 kHz. After it identifies the signals as above 4 kHz, it passes them to the ADSL Transmission Unit - Central Office (ATU-C) in the DSLAM.<br />
<br />
The ATU-C demodulates the signal and retrieves the ATM cells, which are then passed to the network interface card (NIC) in the multiplexing device (MUX). The NIC looks at the subscriber side VPI/VCI information in the ATM header and makes the switching decision to another VPI/VCI which will be forwarded to the service destination router. After the service destination router receives these cells on a particular ATM interface, it re-assembles them, looks at the upper layer, and passes the information to the BVI interface. The BVI interface looks at the Layer 3 information and decides where the packet is to be delivered.GaRyhttp://www.blogger.com/profile/06319141385208415054noreply@blogger.com0tag:blogger.com,1999:blog-9188044791529307007.post-3297301030473933122013-05-23T01:45:00.000+08:002013-05-23T01:52:00.635+08:0031從家裡到公司大約7.5公里。<br />
<br />
假設從出發到終點是一條直線,且沒有任何停留:<br />
以騎機車、開車來算,時速50耗時9分鐘,<br />
以騎單車來算,時速30耗時15分鐘,<br />
若以跑步來算,配速5.5分鐘/公里耗時41分鐘。<br />
<br />
可是事實上,我到公司必須經過的紅綠燈,總共有31個!<br />
如果一個紅綠燈要停留30秒,那總共得停留15.5分鐘!<br />
<br />
根據之前看到的調查,台灣人平均每天來回通勤24公里。<br />
換句話說,就是每天花費將近兩個小時在通勤上。<br />
塞車、發呆,嚴然成為台灣人的第二專長...<br />
<br />
20年內台灣的交通狀況不會改善到哪裡去,<br />
既然兩個小時的通勤免不了,那我能做的就是想辦法提升這兩個小時的附加價值。<br />

山不轉,幹,我轉。<br />

包括相繼完成了CCNA、CCNP認證,還有做到爆肝的公司前台系統換裝,以及親人過世等等...。<br>
<br>
所以去年底我他媽開始跑步了!(是不是轉太硬了...)<br>
<br>
好吧,主要是因為我的『人生必做25件事』之一,是完成一場『超級鐵人』。<br>
所以我不僅開始練跑,還立馬敗進了一台計時車呢~~<br>

關於VTP,有些被我想複雜了,有些卻被我想簡單了。
<br />
<br />
參考文件:<a href="http://www.cisco.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080094c52.shtml" target="_blank">Understanding VLAN Trunk Protocol (VTP)</a><br />
<br />
1.<br />
這個被我想複雜了<br />
<br />
VTP = Layer2 protocol, why IP here ?<br />
<br />
<a href="http://www.flickr.com/photos/grbiking/7169435061/" target="_blank" title="Flickr 上 獨。釣寒江雪 的 vtp status"><img alt="vtp status" src="http://farm8.staticflickr.com/7097/7169435061_073fca7e04.jpg" /></a><br />
<br />
以為這之中有甚麼驚人的秘密,的確!根本就沒有秘密...<br />
<br />
這個IP是"Updater Identity",識別而已,並不參與VTP的運作。<br />
<a href="http://www.flickr.com/photos/grbiking/7169083485/" target="_blank" title="Flickr 上 獨。釣寒江雪 的 summary advertisement packet format"><img alt="summary advertisement packet format" height="317" src="http://farm9.staticflickr.com/8168/7169083485_c74523e8a4.jpg" width="500" /></a><br />
Code = 0x02 = <span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">advertisement </span><br />
<br />
2.<br />
這被我想簡單了<br />
我以為VTP server就一直把advertisement packets丟出去,client就一直撿起來compare這樣。<br />
但事實上client是會發出advertisement request的。<br />
<br />
advertisement request packet format :<br />
<a href="http://www.flickr.com/photos/grbiking/7354295886/" target="_blank" title="Flickr 上 獨。釣寒江雪 的 Advertisement Requests"><img alt="Advertisement Requests" height="182" src="http://farm9.staticflickr.com/8157/7354295886_95168fe297.jpg" width="500" /></a>
<br />
Code = 0x03 = advertisement request<br />
<br />
而且還會針對沒被update的部分發出request,有聰明。<br />
<br />
3.<br />
這點我到現在還不明白:為什麼明明是layer2的 "frame",cisco要把它叫做 "packet"?<br />
知道的大德請不吝賜教~~~~<br />

<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">10^8其實就是100Mbps,當時會用100M做分子不是巧合,而是在1991年時100M仍然是個神話。後來因為資源共享的氣候形成,導致對網路頻寬的需求暴增,802.3u(FastEthernet)很快地在1995年通過RFC。其後短短三年時間,OC-3(155M)、802.3z(GigabitEthernet)各種高速網路相繼問世。</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">問題就來了,當大於100M的鏈路套進『10^8/bandwidth』來計算的結果就是無條件進位成1,這將使得cost值形同虛設。所以CISCO早在1994年發布IOS 11.2的時候為metric的計算增加了一個"auto-cost reference-bandwidth"的指令,藉以彌補『10^8/bandwidth』公式的不足。這個指令可以將分子(也就是原本是10^8)的value指定在1到4294967之間,請注意,單位是"<span style="color: red;">megabits per second </span>",而default為100。這樣,OSPF就又可以用上好一陣子了。</span><br />

<br>
通常跑10/100Mb只用到1&2、3&6這兩對線,所以很多不肖廠商就從4&5、7&8去偷料。山寨線大多有這樣的特徵,這條當然也不例外。

<br>
所以iPad到手沒幾天(感謝老妹),我就在Apple Store買了Good Reader。<br>

<img src="http://farm7.staticflickr.com/6216/6364231967_7a82495010.jpg"><br />
官方連結:<a href="" target="_blank">Park Tool Derailleur Hanger Alignment Gauge</a><br />
<br />
後變速器是一個平行四邊形的結構,原則上不管在哪個檔位,導輪都應該平行於飛輪。(紅線B)<br />
<img src="http://farm7.staticflickr.com/6211/6364274147_85a70d1d31.jpg"><br />
後變速器是固定在吊耳(勾爪)上的,所以當變速器遭受外力撞擊的時候,吊耳很容易走針,然後就是變速調到死就是不準,或是有異音。<br />
<br />
在8、9速的時代因為每片飛輪的間距大,遇到吊耳變形用六角扳手插進去喬一喬,目視檢測多半能搞定。不過現在飛輪一多,越來越精密,靠校正規會比較實際。尤其現在的吊耳多半是鋁合金,不小心喬過頭就斷給你看。<br />
