內容簡介
這個外掛有什麼作用?
這個外掛可以計算網站每月所需的托管頻寬。
它是如何運作的?
它會讀取網頁大小(從使用者提供的網址),並且根據使用者輸入的每月頁面瀏覽次數來計算所需的每月托管頻寬,並將其顯示為側邊欄小工具。
什麼是頻寬?
頻寬在網站托管中指的是網站與互聯網之間允許通信的數據傳輸量。因特網服務提供商(ISP)會基於進出其服務器的連接類型來確定分配的頻寬量。因特網由數百萬台計算機組成的網絡相連,可用的頻寬是根據每個連接的大小計算的。每個人與 ISP 的個人連接只是可能存在的數千種連接之一。這些對 ISP 的綜合連接隨後通過一個更大(有時是多個)的連接傳輸到因特網。整體頻寬必須足夠滿足所有客戶的需求。
以比特為單位計算的頻寬被分組為字節,以構建文本和其他在計算機和互聯網之間傳輸的信息。每個存儲的字符相當於一個字節。一個GB(千兆字節)等於1,024 MB(兆字節),大約相當於一部完整的電影的大小。流量是指在任何時候在網絡連接上傳輸的比特的總數。與公路交通相似,網絡上的數據傳輸速度在很大程度上取決於由所有使用同一連接的用戶所產生的流量量。當有許多用戶同時傳輸數據時,流量可能變得非常緩慢,以允許每個客戶進行傳輸。增加帶寬將擴大互聯網的水平公路,並讓更多的流量更快地移動。
每當有人訪問你的網站時,都會被視為流量。訪問的頁面會被下載;它只是一個可傳輸的文件。該文件的大小取決於結合的文本、圖像、視頻、音頻等。對於不向訪問者提供任何下載的網站,可以輕鬆地按以下步驟計算頻寬:
步驟1-平均每日訪問者數乘以平均每頁訪問次數。
步驟2-乘以上述結果的平均頁面大小。
步驟3-現在乘以31。(這是基於每月提供千兆字節(GB)頻寬的主機計劃。)
步驟4-乘以所謂的 Fudge Factor。
Fudge Factor基於估計或平均數據計算的結果可能不準確的假設。乘以2或3應該保證不會因頻寬使用量而產生任何超負荷費用。
當訪問者可下載時,計算方法略有變化:
步驟1和步驟2與上述相同。
步驟3-平均每日下載的文件數乘以平均文件大小。將此數量添加到步驟2的結果中。
步驟4-現在乘以31。
步驟5-乘以 Fudge Factor。
對於喜歡簡單計算的人,Numion.com有一些實用的帶寬計算工具。它適用於單位轉換,計算構建網站時的最佳頁面大小,並確定任何特定帶寬大小所能承載的訪問者負載。價格很好,完全免費。

原文外掛簡介
What does this plugin do?
This plugin calculates the amount of monthly hosting bandwidth you’ll need for your site.
How does it work?
It takes the web page size (read from the URL given by the user), and with the user input for monthly page views, it then calculates the monthly hosting bandwidth needed. This is will be displayed as a sidebar widget.
What is bandwidth?
When referring to web hosting, bandwidth is the amount of allowable traffic between a particular site and the internet. The ISP determines the amount of allocated bandwidth by considering the type of connections coming into their servers and going out to the internet. The internet consists of networks that are connecting millions of computers. Available bandwidth is calculated according to the size of each connection. Each individual connection to an ISP is only one of potentially thousands. These combined connections to the ISP are then put through a larger (sometimes multiple) connection to the internet. The overall bandwidth has to be great enough to serve the needs of all of the clients.
Bandwidth, measured in bits, are grouped in bytes to construct text and other information that’s relayed between the computer and the internet. Every stored character is equivalent to one byte. One GB (Gigabyte) is the same as 1,024 megabytes; this is about the size of one full-length movie. Traffic refers to the total number of bits being transferred over the network connection at any given time. Comparable to highway traffic, the speed of data transfer on the internet is greatly dependent upon the amount of traffic generated by all users who are sharing the same connection. When there are many users transferring data at the same time, the traffic can become very slow to allow each client to perform transfers. Increasing the bandwidth broadens the internet highway and lets more traffic move faster.
Whenever someone visits your site, it’s considered traffic. The visited page is downloaded; it’s simply a transferable file. The size of the file depends on the combined text, images, videos, audio, etc. The bandwidth for a site that doesn’t offer any downloading to visitors can easily be determined with the following steps:
Step 1 – Multiply the average number of daily visitors by the average number of page views.
Step 2 – Multiply the above result by the average size of the page.
Step 3 – Now multiply by 31. (This is based upon hosting plans offering Gigabytes (GB) of bandwidth per month.
Step 4 – Multiply by what’s known as the Fudge Factor.
The Fudge Factor is based upon the assumption that any estimates or calculations of averages can be inaccurate. Multiplying by 2 or 3 should guarantee that there won’t be any overcharges for bandwidth usage.
The calculation is slightly amended when you intend to allow downloads by your visitors. This requires the following steps:
Step 1 and Step 2 are the same as above.
Step 3 – Multiply the average downloads of daily files by the average file size. Add this to the outcome of Step 2.
Step 4 – Now multiply by 31.
Step 5 – Multiply by the Fudge Factor.
For those who like calculations made simple, Numion.com has some useful bandwidth calculators. It’s good for unit conversion, calculating the optimum page size when building a site and determining the visitor load that can be handled with any particular size of bandwidth. The price is right, too. It’s completely free.
