ICTO Tips – Campus Network Performance Test And Feedback Platform

2023-12-31T00:08:11+08:00

ICTO推出校園網絡性能測試的目的是甚麼？

為了讓各位能更迅速地診斷並測試校園網絡性能，我們推出新的「校園網絡性能測試及反饋平台」(https://speedtest.icto.um.edu.mo)。此平台專為教職員和學生設計，能夠在遇到網絡問題時提供測試及提交檢查要求。

透過您的參與、測試和反饋，我們將能更有效地識別並跟進校園不同區域（包括課室、宿舍和辦公室等）的網絡性能問題。這將大大幫助我們提升整體的網絡服務品質。

我們非常重視您的意見，並會積極回應和改善。目標是為您提供更優質、更可靠的校園網絡服務。

內聯網速度測試和互聯網速度測試之間主要區別有以下幾點：

  1. 測試範圍
    1. 內聯網測試主要針對校園局域網（LAN）內部網絡進行測試，測量的是用戶端設備與校園伺服器設備之間的連接速度。

    2. 互聯網速度測試則是測試用戶端設備通過校園網絡連接到澳門本地互聯網服務供應商與外部互聯網之間的連接速度。

  2. 測試目的
    1. 內聯網測試是評估校園局域網中有線或無線網內部通訊性能，以確定內部數據共享、教學及行政應用程序運行等方面的效能和速度。
    2. 互聯網速度測試則是評估用戶端設備與互聯網之間的連接速度，以確定您在瀏覽網頁、下載文件、視像會議以及觀看串流媒體等方面的情況。
  3. 測試方法
    1. 內聯網測試可通過使用「校園網絡性能測試及反饋平台」中選擇「內聯網」進行，測量校園局域網內部的傳輸速度、延遲時間等指標。
    2. 互聯網速度測試亦可通過使用「校園網絡性能測試及反饋平台」中選擇「互聯網」進行，通過與遠端外部互聯網測試服務器的連接進行測試，測量您的傳輸速度、延遲時間等指標。

總的來說，內聯網測試關注您的設備與校園局域網中有線或無線網內部通訊之間的連接性能，而互聯網速度測試則關注您的設備與外部互聯網之間的連接性能。兩者都有其獨特的目的和測試方法，可以幫助我們評估和優化網絡連接。

如果您在使用校園網絡服務時遇到問題，請填妥校園網絡性能報告表，提供相關資料以便進一步跟進。詳情可參閱以下指引：

如何向ICTO報告校園網絡性能？

一般網路使用每台裝置所需的Mbps（兆位元組每秒）數量會根據使用情況和需求而有所不同。以下是一些一般情況下的參考值：

 

最少

郵件

1 Mbps

1 Mbps

網絡瀏覽

3 Mbps

5 Mbps

社交媒體

  1. 瀏覽網頁和收發電子郵件：每台裝置通常需要至少1-5 Mbps 的連接速度。這足以順暢地瀏覽網頁、收發電子郵件和執行一般的上網任務。

  2. 高清串流影片：如果您希望在裝置上觀看高清（1080p）的串流影片，每台裝置通常需要至少5-10 Mbps 的連接速度。更高的串流品質（如4K）可能需要25Mbps或更高的速度。

  3. 在線遊戲和視訊通話：玩線上遊戲和進行高品質視訊通話所需的連接速度取決於具體的遊戲或通訊平台。通常而言，每台裝置需要至少3-10 Mbps 的連接速度，以確保一定的遊戲體驗或視訊通話品質。

現時在一般情況下，互聯網速度可以達到50Mbps（6.25MBps）。在非繁忙時段，互聯網速度可高達200Mbps（25MBps）。
值得注意的是，這些數字僅供參考，實際所需的連接速度還會受到其他因素的影響，例如網絡擁塞（在同一時間或空間內多個裝置進行高帶寬活動、下載或上傳大檔案等）、所連接的網站或應用與澳門本地互聯網供應商的連線速度、目的地伺服器負載等外在因素影響。

What is the purpose of the ICTO speed test?

In order to make it faster to diagnose and test campus network performance, we launch the new “Campus Network Performance Test And Feedback Platform” (https://speedtest.icto.um.edu.mo). Designed for staff and students, this platform provides speed testing in case of encounter network issues and submits testing results.

Through your participation, testing and feedback, we will be able to identify and follow up on network performance issues in different areas of campus (including classrooms, dormitories, offices, etc.) more effectively. This will greatly help in improving the overall quality of network services.

We value your feedback and will follow up and improve. Our goal is to provide you with better and more reliable campus network services.

  1. Test Scope:

    1. The Intranet speed test is mainly tested for the Campus Local Area Network (LAN) internal network and measures the connection speed between the client device and the campus data center server equipment.

    2. The Internet speed test tests the connection speed between the client device and the Local Internet Service Provider (ISP) to the external Internet through the campus network.

  2. Purpose of the test:

    1. The Intranet speed test evaluates the performance of wired or wireless network internal communications in Campus LAN to determine the efficiency and speed of internal data sharing, teaching, and administrative application operation, etc.

    2. The Internet speed test evaluates the connection speed between the client device and the Internet to determine how well you are browsing the website, downloading files, video conferencing, and watching streaming, etc.

  3. Test Method

    1. The Intranet speed test can be carried out by selecting “Intranet” in the “Campus Network Performance Test And Feedback Platform” to measure the transmission speed, delay time and other indicators within the Campus LAN.

    2. The Internet speed test can also be carried out by selecting “Internet” in the “Campus Network Performance Test And Feedback Platform”, and the test is conducted through the connection to an external Internet test server to measure your transmission speed, delay time, and other indicators.

Overall, the Intranet speed test focuses on the connection performance between your device and the internal communication of the wired or wireless network in the Campus LAN, while the Internet speed test looks at the connection performance between your device and the external Internet. Both tests have their own unique purpose and testing methods that help us evaluate and optimize network connections.

If you encounter problems using campus network services, please complete The Campus Network Performance Report Form and provide relevant information for further investigation. For details, please refer to the following FAQ:

How to report campus network performance to ICTO?
https://faq.icto.um.edu.mo/how-to-report-campus-network-performance-to-icto/

The transfer speed in Mbps (megabytes per second) required in each device for common network use will vary depending on usage and need. Here are some reference values:

  1. Web browsing and Email: Each device typically requires a transfer speed of at least 1-5 Mbps. This is enough to browse the web smoothly, send and receive e-mail, and perform general online tasks.

  2. Streaming HD video: If you want to watch streaming video in high definition (1080p) on your device, you typically need a transfer speed of at least 5-10 Mbps per device. Higher streaming quality, such as 4K, may require speeds of 25Mbps or higher.

  3. Online gaming and Video conference call: The transfer speed you need to play online games and make high-quality video calls depends on the specific game or communication platform. Typically, each device requires a transfer speed of at least 3-10Mbps to ensure certain gaming experience or video call quality.

At present, under normal circumstances, the Internet speed can reach 50Mbps (6.25MBps). During off-peak hours, Internet speeds can be as high as 200Mbps (25MBps).

Please note that these figures are for reference only, and the actual required transfer speed will also be affected by other factors such as network congestion (multiple devices in the same time or space for high-bandwidth activities, downloading or uploading large files, etc.), the connection speed of the website or application and the Local Internet Provider in Macau, the loading of the destination server and other external factors.
