La domanda
Il lettore SuperUser KronoS si trova in una posizione interessante: ha accesso alla sua vecchia connessione Internet e alla sua nuova connessione internet per un periodo di tempo. Durante questo periodo vuole testarli:
Right now I’m in the process of possibly switching from a Cable provider to a DSL provider. I have both connections live, and before I cancel one or the other, I’m wanting to do some exhaustive testing of the internet connection. I have three major questions:
- What are some approaches that I can quantitatively test the speeds (both up and down) and quality of my internet connections (ping, time connection is down, etc,.)?
- Are there other consideration that should be taken when testing an internet connection?
- Are there any tools that can do this automatically and capture results?
Overall, I’m looking to compare the two connections over multiple periods of time such as peak hours (1600 – 2100 in my area), and with different loads such as streaming movies, uploading files, etc,.
Qual è il metodo migliore per quantificare quantitativamente i diversi aspetti delle connessioni dati?
La risposta
Collaboratore SuperUser Dennis offre la seguente batteria di test da provare:
The Broadband Tests and Tools from DSLReports.com include a simple speed test, as well as long- and short-term line quality tests:
1. Speed Tests
Test your maximum upload speed and download speed from several geographically distributed locations. Java, Flash and iPhone speed test (100% browser) available.
2. Smokeping
Intensively monitor an IP address for 24 or more hours to review packet loss and/or excessive latency variability - from three different US locations 3. Line Quality – Ping Test
Test latency, jitter and packet loss to your IP address, including identification of any problems en-route to you.
The speed test requires Flash or Java; the other two require that your IP is pingable.
In the absence of a specialized tool for long-term speed tests, you could use a command-line network retriever (e.g. Wget or Wget for Windows) and download uncompressable test files with a shell/batch script.
The nearest test files to Arizona I could find are from speedtest.dal01.softlayer.com (Dallas, TX) and speedtest.sea01.softlayer.com (Seattle, WA).
