Google現在推出一個打擊ISP的線上分析程式，可以掃描該ISP是否惡意限制你的頻寬，造成服務品質沒達到標準。
目前我試用看不出什麼結果…可能目前只能用在美國ISP的階段。無聊的人可以去玩玩看。

（路透華盛頓28日電）Google今天公布一項計畫，目標是逐步讓電腦使用者得以判定，Comcast等網路服務提供者（ISP），是否不當阻斷網路連線或降低傳輸速度。

這項計畫是「網路中立」（network neutrality）爭議的最新發展，像Google等網路內容供應者過去常為此槓上部分ISP業者。

ISP業者說他們需要採取負責任的作法，以管理越來越繁忙的網路傳輸，讓所有使用者都能獲益。但網路內容及應用程式廠商則擔心ISP業者的作法，會歧視或獨厚部分網路傳輸行為。中央社（翻譯）

Google evangelist and Net patriarch Vint Cerf this week unveiled three tools that ordinary Net users can use to see whether their ISPs are choking up on their bandwidth. The research and evaluation tools add more fuel to the reinvigorated Net-neutrality debate.

The M-Lab (Measurement Lab) suite, co-developed by Google, the New America Foundation’s Open Technology Institute, the PlanetLab Consortium, and assorted academic researchers, will comprise five user tools; three are ready now.

The Network Diagnostic Tool tests connection speeds and can diagnose any problems that might be limiting yours. Glasnost — if you don’t know what the word means, ask someone who remembers the 80s — checks specifically to see if BitTorrent is blocked or throttled on your line. The Network Path and Application Diagnosis digs in on problems specific to the 『last mile』 of broadband networks.

The two components not yet available look equally useful. NANO looks at the ISP to see if it’s blocking or throttling specific users, applications, or destinations. And DiffProbe checks traffic prioritization. Cerf’s post says that over the next few months they’ll be providing 36 servers in 12 locations here and abroad to facilitate testing by both end users and researchers.

Even if you’re on the other side from Google in the Net neutrality debate, Cerf writes, the data acquired should be valuable to you. 『No matter your views on net neutrality and ISP network management practices, everyone can agree that Internet users deserve to be well-informed about what they’re getting when they sign up for broadband, and good data is the bedrock of sound policy. Transparency has always been crucial to the success of the Internet, and, by advancing network research in this area, M-Lab aims to help sustain a healthy, innovative Internet.』
