Tor Relays 觀測點

ASN 自治網路觀測資料分析 接續討論「連線層的在地觀測」。前兩篇看的是「我們在測什麼網站」與「測量端落在哪些 ASN」,這篇換到節點端:台灣有多少 Tor 中繼節點、跑在哪些 ASN 上、貢獻多少頻寬。中繼節點的數量與分散程度,是台灣對全球 Tor 網路貢獻量的直接指標。頁面也順帶列出日本、南韓、香港的同期資料,作為鄰近地區的參照。

觀測地區:

此頁面持續追蹤各地區 Tor 中繼節點的運作狀況,資料每小時從 Tor 網路收集一次、以天為單位彙整呈現,涵蓋健康度、多樣性與版本分佈等面向。

健康狀態

中繼節點是否正常提供服務,以及整體貢獻的頻寬容量。

  • 持續與停止運作的數量1 { "description": "Tor Relays Running (count), Taiwan", "data": {"url" : "https://anoni.net/api/vega/tor/relays/running?country=tw"}, "mark": { "type": "bar", "tooltip": true }, "encoding": { "x": { "field": "created_at", "type": "temporal", "timeUnit": "yearmonthdate", "axis": {"format": "%m/%d"}, "title": "日期" }, "y": {"field": "count", "type": "quantitative", "title": "數量"}, "color": { "field": "running", "title": "運作狀態", "scale": { "domain": [false, true], "range": ["#ff6384", "#36a2eb"] }, "legend": { "labelExpr": "datum.label == 'true' ? '運作中' : '已停止'" } } } }

  • 每日提供的總頻寬2 { "description": "Tor Relays Running (observed_bandwidth), Taiwan", "data": {"url" : "https://anoni.net/api/vega/tor/relays/running?country=tw"}, "transform": [ {"filter": "datum.running == true"}, {"calculate": "datum.observed_bandwidth/1000000", "as": "observed_bandwidth"} ], "mark": { "type": "area", "tooltip": true, "interpolate": "monotone", "point": true, "line": true }, "encoding": { "x": { "field": "created_at", "type": "temporal", "timeUnit": "yearmonthdate", "axis": {"format": "%m/%d"}, "title": "日期" }, "y": {"field": "observed_bandwidth", "type": "quantitative", "title": "頻寬(MB/s)"} } }

多樣性指標

自治網路(ASN)的分散程度,以及不同節點角色的分佈狀況,反映網路的去中心化健康度。

  • ASN 每日唯一數量4 { "description": "Tor Relays ASN unique count, Taiwan", "data": {"url" : "https://anoni.net/api/vega/tor/relays/asn?country=tw"}, "transform": [ { "aggregate": [{"op": "count", "as": "asn_unique_count"}], "groupby": ["created_at"] } ], "mark": { "type": "line", "tooltip": true, "point": true, "interpolate": "monotone" }, "encoding": { "x": { "field": "created_at", "type": "temporal", "timeUnit": "yearmonthdate", "axis": {"format": "%m/%d"}, "title": "日期" }, "y": {"field": "asn_unique_count", "type": "quantitative", "title": "唯一 ASN 數量"} } }

  • 中繼點類型數量5 { "description": "Tor Relays Node Type (count), Taiwan", "data": {"url" : "https://anoni.net/api/vega/tor/relays/node_type?country=tw"}, "mark": { "type": "bar", "tooltip": true }, "encoding": { "x": { "field": "created_at", "type": "temporal", "timeUnit": "yearmonthdate", "axis": {"format": "%m/%d"}, "title": "日期" }, "y": {"field": "count", "type": "quantitative", "title": "數量"}, "color": { "field": "node", "title": "節點類型" } } }

版本與標籤

Tor 軟體版本的更新狀況,以及各節點所具備的能力標籤分佈。

  • 版本數量3 { "description": "Tor Relays Version (count), Taiwan", "data": {"url" : "https://anoni.net/api/vega/tor/relays/version?country=tw"}, "mark": { "type": "line", "tooltip": true, "point": true, "interpolate": "monotone" }, "encoding": { "x": { "field": "created_at", "type": "temporal", "timeUnit": "yearmonthdate", "axis": {"format": "%m/%d"}, "title": "日期" }, "y": {"field": "count", "type": "quantitative", "title": "數量"}, "color": { "field": "version", "title": "版本" } } }

  • 標籤類型數量6 { "description": "Tor Relays Flags (count), Taiwan", "data": {"url" : "https://anoni.net/api/vega/tor/relays/flags?country=tw"}, "mark": { "type": "line", "tooltip": true, "point": false, "interpolate": "monotone" }, "encoding": { "x": { "field": "created_at", "type": "temporal", "timeUnit": "yearmonthdate", "axis": {"format": "%m/%d"}, "title": "日期" }, "y": {"field": "count", "type": "quantitative", "title": "數量"}, "color": { "field": "flag", "title": "標籤" } } }

下一步


  1. 持續與停止運作的數量:計算每日該地區的 Tor Relay 運作狀態數量,計算區間每小時不重複的 Tor Relay。 

  2. 每日提供的總頻寬:計算每日該地區運作中的 Tor Relay 總頻寬(MB/s),計算區間每小時不重複的 Tor Relay。 

  3. 版本數量:計算每日該地區 Tor Relay 所使用的 Tor 版本號數量,計算區間每小時不重複的 Tor Relay。 

  4. ASN 每日唯一數量:計算每日該地區的 Tor Relay 自治網路編號(ASN)的唯一數量,數值越高代表節點分散於更多不同的網路供應商,去中心化程度越佳。 

  5. 中繼點類型數量:計算每日該地區的 Tor Relay 類型數量,計算區間每小時不重複的 Tor Relay。 

  6. 標籤類型數量:計算每日該地區的 Tor Relay 標籤類型數量。各標籤不互斥,同一節點可同時具備多個標籤。
