《ODL-Openstack學習系列-01》－odl-neutron北向抓包分析

阿新 • • 發佈：2018-12-12

前言

odl-neutron是與openstack對接的北向模組，通過抓包分析openstack下發至odl-neutron的北向資料，可以大致瞭解到neutron的北向模型，以及各種請求的基本資料，便於我們進一步學習odl-netvirt程式碼，同時對於neutron的業務建立邏輯有一個更清楚的理解,特別是網路、子網、虛擬機器、路由器這些建立過程，openstack neutron到底做了什麼？基於這個疑問，將總結如下。

1 抓包過濾條件

  • 過濾ip和http http.request.method&& ip.src10.0.0.12 && ip.dst10.0.0.12

  • 過濾非get rest介面 http&&http.request.method!=GET && ip.src10.0.0.12 && ip.dst10.0.0.12

  • 過濾uri—最優推薦 http.request.uri matches “/controller/nb/v2/neutron/.*” http.request.uri contains “/controller/nb/v2/neutron”

    幫助資訊：

    a-點選右側過濾按鍵 b-搜尋search找到相關過濾規則名 c-在Relation找到匹配條件表示式， 這裡通常包含“==”、“！=”、“>=”、“<=”、“contains”、“matches”等表示式條件； d-在vlaue欄目中填入具體匹配條件，這裡支援正則表示式選項； e-點選ok則可以在相應位置生成相關資訊；

2 抓包過程總體分析

在這裡插入圖片描述 包含流程：

a.建立網路--network POST

b.建立子網--subnet POST

c.dhcp埠新增--ports POST\\ports PUT

d.vm建立--ports POST\\port PUT\\port PUT

c.建立路由--router POST

d.建立路由介面--ports POST\\port PUT

3 網路建立

8 總結

8.1 device-owner總結

network:dhcp

router_interface

compute:host-2

8.2 細節分析

  • 建立網路子網，並不會產生埠，使能ｄｈｃｐ會增加相關dhcp介面，不管在openstack原生環境，還是odl環境都是如此；
  • 建立虛機會在ｏｖｓ下發相關埠，從北向分析可知，會有兩次更新埠更新事件，相關埠device-owner歸屬在更新事件中確定。
