前言

odl-neutron是与openstack对接的北向模块，通过抓包分析openstack下发至odl-neutron的北向数据，可以大致了解到neutron的北向模型，以及各种请求的基本数据，便于我们进一步学习odl-netvirt代码，同时对于neutron的业务创建逻辑有一个更清楚的理解,特别是网络、子网、虚拟机、路由器这些创建过程，openstack neutron到底做了什么？基于这个疑问，将总结如下。

1 抓包过滤条件

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

  • 过滤非get rest接口
    http&&http.request.method!=GET && ip.src10.0.0.12 && ip.dst10.0.0.12

  • 过滤uri—最优推荐
    http.request.uri matches “/controller/nb/v2/neutron/.*”
    http.request.uri contains “/controller/nb/v2/neutron”

    帮助信息：

    a-点击右侧过滤按键
    b-搜索search找到相关过滤规则名
    c-在Relation找到匹配条件表达式，
    这里通常包含“==”、“！=”、“>=”、“<=”、“contains”、“matches”等表达式条件；
    d-在vlaue栏目中填入具体匹配条件，这里支持正则表达式选项；
    e-点击ok则可以在相应位置生成相关信息；

2 抓包过程总体分析

在这里插入图片描述
包含流程：

a.创建网络--network POST

b.创建子网--subnet POST

c.dhcp端口添加--ports POST\\ports PUT

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

c.创建路由--router POST

d.创建路由接口--ports POST\\port PUT

3 网络创建

8 总结

8.1 device-owner总结

network:dhcp

router_interface

compute:host-2

8.2 细节分析

  • 创建网络子网，并不会产生端口，使能ｄｈｃｐ会增加相关dhcp接口，不管在openstack原生环境，还是odl环境都是如此；
  • 创建虚机会在ｏｖｓ下发相关端口，从北向分析可知，会有两次更新端口更新事件，相关端口device-owner归属在更新事件中确定。
