    以上面的配置为例，假设消费者在CENTER标的na62机房，请求上下文中的user_unit属于CENTER

    那么我们有以下路由流程：

    我们经过 UnitRouter 时，地址被划分为四个部份

    • CENTER：
    1. 10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    2. 10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    3. 10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    4. 10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    • UNSH
    1. 10.0.0.4:12200?_p=hessian2&APP=demo&st=et12&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSH
    2. 10.0.0.5:12200?_p=hessian2&APP=demo&st=et12&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSH
    • UNSZ
    1. 10.0.0.6:12200?_p=hessian2&APP=demo&st=SA128&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSZ
    2. 10.0.0.7:12200?_p=hessian2&APP=demo&st=SA128&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNSZ
    • UNZBMIX

    因为 user_unit属于CENTER，所以我们选择CENTER的部分，作为MachineRoomRouter的地址输入，即为

    CENTER

    1. 10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    2. 10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    3. 10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    4. 10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

    na61

    1. 10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

    na610

    1. 10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

    na62

    1. 10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    2. 10.0.0.8:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
    3. 10.0.0.9:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
    4. 10.0.0.10:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX

    na620

    1. 10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    fallback

    由于消费者在 na62 机房发起调用，匹配了

    1.        - name: na62-samesite-route  // 把 na62 机房的流量打到 na62 机房
    2.          match:
    3.           - sourcelables:
    4.              sigma.ali/site: na62
    5.          route:              
    6.           - destination:
    7.              host: demo
    8.              subset: na62

    na62

    1. 10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    2. 10.0.0.8:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
    3. 10.0.0.9:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX
    4. 10.0.0.10:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=UNZBMIX

    而UnitRouter给MachineRoomRouter的输入为

    CENTER

    1. 10.0.0.1:12200?_p=hessian2&APP=demo&st=na61&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    2. 10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    3. 10.0.0.3:12200?_p=hessian2&APP=demo&st=na610&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
    4. 10.0.0.4:12200?_p=hessian2&APP=demo&st=na620&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER

    两个取交集的结果为

    这个结果将做为一下路由的输出,重复前面的动作；

    1. 10.0.0.2:12200?_p=hessian2&APP=demo&st=na62&v=2.0&_TIMEOUT=3000&_ih2=y&mg=demohost&_CONNECTTIMEOUT=1000&_SERIALIZETYPE=hessian&ut=CENTER
