Mininet_wifi iperf 具有一台服务器和多个客户端

编程问答 2022-05-03

问题描述

我有这个 mininet-wifi 拓扑脚本

def topology(args):

    "Create a network."
    net = Mininet_wifi(controller=RemoteController,roads=10,link=wmediumd,wmediumd_mode=interference)

    info("*** Creating nodes\n")
    for id in range(0,10):
        min_ = randint(1,4)
        max_ = randint(11,30)
        net.addCar('car%s' % (id+1),wlans=2,min_speed=min_,max_speed=max_)

    rsu11 = net.addAccesspoint('RSU11',ssid='RSU11',mode='g',channel='1')
    rsu12 = net.addAccesspoint('RSU12',ssid='RSU12',channel='6')
    rsu13 = net.addAccesspoint('RSU13',ssid='RSU13',channel='1')
    rsu14 = net.addAccesspoint('RSU14',ssid='RSU14',channel='6')
    #c1 = net.addController('c1')
    c1 = net.addController('c1',controller=RemoteController,ip='172.17.0.2',port=6633)
    c2 = net.addController('c2',ip='172.17.0.3',port=6633)
    c3 = net.addController('c3',ip='172.17.0.4',port=6633)
    info("*** Configuring Propagation Model\n")
    net.setPropagationModel(model="logdistance",exp=3)

    info("*** Configuring wifi nodes\n")
    net.configureWifiNodes()

    info("*** Associating and Creating links\n")
    net.addLink(rsu11,rsu12)
    net.addLink(rsu11,rsu13)
    net.addLink(rsu11,rsu14)
    for car in net.cars:
        net.addLink(car,intf='%s-wlan1' % car,cls=mesh,ssid='mesh-ssid',channel=5)

    if '-p' not in args:
        net.plotGraph(max_x=1000,max_y=1000)

    net.startmobility(time=0)

    info("*** Starting network\n")
    net.build()
    c1.start()
    c2.start()
    c3.start()
    rsu11.start([c1])
    rsu12.start([c1])
    rsu13.start([c2])
    rsu14.start([c3])

    for id,car in enumerate(net.cars):
        car.setIP('192.168.0.%s/24' % (id+1),intf='%s-wlan0' % car)
        car.setIP('192.168.1.%s/24' % (id+1),intf='%s-mp1' % car)

我尝试了这种方式来测试一台服务器和另外两个客户端之间的连通性

    car1,car2,car3= net.get('car1','car2','car3')
    car1.cmd('iperf -s -e -u --histogram=100u,2000 --realtime &')
    car2.cmd('iperf -c 192.168.0.1 --isochronous=60:100m,10m -i1 -u -e --realtime > server.txt')
    car3.cmd('iperf -c 192.168.0.1 --isochronous=60:100m,10m -i1 -u -e --realtime >> server.txt') 
    p=Popen('''cat server.txt | grep % | tr," " | awk '{print $10" "$11" "$13" "$16" "$17}' >> test.txt''',shell=True,stdout=PIPE,stderr=PIPE)

它运行良好，但是，现在我想测试 car1 作为服务器和所有其他汽车作为 for 循环中的客户端之间的连接性。有人可以帮我吗？
