我目前正在使用python中的twisted,我试图在多个对等体之间进行多播(每个对等体都可以发送和接收消息,发送消息等)。我的主要看起来像这样:
if __name__ == '__main__':
serial_process_num, address = parse_args()
if serial_process_num == '0':
factory = PeerFactory('0', 'log')
reactor.listenTCP(address[1], factory)
reactor.listenTCP(address[1]+1, factory)
print "Process 0 is listening @" + address[0] + " port " + str(address[1])
print "Process 0 is listening @" + address[0] + " port " + str(address[1]+1)
elif serial_process_num == '1':
factory = PeerFactory('1', '')
host, port = address
print "Connecting to process 0 " + host + " port " + str(port)
reactor.connectTCP(host, port, factory)
print "Process 1 is listening @" + address[0] + " port " + str(address[1]+2)
reactor.listenTCP(port+2, factory)
else:
factory = PeerFactory('2', '')
host, port = address
print "Connecting to process 0 " + host + " port " + str(port+1)
reactor.connectTCP(host, port+1, factory)
print "Connecting to process 1 " + host + " port " + str(port+2)
reactor.connectTCP(host, port+2, factory)
reactor.run()
我保持这个简单,因为我想了解我的错误,所以我只使用3个peer.I从cmd开始第一个带有serial_process_num 0(ex py example.py 0),然后是1和2.Am我正确设置了listeners / connecttcp?每当我在这3个人之间发送消息时,我只会在每个同伴中收到一半消息。 (我使用self.transport.write('示例')
是否存在通过TCPconnect进行多播的替代方式?(即时关注krondos教程)如何在多个对等方之间建立多个连接?
答案 0 :(得分:1)
组播是datagram protocol,这意味着您没有像使用TCP一样的字节流;换句话说,它是一种UDP。所以不,你不能在Twisted或其他方面使用TCP。
