广播函数(Broadcasting function)规则 广播允许通用函数(universal functions)以非常有意义的方式处理不具有相同形状(shape)的输入。使用广播需要知道以下两个规则: 维度传播 广播的第一个规则是如果所有输入数组不具有相同数量的维度,则将“1”重复地预先添加到较小数组的shape,直到所有数组具有相同数量的维度。 值传播 ...
thus allowing fast communication on low bandwidth networks. as a result, it works well in web streaming, voip, gaming, broadcasting, etc. how does udp work? this protocol divides the messages into datagrams (packets). the devices in the network forward them to the destination server/...
It is used by broadcasting and multicasting applications. Management processes such as SNMP make use of UDP. Route updating protocols like Routing Information Protocol(RIP) make use of User Datagram Protocol. The process that has an error and flows control mechanism makes use of UDP. One Applicati...

Broadcasting via UDP sends a packet out to all hosts on the local network by sending to a magic broadcast address ("<broadcast>"). This broadcast is filtered by routers by default, and there are no “groups” like multicast, only different ports. Broadcast is enabled by passing True to ...
