Messages: Nodes communicate with each other by passing messages. A message is simply a data structure, comprising typed fields. Standard primitive types (integer, floating point, boolean, etc.) are supported, as are arrays of primitive types. Messages can include arbitrarily nested structures and a...

节点之间通过消息（message）来发送和接收数据。消息是诸如integer、floating point和boolean等类型的变量。
where 𝑆(𝑖)S(i) denotes the message size of topic i, 𝑅𝑝(𝑖)Rp(i) represents the publishing rate of topic i, 𝐸𝑝(𝑖,𝑗)Ep(i,j) is a Boolean indicating whether host j publishes topic i and 𝐸𝑠(𝑖,𝑗′)Es(i,j′) is a Boolean indicating whether host ...
