[rabbitmq-discuss] Fwd: about the Frame of amqp

[femto Zheng]

Hi, so I understand, the Frame is kind of like,
in object oriented terminology, a Message class,
I send a Message to server, and the server gets it,
in Message boundaries,

class Message
  #some properties
end
we can think some marshaling/dump here to mimic amqp's behavior,
it's just like sending Message.
but now I'm puzzled, why do we need segment?Why do we need assembly?
a segment comprises of many frames, an assembly comprises of many segments.
