however, udt is indeed optimized for bulk data, and it may not have any better performance for message signaling applications 可是,udt的确为巨大的数据做过优化,并且它对基于消息信号的应用不会有任何性能上的提升。
in electrical communications the information source provides an electrical signal, usually derived from a message signal which is not electrical ( e . g . sound ), to a transmitter comprising electrical and electronic components which converts the signal into a suitable form for propagation over the transmission medium 在电通信中,信息源提供一个电信号到传输器上,这个电信号通常来源于一个非电的消息信号例如声音.传输器由电器件和电子器件构成.它把信号转化为一个合适的形式,从而在传输媒介上传播
