unspecified bit rate meaning in Chinese

未指定比特率

But all of these algorithms in literatures concentrate in how to improve the qos of high priority traffic sacrificed the delay of ubr ( unspecified bit rate ) traffic
但是这些算法都集中在为高优先级业务提高qos而牺牲ubr ( unspecifiedbitrate )业务的平均时延。
One of the important characteristics of atm networks is that the atm networks support several service types to meet applications with different qos . in uni 4 . 1 , the service types are constant bit rate ( cbr ) , variable bit rate ( vbr ) , available bit rate ( abr ) , and unspecified bit rate ( ubr )
Atm网络的一个重要特征就是它能提供几类服务以满足不同服务质量的要求，这包括：恒定比特率( cbr ) 、未定比特率( ubr ) 、可用比特率( abr )以及可变的比特率( vbr )服务。
