Multimedia communication includes many theoretical problems. The 4th part studies media synchronization and Usage Parameter Control(UPC). 多媒体通信包括多方面的理论问题,第四部分研究媒体同步和ATM终端的用户参数控制。
In this paper, we present a fuzzy leaky bucket ( FLB ) model and study its effect with normal leaky bucket ( LB ) in Usage Parameter Control(UPC) ( UPC ). 本文提出了模糊漏桶模型,研究了它与普通漏桶在用户量参数控制(UPC)中的作用。
If to admit this call, the network is notified to allocate network resource to the new connection and submit the new connection's flow parameters to Usage Parameter Control(UPC) module for flow monitoring and billing. 如果接受,就通知网络为新连接分配网络资源,同时把新连接的流量参数送交用法参数控制(UPC)模块进行流量监控和计费。
ATM networks use the preventive congestion control mechanisms such as Usage Parameter Control(UPC) ( UPC ) and Connection Admission Control ( CAC ) to avoid congested conditions. ATM网络一般采用预防性的阻塞控制机制,如用法参数控制(UPC),连接允许控制(CAC)来避免阻塞状况的发生。
The usage result testifies that the injection device is reasonable in scheme and accurate in main parameter control. The device establishes a good foundation for the further research of SMDS. 使用结果表明,该注射装置总体方案合理,主要参数控制精确,为分段沉积/雕铣成形新工艺的进一步研究奠定了良好的基础。
