时延和时延的抖动是多媒体网络中两个重要的参数，它们与网络的服务质量相关．提出了一种新的网络时延和时延抖动的控制方法——按时服务原则．该方法以虚拟时钟算法为基础，吸收了Ｊｉｔｅｒ－ＥＤＤ算法的优点，能够同时对时延和时延抖动进行控制．同以往的时延和时延抖动控制算法相比，其优点在于：无需为会话建立通信模型，只要是受漏桶（ＲＳ，Ｄ０）限制的会话，那么，该会话在按时服务器组成的网络中就存在一个最大时延Ｔ１，ＭＳ，ｍａｘ．
Jitter of delay and delay are two important parameters in multimedia network, which are related to the service quality of the network. A new control method of network delay and delay jitter is proposed - on time service principle. Based on the virtual clock algorithm, this method absorbs the advantages of Jiter-EDD algorithm and can control the delay and delay jitter simultaneously. Compared with the traditional delay and delay jitter control algorithms, this method has the following advantages: No communication model needs to be set up for the session. As long as the session is limited by the leaky bucket (RS, D0), the session is in a network composed of time servers There is a maximum delay T1, MS, max.
