Therefore this paper proposes the delay equalization algorithm which can both guarantee the qos of high priority traffic and effectively reduce the delay of ubr traffic in broadband satellite network. it is based on the prediction and equalization the delay of vbr or abr traffic so that the saved slots can be allocated to ubr traffic. the approach of dynamic alternation slots between vbr and ubr traffic can improve the mean tdma frame utilization while reducing the delay of ubr traffic
因此本文在基於流量估計的資源調度演算法基礎上，提出了一種在寬帶衛星網路下能夠保證高級別類業務qos ，同時又能夠有效地降低ubr業務時延的時延均衡（ delayequalization ）調度演算法，它是基於對vbr或abr業務時延的預測，均衡時延的方法，保證vbr或者abr業務qos的同時，將節省的時隙分配給ubr業務。 -
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網路的一個重要特徵就是它能提供幾類服務以滿足不同服務質量的要求，這包括：恆定比特率（ cbr ） 、未定比特率（ ubr ） 、可用比特率（ abr ）以及可變的比特率（ vbr ）服務。 -

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
但是這些演算法都集中在為高優先級業務提高qos而犧牲ubr （ unspecifiedbitrate ）業務的平均時延。
