摘要: 
為了提升差異式服務網路架構的延展性,我們利用以配額(quota)方式分配頻寬,減少了邊際路由器與頻寬仲介者的溝通訊息量也減少在處理頻寬時需要更新資料庫的次數。當網域上的可用頻寬不足已用配額為單位分配時,再利用訊標的方式尋找其他邊際路由器中可利用頻寬,以增加頻寬的利用程度。
經過上述的方式,一方面我們減少頻寬仲介者需要處理的訊息量,另一方面避免使用配額方式分配頻寬所造成的頻寬利用度不佳的缺點。在使系統擁有較佳的延展性時,也同時能有效的利用頻寬。

In order to increase scalable in differentiated service network , we use quota-based to allocation resource in the network domain . By the way we cat not only reduce the communication between edge router and bandwidth broker but reduce the number of update the database when process the request message . We also use token to search available bandwidth in other edge router when the network domain can not allocate bandwidth in unit of quota any more so that we can increase the capability of bandwidth .
In this way , we can really reduce the overhead when the bandwidth broker process the request message and prevent the disadvantage when we allocate bandwidth in the unit of quota . This method let the system have better scalable and also increase the capability of bandwidth .
