  • 近年來,雲端技術已經相當成熟了,在雲端計算技術之下,有很多的資料中心為
    了減少花費,還有為了有效的加強服務品質,許多多媒體應用還有網路很多網路
    服務在網路中的崛起,他們需要高更品質的服務只保證優質的服務,服務品質只
    能保障頻寬,還有藉由先進先去的排成進行調度,面對這種限制之下,我們提
    出,及於軟體定義網路的一個新的軟體框架,這個軟體框架可以即時的降低在網
    路中的延遲時間,並且不僅有保證的頻寬,還有保證的延遲,其中軟體框架包含
    了四個元件,資源監視,路由計算,資源預約,三個部分,如何利用軟體定義網
    路使得能達到更好的服務品質是未來的一個重要議題,我們接下來會在論文中詳
    細解釋.


    In recent years ,The cloud technology development is more and more mature ,Under
    the cloud computing technology,there are a variety of data center in order to
    reduce the cost and to increase the efficiency of the Quality of Service(QoS), Many
    multimedia applications and online services have risen on the Internet,and they
    need high quality services for better guaranteed Quality of Service (QoS) ,Quality
    of Service(QoS) is only performed with bandwidth guarantees and by a well-known
    FIFO scheduling. Facing this limitation , we propose a new software framework that
    based on Software Defined Networks(SDN),OpenFlow.This framework can lower the
    delay time in network in real time ,and not only have guaranteeing bandwidth but
    also have guarateeing delay ,it include source Monitoring,Route calculation,Resource
    reservation ,three part in this software framework ,how to use SDN to have better
    Quality of Service(QoS) become in important issue in the future.we will explain
    more detail in my thesis .
