分散式多媒體應用資訊系統因為應用目的的不同,而各有其不同的使用者多媒體服務品質(User Multimedia Quality-of-Service, QoS) 要求,意即會有不同等級的服務品質與資源保證 (QoS Guarantees)。因應使用者不同服務品質需求之目的,在整合式網路和差異化服務網路環境中,我們提出一個以使用者為導向之動態服務品質設定與對應的架構 (User-oriented Dynamic QoS Framework, UDQF),並基於使用者的角度進而設計使用者所定義之應用層QoS參數,並與下層之網路層QoS參數作有效之對應。由於網路的流量狀態不斷地改變,使用者的QoS需求也可能提高或降低,因此本論文針對使用者動態調整服務品質,提出使用者為導向之動態服務品質定義與對應策略 (User-oriented Dynamic QoS Specification and Mapping, UDQSM) 以有效解決動態服務品質設定與對應的問題,除此之外,我們亦提出動態服務品質佇列對應 (Dynamic QoS Queue Mapping, DQ2M) 演算法來解決當路由器某個佇列嚴重壅塞而其他佇列低使用率,進而動態充分地利用低使用率佇列資源的問題。
We proposed the Dynamic User-Oriented QoS Framework (DUQF), which provides the effective adaptation control schemes for dynamic QoS specification and mapping based on the combination of DiffServ and IntServ network architecture. A DUQF network consists of a DiffServ WAN and lots of attached IntServ LANs that connect to each other via a RSVP-aware router and a differentiation edge router, respectively. In an IntServ LAN, we designed the User-oriented Dynamic QoS Specification and Mapping (UDQSM) system to adaptively achieve QoS specification and mapping at the application layer. In the DiffServ of DUQF, we proposed the Dynamic QoS Queue Mapping (DQ2M) algorithm to increase the utilization of network resources and find the most appropriate service class that the media packets should map in an edge router of the DiffServ network.
