在次世代網際網路中,有愈來愈多的應用程式需要即時性的資料傳輸以及群播的服務。 整合服務網路 (Integrated Services Network) 和 差別服務網路(Differentiated Services Network) 就是為了滿足這些需求而產生的。 在整合服務網路的架構中,對每個資料流提供了端點對端點的服務品質保證。另一方面,在差別服務網路的架構中,對一些具有相同性質的資料流提供了服務品質保證,同時也較適合在骨幹網路上傳輸。
在這篇論文中,我們提出了一個在區域網路提供整合服務,在骨幹網路提供差別服務的整合環境。我們將會討論到如何在兩種不同型態網路之間轉換服務的種類以及如何在這個整合架構下提供群播服務的解決方法。

In next generation Internet, there will be more and more applications that require real-time transmission and multicast services. To fulfill these requirements, Integrated Services (IntServ) and Differentiated Services (DiffServ) are thus proposed. The IntServ architecture provides an end-to-end QoS guarantee on a per-flow basis. The DiffServ architecture, on the other hand, provides QoS guarantee to aggregate of flows, and is more scalable for backbone networks.
In this thesis, we propose an integrate environment in which local access networks provide IntServ while backbone networks provide DiffServ. Issues on how to map service classes between these two types of network and how to provide multicast services are discussed and possible solutions are proposed.
