SS7（Signaling System NO.7；簡稱SS7）Networks可將異質的電信網路，加以連結起來，如智慧型網路（Intelligent Networks；簡稱IN）、公眾交換電話網路（Public Switched Telephone Networks；）、整體服務數位服務網路（Integrated Service Digital Networks；簡稱ISDN）、及行動電話網路（Mobile）及個人通訊服務（Person Communication Services）等等，使得處理SS7的技術極為受到重視。
SS7網路傳統的路由方式是在STP內以人工處理的方式來作設定，它的缺點就是沒有動態路由選擇的能力，缺乏壅塞處理的能力，需要俱備平均高承載的傳輸容量。
在本文中，我們提出了動態路由通訊協定DRP（Dynamic Routing Protocol），能夠在SS7網路中使用動態路由的方法，透過動態路由的方式，產生快速變換能力，提高網路效能，有效節省網路資源，增加原有STP的能力。

Signaling System NO.7 has been applied to conventional Public Switched Telephone Networks（PSTN），Integrated Service Digital Networks（ISDN），Broadband-ISDNs，and Mobile Telephone Systems.
The signaling messages are routed by Signaling Transfer Points (STPs). Routing tables in STPs are setup manually. That is, the routing paths including backup paths between any two STPs are pre-determined. In cases of link failure, the routing paths are also changed manually. Due to the importance of SS7 networks, it is necessary to develop a suitable dynamically routing protocol to make SS7 networks more robust.
In this thesis, we develop a dynamic routing protocol (DRP) with OSPF advantages, open algorithm, supporting various computing of distance, dynamic routing, and adapting to hierarchical networks, but it is much simpler than OSPF.
