隨著行動通訊網路不斷的進步,VoIP的技術也越來越受到重視。許多中小企業、學校單位也建立起自己的VoIP局端系統。然而這些單位所建置的局端之間皆是各自獨立運作,無法互相通話。此外VoIP的使用者越來越多的情況下,單位中的局端管理者必須要架設擴充及備援局端解決負載及穩定性問題。將這些局端串聯起來的路由設定也隨著使用者增加而越來越複雜。 本論文提出以網路電信雲端架構方式以簡易的路由設定將各單位之間獨立的VoIP局端系統串聯起來,同時取代各個局端系統中複雜的路由設定。並使用資料庫同步技術,將各單位本地端資料備份到雲端上,使各單位可以使用VoIP雲端租賃服務,並使單位中的使用者即使離開內部網路,仍舊可以享有雲端漫遊的服務。 本論文提出網路電信局雲端服務系統具有以下特色: 1. 快速的路由設定技術 2. 雲端備援機制 3. 雲端漫遊服務 4. 雲端資料備份
With mobile network improvement, VoIP technique is more and more popular. In many companies and schools have started to construct themselves VoIP Server System. However, their System cannot communicate with each other. Furthermore, VoIP user become more, it must to construct extension and redundant servers to solve excessive loading and stable problem. Linking all servers is a complicated issue. In this thesis, using cloud architecture of network communication system links all VoIP Servers with simplification routing. Furthermore, it backs up each local database data by using database synchronization technique to cloud database. And these units can rent VoIP cloud service. Even though VoIP users leave Intranet, they can use cloud roaming service. Some special ideas and new architecture in our research and implementation is listed as below: 1. Easy routing technique. 2. Cloud redundant service. 3. Cloud roaming service. 4. Cloud backup service
