this thesis expatiates the total design of the service unit network architecture, the demarcation and function of the module, and the service provided for users . in the real-time data transport service based on service unit network architecture, my main task is accomplishing the service of real-time data transport based on service unit network architecture . therefore, this thesis focuses on the characteristics of real-time data, the processing of the real-time data in the traditional network and service unit network architecture 本文詳細闡述了服務元網絡體系結構原型主機的總體設計、模塊的劃分、各模塊的功能以及為用戶提供的服務。本人的主要工作是完成服務元網絡體系結構中的對實時數據傳輸服務的功能實現(xiàn)。因此,本文中對于實時數據的特性,傳統(tǒng)網絡中對于實時數據的處理,以及服務元網絡體系結構中對于實時數據的處理都進行了深入的研究。
