協議中利用分層拓撲結構來組織和管理應用層組播網路中的節點，在此基礎上構建滿足流媒體數據傳輸對延遲、帶寬要求的組播路徑。 -
Specifically, for the first time all factors impairing tcp performance are identified based on network protocol hierarchy, i. e., lossy wireless channel at the physical layer ; excessive contention and unfair access at the mac layer ; frail routing protocol at the network layer, the mac layer and the network layer related mobile node ; unfit congestion window size at the transport layer and the transport layer related asymmetric path
Tcp是一種面向連接的可靠傳輸層協議，最初是針對有線網路設計的。由於有線網路鏈路可靠性高，傳統tcp認為丟包和亂序是由網路擁塞所導致。然而，在manets中，眾多非擁塞因素導致了丟包和亂序。 -
The hierarchy of controlling instruments, from higher to lower, is application program, platform, the instruments driver dll, visa, operating system and protocol level of the communication
平臺的上層是測試應用程序，平臺以下有儀器驅動層、 visa層、操作系統層和通訊協議層。 -
Abstract in order to solve the problems of conventional resource discovery framework, a hierarchy - based model was discussed, which combined super - peer model and contact node, a membership join protocol was introduced, and a resource discovery algorithm was proposed based on time to live ( ttl ) limit and cache list
摘要為了解決傳統資源發現機制不能很好地適應網路狀態、可擴展性較差等問題，在超級節點模型的基礎上，結合聯系節點，建立了一種基於層次結構的網格模型，設計了成員加入協議，給出了基於跳數限定、緩存列表的資源發現演算法。 -
