high layer protocol 中文意思是什麼
high layer protocol
解釋
高層協議-
Because of the unique issues in the networks, including mobility - induced disconnection, network partition, high out - of - order delivery ratios and channel errors, the congestion control and the error recovery in the network is challenging. in this environment, the interaction between tcp and mac layer protocols, the affection of route protocols on the performance of tcp and the particular congestion control and error recovery mechanism are first discussed. then a particular transport layer protocol scheme based on the non - feedback mechanism is presented, with emphasis on the analysis and simulation of the key parameter
文中主要討論了兩種不同網路結構中的無線tcp協議改進方案，其一在最後一跳為無線鏈路的網路環境中，針對基本tcp擁塞控制機制存在的缺陷，文中在現有解決方案的基礎上提出一綜合性的方案，其中包括無線鏈路的高誤碼率和連接斷開問題的解決，並重點對方案中出現的交叉層問題進行分析和模擬；其二，考慮的是分散式網路（ adhoc ） ，在文中較為詳細的分析了tcp和mac層機制間的相互作用、路由協議中造成tcp性能降低的因素、 adhoc網路中應採取的特殊擁塞控制和差錯恢復機制，在此基礎上提出了一種採用非反饋機制的解決方案，重點對方案中的關鍵參數進行分析和模擬，分析和模擬結果表明此機制可在很大程度上提高adhoc網路中tcp的性能。 -
