lower layer protocol 中文意思是什麼
lower layer protocol
解釋
低層協議-
It is an ordinary datagram service, providing consistent service for the higher layer and general interfaces for the protocol on the higher layer by using the bearer network on the lower layer so as to adapt the higher layer to the lower - layer network. this makes the higher - layer protocol unrelated to the lower - layer bearer network
Wdp是一般數據報服務，使用下層承載為上層提供一致的服務，為上層協議提供通用介面，使其上層適配到指定的下層承載網路中，這使得上層協議可以與下層承載網路無關。 -
4. the application sublayer, which converts the information format between the user and the lower protocol layer. 5. the user sublayer. the key part, function block is the assurance of the interoperation of it
這部分的重點內容是功能塊，它是ff實現互可操作的保證，也是ff不同於其他總線的獨特之處，作者作了詳盡的分析。 -
Lower layer protocol forthe q3 and x interface
Q3和x介面的低層協議框架 -
Based on the detail of traditional tcp, the reason of the low throughput and impaired performance of tcp in wireless networks is given, then some solutions are proposed based on the transmission control principle. moreover the impactions of protocols in the lower layers including mac and routing protocol on tcp in ad hoc network are discussed in detail, and 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 investigated. in this environment an integrated wireless tcp, called iwtcp, is presented to solve the problem about higher bit error rates and disconnection, which emphasizes on the analysis and simulation, the results show that the scheme can greatly improve the performance of tcp, and the realization of iwtcp is given at last
文中主要針對分散式adhoc網路，由於其獨特的網路結構，所以我們在分析tcp基本原理的基礎上，討論了傳統tcp在無線環境中吞吐量較低、性能惡化的原因，並闡述了無線環境對擁塞控制機制提出的要求，同時就adhoc網路中低層網路協議（ mac層和網路層協議）對tcp的影響進行了詳細的分析，強調tcp和mac層機制間的相互作用、路由協議中造成adhoc網路中tcp性能降低的原因，並針對現有無線tcp方案不能有效應用於有線無線網路的問題，提出了應用在adhoc網路和internet網路互聯環境下的一種綜合性tcp解決方案? ? iwtcp ，重點對該方案的性能進行模擬，從理論上分析了性能提高的主要原因，並證明此機制可在很大程度上提高adhoc網路中tcp的性能，最後給出了iwtcp具體軟體實現方案。
