A markov model is used for calculation of dcf throughput. it is disclosed that the key parameters are the number of contending stations and the length of contention window. the maximum throughput and the best parameters are offered by theoretical analysis
對dcf部分，利用markov模型推導網路吞吐量性能，指出競爭站點數和競爭窗口長度是關鍵性能參數，從理論上給出最大吞吐量和最優參量值。 -
A qos - support protocol, m - dcf, and its schedule model are proposed. by providing different contention window for different classes, the higher class frames the higher access probability. the simulation proves that m - dcf has better performance than dcf protocol on system throughput, discard ratio, frame discard ratio of higher classes, average access delay of different classes
提出了為不同等級幀提供不同競爭窗口的改進型dcf ： m - dcf協議，並給出了m - dcf的調度模型，通過採用不同的競爭窗口，為不同n西安電子科技大學博士學位論文:無線局域網和ip服務質量關鍵技術的研究的應用提供了不同的接入概率，保證了qos ;模擬結果證明了m一dcf在系統吞吐率、丟包率、高等級業務丟包率、不同等級業務的平均接入時延等方面都優于dcf協議。 -
In this paper, on the basis of previous research works, the ivth system model is studied, and results are compared with the ii th one, and we get expressions for the transfer probability of the customers pij, the mean number of customers in the steady state m, and the mean detained time of the customers in the system w. so far, the theory foundation of the contention - collision elimination access mode has been established for its application
其中競爭?沖突淘汰存取方式類、類、類、類系統模型的數學建模已經完成。本文就類系統模型進行了數學建模，提出了顧客轉移概率p _ ij 、平穩狀態下系統平均隊長（ ? ） 、顧客平均等待時間w等的算式。 -
Based on the study of hfc mac protocol over contention / reservation scheme, an efficient method, which worked on random contention and polling model has been proposed in this article to meet the needs of a multi - priority service access control system
摘要研究了基於爭用預約機制的混合光纖同軸寬帶接入網媒體接入控制協議原理，提出了隨機爭用與周期查詢排隊系統相結合的終端申請接入方式，使不同優先級的終端申請能以不同的控制機制實現接入。 -
This model is primarily used in environments where there is heavy contention for data, so that the cost of protecting data with locks is less than the cost of rolling back transactions if concurrency conflicts occur
此模型主要用於以下環境：對數據存在激烈爭用，使得用鎖保護數據的成本少於在發生並發沖突時回滾事務的成本。
