Value specified in the icmp echo request controls packet fragmentation 值控制數(shù)據(jù)包的分段。
Hope that friends can watch the download , there is a detailed introduction in the control packets 希望不能收看的朋友下載使用,控件包里面有詳細的介紹和使用說明。
Especially no additional cost exists if services have started before the network topology is formed , except the size of control packets grows 特別是當節(jié)點加入網(wǎng)絡之前服務已經(jīng)啟動時,除了控制報文大小的變化以外,不會造成額外的控制開銷。
To supply the gap of current network protocol used in tele - medical monitoring systems , according to a complete life signal monitoring system based on mobile platform , this dissertation presents life signal wearable monitoring protocol . firstly , designing the proper format of data packet and control packet on the basis of life signal ’ s specialty to enhance the transmitting efficiency . secondly , describing the protocol in the method of formalization , designing the flow of the protocol and implementing it by coding . thirdly , analyzing the performance of the protocol on both local machine and lan , debugging and modifying the software to meet the require 首先,根據(jù)生命信號的特點,本著提高傳輸效率的原則,設計了生命信號數(shù)據(jù)報文和控制報文的合理格式;其次,采用形式化方法對協(xié)議進行了描述,設計了協(xié)議的工作流程并編碼實現(xiàn);再次,在單機和網(wǎng)絡環(huán)境下進行了性能分析,調(diào)試修改軟件并使其達到設計要求。
While a control packet is processed at each switching node , an all optical light path is set up dynamically for the corresponding data packet . switching node architecture and scheduling algorithm have great influence on packet loss rate in obs network . this paper proposed a port modularized scheduling policy that combines these two aspects , with the aim of reducing burst packet loss rate 其中嚴格的端口模塊化策略可以避免m p p交換結(jié)構的內(nèi)部阻塞,在單核心節(jié)點的網(wǎng)絡上使丟失率降到0 ,但不適用于多核心節(jié)點的多跳網(wǎng)絡;修改的端口模塊化算法通過設置合適的參數(shù),平衡各個節(jié)點上調(diào)度資源的使用,在全網(wǎng)達到較低的丟失率。
