This paper will study under layered real - time scheduling problem, which is based on the theory of mas ( multi - agent system ). first, we research the structure model of mars, then an uniform model based on han ( hierarchical agent networks ) is proposed, which can unify all sorts of model ; second, the communication model of mars has been studied, then we propose high level communication model and under layered network topology model, and they are the same with mars ; three, ground on above, a real - time cimunication protocol for mars - - - - - rtcmr has been presented. in this paper, we study the under layered real - time scheduling protocol of rtcmr, which include real - time process scheduling and real - time message scheduling
本文首先研究了多智能體機器人系統結構模型，提出了多層次智能體網路一體化模型，該模型對各種結構模型分類進行了統一；然後對多智能體機器人系統的通信模型進行了研究，提出了適用於mars的高層通信模型和底層網路拓撲；在此基礎上，提出了基於多智能體機器人系統的實時通訊協議? ? rtcmr ，本文對rtcmr的底層調度協議進行了研究，包括實時任務調度和實時報文調度，提出了sp ts協議系統，建立了sp ts演算法的數學理論模型， sp ts協議系統在實現了實時任務的絕對時限保證的同時也實現了底層實時報文傳輸的絕對時限保證，實現了實時任務調度和實時報文調度的統一，最後，提出了基於sp ts協議的spp tsp統一控制結構，並給出了該結構的統一調度petri網模型。 -
Firstly, unlike other technologies that verify security at high - level protocol, verifying security at ip level is transparent to applications and end - users that don " t have to be modified even if there is any change at ip level. secondly, another conspicuous advantage is that it can be used on any machine that uses ip protocol to communicate. no matter ipsec runs on routers, on firewall machines, on various application servers, and on end - user desktop or laptop machines, it can verify security of network transmission
首先，在通信協議底層對數據傳輸提供安全保護與其它在高層協議中提供安全保護的技術不同，在ip層提供安全性保護對應用程序和終端用戶都是透明的，不需要應用程序、其它通信層次和網路部件做任何改動；其次， ipsec的另一個顯著特點是它幾乎可以運行在使用ip協議進行通信的任何機器上，不論是運行在路由器、防火墻主機、各種各樣的應用服務器上，還是運行在終端用戶的個人計算機或筆記本電腦上，它都能提供一定的安全保障；最後，利用ipsec實現虛擬專用網是目前通過internet實現企業內部網的主要解決方案之一。 -
Epics / ca supports tcp / ip protocol, ca software package are both setup on high level clients and servers. users can read data from ioc databases on different node by transparent communication by epics / ca tools, so that data sharing is realized. epics / opi on the clients provides ioc database creating tools and gui developing tools and device monitor software package
Epics的ca支持tcp ip協議， ca軟體包分別安裝在高層客戶機和作為服務器的前端機上，使用epics ca工具，用戶可以從客戶機上以透明通訊方式直接讀取駐留在網路不同節點上ioc數據庫中的實時數據，實現了網上的數據共享。 -
Based on the analysis of shortcoming and limitation in traditional contract net protocol, the author provides a new cooperation strategy - improved contract net protocol, which improves the efficiency of the system and the quality of the task completed by introducing evaluated parameters and expanding the statements of tenderee and bidder. also, a bidder - selected strategy is presented. selecting a proper interaction way and expanding kqml can make kqml support high - level, complicated and multi - bout interaction and cooperation, and can realize the improved contract net protocol
為實現改進的合同網協議，還需要對agent的通信方式進行選擇並需要對agent的交互語言? kqml進行原語級的擴充，以彌補kqml中有關任務交互原語的缺乏，使kqml支持agent間關于目標、任務的高層次、復雜、多回合的交互協作，進而實現改進的合同網協議。 -
The controller area network ( can ) is a serial communications protocol which efficiently supports distributed realtime control with a very high level of security
控制器局域網（ can ）為串列總線通訊協議，能有效地支持具有很高安全等級的分散式實時控制。 -
Besides the coding specification, avs also developed the file format and real - time transport protocol payload format specifications to enable the application of avs - m video in various services. this paper reviews the high - level coding tools and features of the avs - m coding standard as well as the file format and payload format standards
為了便於在各種實際應用系統中使用avs - m ，還制定了相應的文件格式第九部分第一子部分和avs - m實時傳輸協議real - time transport protocol ， rtp打包格式第八部分第一子部分。 -
As the application of distributed computing is used much more widely ， distributed database becomes a significant part of information management it avoids a lot of disadvantages of conventional centralized database ， and is applicable to many situations distributed database is a set of data which is the unity logic ， but in fact these data is located on different sites it is of high availability ， easy expansibility ， high concurrency ， high efficiency and etc in distributed system ， data redundancy is a method to improve the speed of query and the availability of system distributed query should shield the lower level details of data redundancy from end users ， distributed transaction should ensure data from disaccord this paper introduces basic conceptions of distributed database firstly ， discusses distributed transaction and concurrent control ， describes the development prototype mysql ’ s characters ， architecture and executive mechanism ， then shows the skeleton model of dpsql and exposes the strategy and algorithm of distributed query and distributed transaction ， at last analyzes the extra expenses and response delay of distributed processes this paper exposes the implementation mechanism of distributed query and distributed transaction emphatically distributed query uses the strategy of “ read one ， write a11 ” s0 in such a system if user ’ s requests are read - - only for the most part and the distribution of data redundancy is plausible ， efficiency is very high distributed transaction uses two - 。 phase commit protocol to ensure the consistency of global data ， which has less communication overhead
分散式查詢需要向用戶屏蔽數據冗餘分散的底層細節，分散式事務處理要保證全局數據完整，這都是傳統集中式數據庫不曾面臨的問題。本文首先介紹了分散式數據庫的概念性問題；接著討論了分散式事務涉及的定義及演算法；然後描述了dpsql的原型mysql的特性、結構和執行機制；繼而給出了dpsql的梗概模型，闡述了實現分散式查詢和分散式事務處理的策略及演算法；最後分析了進行分散式處理給系統增加的額外開銷和客戶端的額外響應延遲。本文重點描述了分散式查詢和分散式事務處理的實現機制，分散式查詢採用」讀一個寫全部」的本地優先策略，在讀操作頻繁的系統中，只要庫的分佈合理，單機效率極高，幾乎無任何附加開銷和延遲，而以整個系統的角度看來，吞吐量就更是優于單機系統；分散式事務處理採用兩階段提交協議，通信次數較少並能確實保證副本一致。
