  1. Lkcc, a linux kernel concurrent communication mechanism, uses object transfer protocol to send and receive data 。 in order to improving system processing capability and to response client requests, session mechanism is changed ; because a great of source have several copy, multi - send is added ; because dps often has great load, some emergent message cannot be send duly ; capability of system is depressed, message pri is added to lkcc

    為了改善系統的性能和滿足用戶的需求，將原來otp協議中會話的一一應答改成了組應答方式;由於dps系統的資源存在多個副本，所以在lkcc中加入了組播功能;又因為當系統繁忙時，某些緊急數據得不到優先發送，降低了系統的性能，所以本文又實現了對緊急數據的優先發送。
  2. The concurrent and deployment of the internet and mobile communication led to a new environment known as mobile or nomadic computing

    隨著網際網路的普及和移動通信技術的飛速發展，移動計算成為引入注目的新課題。
  3. By adopting the layered architecture, two - lever state machine, message queue based publish / subscribe pattern and rules expressed in xml, by using technologies involved in activex, xml and distributed components, icall - aldp provides application developer with supports as rule - based flow process, asynchronism and concurrent message process, external system communication - oriented protocol - transform, and dynamic expand of components

    通過使用activex控制項的動態加載機制、連接外部系統的通信協議轉換機制和基於元數據的柔性機制，增強了平臺的可擴展性。在設計和實現中採用了activex 、 xml 、設計模式以及分散式構件等技術，實現了基於規則的流程處理、支持並發與異步的消息處理以及構件動態擴展的功能。
  4. 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。
  5. Firstly, we define the uml semantic of this model element based on uml extension mechanism, including capsule that is a kind of active class to represent the concurrent unit and protocol derived from collaboration, which mainly is used to describe the communication between capsules

    它有著區別于主動對象的語義和表示方法，而協議被定義為一種協作，埠是參與協作的主要角色，通過狀態機定義了埠間消息收發的序列，並隱式地描述了封裝體對象之間的同步要求。
