According to the mil - std - 188 - 220b protocol of american army , data packets can be relayed and forwarded automatically by nodes in network . the network can detect the change of topology in internal system and assure the information to be sent to the destination node in connective network . furthermore , it comprises of the radio data transmitting network for some equipments such as tactical data terminal and computer so on 本质上，它属于无中心的自组织分组无线网，按照美军战术互联网“数字消息传输设备子系统互操作标准” ( mil - std - 188 - 220b协议) ，通过节点对数据分组的自动中继转发，使网络能够自动探测到系统内部拓扑结构发生的变化，保证信息能达到网络中所有连通的节点，为战术数据终端和计算机等设备提供无线数据传输网络。
By choosing bus structure as the main channel of soa system , the enterprise ’ s it environment will be changed to soa effectively . so we name this bus as enterprise service bus ( esb ) . in this thesis , a systematic survey of eai comes to being and development research is given firstly , and then the study objectives of this thesis are presented 通过选择总线结构作为soa系统消息传输的主干道,使企业的业务架构转向soa ,为未来业务的变化奠定良好的基础架构,因此,我们称之为企业服务总线( enterpriseservicebus )本文首先介绍了企业应用集成( eai )的发展与主流eai技术的原理与应用范围,在企业应用集成的的多个层次上重点对soa的体系结构进行了剖析和研究,提出了基于esb的解决方案。
Design message oriented middleware involves in many technologies . to guarantee the reliability when transforming message , transaction processing , release mode are the key questions when implementing message oriented middleware and the methods to implement them will impact the middleware ’ s performance directly 消息中间件设计涉及的技术范围很广,其中消息队列处理、事务处理、发布模式等是消息中间件实现过程中保证消息传输可靠性的关键问题,它们的实现方法对中间件性能有直接的影响。
Then the thesis describes the implementation of the network engine in detail . we describe the implementation of the software development interface , the encapsulation 、 compression and encryption of the data packet as well as the ensurement of reliability of the data transmission . we also use some uml diagram to describe the key algorithm of the implementation 接着论文具体描述了网络引擎的设计和实现,主要包括用户接口,网络数据包的封装、压缩、加密以及网络消息传输过程中的可靠性保证、次序性保证和优先级保证等功能的实现,并采用uml图对其中的关键算法和思想进行了描述。
This protocol specifies behavior of communication participants and guarantees exactly - once delivery of messages in any kind of failure situations . by exploiting key implementation techniques , mta system is then enhanced in the following two aspects : first , network and system resource usage is optimized ; second , adaptability and manageability of mta is improved 在保障消息传输可靠性的前提下，我们对mta的实现中的一些关键技术作了分析和研究，对mta的实现进行了改进和完善，使其能够更好的更充分的利用系统资源，网络资源，并且提高了消息传输代理的适用性和可管理性。
In the next articles , to create this elaborate e - business dialogue , i will describe how to create reliable asynchronous messaging between the partners , how to bind to back - end systems with the public processes , how to create the public processes and i will also show you what tools are needed and how to install them 在接下来的文章中，为了创建这个精致设计的电子商务对话，我将描述如何在合作伙伴之间创建可靠的异步消息传输，如何将后端系统与公共流程进行绑定，如何创建公共流程，然后我还将说明需要哪些工具以及如何安装这些工具。
First of all , the paper introduces the overall structure of the mac protocol using the multi - hop communication mode , to fulfill the requirement of wsn in collision avoidance , energy efficiency and scalability to the change in network , bandwidth utilization , latency , throughout and fairness 协议采用周期性睡醒机制、 rts / cts的握手机制、适应性侦听以及消息传输等机制,在节省能量的总前提下,有效地减少了延迟、避免冲突,保证网络流量,与传统的数据链路层协议相比,具有明显的优越性。
Aiming to the wireless communication problem of automatic measurement and forecast system , the paper brings forward an scheme that using the sm ( short message ) transmits the collecting data in system , it is one of the services belonging to gsm wireless network which development is fastest in the communication field in latest years 本文针对我国水情自动测报系统的无线通信问题，结合近年来通信领域发展最快的gsm无线网络技术，提出了一种应用gsm短消息传输水情数据的自动测报系统设计方案。
