中文拼音 [lùyóucéngtōngxìn]
路由層通信
英文
router level communication-
In tranditional ip network, only the “ best effort ” service is provided, but the quality of service can not be guaranteed. though the interserv, deffserv and mpls are presented afterward to guarantee the qos for the ip network. but as a layer network, the realization of the qos function need span different layers ( such as rsvp protocol ) in the ip network, which may result in the function iterance and chaos
多媒體和實時業務的出現要求網路能夠提供足夠的qos保證，在傳統的ip網路中只能提供「盡量傳輸」的服務而不能保證服務質量，后來提出的綜合服務模型（ interserv ）以及區分服務模型（ deffserv ）以及mpls技術保證了ip網路上的服務質量，但由於ip網路是層次結構的網路，因此對qos的支持需要跨層（如rsvp協議） ，這就可能引起功能的重復和混亂，而微通信元系統是無層次結構的網路系統，就克服了這些的問題，變得簡單，效率更高。Client supplies complete graphic user interface, accomplishing the management of jobflow and system ; communication agent accomplishes complete communication between client and server by tcp / ip network communication protocol and platform independent data communication protocol ; server supplies full support of jobflow, the superstratum are the jobflow definition subsystem and jnwengine, which are responsible for the definition and execution of jobflow ; the understratum is the network queue system, which realized the schedule and execution of job, thus all kinds of sources in computer network system can be utilized in order to improve execution efficiency and reduce job cost

考慮到不是所有的站點都願意提供中繼服務及平面結構的局限性（在網路規模較大時性能會很差） ，本課題的無線移動自組織網路參考了蜂窩移動通信系統的特點，是一種具有兩級結構的網路。使用專門的無線設備? ? 「無線路由器」構成具有用戶無線接入、無線組網和路由功能的無線互連網路，為移動用戶提供無線接入、路由和中繼服務。 ieee802 . 11b可以提供很高的通信速率，可以提供很好的接入性能，並且支持ieee802 . 11b協議的設備正成普及的態勢，因此成為我們所選擇的鏈路層協議。The mpls technology was raised just in order to make the most of the switching technology in the core of the network and the ip routing technology on the edge of the network. before presenting the solution of the mpls, there are many integration model, the basic method adopted by them were all carry the control information from the ip router, and combine it with the transmition capability and the label switching of the atm switching machine, accordingly constructing a high speed and economic multi layer switching router. but, all these solutions can not communicate and just suit for adapting the atm as the second layer transmiting link, can n ' t work on other interface ( fr, ppp, and ethernet ), this is obviously conflict with the developing way of the based on packet of the internet
多協議標簽交換（ mpls ）技術就是為了綜合利用網路核心的交換技術和網路邊緣的ip路由技術各自的優點而產生的。在mpls技術方案提出之前已有的各種集成模型解決方案所採取的基本方法都是從ip路由器獲取控制信息，將其與atm交換機的轉發性能和標簽交換方式相結合，從而構建成一個高速而經濟的多層交換路由器。但是，各種方案彼此不能互通，而且僅適用於以atm作為第2層的傳輸鏈路，不能工作在其他多種媒體（如幀中繼、點對點協議、以太網）中，這與internet基於分組的發展方向相矛盾。This scheme can avoid the emergency of orphan effectively, and gives a good solution when the node isn ’ t available. the protocol we design is named as soptt, which is shorted as “ self - organize protocol of tree topology ”. the layer of application we design can gather and send data, realize the function of data fusion to avoid the potential communication congestion so that the communication will be more effectively
