Then , by introducing a simple route selecting algorithm in chooser , a capacity - consistent restoration path set in one flooding wave can be obtained , so avoiding the multiple flooding waves in conventional algorithms 同時以時鐘驅(qū)動的方式驅(qū)動網(wǎng)絡(luò)中各參與恢復進程的節(jié)點發(fā)送消息包,以確保所形成的恢復路由集合為ksp集合。
Based on the analyzing and summarizing the status of domestic and oversea capp system , to satisfy manufacturing enterprise requirements for capp functions , this dissertation brings forward the concept of cooperative capp supporting double language . this dissertation has also presented thorough study on some key technology , such as process language automatic translation , process workflow management , process cooperative workout , process route selected and product planning decision - making and so on 本文在分析和總結(jié)目前國內(nèi)外capp系統(tǒng)研究現(xiàn)狀的基礎(chǔ)上,從滿足現(xiàn)代制造企業(yè)對capp的功能需求出發(fā),提出了支持雙語的協(xié)同capp的概念,并對其中的若干關(guān)鍵技術(shù)? ?工藝語言的自動翻譯、工藝工作流管理、工藝協(xié)同編制、工藝規(guī)劃與生產(chǎn)調(diào)度協(xié)同工藝決策等進行了深入的研究。
A fundamental issue in multicast communication is how to determine an efficient message route ( multicast routing ) . at present , internet only provides best effort services , considering hop times or delay in route selecting . in order to support qos , we should consider other parameters such as band width , delay , delay jitter , loss rate and so on 目前的internet只提供盡力傳送服務(wù),在進行路由選擇時一般只考慮網(wǎng)絡(luò)路由的跳數(shù)或時延,但為了支持各種qos需求,還應該考慮如帶寬、時延抖動、丟失率等參數(shù)。
The approach has three merits : it optimizes both the route selected for service class by traffic engineering in network layer and the service class selected for the user services by network plan in service layer , it ensures quantitative qos for the user service in diffserv , it achieves high resource utilization , and achieves better performance with less cost for the user service and selected route 它們都可使網(wǎng)絡(luò)資源得到充分利用和使網(wǎng)絡(luò)服務(wù)質(zhì)量得到較大提高,從而可作為解決當前ip網(wǎng)絡(luò)資源匱乏問題和qos保證能力不高問題的方法。 diffserv機制目前在ip網(wǎng)絡(luò)中得到了廣泛的支持,但diffserv不能提供定量的qos保證,因此,不能被用于傳輸實時的多媒體應用。
