Offers such standard features as qos quality of service technology including proprietary adaptive rate control and real - time auto repeat request 像sony其他會議系統(tǒng)一樣, pcs - tl50提供諸如包括專有的適應(yīng)率控制arc和即時汽車重復要求arq的qos服務(wù)的品質(zhì)技術(shù)這樣標準的特性。
Ensure a tighter coupling between the business processes and the delivered it services , as well as the expected qos quality of service , by streamlining the end - to - end communication process 通過簡化端到端的通信流程,確保業(yè)務(wù)流程和交付的it服務(wù)之間具有更強的耦合性以及期望的服務(wù)質(zhì)量quality of service , qos 。
This paper proposes an end - to - end utilization control architecture and an ic - eat integration control for end - to - end aperiodic tasks algorithm , which features a distributed feedback loop that dynamically enforces the desired utilization bound on multiple processors . ic - eat integrates admission control with feedback control , which is able to dynamically determine the qos quality of service of incoming tasks and guarantee the end - to - end deadlines of admitted tasks 在這樣的系統(tǒng)中,每一個任務(wù)由多個子任務(wù)組成,子任務(wù)之間有著前驅(qū)后繼關(guān)系,形成一個執(zhí)行鏈chain ,并分階段依次運行于不同的cpu上,比如:一個監(jiān)控任務(wù)需要經(jīng)過以下3個子任務(wù)的處理:傳感器采樣數(shù)據(jù)傳輸本地數(shù)據(jù)顯示,而每個子任務(wù)分別運行在不同處理機上。
