actual bandwidth 中文意思是什麼
actual bandwidth
解釋
實際帶寬-
Generally, the designed channel spacing of itu - t standard in wdm systems is from 0. 8nm to 1. 6nm, which is much larger than the spacing required by actual communication bandwidth. for example in lightwave transmission systems, a sghz channel occupies only 0. 04nm at the wavelength band of 1. 55 n m. thus, most of the bandwidth in the actual transmission systems may be wasted
Itu - t標準中wdm系統設計的通道間距為0 . 8nm - 1 . 6nm ，這遠遠大於實際使用的通道帶寬，例如一個帶寬為5ghz的通道在1 . 55 m波段只佔據了約0 . 04nm的波長范圍，因而導致大部分的帶寬被浪費。 -
However, the combination of atm will serve to realize on - demand bandwidth allocation according to the required qos and the actual traffic condition
利用atm技術來傳送這些業務時，就能夠根據所需要的服務質量（ qos ）級別和需要傳輸的實際業務量來按需分配帶寬。 -
In addition, dba scheme over sla is discussed, based on the implementing of dba in actual system of epon. the scheme supports multiple services and provides different bandwidth service guarantees for different service such as fixed, guaranteed and extended bandwidth service. in this paper, the software designing of epon is presented
另外，基於實際epon系統中動態帶寬分配演算法（ dba ）的實現，本文還探討了滿足用戶等級需求（ sla ）的演算法，演算法支持多業務並為不同類型的業務提供不同的帶寬服務保證，譬如:固定帶寬服務、保證帶寬服務、競爭帶寬服務。 -
Also it is discussed how to improve loading performance and the actual results using invariance theory. by the feedforward signals of velocity and acceleration, it is expected to expend the bandwidth to 15hz or even higher and reduce the additional torque at 80 percent. in this thesis, i mainly explored the design theory of ehsls and made a lot of experiments on subsystems and the whole system
本文的目的就是設計、調試帶有彈簧桿緩沖結構的單通道電液伺服加載臺，通過試驗比較、驗證不同控制演算法的工程實際效果；分析和研究應用結構不變性原理如何改善加載系統的動態性能，目的是通過引入速度和加速度的復合前饋信號將系統的動態頻帶提高到15hz左右，並且有效的抑制力加載系統固有的多餘力矩，抑制比要達到80以上。 -
We derived theory for abstraction of bandwidth resource and characterization of system capacity for multi - class fading system. bandwidth resources allocated to a user can be abstracted as effective bandwidth, determined by the user ’ s source data rate and target bit error rate. system capacity can be characterized by a theoretical bound. simulations show that actual system capacity is close to the theoretical bound
為一個用戶所分配的帶寬資源被表示為有效帶寬，用戶對數據速率和比特誤碼率的要求決定了對有效帶寬的要求。利用有效帶寬的概念來描述系統的用戶容量並給出了系統容量的理論界限，進一步地，還得到了系統存在發射功率限制時的容量界限。 -
Linux is a well known os of its open source code and better security. after the deep analysis of network and traffic control mechanism in linux kernel, we finally design and implement a prototype of vpn gateway based on diffserv under linux using unified modeling language ( uml ) from object - oriented perspective. at last, we construct an actual test environment, and the test results indicate that our prototype can not only implement the main functions of ipsec family, but also support the qos of vpn based on the application with good functions of shape and bandwidth traffic control
Linux是一個基於開放源碼的操作系統，也是目前認為比較安全的操作系統，本文最後在對linux內核中的網路和流量控制機制進行深入分析和研究的基礎上，從面向對象的角度，運用標準建模語言uml ，設計和實現了一個基於區分服務的vpn網關原型，並且構建了一個實際的實驗和測試環境，對系統進行了測試，測試結果表明：原型系統在實現ipsec協議族主要功能的基礎上能夠給予用戶基於應用的qos保證，具有較好的流量整形和帶寬控制功能。 -
We also proposed a new call admission control ( cac ) scheme for cdma cellular system that incorporates adaptive power control and mmse multiuser receiver and support multi - class traffic. the call admission control scheme is based on estimation of othercell interference and implemented distributively in each cell. capacity determined by the admission control agrees with the actual system capacity in the simulation. the scheme can achieve high bandwidth utilization and guarantee qos requirements of all the users at the call level
為此，提出了呼叫確認策略，以保證系統中不同業務的所有用戶的qos 。呼叫控制策略在每一小區分佈地進行，通過估計其它小區的干擾確定小區的可用有效帶寬，再根據小區當前的負載決定是否對呼叫請求給予確認。呼叫確認控制可以在呼叫級保證用戶的qos 。 -
Because localization of vrml2. 0 on moving functions and more embodiment of vitality and reality, i use java language. bcause it has points of mutuality, safety and credibility, smallness and agility, facing object, distributed network communications, multithreading and so on, and makes up difference between bandwidth and m anagement ability, and transmitts rich and colorful and alternant media on actual bandwidth condition
由於vrml2 . 0版本語言在運動功能上的局限性，同時也為了更好體現逼真性、生動性的特點。我引入了java語言。由於它具有廣泛移植性，面向對象，交互性，分散式的網路通信，安全可靠，小巧靈活，多線程等一系列優良性能，同時彌補了帶寬與處理能力之間的差距，可在當前的帶寬狀態下傳送豐富多彩及互動式媒體。
