ALG技術白皮書1 概述 1.1 產生背景 在應用層協議中,有很多協議都包含多通道的信息,比如多媒體協議(H.323、 SIP等)、FTP、SQLNET等。這種多通道的應用需要首先在控制通道中對后續數 據通道的地址和端口進行協商,然后根據協商結果創建多個數據通道連接。在NAT 的實際應用過程中,NAT僅對網絡層報文的報文頭進行IP地址的識別和轉換,對于 應用層協議協商過程中報文載荷攜帶的地址信息則無法進行識別和轉換,因此在有 NAT處理的組網方案中,NAT利用ALG技術可以對多通道協議進行應用層的報文信 息的解析和地址轉換,保證應用層上通信的正確性。 在傳統的包過濾防火墻中,也會遇到類似問題。由于包過濾防火墻是基于IP包中的 源地址、目的地址、源端口和目的端口來判斷是否允許包通過,這種基于靜態IP包 頭的匹配雖然可以允許或者拒絕特定的應用層服務,但無法理解服務的上下文會 話,而且對于多通道的應用層協議,其數據通道是動態協商的,無法預先知道數據 通道的地址和端口,無法制定完善的安全策略。ASPF利用ALG技術便可以解決包 過濾防火墻遇到的問題,實現對多通道應用協議的動態檢測。 綜上所述,ALG和NAT、ASPF特性的配合使用,可以解決這些特性遇到的應用層 協議的多通道問題,進而可以協助網絡設備實現整體的網絡安全解決方案。 1.2 技術優點 ALG和NAT、ASPF等特性配合使用,為內部網絡和外部網絡之間的通信提供基于 應用的訪問控制,具有以下優點: z ALG 統一對各應用層協議報文進行解析處理,避免了 NAT、ASPF 特性對同 一類報文應用層協議的重復解析,可以有效提高報文轉發效率。 z ALG 的狀態檢測是基于應用層協議的,能夠監聽每一個應用的每

在電子設計中一定會用到各種元器件的原理圖和封裝圖,每個人在使用過程中可以自己創建或者在網站下載或者網上購買,但是所有的封裝庫混在一起比較混亂,命名規則也五花八門。長此以往導致自己使用很麻煩,所以本人根據元器件的封裝類型,約束了封裝的命名規則,便于查找和使用。本人致力于將所有常用的元器件封裝做一套完整的封裝庫,以便于大家使用。另外對于3D封裝,一般是借用其他人的封裝庫而創建的,由于本人不是機械設計出生,部分3D封裝尺寸可能不是很正確望見諒。對于直插的排阻可以使用SIP封裝,本人會在后續的資料中上傳。電阻內容較少,不設下載積分。后續資料會需要少量積分,也是希望大家能夠喜歡并給與鼓勵。如果能打賞一二就萬分感激了。

MotioninterfaceTM is becoming a "must-have"function being adopted by smartphone and tablet manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in applications such as gesture commands for applications and phone control, enhanced gaming, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets into powerful 3D intelligent devices that can be used in applications ranging from health and fitness monitoring to location-based services. Key requirements for Motionlnterface enabled devices are small package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application specific performance programmability-all at a low consumer price point.

PrefaceDuring the past years, there has been a quickly rising interest in radio access technologies for providingmobile as well as nomadic and fixed services for voice, video, and data. The difference indesign, implementation, and use between telecom and datacom technologies is also becoming moreblurred. One example is cellular technologies from the telecom world being used for broadband dataand wireless LAN from the datacom world being used for voice-over IP.Today, the most widespread radio access technology for mobile communication is digital cellular,with the number of users passing 5 billion by 2010, which is more than half of the world’s population.It has emerged from early deployments of an expensive voice service for a few car-borne users,to today’s widespread use of mobile-communication devices that provide a range of mobile servicesand often include camera, MP3 player, and PDA functions. With this widespread use and increasinginterest in mobile communication, a continuing evolution ahead is foreseen.This book describes LTE, developed in 3GPP (Third Generation Partnership Project) and providingtrue 4G broadband mobile access, starting from the first version in release 8 and through the continuingevolution to release 10, the latest version of LTE. Release 10, also known as LTE-Advanced,is of particular interest as it is the major technology approved by the ITU as fulfilling the IMTAdvancedrequirements. The description in this book is based on LTE release 10 and thus provides acomplete description of the LTE-Advanced radio access from the bottom up.Chapter 1 gives the background to LTE and its evolution, looking also at the different standardsbodies and organizations involved in the process of defining 4G. It also gives a discussion of the reasonsand driving forces behind the evolution.Chapters 2–6 provide a deeper insight into some of the technologies that are part of LTE and itsevolution. Because of its generic nature, these chapters can be used as a background not only for LTEas described in this book, but also for readers who want to understand the technology behind othersystems, such as WCDMA/HSPA, WiMAX, and CDMA2000.Chapters 7–17 constitute the main part of the book. As a start, an introductory technical overviewof LTE is given, where the most important technology components are introduced based onthe generic technologies described in previous chapters. The following chapters provide a detaileddescription of the protocol structure, the downlink and uplink transmission schemes, and the associatedmechanisms for scheduling, retransmission and interference handling. Broadcast operation andrelaying are also described. This is followed by a discussion of the spectrum flexibility and the associated
