main components in the wap architecture

WAP does not specify bearer services, but uses 2. This interoperability allows developers to focus on creating their applications, without having to worry about the underlying network that will be used. WAP allows end users to access a broad range of content over multiple wireless networks using a common user interface, the WAP browser. The above Figure gives an overview of the WAP architecture, its protocols and components, and compares this architecture with the typical internet architecture when using the World Wide Web. AD FS subnet. A WMI provider is a COM object that monitors one or more managed objects for WMI. Web Applications include two different sets of programs that run separately yet simultaneously with the shared goal of working harmoniously for delivering solutions. current www in the internet offers web pages with the help of HTML and web The main used for connection-oriented service as described in section 10.3.5. The interface defines ways to organize, access, store, and retrieve data. Wireless Application Environment (WAE). following stays with the model as shown in Figure 10.9.The basis for The two major components of .NET Framework are the Common Language Runtime and the .NET Framework Class Library. WAP 2.0 includes a wireless profile of TLS, which allows secure transactions. service to the higher layers of the WAP architecture. To accommodate this change, WAP 2.x has the following new protocol layers: Wireless Profiled HTTP (WP-HTTP). telephony applications, and many content formats adapted to the special The transport layer service access point switched data, such as general packet radio service (GPRS) in GSM. As a result, the WAP protocol stack is divided into five layers − Layers of WAP Protocol. WAP 2.x contains a new version of WML, commonly referred to as WML2; it is based on the eXtensible HyperText Markup Language (XHTML), signaling part of WAP's move toward using common Internet specifications such as HTTP and TCP/IP. Core Network is composed of circuit switched and packet switched functional modules. The Common Language Runtime (CLR) is the execution engine that handles running applications. Because the WAP specification defines the markup language and microbrowser, users can be assured that wireless content will be suitable for their WAP-enabled device. issues here are scripting languages, special markup languages, interfaces to Examples are Special message services, such as short message service (SMS) of GSM, circuit-switched This is achieved using layered design of protocol stack. The driving force behind WAP is the WAP Forum component of the Open Mobile Alliance. WAP-ARCHITECTURE. The Title: WAP-210-WAPArch-20010712-a.PDF Author: Laurie Hilt Created Date: 7/26/2001 12:48:10 PM This allows the WAP applications within the WAE to communicate with external applications, enabling other applications to extend the capabilities of WAP applications, similar to plug-ins for desktop browsers. Tightly coupled to this layer is the next higher layer, if By contrast, an autonomous architecture uses distributed WAPs that usually do not require a … Implementing push functionality using WTA. Stylesheet support is based on the Mobile Profile of Cascading Style Sheets (CSS) from the W3C, and supports both inline and external style sheets. application environment (WAE) offers a framework for the integration of telephony access has been added.WAP does not always force all applications to network can translate HTML into WML. Wireless Transaction Protocol (WTP). Amidst the rise of 4G technology and the emergence of 5G, the world is in the midst of a digital revolution. and compares this architecture with the typical internet architecture when Explain the architecture of WAP technology. In-And-Outs of an Active DAS: Basics, Components, and More. The need to serve wireless systems sans the structural It typically uses the pull approach for requesting content, meaning the client makes the request for content from the server. Hive Web Interface: Hive Hive provides web-based GUI for executing Hive queries and commands Using UAProf, the information delivered to each device can be highly customized. Study Material, Lecturing Notes, Assignment, Reference, Wiki description explanation, brief detail. Wireless Application Protocol (WAP) is a technical standard for accessing information over a mobile wireless network.A WAP browser is a web browser for mobile devices such as mobile phones that use the protocol. At present, all major wireless carriers support the WAP specification. similar way, a special gateway can be implemented to access traditional The WAP transaction layer with its wireless transaction protocol (WTP) No special interface has been scenarios are possible for the integration of WAP components into existing Wireless Session Protocol (WSP). This is not to say, however, that a WAP gateway is not beneficial. In addition to a new protocol stack, WAP 2.x introduced many other new features and services. Two of the main components of the WAP application environment are Wireless Markup Language (WML) and WMLScript. WAP uses XML as the base language for both WML and WML2 (which uses XHTML), making it easy for application developers to learn and build wireless Internet applications. WAP 2.x is based mainly on common Internet protocols such as HTTP and TCP/IP, while WAP 1.x uses proprietary protocols developed as part of the WAP specification. For consistency reasons with the existing specification, the We will also cover the different components of Hive in the Hive Architecture. use the whole protocol architecture. Each layer is accessible by layers above as well as by other services and applications through a set of well defined interface. telephony access has been added.WAP does not always force all applications to for use in wireless networks with narrow-band channels. These gateways not only filter pages but If a bearer in the WAP architecture This component handles application concerns such as security, communications, operational management. Title: WAP-210-WAPArch-20010712-a.PDF Author: Laurie Hilt Created Date: 7/26/2001 12:48:10 PM WAP Components (contd)… WAP Gateway – Encoder: converts WML to binarized WML – Adaptor: provides additional information through HTTP header • Translate HTTP requests to WSP. There are three main components of … This capability was introduced in WAP 1.2, but has been enhanced in WAP 2.x. Simple applications can directly use WDP. Students are typically expected to know the architecture of the CPU and the primary CPU components, the role of primary memory and differences between RAM and ROM. This architecture extends the implementation described in Extending AD DS to Azure. server translates, e.g., signaling of the telephone network (incoming call TLS/SSL layer of the internet has also been adopted for the WAP architecture WTP provides a reliable transport mechanism for the WAP datagram service. including the major network entities: MSC, GMSC, SGSN, GGSN & PCU. This comparison is often cited by the WAP Forum and The physical layer is not shown; it sits below the network layer and defines the physical aspects such as the hardware and the raw bit-stream. The WAP programming model is very similar to the Internet programming model. These servers provide authentication of local identities within the domain. The communication from a WAP gateway to the microbrowser client is over WSP. At last, we will provide you with the steps for data processing in Apache Hive in this Hive Architecture tutorial. It offers similar reliability as Transmission Control Protocol/Internet Protocol (TCP/IP), but it removes characteristics that make TCP/IP unsuitable for wireless communication, such as the extra handshakes and additional information for handling out-of-order packets. In this chapter we continute to refer to it as the WAP gateway; just be aware that both terms are used to refer to the same technology. This wireless telephony application (WTA) These optimizations result in lower overhead for the communication stream. Wireless Telephony Application (WTA). It also makes content transformation easier by incorporating support for XSL stylesheets to transform XML content. The WAP architecture is composed of various protocols and an XML-based markup language called the Wireless Markup Language (WML), which is the successor to the Handheld Device Markup Language (HDML) as defined by Openwave Systems. The UAProf enables a server to obtain information about the client making the request. The architecture permits robust security, swift development, a dedicated framework, simple maintenance, and extended support from a community of developers. The Wireless Application Protocol (WAP) is a worldwide standard for the delivery and presentation of wireless information to mobile phones and other wireless devices. requirements of small, handheld, wireless devices.Figure 10.9 not only shows Wireless Datagram Protocol (WDP). The system has four major components as illustrated above: 1. TheWAP Protocols cover both the application (WAE), and the underlying transportlayers (WSP and WTP, WTLS, and WDP). The two main architectures used in the WLAN environment differ in the extent that the wireless access point (WAP) has autonomy over access, security, and operation. Wireless Profiled TCP (WP-TCP). WAE has two main elements, namely: (a) user agents, and (b) services and formats. In addition, like the other wireless protocols, WTLS incorporates features designed for wireless networks, such as datagram support, optimized handshakes, and dynamic key refreshing. the overall WAP architecture, but also its relation to the traditional internet architecture as shown in Figure 10.9. For data synchronization, WAP 2.x has adopted the SyncML solution. is additionally converted into binary WML for more efficient transmission. There never was a better time for DAS. Figure 11.7 shows the WAP programming model without a WAP gateway: Note that removing it makes the wireless Internet application architecture nearly identical to that used for standard Web applications. telephone network (PSTN), are shown. As outlined in Chapter 10, "Enterprise Integration through Synchronization," SyncML provides an XML-based protocol for synchronizing data over both WSP and HTTP. It provides privacy, data integrity, and authentication between the client and the wireless server. Many other In June 2002, the WAP Forum, the Location Interoperability Forum, SyncML Initiative, MMS Interoperability Group, and Wireless Village consolidated under the name Open Mobile Alliance to create a governing body that will be at the center of all mobile application standardization work. In our previous blog, we have discussed what is Apache Hive in detail. notice the integrated view for the wireless client of all different services; needed for wireless mobile access to the web.
