Wireless Network for BeginnersWhat is a Wireless Network? When the term ‘wireless networkÙ is used today, it usually refers to a wireless local area network (WLAN). A WLAN connects computers together through radio technology using standard network rules or protocols, but without the use of cabling to connect the computers together.A WLAN can be installed as the sole network in a school or building. However, it can also be used to extend an existing wired network to areas where wiring would be too difficult or too expensive to implement, or to areas located away from the main network or building. The most obvious difference between wireless and wired networks, therefore, is that the latter uses some form of cable to connect computers together. A wireless network does not need cable to form a physical connection between computers. Wireless networks can be configured to provide the same network functionality as wired networks, ranging from simple peer-to-peer configurations to large-scale infrastructures accommodating hundreds of users. Wireless Home Networking BasicsThese days it seems everyone is having a wireless computer network in their home. So you decide to go for that, and you buy a device your friends suggested at the local store. You look at the box. This gizmo is a wireless access point and broadband router whatever that means. You wonder: did I buy the right thing? Is this what I need? How hard is it going to be to set this thing up? Do not worry. You made an excellent choice. With this device you can:
ATM Signaling and Addressing - Part TwoAddressing on the ATM Switch Router The ATM address is used by the ATM switch router for signaling and management functions, and by protocols such as LAN emulation and PNNI. The ATM switch router ships with a preconfigured default address which allows it to function in a plug-and-play manner. You can change the default address if you need to; the main reasons for doing so are listed in the section "Manually Configured ATM Addresses" section on page 2-11. If you do not foresee needing to reconfigure the ATM address, then the details of the following sections might not concern you. ATM Signaling and Addressing - Part OneBecause ATM is a connection-oriented service, specific signaling protocols and addressing structures, as well as protocols to route ATM connection requests across the ATM network, are needed. The following sections describe the role of signaling and addressing in ATM networking. ATM:Traffic Contracts and Service CategoriesATM connections are further characterized by a traffic contract, which specifies a service category along with traffic and quality of service (QoS) parameters. Five service categories are currently defined, each with a purpose and its own interpretation of applicable parameters. The following sections describe the components of the traffic contract, the characteristics of the service categories, and the service-dependent AAL that supports each of the service categories.
