What is ATM WAN?

What is ATM WAN?

A wide-area network (WAN) technology, asynchronous transfer mode (ATM) is a transfer mode for switching and transmission that efficiently and flexibly organizes information into cells; it is asynchronous in the sense that the recurrence of cells depends on the required or instantaneous bit rate.

What is ATM in telecommunication?

Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by ANSI and ITU-T (formerly CCITT) for digital transmission of multiple types of traffic, including telephony (voice), data, and video signals in one network without the use of separate overlay networks.

Which interface is used for connecting switches in ATM?

The interface between ATM switches is called the network-to-network interface (NNI).

What is ATM topology?

An experimental general topology local area network based on Asynchronous Transfer Mode (ATM) is described. This network is intended to be used to support multiservice traffic. The provision of guarantees of quality of service to various traffic types is an important feature of the network.

How does ATM works in networking?

Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is similar to an Internet service provider (ISP) and it is the gateway through which all the various ATM networks become available to the cardholder or in other words (the person wanting the cash).

Is the interface between a user and an ATM switch?

The interface between an ATM switch and an end user is called a User to Network Interface (UNI), which is the interface between a public ATM carrier and a customer’s switch.

How does the ATM works?

ATMs require consumers to use a plastic card—either a bank debit card or a credit card—to complete a transaction. Consumers are authenticated by a PIN before any transaction can be made. Many cards come with a chip, which transmits data from the card to the machine.

What is ATM in computer network?

ATM is independent of transmission medium, they maybe sent on a wire or fiber by themselves or they may also be packaged inside the payload of other carrier systems. ATM networks use “Packet” or “cell” Switching with virtual circuits. It’s design helps in the implementation of high performance multimedia networking.

What is ATM (Asynchronous Transfer Mode)?

Asynchronous Transfer Mode (ATM): It is an International Telecommunication Union- Telecommunications Standards Section (ITU-T) efficient for call relay and it transmits all information including multiple service types such as data, video or voice which is conveyed in small fixed size packets called cells.

What is a virtual path in ATM?

A virtual path can be created end-to-end across an ATM network, as it does not routs the cells to a particular virtual circuit. In case of major failure all cells belonging to a particular virtual path are routed the same way through ATM network, thus helping in faster recovery.

What is the size of an ATM cell?

As information is transmitted in ATM in the form of fixed size units called cells. As known already each cell is 53 bytes long which consists of 5 bytes header and 48 bytes payload. Asynchronous Transfer Mode can be of two format types which are as follows:
