Atm why asynchronous

So, no matter how small the voice packets are, they always encounter full-sized data packets, and could experience maximum queuing delays. This is why all data packets should be of the same size.

The fixed cell structure of ATM means it can be easily switched by hardware without the delays introduced by routed frames and software switching. Because of this, some people believe that ATM is the key to the internet bandwidth problem.

A virtual circuit or connection must be established before the two endpoints can actually exchange data. After the connection is set up, all cells reach their destination by following the same path.

Each cell comprises a 5 bytes header and a 48 bytes payload, for a total of 53 bytes. Traffic rate can be constant or variable. This makes it easier to bill data usage. An ATM network is less adaptable to a sudden network traffic surge. It functions much like small-packet switched and circuit-switched networks, which makes it ideal for real-rime, low-latency data such as VoIP and video, as well as for high-throughput data traffic like file transfers.

Since all cells have a fixed length, the network traffic is easily predictable, and thanks to the inbuilt clocking of cells, quick cell switching is possible. This ensures that the quality of service levels can be easily guaranteed to the end-user. Actively scan device characteristics for identification. Use precise geolocation data.
