It is asynchronous in the sense that the recurrence of cells containing information from an individual user is not necessarily periodic. ATM is a mode of formatting, multiplexing, transporting and switching user information in fixed continuation (53 bytes) cells. The user information may be utter, data, or playscript picture. ATM is a connection-oriented technique. In general, signalling and user information argon carried on separa te ATM layer connections. DCW ATM-Protocol-2 WHY petite AND FIX-SIZED CELLS? The pickaxe of small cells is a compromise between the ask of data transfer applications and office. Data transfer applications are split served with ample cells which reduce the overhead and constitute better bandwidth efficiency. However, long cells take long time to channel and may accept larger delay disagreement.

Voice and video applications quest crushed delay and low delay variation (i.e., delay jitter). Thus, articulation and video applications prefer small cells. ATM network has to courageous data tr ansfer applications as well as voice and vi! deo applications, and ATM network will operate at high bandwidth. Thus, the choice is small cells. Fix-sized cells provide the following advantages: slight delay variation (i.e., no delay variation delinquent to cell size variation). bankrupt and easier cell synchronization. Easier switch fender management. Better fit to self-routing switching mechanism. The choice of 53 byte cells is a standards-body comprise. Europeans wanted a 32-byte cell with header,...If you want to get a full essay, order it on our website: BestEssayCheap.com
