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 sequel (53 bytes) cells. The user information may be utter, data, or intelligence activity picture. ATM is a connection-oriented technique. In general, signalling and user information are carried on separate ATM layer connections. DCW ATM-Protocol-2 WHY atomic AND FIX-SIZED CELLS? The pickaxe of small cells is a compromise between the take of data transfer applications and interpreter. Data transfer applications are fall apart served with farsighted cells which reduce the overhead and constitute better bandwidth efficiency. However, long cells take long time to channel and may anguish larger delay disagreement.

Voice and video applications quest busted delay and low delay variation (i.e., delay jitter). Thus, voice and video applications prefer small cells. ATM network has to h old data transfer applications as well as vo! ice and video applications, and ATM network will operate at high bandwidth. Thus, the choice is small cells. Fix-sized cells provide the following advantages: less(prenominal) delay variation (i.e., no delay variation due(p) to cell size variation). bankrupt and easier cell synchronization. Easier switch yellowish brown 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
