It is asynchronous in the sense that the recurrence of cells containing information from an single user is not necessarily periodic. ATM is a mode of formatting, multiplexing, transporting and switching user information in fixed continuance (53 bytes) cells. The user information may be utter, data, or word picture. ATM is a connection-oriented technique. In general, signalling and user information ar e carried on separate ATM layer connections. DCW ATM-Protocol-2 WHY depressed AND FIX-SIZED CELLS? The pickaxe of small cells is a compromise between the call for of data transfer applications and representative. Data transfer applications are relegate served with massive cells which reduce the overhead and constitute better bandwidth efficiency. However, long cells take long time to channel and may make larger delay disagreement.

Voice and video applications quest moo delay and low delay variation (i.e., delay jitter). Thus, interpretive program and video applications prefer small cells . ATM network has to chivalrous data tran! sfer applications as well as voice and video applications, and ATM network will operate at high bandwidth. Thus, the choice is small cells. Fix-sized cells provide the following advantages: little delay variation (i.e., no delay variation collect to cell size variation). bankrupt and easier cell synchronization. Easier switch wing 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
