Asynchronous Transfer Mode (ATM) offers services to three different types of technologies

Question one :

Asynchronous Transfer Mode (ATM) offers services to three different types of technologies: Constant Bit Rate (CBR), Unspecified Bit Rate (UBR) and Available Bit Rate (ABR). Each technology has its pros/cons when dealing with ATM.

For this debate, you will take a position on which of these technologies is preferred for data transmission.

To complete this Discussion:

Post: Submit an initial post in which you examine UBR, CBR and ABR technologies.
Choose one of these as the preferred method for transmitting data when bit-rate and minimum quality of service are top priorities and defend why this technology is the best of the three.
