Asynchronous Transfer ModeAsynchronous transfer mode is a process or switching technology which help fortelecommunication network. This technology is useful for asynchronous time-divisionmultiplexing encode into small unit cells. This technology is converting voice data into packetform and sharing data from one device to another (Schieber and et.al., 2018). ATM provide datalink layer service that running the operating system physical link. ATM network provide differentservices and support the quality of service and requirement of applications. There are different technologies used Asynchronous transfer mode for transmitting packet fromone device to another (Lan and Tang, 2017).Constant Bit Rate (CBR)- Constant bit rate is term which useful for telecommunication andrelated to quality of services (Zhao and et.al.,2018). It is an encoding method and always kept thebit rate same and opposed to variable bit rate. It is difficult process for encoding data withinwindows media format. The size and bit rate of encoded stream is known as priorencoding(Keshav, 2018).Pros: Streaming media file transfer.Fixed size used such as 128 or 320 kbps.Cons:It is performing limited connection.Unspecified Bit Rate (UBR)- unspecified bit rate is a non -real application which is not requiredfor maximum bound on transfer delay and cell(Schieber and et.al., 2018). This bit rate is look likeVariable bit rate which used for connection and transport variable in the system. This systemdoesn't have reliance on time synchronisation(Schieber and et.al., 2018). Cons:The Least priority jobs.It Doesn't promise just tries to transmit packets.Available Bit Rate (ABR)- Available bit rate provide the best efforts transport services which helpfor controlling the entire mechanism of available bandwidth to traffic originator(Schieber andet.al., 2018). This rate use resource management provide feedback and control the traffic sources.Pros:Normal traffic conditions.
