seminar topics for cse 2011 Asynchronous Transfer Mode (ATM) Switching

The research paper seminar topics for cse 2011 Asynchronous Transfer Mode (ATM) Switching explains the functionality of ATM- Asynchronous Transfer Mode Switching. The research paper defines ATM. It suggests that ATM does not stand for automatic teller machine. In the telecommunication, it stands for Asynchronous Transfer Mode, in   which data is sent asynchronously.  This mode is another fast packet switching mode. Asynchronous  transfer  mode  (ATM)  is  a  technology  that  has  his  its  history  in  the  development  of  broadband  ISDN  in  the  1970s  and  980s.  Technically, ATM can be viewed as an evolution of pocket switching. The paper describes pocket switching in detail. ATM  is  also  a  set  of  international  interface  and  signaling standards  defined  by  the  International  Telecommunication  Union- Telecommunications  (ITU-T)  Standards  Sector  (formerly  the  CCITT).

The research paper talks in depth the various functionalities offered by ATM. ATM  provides  a  way  of  multiplexing  many  sources  of data  onto  a  common  cells  stream.  Regardless of  speed  of  the inputs.  This  greatly  improves   flexibility,  enabling  provision  of bandwidth  on  demand. ATM  is  a  cell-switching  and  multiplexing  technology  that  combines  the  benefits  of  circuit  switching  (guaranteed  capacity  and  constant transmission  delay)  with  those  of  packet  switching  (flexibility  and efficiency  for  intermittent  traffic).  It  provides  scalable  bandwidth  from a  few  megabits  per  second  (Mbps)  to  many  gigabits  per  second (Gbps).  Because  of  its  asynchronous  nature,  ATM  is  more  efficient than  synchronous  technologies,  such  as  time-division  multiplexing (TDM).

Three types of ATM services exist: permanent virtual circuits (PVC), switched virtual circuits (SVC), and connectionless service (which is similar to SMDS). ATM supports two types of connections: point-to-point and point-to-multipoint.

  1. *High   performance via   hardware switching
  2. Dynamic bandwidth for heavy traffic
  3. *Class- of –service support for media
  4. Scalability in speed and network size
  5. Common LAN / WAN architecture
  6. Opportunity for simplification via VC architecture
  7. International standard compliance


The research paper concludes on a note that ATM  is  a  technology  that  can  handle  all  types  of traffic  ( voice,  video  and  data)  multiplexed  on  the  same  network  . In  an  ATM  network  band  width  can  be  reassigned  in  real  time  to different  traffic  based  on  demand.  ATM  is  the  only  technology  common   to  all  environments   from  LAN  to  GAN .
