Presentation On ATM

3. Introduction
ATM means Asynchronous transfer mode.
ATM (Asynchronous Transfer Mode) is a switching technique used
by telecommunication networks that uses asynchronous time-division
multiplexing to encode data into small, fixed-sized cells.
This is different from Ethernet or Internet, which use variable packet
sizes for data or frames and transported over virtual connections.

4. Architecture of ATM
Architecture of ATM, there are a range of components and
connections involved in the ATM networks. All connections in
the ATM network are point-to-point, with traffic being switched
through the network by the switching nodes.
Two types of networks are included in the ATM architecture.
Public Networks and Private Networks.

6. ATM Layers
ATM is a layered architecture allowing multiple services—voice, data,
and video—to be carried over the network. It consists of three layers:
the Physical layer, the ATM layer, and the ATM adaptation layer.
To manage this layers have some planes. Such as:
 Management Planes
Plane Management
Layer Management
 Control Plane
 User Plane

8. ATM LAN
The ATM technology can be adapted to local area network called
ATM LANs.
The high data rate of technology (155 to 622 Mbps) has attracted th
e attention of designer who are looking for greater and greater spee
d of LAN.
ATM technology supports different type of connection between tw
o end user. Its support permanent and temporary connection.

9. ATM LAN Emulation
ATM technology can be adapted to local area network call ATM
LAN’s.
The high data rate of technology (155 to 622Mbps) attracted the
attention of designer who looking for greater & greater speed of
LAN.
LAN emulation.

11. ATM LAN Architecture
Pure LAN :In a pure ATM LAN, an ATM switch is used to connect stati
ons in the LAN.
Legacy LAN : In a legacy ATM LAN, stations on the same LAN can exc
hange data at the rate and format of traditional LANs.
Mixed LAN: In a mixed architecture LAN, it allows the gradual migrati
on of legacy LANs onto ATM LANs by adding more and more directly
connected stations to the switch.
