4.  DYNAMIC SYNCHRONOUS TRANSFER MODE
(DTM).
 An exciting networking technology.
 Made to provide high speed networking with
top quality transmission and ability to adapt
the bandwidth to traffic variations quickly.

5.  Transmission capacity of optical fibers is
growing faster than processing capacity of
computers.
 DTM is designed to increase the use of fibers
transmission capacity and to provide support
for real-time broadband traffic and
multicasting.

7.  CIRCUIT SWITCHING :
 In circuit-switched networks, network
 resources are reserved all the way from
sender before start of the transfer,thereby
creating a circuit.
 For eg. Traditional telephone services.

8.  Packet switching:
 Data is divided into packets.
 Each contains address, size, sequence.
 The packets are sent through the network.
 Packet switched networks are based either on
connectionless or connection oriented
technology.

10.  Transmission of data such as audio and video
both in real time.
 High speed communication.
 Increases the use of fibre transmission
capacity.
 Provide support to real time broadband.

11.  Dense wavelength division multiplexing
equipments today carry only few
wavelengths, 40 to 100 wavelengths carried
on one single fiber will be possible in near
future.
 DTM aims to reduce network complexity to
provide full access to available bandwidth.
