INTRODUCTION
DTM is a form of circuit switching for fiber-optic networks
DTM employs TDM (time division multiplexing).
DTM channels are simplex to achieve high bandwidth.
The DTM architecture was conceived in 1985 and developed at the Royal Institute of Technology in Sweden
WHAT IS DTM ?
DTM is a broadband network
architecture .
DTM is based on circuit switching
augmented with dynamic
reallocation of time slots.
PRINCIPLE OF DTM
Basic technologies :
Circuit Switching
Time Division multiplexing (TDM)
Channel Establishment
CIRCUIT SWITCHING
Network resources are reserved all the way from sender to receiver before the start of the transfer
Control signalling and payload data transfers are separated
Traditional voice telephone service is an example of circuit switching.
TIME DIVISION MULTIPLEXING
Signals are operate in same
frequency in different time slot.
It’s a base band transmission.
In synchronous TDM time slot are pre assigned.
ADVANTAGE
Increases the use of fiber's transmission
capacity.
Provides support for real-time broadband traffic & multicasting.
Dynamically allocates the distribution of
resources to the network nodes
APPLICATION
Real-time traffic & multicasting required in videos
Transmission of integrated data, both audio & video.
Enterprise Access and Private Data Networking
CONCLUSION
DTM aims to reduce network complexity
DTM provides full access to available bandwidth.
DTM provides a guaranteed quality of service (QoS) for streaming
video services.
