introduction
DTM combines the two basic technologies used to build high-capacity networks—circuit and packet switching—and therefore offers many advantages.
It also provides several service-access solutions to enterprises, residential and small offices, content providers.
DEFINITION
DTM, Dynamic synchronous Transfer Mode, is a broadband network architecture based on circuit switching augmented with dynamic reallocation of time slots.
DTM provides a service based on multicast, multirate channels with short set-up delay.
WHY DTM?
For maximize transmission capacity the DTM protocol was developed.
DTM is designed to increase the use of fiber's transmission capacity and to provide support for real-time broadband traffic and multicasting.
It is also designed to change the distribution of resources to the network nodes dynamically.
THE DTM ADVANTAGE
DTM was developed in an effort to combine the simple and real-time traffic-supporting properties of circuit-switching technology with the dynamic resource handling properties of packet-switching technology.
DTM forms a transport-network architecture that enables high transfer capacity with dynamic allocation of resources.
CONCLUSION
As the bottlenecks of networks move from the transfer capacity of the network links to the processing capacity of the network nodes, DTM aims to reduce network complexity to provide full access to available bandwidth.
