TELECOMMUNICATIONS ARCHITECTURE

 The telecommunications network to help ITS should be painstakingly planned. A typical engineering for such a network is known as a various leveled or layered/layered design, which show numerous similitudes to the progressive arrangement of street networks. In particular, telecommunications networks can be considered as comprising of four levels:

backbone (spinal column) 

backhaul (transportation) 

distribution 

access 

Utilizing roadways as a relationship to telecommunications, the backbone level is like key intercity/interstate thruways. It permits shipping (pulling) a lot of information between a set number of fixed distribution focuses. As in street networks, the various layers of the correspondence network are interconnected. Fiber optic links are usually utilized for this level. 

The capacity of the vehicle layer is to move (pull) a lot of information (which actually require an enormous transfer speed) from the primary network (backbone) to the Traffic Control Center. Customarily it is off the interstate/roadway network - and can be given by a specialist organization, for example, a telecommunications organization (TelCo). 

The distribution layer looks like the blood vessel street framework in a street network. This layer ordinarily doesn't deal with huge volumes of information. Its principle reason for existing is to give different purposes of essence to improve accessibility. 

At last, the access layer seems as though a metropolitan or private street network or the link that interfaces the TV with the reception apparatus attachment - which gives nearby wiring to access the various gadgets on the network.
