Brief description of the design of a network of a transmission by packets of the type deterministic

摘要

The networks of the packet-switching transmission deterministic type are those where the various flow of information on the virtual paths are defined in advance for which it requires a reprogramming of interconnection nodes. The advantage of a determinism is that it makes it possible to estimate more easily the time of the maximum delay that can be subjected to the packets in the course of their paths in the network. However, it remains to verify that the network is suitably sized 2 in order to ensure the transmission of the various streams of data with the constraints maximum delay and regularity, imposed by the equipment connected. It proposes a method of the dimensions of the network, with a verification of compliance with these constraints, passing through the determination of the components of the jitter added by the various interconnection nodes of the network, at the level of their different output ports, this determination is made of an incremental manner, by lowering the course of the virtual paths travelled by the various information stream.
