Development of the communication switching;

Aiming at the need of agility of switching in the data communication system, we design the switching matrix net which used analog switching integrate circuit.

The queue strategy and buffer technique are the core of switch matrix design and they are also the main factors in time delay generation of switch matrix.

MPSR P3S is a brand new switch matrix for System 12 Exchange of Alcatel, which is used to replace the aged Digital Switch Network (DSN).

Through constructing a list of nodes information,switching matrix and a list of restricted region,radar informaiton would be introduced into the system more quickly and distributed to nodes which mostly need it,and the bandwidth of the multi-radar netting system would be utilized more efficiently.

In the core node of the OBS network, optical switching matrix is a key component, whose configurating time affects on performance of the network by limiting available duration of data channels.

Define a joint Spectrum of noncommuting matrixes by Curto operator,and discussed the relation ship between the joint spectrum and Xia′s joint spectrum.

Linear operators that strongly preserve commuting pairs of matrices over Boolean algebras;
