The main circuit of the control system adopt the configuration of high-frequency link soft-switching,and the controller use the modified PQ technology and wireless technology based on the current disintegration.

It is pointed out that the use of connection-oriented mode is good for QoS, but keeping connectionless service unchanged is harmful.

Integrating the nature of the connectionless Internet with no resource reservation,we propose a novel multi-constrained end-to-end admission control that provides statistical QoS guarantees.

, connectionless, not guaranteed) way to transport data from source to destination, but the user requires that Internet should provide reliable data transportation from the source machine to the destination machine.
