Centralized network configuration entity and time sensitive network control system comprising same

Abstract

The embodiment of the invention relates to a time-sensitive network control system and a centralized network configuration entity for controlling data traffic in the time-sensitive network control system. In one aspect, embodiments of the present application may provide a centralized network configuration entity for controlling data traffic scheduling of a time-sensitive network, the entity comprising: a receiving unit for receiving flow information about a plurality of traffic flows from a centralized user configuration entity, the plurality of traffic flows are used for transmitting first data sensitive to a time delay in a sub-network and second data insensitive to the time delay; a resource allocation unit that uses the flow information to allocate output port time resources of respective switching entities included in the sub-network, the respective switching entities being used to transmit the first data and the second data; a gate control list generation unit for generating switching gate control list information for controlling the operation of the switching entity and / or sending entity gate control list information for controlling the operation of the switching entity on the basis of the stream information and the output port time resource, and / or sending entity gate control list information for controlling the operation of the switching entity on the basis of the stream information and the output port time resource. The sending entity gate control list information is used for controlling data transmission gates of a plurality of sending entities sending the plurality of traffic flows; and the sending unit is used for sending the switching gate control list information to the switch and sending entity gate control list information to the centralized user configuration entity.

Problems solved by technology

[0007] However, no control technique is disclosed in conventional network systems that allows time-sensitive data to arrive at a receiving entity within a required delay in an environment where time-insensitive data and time-sensitive data coexist.

In other words, conventional network systems cannot meet the required delay while controlling data traffic in an environment where only time-sensitive data is configured or time-sensitive and time-insensitive data are mixed
