Resource reservation and/or scheduling may take credit-based shaper algorithm/queue behavior, in time sensitive communication, into account. A base station may schedule resources for transmission of time sensitive networking packets based on the state of the credit based shaper queue. The state of the credit based shaper queue may be determined based on real-time credit-based simper assistant information, in an uplink scenario, or output of a simulator of a real-time credit-based shaper queue, in a downlink scenario, or a combination of real-time credit-based shaper assistant information and simulator output.

Provided is a server delay control device for a server in which an OS having a kernel is deployed. The OS includes: a ring buffer managed by the kernel; and a poll list in which information on a net device of a hardware interrupt from an NIC is registered. The server delay control device is deployed in the server and configured to receive a timer interrupt at predetermined specified intervals and monitors a packet arrival and includes: a packet arrival monitoring part configured to check the presence or absence of a packet in the poll list upon being triggered by the timer interrupt to monitor the poll list; and a packet dequeuer configured to, when a packet has arrived, reference the packet held in the ring buffer, and perform dequeuing to remove the corresponding queue entry from the ring buffer.
