1. An autonomous quality of service provisioning apparatus in a time-sensitive network, the apparatus comprising:
a parameter extraction unit configured to:
receive a packet transmission from a transmitting terminal, and
extract quality of service (QoS) parameters by analyzing intra-packet information, and inter-packet information, the intra packet information includes address information, a packet length and QOS setup information, and the inter-packet information includes an interval between packets, a maximum packet size, and an interval-wise maximum packet number,
a quality of service reservation unit configured to be associated with a controller that manages and controls resources of the network to request the controller to reserve resources according to the extracted QOS parameters; and
a time synchronization unit configured to perform time synchronization between a master clock of the controller and a slave clock to maintain time synchronization of the parameter extraction unit in the slave clock synchronized with the master clock of the controller,
wherein the parameter extraction unit is further configured to:
analyze the received packet based on the time synchronization; and
analyze intra-packet information and inter-packet information based on the time synchronization to ensure accurate extraction of intra-packet and inter-packet information for autonomous QoS provisioning.
