Method of processing set of stream in view of configuring time-sensitive network, and time-sensitive network system

A method of processing a set of stream requests in view of configuring a time-sensitive network comprising at least a centralized network configuration entity operably connected to a plurality of end station entities and to a dynamic bridge entity,

• the method comprising, upon obtaining a set of stream requests from and/or to at least part of the plurality of end station entities:
• at the centralized network configuration entity, computing, by the centralized network configuration entity, based on an initial time-sensitive network capability obtained at least from the dynamic bridge entity, an initial time-sensitive network scheduling that sets times of transmission and of reception of packets through the time-sensitive network at least from one end station entity of the plurality of end station entities to another,
• performing a sequence of:
• determining, by an entity performing decision-making which is an entity having full access to information stored at the centralized network configuration entity, based on information related at least to a last computed time-sensitive network scheduling, whether to provide information related to an updated time-sensitive network capability of the dynamic bridge entity to the centralized network configuration entity,
• then, if the information related to the updated time-sensitive network capability of the dynamic bridge entity are to be provided to the centralized network configuration entity, providing the information related to an updated time-sensitive network capability to the centralized network configuration entity, by the entity performing the decision-making, and computing, by the centralized network configuration entity, an updated time-sensitive network scheduling based on the provided information related to the updated time-sensitive network capability and restarting the sequence, and
• if the information related to the updated time-sensitive network capability are not to be provided to the centralized network configuration entity, ending, by the entity performing the decision-making, the sequence, and
• determining, by the centralized network configuration entity, based on at least one computed time-sensitive network scheduling, whether to configure the time-sensitive network according to one of said at least one computed time-sensitive network scheduling or to request an adjustment of at least one stream request in view of configuring the time-sensitive network based on a resulting adjusted set of stream requests,
• the method characterized in that:
• information related to the at least one computed time-sensitive network scheduling comprises at least information related to a value of a figure of merit function representing a degree of success of said at least one computed time-sensitive network scheduling in terms of satisfying at least part of the set of stream requests, and/or
• a plurality of time-sensitive network schedulings having already been computed through previous iterations of the sequence, wherein the determining, by the entity performing the decision-making, whether to provide the information related to the updated time-sensitive network capability to the centralized network configuration entity is further based on comparing a number of computed time-sensitive network schedulings with a predetermined threshold, and/or
• the method further comprises processing, in response to at least one request of the set of stream requests, information related to a degree of success of at least one computed time-sensitive network scheduling in terms of satisfying said at least one request, and wherein the determining, by the entity performing the decision-making, whether to provide the information related to the updated time-sensitive network capability of the dynamic bridge entity to the centralized network configuration entity is based on said information related to the degree of success of said at least one computed time-sensitive network scheduling in terms of satisfying said at least one request.
