Abstract: The disclosure relates to methods and products for processing stream requests. Upon obtaining the stream requests, an initial TSN scheduling is computed at a CNC based on an initial TSN capability obtained from a dynamic bridge (DB). Then, a loop is started. At each iteration, it is determined, based on information related at least to the last computed TSN scheduling, whether or not to provide information related to an updated TSN capability of the DB to the CNC. If it is decided to provide said information, the CNC computes, based on said information, an updated TSN scheduling. Else, the loop is exited. It is determined, based on at least one computed TSN scheduling, whether to configure the TSN according to one of said at least one computed TSN scheduling or to request an adjustment of at least one stream request.
