Patent number: 11979862Abstract: Providing for time sensitive networking (TSN) traffic in high density deployments is described. An access point (AP) is a high density deployment receives a message identifying another AP as a TSN neighbor and also detects a TSN device within an area covered by the APs. This arrangement may cause traffic interruptions for the TSN traffic between the TSN device and the APs. In order to prevent disruption in TSN traffic, a TSN time slot and a resource unit (RU) is determined for each of the APs, and the TSN traffic is communicated between the various devices in network according to the determined TSN time slot and RU.Type: GrantFiled: September 1, 2022Date of Patent: May 7, 2024Assignee: Cisco Technology, Inc.Inventors: Akram I.
