Abstract: A system and method for fast roaming in one or more enterprise fabric network. The fast roaming involves correlation operations performed in one or more databases managed by control plane of the fabric network to update routing locator entries associated with L2-VNID and L3-VNID in one or more databases when a client moves from behind a first switch to behind a second switch. In some embodiments, the control plane finds the L3-VNID from the L2-VNID. The L3-VNID is used to search for all IP addresses corresponding to a client-MAC. At least new routing locator value that is used in the routing locator entries is provided to the first switch, the second switch, and border nodes associated with the fabric network.

Abstract: Certain embodiments disclose systems and methods for creating a user private network (UPN) based on 11ay technology. Methods of the present disclosure include creating a personal basic service set (PBSS) having a service device and one or more 11ay devices, the service device configured to wirelessly communicate with the one or more 11ay devices in the PBSS, creating a UPN having an access point located in communicative proximity with the service device, and associating at least one 11ay device of the one or more 11ay devices with the UPN, wherein the at least one 11ay device is configured to establish a wireless connection with the one or more 11ay devices using the service device when within a coverage area of the PBSS, and to establish a wireless connection with the one or more 11ay devices using the access point when outside the coverage area of the PBSS.

Abstract: A first wireless access point uses a first radio access technology in a heterogeneous wireless network. The heterogeneous wireless network includes the first wireless access point and a second wireless access point using a second radio access technology. The first wireless access point determines one or more performance characteristics of traffic management and traffic between a first client device and the first wireless access point using the first radio access technology and the second wireless access point using the second radio access technology. The first wireless device (access point or some other network device) calculates one or more traffic indicators based on these performance characteristics. The first wireless device further communicates at least one of the one or more traffic indicators to the second wireless access point. The communicated traffic indicators are for use by the second wireless access point to schedule radio resources of the second RAT.
