1. A method comprising:
- receiving, by a mesh point, mesh advertisement messages from respective advertising mesh points of a wireless mesh network having a mesh portal, the mesh portal having a wired connection to a wired network, each mesh advertisement message specifying a corresponding metric for the corresponding advertising mesh point reaching the mesh portal and having a corresponding signal strength indicator;
generating by the mesh point from among the advertising mesh points an ordered group of parent access points each providing a corresponding mesh link for reachability for the mesh point to the mesh portal, the ordered group ordered based on the respective metrics specified in the respective mesh advertisement messages, the ordered group starting with a first parent access point chosen by the mesh point based on the first parent access point having a corresponding optimum metric for reaching the mesh portal and chosen independent of the corresponding signal strength indicator, andsending by the mesh point to each of the parent access points a corresponding registration message identifying a corresponding specified priority based on a corresponding position in the ordered group, for use by the corresponding parent access point in selecting a corresponding distinct minimum interframe spacing for forwarding toward the mesh portal a wireless packet received from the mesh point via the corresponding mesh link.

Abstract
In one embodiment, a method includes a mesh point receiving mesh advertisement messages from advertising mesh points of a wireless mesh network having a mesh portal with a wired connection to a wired network. Each mesh advertisement message specifies a corresponding metric for reaching the mesh portal and has a corresponding signal strength indicator. An ordered group of parent access points, ordered based on the respective metrics, is generated from among the advertising mesh points, starting with a first parent access point having a corresponding optimum metric for reaching the mesh portal and independent of the corresponding signal strength indicator. A registration message is sent to each of the parent access points identifying a corresponding specified priority based on a corresponding position in the ordered group, for use by the corresponding parent access point in selecting a minimum interframe spacing for forwarding a wireless packet received from the mesh point.
