Path shortening in a wireless mesh network
First Claim
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 reaching the mesh portal and having a corresponding signal strength indicator;
generating from among the advertising mesh points an ordered group of parent access points ordered based on the respective metrics, the ordered group 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, andsending to each of the parent access points a 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 minimum interframe spacing for forwarding a wireless packet received from the mesh point.

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.

10. An apparatus comprising:
-
a wireless mesh interface circuit configured for receiving 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 reaching the mesh portal and having a corresponding signal strength indicator; and a parent selection circuit configured for generating from among the advertising mesh points an ordered group of parent access points ordered based on the respective metrics, the ordered group 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; the parent selection circuit further configured for generating, for output via the wireless mesh interface circuit 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 minimum interframe spacing for forwarding a wireless packet received from the apparatus. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus comprising:
-
means for receiving 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 reaching the mesh portal and having a corresponding signal strength indicator; and means for generating from among the advertising mesh points an ordered group of parent access points ordered based on the respective metrics, the ordered group 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; the means for generating further configured for generating, for output 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 minimum interframe spacing for forwarding a wireless packet received from the apparatus.
