Embodiment Construction

[0021] Referring to the drawings, in which like numerals indicate like elements, FIG. 1 is a diagram illustrating a wireless mesh network 100 according to an exemplary embodiment.

[0022] According to an exemplary embodiment, a wireless mesh network may be a collection of mesh points (MPs) interconnected with wireless links. Each MP may typically be an access point, but may also be a station or other wireless node. For example, a wireless mesh network may employ a full mesh topology or a partial mesh topology. In a full mesh topology, each node (or mesh point) can be directly connected to each of the other MPs via wireless links. In a partial mesh topology, a mesh point may be connected to some of the other mesh points in the mesh network but not necessarily to all other mesh points in the mesh network.

[0023] In an example, the wireless mesh network 100 shown in FIG. 1 , the mesh points MP1 , MP2 , and MP3 may be connected to each other via wired links or wireless links....

Abstract

Various embodiments are disclosed relating to traffic prioritization techniques for wireless networks. Different priorities may be applied to uplink traffic and downlink traffic at one or more nodes or mesh points (MP1, MP2, MP3) in a wireless network, for at least some traffic. In another example embodiment, a first set of QoS parameters may be used for uplink traffic while a second set of QoS parameters may be used for downlink traffic for one or more nodes within a wireless network, for at least some traffic. According to another example embodiment, local or intra-cell traffic may be prioritized differently than inter-cell traffic for a mesh point within a wireless meshed network, for at least some traffic. For example, local or intra-cell traffic may be prioritized over inter-cell traffic for a mesh point within a wireless meshed network (100).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 60 / 684,935, filed May 26, 2005, entitled "QoS Parameter Delivery Mechanism for Meshed Wireless Networks," which is hereby incorporated by reference. Background technique [0003] The rapid spread of wireless local area network (WLAN) access and the growing demand for WLAN coverage are driving the installation of a large number of access points (APs). However, most wireless networks today provide little or no Quality of Service (QoS). Although QoS may refer to different concepts, QoS may, for example, include providing different service levels or qualities for different types of traffic. Draft specifications from the IEEE 802.11e task group have proposed a set of QoS parameters for use between access points and stations. See, eg, Tim Godfrey, "Inside 802.11e: Making QoS A RealityOver WLAN Connections," CommsDesign, December 19, 2003. [0004] The...
