A stator for an electric motor is described. An example stator includes a stator core having teeth that are radially arranged about a common central axis of the stator and located in a spaced apart manner from one another. Each tooth has an inward portion and an outward portion. The example stator further includes an electrically transmissive coil of wire that is wound contiguously upon the inward portions of at least a subset of teeth from the plurality of teeth. The stator also includes wedge members that are radially arranged about the common central axis and located intermittently with the plurality of teeth such that each wedge member abuts with the outward portions of adjacently located teeth.

Stator for an electric motor

A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voiceover-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.

AP-local dynamic switching

A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID, acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.

Untethered access point mesh system and method

A method for reassigning flows to cores in a multi-core network device includes receiving a packet flow and periodically determining a packet rate of the flow and the processing load on each of the worker cores. Unassigned flows are assigned to the least loaded core. If an assigned flow has a packet rate that exceeds a particular threshold proportion of the processing capacity of the currently assigned worker core, reassigning the flow to the lowest loaded worker core unless the resulting load would exceed the current load on the currently assigned worker core.

Multicore offloading of network processing

A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID; acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.

In some embodiments, an apparatus includes a network node configured to be included in a set of network nodes operatively coupled to a core network node. The network node is configured to receive a first packet and a second packet from a host device operatively coupled to the network node. The network node is configured to send the first packet to the core network node via a first path of a tunnel between the network node and the core network node. The first path of the tunnel has a first cost. The network node is configured to send the second packet to the core network node via a second path of the tunnel. The second path has a second cost different than the first cost.
