Abstract: A method and a system for indoor positioning within a wireless mesh-type network can be applied where a plurality of access points are located in an indoor space. According to the method, any one access point of the plurality of access points receives a request for indoor positioning transmitted by a portable device, wherein the request comprises received signal strength indications (RSSIs) measured and collected by the portable device. The access point compares the measured and collected RSSIs of the request to RSSIs stored in a fingerprinting database to determine a fingerprinting position using a closest match method and the access point provides, to the portable device, the determined fingerprinting position.

Abstract: A method for providing a differentiation in terms of quality of service (QoS) for multiple tenants in a network, by a networking device receives a data packet from a transmitting tenant, and the networking device identifies the tenant and a priority class of the received packet. The networking device then determines one or more color markers to apply to the received packet according to the sending tenant and the priority to be associated with the packet. The networking device then transmits or does not transmit the packet onwards depending on one or more color markers applied to the packet.

Abstract: A method for rerouting traffic by a switch in a software defined networking (SDN) arrangement comprises an additional switch, multiple routing paths between the original switch and the additional switch being preconfigured by a SDN controller. The original switch collects network statistics by transmitting monitoring packets on each of the multiple routing paths and then calculating a round-trip time (RTT) value for each path on the return of the monitoring packets to the additional switch, the two switches functioning together as local controllers. After collection of network statistics from all the multiple routing paths, the original switch selects the routing path with the smallest RTT value and reroutes traffic accordingly.

Abstract: An autonomous positioning system for a mesh network, includes a mobile device receiving a first transmitting signal, a second transmitting signal and a third transmitting signal via the mesh network, obtaining a first, second, third received signal strength indicator (RSSI) corresponding to the first transmitting signal, the second transmitting signal, and the third transmitting signal; a first stationary access point transmitting the first transmitting signal via the mesh network and receives the a first, second, third received signal strength indicator (RSSI) and obtaining a position of the mobile device according to the first, second, third received signal strength indicator (RSSI); a second stationary access point transmitting the second transmitting signal via the mesh network; and a third stationary access point transmitting the third transmitting signal via the mesh network, wherein the first stationary access point receiving the second distance information and the third distance information.

Abstract: A cable interface connection structure includes a jack and a plug. The plug is received in the jack. The jack includes a case, a support body, and a plurality of pins. The pins are received in the support body, and the support body is received in the case. The jack defines two rows of the pins. The plurality of pins in each row is the same. The plug includes two rows of contact terminals. A plurality of contact terminals in each row is the same. The pins are coupled to the contact terminals.
