An apparatus and a method for managing network flow congestion are provided. The method for managing network flow congestion includes: receiving a plurality of packets; identifying whether each packet belongs to a predetermined protocol; distinguishing a plurality of connections of the packets belonged to the predetermined protocol; monitoring a buffer usage of each different connections; and performing a congestion check procedure on the currently monitored connection. In the congestion check procedure, when the buffer usage of the currently monitored connection exceeds a threshold, a congestion processing procedure is triggered.

A passive optical network (PON) includes at least one optical network unit (ONU) at a downstream end and an optical line terminal (OLT) at an upstream end. Each ONU is dynamically allocated with an upstream communication window. During a laser always on (LAO) detection process, when the OLT receives an optical signal from the downstream end within an upstream idle window, the OLT determines that an LAO problem exists. The upstream idle window does not overlap with any upstream communication window. An anomaly detection method for the PON includes: during the LAO detection process, when the OLT receives an optical signal from the downstream end within the upstream idle window, determining, by the OLT, the LAO problem exists. An OLT includes an optical transceiver unit that optically communicates with the downstream end and output a receiving state signal and a control unit that determines whether the LAO problem exists.

A network device and a packet replication method are provided. The network device includes a classification engine, a forwarding engine, and a packet replication device. The packet replication device includes an interface circuit, a replication control circuit, and a storage unit. The interface circuit retrieves a packet of a flow from the forwarding engine and correspondingly outputs a replicated packet to the replication control circuit. The replication control circuit calculates a current rate corresponding to the replicated packet, checks a flow table for a cumulative number of replicated packets of the flow, and determines, according to the current rate and the cumulative number of replicated packets, to forward the replicated packet. The storage unit stores the flow table. The replication control circuit transmits the replicated packet to at least one application engine through at least one communication port for security inspection.

A packet forwarding device and a queue management method are provided. The queue management method is applicable to a plurality of priority queues each associated with a different transmission priority. The queue management method includes: allocating at least one buffer from a free buffer pool to each of the priority queues; monitoring a number of dropped packets of an observation queue of the priority queues; and increasing a number of buffers for the observation queue and decreasing a number of buffers for at least one of the priority queues which has a lower transmission priority than the observation queue, according to the number of dropped packets.

Systems and methods for identifying locations and controlling devices are provided. For example, a user may indicate a location by aiming at the location from multiple positions in a physical space. The user may also identify a controllable device to control by aiming at the device. Example systems and methods include determining a first position within a three-dimensional space, receiving a first directional input, and determining a first ray based on the first position and first directional input. Example systems and methods also include determining a second position within the three-dimensional space, receiving a second directional input, and determining a second ray based on the second position and second directional input. Example systems and methods may also include identifying a location within a three-dimensional space based on the first ray and the second ray.

Position-based location indication and device control

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for resolving erroneous movement signals and for providing navigation instructions. One of the methods includes receiving data from two or more sensors, synchronizing the received data, determining a first subset of the synchronized data from the camera for a particular period of time and a second subset of the synchronized data from the other sensor for the particular period of time, comparing the first subset with the second subset to determine whether the first subset and the second subset indicate an erroneous movement signal, based on determining that the first subset and the second subset indicate an erroneous movement signal, selecting data for one of the sensors based on a sensor priority scheme for the sensors, and resolving the erroneous movement signal based on the selected data for the one of the sensors.

In an asynchronous optical modulation system, a drive circuit may generate a plurality of dither tones in accordance with a predetermined dither frequency ratio. Based on the components of the dither frequency ratio, the optical modulation system may be configured to determine a feedback signal magnitude component that is independent of the delay &#x3c4; and a feedback signal sign component that is also independent of the delay &#x3c4;. A feedback signal that is independent of the delay &#x3c4; can then be reconstructed based on the feedback signal magnitude component and the feedback signal sign component.

Method for providing augmented user interface (AUI). AUI is provided in response to a request. AUI configuration information is received, stored in preference file, and sent to remote server. Remote server receives request from computer to login user. Remote server authenticates user, retrieves and sends preference file to computer. Preference file contains information that allows computer to implement and configure AUI by directing output to AUI component. Remote server sends computer web-based API to enable browser to interface with an AUI application. API can include target callable by event handler to respond to HTML document browsing event by invoking AUI application. Remote server can send computer web-based, native, or browser plug-in AUI application. Computer can provide content rich navigation via API, AUI application and content navigation rules that define plural navigation paths through HTML document. Navigation paths providing AUI functionality to particular type of special needs user or user task.
