20120230346 | Ethernet Switching - A scheduler in an Ethernet switch and method for scheduling and queuing received unicast packets. The scheduler determines a destination address and a traffic priority of a received packet, and searches for a stored association between the destination address and an interfacing port of the Ethernet switch. When a stored association is found, the received packet is scheduled and queued in one of the priority buffers of the output buffer in an associated interfacing port according to the received packet's traffic priority. When no association is found, the scheduler floods the received unicast packet in a flooding buffer in every interfacing outgoing port of the Ethernet switch. The flooded packet may be scheduled as low priority traffic, or may be prioritized in relation to other flooded unicast packets based on each flooded unicast packet's traffic priority. | 2012-09-13 |
20120230347 | METHOD AND USER TERMINAL FOR RECEIVING MULTICAST CONTROL CHANNEL CHANGE NOTIFICATIONS - The embodiments of the present invention disclose a method and user terminal for receiving multicast control channel (MCCH) change notifications, which include: obtaining the transmission time of an MCCH change notification; and when the MCCH change notification is not received during one MCCH modification period, receiving, according to the transmission time of the MCCH change notification, the MCCH change notification at least N times, wherein N is the preset reception times of the MCCH change notification. In the present invention, the efficiency of receiving MCCH change notifications by user terminals is improved, and the probability of processing MCCH change notifications falsely due to too many network identifiers in a physical downlink control channel (PDCCH) is reduced. | 2012-09-13 |
20120230348 | DATA BLOCKING SYSTEMS FOR NON-ARBITRARY NETWORKS - A network device includes a memory with a first queue and a second queue. A timing module generates a first priority timing signal or a second priority timing signal based on a clock signal. The clock signal is shared between the network device and other network devices in a non-arbitrary network. The network device includes a deblocking shaper or a blocking shaper. The deblocking shaper (i) forwards first protected data from the first queue, and (ii) generates a deblocking signal based on a first frame signal and the first priority timing signal. The blocking shaper (i) forwards one of second protected data and unprotected data from the second queue, and (ii) generates a first blocking signal based on a second frame signal and the second priority timing signal. A selector module selects the first frame or the second frame based on the deblocking signal and the first blocking signal. | 2012-09-13 |
20120230349 | COMMUNICATION METHOD AND COMMUNICATION DEVICE AS WELL AS COMPUTER PROGRAM - Communication performed within a network including a plurality of communication stations is provided, in which when an access control is performed so that communication timing of a packet can not collide with that of another station by detecting a signal which is transmitted from another station, “a header area processed not to become easily an error such as a physical layer header portion of a packet” which is transmitted from a communication station is made to have at least information which is required for extracting information in a payload of the packet and a field for controlling an access reservation of transmission of a packet which is generated as a result of transmission of another packet so that processing using the field can be performed. | 2012-09-13 |
20120230350 | SIGNAL DEMULTIPLEXER, SIGNAL MULTIPLEXER, AND SIGNAL MULTIPLEXER/DEMULTIPLEXER - A signal demultiplexer includes a conversion unit that converts a format of a high speed signal transfer frame output from a terminating unit into a format of a converted frame; a parallelization unit that parallelizes the converted frame and outputs a predetermined number of data columns; and a separating unit that separates plural low speed signal transfer frames from the predetermined number of the data columns. The conversion unit converts the format of the high speed signal transfer frame into the format of the converted frame by delaying a signal storing area using first and second overhead areas, to include an “i” th tributary slot among the predetermined number of the tributary slots assigned to the signal storing area into an arbitrary “i” th data column among the predetermined number of the data columns, and to align front positions of the predetermined number of the data columns. | 2012-09-13 |
20120230351 | Streaming Segmentation And Reassembly In Asynchronous Transfer Mode Communications - Systems, methods, and apparatuses are provided that enable streaming of ATM cells between a transmit/receive data processing application and a transmission convergence function. Data to be segmented into an ATM cell is received at a SAR engine, and provided to a transmission convergence function, with the first cells transmitted to the transmission convergence function before the SAR function receives an end-of-packet indication from the optimization engine. Data received at a transmission convergence function is placed in a received packet queue at the SAR function, with packets provided to an application after a start-of-packet indication is received, and before an end-of-packet indication is received, at the SAR function. | 2012-09-13 |
