Embodiments of the present invention provide a memory access method, a switch, and a multiprocessor system. The memory access method includes: receiving, by the switch, a data packet; matching a flow table on the data packet, where the flow table includes at least one flow entry, where the flow entry includes a matching field and an action field, and the at least one flow entry includes a first flow entry, where a matching field of the first flow entry is used to match source node information, destination node information, and a protocol type in the data packet, and an action field of the first flow entry is used to indicate an operation command for a storage device embedded in the switch; and when the data packet successfully matches the first flow entry, performing an operation on the storage device according to the operation command in the action field of the successfully matched first flow entry. In the present invention, a processor in a multiprocessor system accesses a storage device embedded in a switch, so as to reduce and even eliminate a possibility that the processor accesses a remote memory, and reduce a memory access delay.

The present technology relates to a signal processing apparatus, a signal processing method, and a program by which, in reproducing transmitted encoded data in real time, buffer overflow can be prevented from occurring on a reception apparatus side even if it is transmitted with a compression rate of the encoded data being varied in a manner that depends on communication condition. Encoded data including transmitted audio data is buffered by a reception buffer. At this time, the quantity of encoded data buffered by the reception buffer is managed in units of processing according to an encoding method. The present technology is applicable to a real-time content reproduction system utilizing a communication system.

Embodiments of the present invention disclose a method for mapping a packet service onto an optical transport network, including: receiving a packet service message from an access side, and identifying the packet service message by using a first board number of a first line board in which a first egress is located and a first port number of the first egress; sending the packet service message to the first line board corresponding to the first board number; and encapsulating the packet service message that is sent to the first line board, mapping an encapsulated packet service message onto a first optical channel data unit ODU corresponding to the first port number, and sending the first ODU by using the first egress. According to the foregoing technical solutions, cross-connect scheduling of any bandwidth in any direction is implemented based on a packet service, and packet services on different tributary boards share different ODU timeslot or a same ODU timeslot on a same line board.

The invention relates to a method for implementing an industry internet field broadband bus, and in the method according to the invention, a bus controller and respective bus terminals transmit data in their respective time slices to thereby ensure timely and temporally determinist data transmission. Thus the embodiments of the invention implement a high-performance, highly reliable, and highly real-time method for implementing an industry internet field broadband bus. Moreover a transmission medium of the two-wire data transmission network can be a twisted pair or a shielded twisted pair so that the method according to the embodiment of the invention can be applicable to a traditional industry control facility using a bus, and thus can be highly universally applicable.

The method for forwarding a data packet in a network generally has the steps of: forming at least two transit data packets including replicating at least payload data, sequence data and destination data of the data packet; and forwarding the at least two transit data packets along different network paths. The different network paths can lead to an egress node based on the destination data. At the egress node, the received data packets can be compared to stored data to determine whether the transit data packets having the same sequence data have both been received. The received data packets can then be transmitted to the data destination only when it is determined that they are the first one of the pair of transit data packets to be received.

Decoder retrieval timing information, ROI information and tile identification information are conveyed within a video data stream at a level which allows for an easy access by network entities such as MANEs or decoder. In order to reach such a level, information of such types are conveyed within a video data stream by way of packets interspersed into packets of access units of a video data stream. In accordance with an embodiment, the interspersed packets are of a removable packet type, i.e. the removal of these interspersed packets maintains the decoder's ability to completely recover the video content conveyed via the video data stream.

Disclosed are a processing rule modification method, apparatus and device. The method includes: receiving, by a forwarder, rule modification information sent by a controller, where the rule modification information includes rule description match information and action instruction modification information, where the rule description match information is used to determine a to-be-modified processing rule, rule description information of the to-be-modified processing rule accords with the rule description match information, and the action instruction modification information is used to instruct to modify an action instruction specified in an instruction set of the to-be-modified processing rule; and modifying, by the forwarder, when the forwarder determines that rule description information of a first processing rule meets the rule description match information, an action instruction specified in an instruction set of the first processing rule according to the action instruction modification information. The present invention improves efficiency in modifying a processing rule in the forwarder, and reduces occupied communication resources between the controller and the forwarder.
