9 results about "Buffer overflow" patented technology

Embodiments of the present disclosure provide a data discarding method, a communication device, a communication system, a storage medium, and a program product. The method is executed by a terminal, and the method comprises: discarding a first data packet among at least one packet data convergence protocol (PDCP) data packet, wherein the first data packet is a PDCP data packet that can be first discarded among the at least one PDCP data packet. In the technical solution provided by the embodiments of the present disclosure, a terminal discards a first data packet that can be first discarded among at least one PDCP data packet, thereby reducing the number of PDCP data packets to be processed or transmitted, thus effectively alleviating buffer overflow of the terminal, and also ensuring timely processing and transmission of PDCP data packets among the at least one PDCP data packet other than the first data packet.

One or more aspects of the present disclosure relate to controlling input / output consumption to prevent port congestion in storage networks. A storage array detects initiator port speeds and maps them to storage ports using masking information. The system tracks aggregate IO consumption across connected storage ports, including in NPIV environments where multiple WWNs share a physical host bus adapter port. When consumption exceeds a threshold of the initiator's bandwidth capacity, the system implements IO limiting to prevent overwhelming the initiator with return payload. Using FDMI information, the system identifies WWNs associated with the same physical port and manages bandwidth allocation across initiators through equal or weighted distribution. This prevents switch credit buffer overflow by controlling data transmission rates between storage ports and initiators. The solution addresses traditional single-WWN configurations and NPIV environments where multiple WWNs operate on a single physical port.

Embodiments of this application provide a decoding method. The method includes: obtaining a bitstream of a first coding unit, where the first coding unit is at least one coding unit in a plurality of coding units; determining an end decrease step, wherein the end decrease step is used to update a virtual padding amount of the plurality of coding units; determining the virtual padding amount of the plurality of coding units based on the end decrease step, where the virtual padding amount is used to reduce storage space of a buffer in a decoding device; determining that an encoding mode of the first coding unit in the plurality of coding units is a fallback mode; and decoding the bitstream of the first coding unit based on the virtual padding amount and the fallback mode, to obtain first data. In an encoding / decoding process, the virtual padding amount is considered in the fallback mode, in other words, encoding / decoding is performed based on the virtual padding amount and the fallback mode, and the virtual padding amount may be used to reduce the storage space of the buffer. This reduces buffer overflow in the encoding / decoding process in the fallback mode.
