Abstract: A method, an apparatus, and a communication node for suppressing output noises of peripheral component interconnect express (PCIe) devices in optical fiber communication is provided. The communication node includes a PCIe chip and a detection and control circuit connected to a transmitting end of the PCIe chip. The PCIe chip transmits an electrical signal by a transmitter of a first lane. The detection and control circuit detects a differential-mode voltage of the electrical signal. If the differential-mode voltage is lower than a first threshold, the detection and control circuit controls an optical module connected to the PCIe chip not to transmit an optical signal through the first lane of the optical module. When a PCIe system includes the communication node, output noises of the transmitter is suppressed, and a normal optical fiber communication link is ensured.

Abstract: A method for detecting a receive end, a detection circuit, an optical module, and a system are provided, and relate to the field of optical communications. The method includes: transmitting a first detection code pattern to a PCI-E receive end through optical transmission, so that after receiving the first detection code pattern, the PCI-E receive end feeds back a second detection code pattern through the optical transmission; detecting whether the second detection code pattern fed back by the PCI-E receive end through the optical transmission is received; and determining that the PCI-E receive end is in position if a detection result is that the second detection code pattern fed back by the PCI-E receive end through the optical transmission is received.

Abstract: This application discloses a method and an apparatus for adjusting a data sending rate. In the method, when determining that a return time of feedback information of a first data packet has timed out, a terminal reduces a data sending rate of a connection to which the first data packet belongs from a first value to a second value. Then the terminal detects return times of feedback information of a plurality of subsequent data packets after the first data packet and determines a cause of the timeout of the feedback information of the first data packet. The terminal further increases a data sending rate from a current third value to a fourth value when determining that the timeout is caused by a packet loss on a wireless link in a communications link.

Abstract: A packet transmission method and related apparatus are disclosed. A transmit end retransmits a first packet to a receive end and decreases a congestion window and a slow start threshold upon determining that the first packet has been lost. The receive end sends an ACK in response to the retransmitted first packet to the transmit end on receipt of the retransmitted first packet for the first time, where the ACK contains a proactively constructed DSACK option for informing the transmit end that the first packet has been received repeatedly. The transmit end therefore compensates the congestion window and/or the slow start threshold.

Abstract: This application provides a packet sending method, an apparatus and a chip. The method is applied to a terminal, the terminal includes a baseband processor, an application processor, and a communications interface. The baseband processor reports information about a first packet to the application processor, where the first packet is a to-be-sent packet discarded by the baseband processor. The application processor transmits a second packet to the baseband processor according to the information about the first packet, where the second packet is the same as the first packet. The baseband processor sends the second packet to a network device by using the communications interface.
