Abstract: Methods and systems for low complexity interference cancellation in multichannel optical transmission. Local or self-iteration is performed one or more times between an expected propagation decision feedback equalizer and a soft demapper. Following local iteration, a soft decision forward error correction decoder determines bit log-likelihood ratios, which are fed back to the expected propagation decision feedback equalizer and soft demapper for further self-iteration. Global iteration involving the decoder can also be performed one or more times before a bitstream is decoded.

Abstract: A data transmission method includes detecting a delay between a source end and a sink end; determining a to-be-used second path when a first path currently used to transmit a packet is determined to be a congested path; determining a delay difference between the first path and the second path based on a delay of the first path and a delay of the second path; and sending one or more to-be-sent packets to the sink end through the second path based on the delay difference.

Abstract: A fault information processing method implemented by a first interface with a physical layer (PHY) chip and a media access control layer (MAC) chip, includes, after receiving first fault information sent by a second interface communicating with the first interface, sending by the PHY chip second fault information to the MAC chip, where the first fault information indicates that the second interface detects a fault, and the second fault information indicates that the fault is from the second interface. Because the PHY chip has received the first fault information, a link between the PHY chip and the second interface is normal. Because the MAC chip can normally receive the second fault information, it indicates that communication between the PHY chip and the MAC chip is normal. The fault information processing method is used to determine the fault from the second interface.

Abstract: The present disclosure provides a cabinet and a heat dissipation system. The cabinet includes: an operating compartment, disposed on one side of a heat dissipation substrate, where the operating compartment is configured to accommodate a server; and a heat dissipation compartment, disposed on the other side of the heat dissipation substrate. Both the heat dissipation compartment and the operating compartment share the heat dissipation substrate as a compartment wall. The operating compartment is separated from the heat dissipation compartment by using the heat dissipation substrate. The heat dissipation compartment accommodates multiple heat dissipation fins, and the multiple heat dissipation fins are connected to the heat dissipation substrate. An air intake vent is disposed in a first compartment wall of the heat dissipation compartment, and an air exhaust vent is disposed in a second compartment wall of the heat dissipation compartment disclosure.

Abstract: A processor includes a program block dispatcher, an instruction cache group, and an instruction engine group. A plurality of instruction caches in the instruction cache group are in a one-to-one correspondence with a plurality of instruction engines in the instruction engine group. In a method, the program block dispatcher determines, based on an instruction processing request for processing a first instruction set, a first instruction engine for processing the first instruction set; and determines, based on the one-to-one correspondence between the instruction engines and the instruction caches, a first instruction cache configured to cache the first instruction set. The program block dispatcher sends a program counter in the instruction processing request to the first instruction cache. The first instruction engine obtains the first instruction set from the first instruction cache, to execute an instruction in the first instruction set.
