Abstract: A heat dissipation apparatus, a connection structure, and an electronic device. A first heat sink is in thermal contact with a first heat-generating device on a first component, and a second heat sink is in thermal contact with a second heat-generating device on a second component. The first heat sink and the second heat sink are communicated through a pipeline (120), and the three are filled with a cooling medium. Heat generated by either of the first heat-generating device and the second heat-generating device may be transferred to the cooling medium in the heat sink through the corresponding heat sink, and the heat is dissipated outward through a surface of the heat sink.

Abstract: A communications network delay variation smoothing method, an apparatus, and a system are disclosed. The method includes: clearing, by a local device, a forward delay threshold and a reverse delay threshold when an initialization time starts; and when determining that a maximum value between a real-time forward delay value corresponding to a current service flow fragment and a reverse delay threshold corresponding to the current service flow fragment is greater than a current value of the forward delay threshold, replacing the current value of the forward delay threshold with the maximum value. In this way, after the initialization ends, a delay threshold after the initialization ends is determined and is applied to delay compensation, thereby significantly reducing a bi-directional asymmetric delay variation, and avoiding a problem of abnormal user communication that is caused when the variation exceeds a limit.

Abstract: This application provides an isolation and recovery method and related network device for a case when one or more physical layer apparatuses (PHYs) in a flexible Ethernet group (FlexE group) are faulty. In the method, if a network device determines that a first overhead block corresponding to each current available PHY is stored in a corresponding memory, the network device determines that a FlexE group meets a PHY alignment condition, and starts to simultaneously read cached data from all memories. Therefore, there is no need to insert local fault LF code blocks to all clients, and there is no need to recreate a group. This effectively reduces the impact of a faulty PHY on client services carried by a normal PHY.
