    摘要： This application provides a PFC storm detection and processing method. The method includes: A first network node performs priority-based traffic control PFC detection on a first port queue of a first port, and determines that a first preset condition is met, where that a first preset condition is met includes: detection is performed in N consecutive first time segments, and when the detection is performed in each first time segment, a quantity of first PFC frames sent by the first port queue to a second network node is greater than a first threshold, and a quantity of one or more data packets received by the first port queue from the second network node is less than a second threshold, where the first PFC frame is used to indicate the second network node to suspend sending all data flows in the first port queue, and N is a positive integer; and the first network node suspends the first port queue from sending the first PFC frame to the second network node. The method helps better meet a service requirement of a data flow sent by a source node.

    摘要： This application discloses a network congestion control method and apparatus. A network congestion control solution is a congestion control solution based on hardware matching. When an intelligent network interface card obtains to-be-transmitted traffic, the intelligent network interface card may identify an algorithm matching feature of the traffic, and match a congestion control algorithm based on the algorithm matching feature of the traffic. Different algorithm matching features may match different congestion control algorithms. Therefore, a hardware-based network congestion control algorithm may be flexibly used.

    摘要： This application provides a network congestion processing method and a related apparatus. The method includes: performing ECN marking on a packet by using first ECN configuration information, and obtaining first network status information, where the first network status information is used to indicate a network status when the first ECN configuration information is used; determining second ECN configuration information based on the first ECN configuration information and the first network status information; and performing ECN marking on the packet by using the second ECN configuration information. In the foregoing technical solution, ECN configuration information to be subsequently used can be determined based on a network status of currently used ECN configuration information. In this way, ECN configuration information can be dynamically adjusted to adapt to a change in a network operating environment, thereby improving network performance.

    摘要： This application provides a packet control method and a network device. The method includes: detecting a packet flow causing a congestion status change; generating a congestion isolation message, where the congestion isolation message is used to change a priority of a packet in the packet flow, and the congestion isolation message includes description information of the packet flow; and sending the congestion isolation message to at least one node. According to the method, the network device, and the like provided in this application, when a congestion status changes, a packet flow that causes the congestion status change may be identified, and another node may be instructed to change a priority of a packet in the packet flow without affecting transmission of another packet flow. Therefore, a packet loss caused by congestion can be avoided, and head of line blocking caused by no congestion isolation can be avoided to a large extent, avoiding congestion diffusion.

    摘要： This application discloses a pool element PE status information synchronization method, including: receiving, by a pool register PR, a first registration message sent by a first PE, where the first registration message is used to add the first PE to a pool, and the first registration message carries an identifier of the first PE; receiving, by the PR, a second registration message sent by a second PE, where the second registration message is used to add the second PE to the pool, and the second registration message carries an identifier of the second PE; determining, by the PR, a role of the first PE in the pool according to the identifier of the first PE and the identifier of the second PE, where the role is an active PE or a standby PE; and sending, by the PR, a status synchronization manner, the identifier of the first PE, and information about the role of the first PE to the second PE. Therefore, costs are greatly reduced and a large-scale deployment of network functions virtualization can be better achieved.

    摘要： The present invention is applicable to the field of communications, and provides a method for automatically discovering a DLNA device, and a DLNA device, where the method includes: encapsulating, when a DLNA automatic discovery packet sent by a physical DLNA device is intercepted in a transparent manner, a protocol packet header in the DLNA automatic discovery packet, where the protocol packet header includes a home network identity; and sending the DLNA automatic discovery packet in which the protocol packet header is encapsulated to a Cloud DLNA device, so that the Cloud DLNA device sends the DLNA automatic discovery packet to a virtual DLNA device corresponding to the home network identity after removing the protocol packet header from the DLNA automatic discovery packet, and therefore the virtual DLNA device discovers, by using the DLNA automatic discovery packet, the physical DLNA device corresponding to the home network identity. The technical solutions provided in the present invention have an advantage of automatically discovering a DLNA device.
