This application discloses a method, device, and system for controlling packet sending, to control sending of a link state advertisement packet. The method includes: obtaining a first quantity of link state advertisement packets sent by a transmitting end device to a receiving end device in a first time period, obtaining a second quantity of link state advertisement packets received by the receiving end device from the transmitting end device in a second time period, adjusting a link state advertisement packet receive window value of the receiving end device based on the first quantity and the second quantity, and sending an adjusted link state advertisement packet receive window value to the transmitting end device.

Method, network device, and system for controlling packet sending

This application provides a method for updating a route in a network. The first network device sends a first LSA packet to a third network device, so that the third network device generates a first route whose destination address is a second IP address, where a next-hop IP address of the first route is the IP address of the first network device, and the second IP address belongs to the IP network segment corresponding to the first IP address which is an IP address of the first network device. The first network device sends a second LSA packet to the third network device when determining that switching needs to be performed on a next hop of a route in the third network device, whose destination address belongs to the IP network segment, and whose next-hop IP address is the first IP address.

Method for updating route in network, network device, and system

Embodiments provide a packet processing method. In accordance with this method, a first LSP packet can be received by a network device. The following determinations can be made: that the network device stores no LSP packet whose LSP ID and PDU type are the same as an LSP ID and PDU type of the first LSP packet; that the network device has stored a second LSP packet whose LSP ID is the same as an LSP ID of the first LSP packet and PDU type is the same as a PDU type of the first LSP packet, and that a sequence number of the second LSP packet is less than a sequence number of the first LSP packet. When one or more of these determination are made, a determination whether LSP packet digest information matching the first LSP packet exists can be made. When the LSP packet digest information matching the first LSP packet is determined to exist, the first LSP packet can be stored.
