The present invention provides a method and device for transmitting a control message. The method includes a forwarding device obtaining a control message, the control message carrying information corresponding to a hash tuple of the forwarding device, and the information of the hash tuple Including hash algorithm information, forwarding encapsulation type information and hash parameter information, the hash algorithm information indicates the hash algorithm used by the forwarding device to forward the first data packet, and the forwarding encapsulation type information indicates that the forwarding device forwards the first data packet The encapsulation type used by the data message, the hash parameter information represents the hash parameter used by the forwarding device to forward the first data message; the forwarding device sends the control message to the network device used to monitor the forwarding device, so that the network The network device used to monitor the forwarding device can obtain the information of the hash tuple corresponding to the forwarding device through the control packet.
Description
technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and device for transmitting control messages. Background technique [0002] The process of load sharing when a traditional forwarding device forwards a data message is specifically to classify the data message according to the characteristics of the data message. Determine a certain value domain space, and map a specific value in this certain space to a specific route and egress. [0003] For example, in the backbone network of a Border Gateway Protocol (Border Gateway Protocol, BGP) or Multi-Protocol Label Switching (Multi-Protocol Label Switching, MPLS) virtual private network (Virtual Private Network, VPN) scenario, data packets are usually passed through the label The label switching path (Label Switched Path, LSP) of the distribution protocol (Label Distribution Protocol, LDP) or the resource reservation protocol (Resource ReServation Protocol-Traffic...
