Problems solved by technology

[0004] However, adopting the method for detecting whether the detection node in the prior art is reachable requires the network center node to send an icmp echo request message to each detection node and receive the icmp echo response message returned by each detection node, which is extremely Large consumption of network traffic

Abstract

The invention discloses a node detection method and a device and a network central node of network. The method comprises the following steps: acquiring a merge detection path from a pre-generated path merge list, wherein the path merge list includes the merge detection path; sending a first echo request message to a first detection node in the merge detection path, wherein the first echo request message includes a source routing option and a first destination IP address, the first destination IP address is the IP address of the first detection node in the merge detection path, and the source routing option includes IP addresses of detection nodes except the first detection node in the merge detection path; and determining the accessibility of the detection node in the merge detection path if a first echo response message returned by the last detection node in the merge detection path is received. The technical scheme of the embodiment of the invention greatly reduces the network flow.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a node detection method, device and network central node. Background technique [0002] At present, with the increasing number of nodes in the network, the scale of the network is getting larger and the complexity is getting higher and higher, which leads to higher and higher requirements for the reliability of the network. Therefore, detecting whether a node is reachable has become an important means to ensure network stability and troubleshoot network faults. If a node fails, that is, the node is unreachable, the node cannot process the received IP packets, and the IP packets received by the node will be discarded. At this time, if it is possible to detect whether the node is reachable in advance before deciding whether to send the IP packet to the node, the reliability of the network can be effectively improved. Therefore, detecting whe...
