Abstract

The invention discloses a method and a device for generating a network topology based on sFlow, and relates to the technical field of computers. The method comprises the following steps of determiningflow data with the same quintuple in sFlow flow data as a set, and storing the set in a network flow hash table; acquiring network node data of the network flow, and determining a source IP address of the network flow as a starting point of a topological structure; when a first node in a TTL value sequence is a first-level node, determining the first node as the first-level node of the topological structure; or when a plurality of first nodes are not the first-level node, matching a next-hop IP address of the source IP address with the IP addresses of the first nodes, and taking the first nodes as the first-level nodes of the topological structure; and when the next-hop IP address of the first-level node is determined as a destination IP address of the network flow, determining the destination IP address as a next-level node of the first node.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular to a method and device for generating network topology based on sFlow. Background technique [0002] sFlow (RFC3176) is a network monitoring technology approved by IETF as a draft standard in 2001. It uses random sampling of LAN and WAN data packet flows transmitted on the entire network to allow users to grasp the network transmission in detail and in real time. Flow performance, trends, and issues. [0003] The sFlow system is mainly composed of an sFlow agent (Agent) implanted in a router or a switch and a central collector. The system collects raw data from the network by the router or switch, and then sends it to the Agent to encode data packets in a specific format and forward them. to the central collector. sFlow technology allows users to configure the sampling rate and polling time by themselves, and can collect complete packet header information, complete d...
