Overlay network-oriented lightweight in-band network telemetering method and device and storage medium

Abstract

The invention discloses an overlay network-oriented lightweight in-band network telemetering method and the method comprises the following steps: S1, packaging an IP message, so as to obtain a detection data packet so that the detection data packet sequentially collects the ID of underlay equipment along the way and the link state information of an equipment port side; S2, analyzing the detection data packet; S3, starting to traverse by taking any equipment in the Overlay network as a root node to obtain a non-overlapping detection path; S4, performing control according to the detection path in the step S3 to obtain a customized detection data packet forwarding path; and S5, after the detection data packet reaches the end point, storing and querying the acquired network monitoring information. The invention also provides an overlay network-oriented lightweight in-band network telemetering device and a storage medium, and lightweight Overlay network monitoring can be realized with lower overhead.

Description

technical field [0001] The invention belongs to the communication field, and more specifically relates to a lightweight in-band network telemetry method, device and storage medium for an Overlay network. Background technique [0002] With the widespread application of cloud computing in data centers and enterprise networks, the cloud service model has become an important service model. As a prominent feature of cloud computing, virtualization technology can effectively improve resource utilization and reduce data center operation and maintenance costs. However, problems caused by the increase in the number of virtual machines and frequent dynamic migration of virtual machines have also emerged. The traditional network can no longer meet the needs of virtual machines without awareness of migration between arbitrary network locations. Therefore, the Overlay network solution should be used And born. [0003] In the field of network technology, Overlay refers to a virtualizati...
