Lightweight in-band network telemetry method, device and storage medium for overlay network

Abstract

The invention discloses a lightweight in-band network telemetry method oriented to an Overlay network, comprising the following steps: S1. Encapsulating IP packets to obtain detection data packets, so that the detection data packets can sequentially collect IDs of Underlay devices along the way and Link state information on the port side of the device; S2, analyze the detection data packet; S3, start traversing with any device in the overlay network as the root node, and obtain a non-overlapping detection path; S4, according to the detection path in step S3 Perform control to obtain a customized forwarding path of the detection data packet; S5, when the detection data packet reaches the end point, store and query the collected network monitoring information. The present invention also provides a lightweight in-band network telemetry device and a storage medium oriented to the overlay network of the present invention, which can realize the lightweight overlay network monitoring with lower overhead.

Description

technical field [0001] The invention belongs to the field of communications, and more particularly, relates to a lightweight in-band network telemetry method, device and storage medium oriented to 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 significant feature of cloud computing, virtualization technology can effectively improve resource utilization and reduce data center operation and maintenance costs. However, the problems caused by the increase in the number of virtual machines and the frequent dynamic migration of virtual machines also appear. Traditional networks can no longer meet the needs of non-aware migration of virtual machines between any network location. Therefore, the overlay network solution should be used as the times require. and live. [0003] In the field of network technology, overlay ref...

Problems solved by technology

[0012] Aiming at the problem that the Overlay network monitoring system constructed by the INT technology existing in the prior art cannot realize the monitoring and management of data center network traffic, effective planning of detection paths, and acquisition of monitoring information of network link devices at a lower cost, the present invention A lightweight in-band network telemetry method, device and storage medium for Overlay network is proposed, which realizes the accurate collection and monitoring of equipment status information in the Overlay network link; further, this method combines path planning in the Overlay network strategy, using fewer paths to cover the entire network for telemetry, combined with the proposed "two-way detection" and "two-step search" strategies, while realizing effective monitoring of the Overlay network, the network monitoring overhead is reduced; in addition, the lightweight The magnitude network monitoring method helps to get rid of the monitoring dilemma of the Overlay network and realize the low-overhead network monitoring function
