Description
Technical Field
The invention relates to the technical field of network telemetry, in particular to a data acquisition system and a data acquisition method.
Background
In recent years, the rapid development of network technology has brought about great challenges to network management and operation and maintenance. Conventional network probing techniques such as ping and traceroute methods are not very accurate in locating forwarding paths and network delays. In-band network telemetry (INT) has emerged accordingly. The in-band network telemetry is a hybrid measurement technique, which is a technique for collecting, carrying, sorting and reporting telemetry data (network equipment information) by means of data plane service, and network equipment information is collected without using a separate control plane to manage traffic. The in-band is to say that the information of the network device to be collected is carried in the existing message of the data plane, and a specific message does not need to be actively generated to detect. Data acquisition of the data plane requires programmable technology based on a switch chip.
The technical standards of the current telemetry technology mainly comprise: standards for the data plane and standards for telemetry reporting. The IETF and P4 organizations both currently propose standards for the relevant data plane. The IETF sets forth the Inband Flow Analyzer (IFA) standard, and P4 sets forth the In-band Network Telemetry (INT) standard. For a switch, the implementation of both technologies places requirements on the programmable modules of the switch chip of the switch. When the data plane carries out telemetering data acquisition, the operations of editing, modifying, calculating and the like are required to be carried out on the message through the programmable module, and then the telemetering data can be inserted into the message. Therefore, the number of operation instructions and the length of data that can be provided by the programmable module of the switch chip limit the implementation of the two standards in practical applications. In order to deal with the limitation of the foreign advanced chip technology country on the high salary technology development of China, the development of the autonomous exchange chip starts to rise.
At present, domestic independent exchange chip research and development manufacturers mainly comprise Huacheng, shengke, murphy microelectronics and the like. Part of products can support end-to-end data analysis in an INT standard protocol, and part of products are limited by factors such as chip instruction quantity and the like, can only support single-hop data acquisition and uploading, and no product can simultaneously realize end-to-end data analysis under the conditions of single-hop data acquisition and uploading.
Based on this, the present application proposes a data acquisition system and method to solve the above problems.
