Embodiment 1

[0060] figure 1 A flow chart of a data center network telemetry method is shown, Figure 5 A schematic diagram of a working principle of a data center network telemetry method is shown. Such as figure 1 and Figure 5 As shown, this embodiment provides a data center network telemetry method, which is applied to a telemetry server, and includes the following steps:

[0061] Step S110, acquiring multiple telemetry queries.

[0062] Wherein, the telemetry query is obtained through a telemetry application input through a preset API (Application Programming Interface, application programming interface).

[0063] Network administrators can write telemetry applications, input the default API exposed by the telemetry server, and then obtain telemetry reports without directly manipulating the underlying network facilities. Telemetry applications can perform various telemetry queries through preset APIs, and express telemetry applications within the entire data center network on dem...

Embodiment 2

[0117] Figure 6 shows a block diagram of a data center network telemetry system, such as Figure 6 As shown, this embodiment provides a data center network telemetry system, including:

[0118] A telemetry service provider 610, configured to obtain multiple telemetry queries and distribute them to the telemetry coordinator;

[0119] A telemetry coordinator 620 for generating probes using a preset probe generation algorithm and a plurality of telemetry queries:

[0120] telemetry transceiver 630 for injecting probes into and collecting probes from the data center network;

[0121] The telemetry analyzer 640 is configured to analyze the collected probes, obtain a telemetry result corresponding to the telemetry query, and transmit the telemetry result to the telemetry service provider.

[0122] It can be understood that the telemetry service provider 610 can be used to perform step S110 in the first embodiment, the telemetry coordinator 620 can be used to perform the step S12...

Embodiment 3

[0125] This embodiment provides a storage medium, on which a computer program is stored. When the computer program is executed by one or more processors, the data center network telemetry method in the first embodiment is implemented.

[0126] In this embodiment, the storage medium can be realized by any type of volatile or non-volatile storage device or their combination, such as Static Random Access Memory (Static Random Access Memory, SRAM for short), Electrically Erasable and Programmable Electrically Erasable Programmable Read-Only Memory (EEPROM for short), Erasable Programmable Read-Only Memory (EPROM for short), Programmable Read-Only Memory (PROM for short) ), read-only memory (Read-Only Memory, ROM for short), magnetic memory, flash memory, magnetic disk or optical disk.

Abstract

The invention provides a data center network telemetering method, a data center network telemetering system, a storage medium and a telemetering server, which are used for carrying out on-demand telemetering on a data center network under the condition of meeting the requirements of full coverage and expandability. The data center network telemetering method comprises the following steps: acquiring a plurality of telemetering queries; generating a probe by using a preset probe generation algorithm and the plurality of telemetry queries; injecting each probe into the data center network, and collecting the probes from the data center network; and analyzing the collected probes to obtain a telemetry result corresponding to the telemetry query.

Description

technical field [0001] The invention relates to the technical field of network telemetry, in particular to a data center network telemetry method, system, storage medium and telemetry server. Background technique [0002] In traditional networks, due to issues such as complex design and hardware process limitations, it often takes several years to add new functions or new network protocols to switching chips, making it difficult for network equipment to meet the development requirements of rapid new protocols and network protocols. Aiming at the challenge of slow evolution of network equipment, the team led by Professor Nick McKeown of Stanford University proposed a protocol-independent programmable data plane architecture. Based on the reconfigurable matching action table, the architecture builds a protocol-independent data packet processing pipeline through programmable control logic, and can quickly add new network functions to the switching chip. Through the programmabl...
