Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
Fig. 1 is a schematic diagram of a system implementing network telemetry according to some embodiments of the present disclosure.
As shown in fig. 1, the system 100 of this embodiment includes: a Radius (remote authentication Dial Inuser Service) server 110 and several network devices 120.
The Radius server 110 is used to issue network telemetry policies and collect probe data.
A probe is deployed on network device 120 and may be used to probe data according to a network telemetry policy.
The Radius server 110 and the network device 120 perform information interaction through a Radius protocol, such as issuing a network telemetry policy, reporting detection data, and the like.
Since the Radius Protocol is implemented based on UDP (User Datagram Protocol), the efficiency of data acquisition can be improved by network telemetry implemented based on Radius.
Fig. 2 is a schematic diagram of a method of implementing network telemetry according to some embodiments of the present disclosure.
As shown in fig. 2, the method of this embodiment includes:
step 210, the Radius server sends a Radius telemetry policy message to the network device, where the Radius telemetry policy message carries the network telemetry policy.
The Radius Telemetry strategy message (referred to as telemetric-Radius-Policy) is newly defined in the disclosure and is a Radius message carrying a network Telemetry strategy.
In some embodiments, the network telemetry policy includes information such as user data acquisition requirements (e.g., delay, jitter, etc.) and transmission time intervals of probe results.
In some embodiments, the network telemetry policy is user set.
And step 220, the network equipment receives the Radius telemetry strategy message sent by the Radius server and performs data detection according to the network telemetry strategy.
The data detection is performed according to the data acquisition requirement information of the user in the network telemetry strategy, and the data detection content includes, for example: user per queue data processing, user message processing latency, or traffic jitter, but are not limited to the examples given.
Step 230, the network device returns a Radius charging message to the Radius server, where the Radius charging message carries the detection result.
The Radius charging message (set as Radius-accounting) is a newly defined Radius charging message of the present disclosure, and carries a newly defined Radius telemetry Attribute field (set as elementary-Radius-Attribute). And the network equipment writes the detection result into a Radius telemetering attribute field of the Radius accounting message.
And returning a Radius charging message to the Radius server according to the sending time interval of the detection result in the network telemetry strategy.
And step 240, the Radius server receives the Radius charging message returned by the network device, and extracts the detection result from the Radius charging message.
In some embodiments, the Radius server extracts the probe result from the Radius telemetry attribute field of the Radius accounting packet.
Compared with the network telemetry realized based on TCP, the network telemetry realized based on Radius (UDP) can improve the efficiency of data acquisition. In addition, because the method is realized based on the Radius attribute extension, the network equipment does not need to be upgraded to support other protocols such as gRTC, and therefore, the method is easier to popularize.

When the user dial-up is authenticated, the Radius server sends Telemetry-Radius-Policy information to the gateway, wherein the Telemetry Policy of the user is carried.
Then, based on the strategy, the gateway enables refined data statistics, such as information of data processing conditions of each queue of the user, user message processing delay, flow jitter and the like, for the user, and writes the statistical information into a Telemetry-Radius-Attribute field.
And then, at a time interval specified by the strategy, the gateway equipment transmits the collected specific information to the Radius server through a telemetering-Radius-Attribute field of the Radius accounting message.
