[0044] The iFIT technology for measuring along-flow information can use a special iFIT header to perform characteristic marking on data packets flowing through network nodes, and the characteristic marking can also be called coloring. The iFIT header may be used, for example, as an extension header of a multi-prot...

Abstract

The invention discloses an in-situ flow information telemetry (iFIT) capability confirming method and device. The method comprises the steps that a first network device sends a request message to a second network device or a network management device, wherein the request message is used for requesting to confirm whether the second network device has the iFIT capability; and the first network device receives a confirmation message sent by the second network device or network management equipment, wherein the confirmation message comprises confirmation information for confirming whether the iFIT capability exists or not. The method can ensure that the data message including the iFIT information is sent to the second network device only when the second network device has the iFIT capability, so the problem of packet loss caused by the fact that the network equipment does not have the iFIT capability is solved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for confirming the iFIT capability of a network device in an in-situ FlowInformation Telemetry (iFIT) business scenario. Background technique [0002] By marking actual service traffic and based on the fields of the feature mark, iFIT technology can provide end-to-end and hop-by-hop telemetry capabilities of real service traffic, and perceive network performance indicators in real time. The iFIT technology described here refers to the personal draft of "In-situ Flow Information Telemetry Framework (English: In-situ Flow Information Telemetry Framework)" submitted by the Internet Engineering Task Force (English: The Internet Engineering Task Force, IETF). Links can be found at https: / / tools.ietf.org / html / draft-song-opsawg- ifit-framework-00 . The network based on iFIT technology includes three types of network nodes, specifically head...
