Embodiment Construction

[0056] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, but not to limit the present invention.

[0057] figure 1 is a flowchart of a method for detecting a data link provided by an embodiment of the present invention, such as figure 1 shown, including:

[0058] Step S101: the source node sends a data link detection request message to the destination node;

[0059] Step S102: the source node receives a data link detection response message corresponding to the data link detection request message;

[0060] Step S103: the source node obtains the source IP address in the data link detection response packet, and determines whether the data link between the source node and the destination node is interrupted according to the source IP address.

[0061] The determining ...

Abstract

The invention discloses a data link detection method, device and system, and relates to the technical field of network communication. The method includes: a source node sends a data link detection request message to a destination node; the source node receives the data link The data link detection response message corresponding to the road detection request message; the source node obtains the source IP address in the data link detection response message, and determines the source node to the Whether the data link between the destination nodes is interrupted.

Description

technical field [0001] The present invention relates to the technical field of network communication, and in particular, to a data link detection method, device and system. Background technique [0002] IPv4 (Internet Protocol version 4, Internet Protocol version 4) is a network layer protocol currently used by the Internet. So far, IPv4 is running well and stably. However, with the rapid development of the Internet and the services provided on it, IPv4 has exposed some deficiencies. IPv6 (Internet Protocol version 6, Internet Protocol version 6) is the second-generation standard protocol of the network layer protocol, also known as IPng (IP next generation, next generation Internet), it is the IETF (Internet Engineering Task Force, Internet Engineering Task Force) Group) designed a set of specifications, is an upgraded version of IPv4. IPv6 has many new features and solves many shortcomings of IPv4, so it gradually attracts more and more people's attention and becomes a n...
