Abstract

The invention discloses a port state recognition method, device and system. The port state recognition method includes acquiring a TCP-SYN data package constructed in advance, wherein the TCP-SYN data package comprises a first MAC address and a service port parameter, the first MAC address is the MAC address of a recognized server, and the service port parameter of the parameter that a service port of the recognized server corresponds to; transmitting the TCP-SYN data package to a server that the first MAC address corresponds to, wherein the server that the first MAC address corresponds to returns a response package after receiving the TCP-SYN data package, and the response package comprises information used for reflecting the state of the service port that the service port parameter corresponds to; receiving the response package returned by the server that the first MAC address corresponds to; analyzing the returned response package to obtain the state of the service port that the service port parameter corresponds to. The method, device and system solves the problem that the application service recognition efficiency is low and achieves the effect of improving the application service recognition efficiency.

Description

technical field [0001] The present invention relates to the field of application service scanning, in particular to a port state identification method, device and system. Background technique [0002] Application service identification is one of the basic functions of network management and security management systems. The perfect application service identification and scanning function can provide rich technical support for the upper layer functions of the management system. And it has a wide range of applications, such as: identification of host system services, Web services, database services, and middleware services can be based on the scanning function. In addition, future virtualization services, big data storage network services, etc. can also achieve elastic expansion based on this scanning function. [0003] In general, the vendor development teams of each management system will choose to implement the application service identification function based on the Telne...
