Embodiment Construction

[0047] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0048] 1) Automatic collection of service access behavior characteristics

[0049] a) The underlying driver interface of the network device

[0050] Use the Winpcap free network underlying driver and the corresponding development library files to obtain the network packet data packets passing through the specified network equipment. In the Java language environment, you can use the Jpcap class library to obtain the underlying network packet, and you can obtain the source IP address, destination IP address, sequence number, confirmation number, urgent data flag, and confirmation number valid flag contained in the TCP packet. , Send mandatory function flags, request connection reset flags, sequence number confirmation flags, send end flags, window size, urgent data pointers and data and other information.

Abstract

An HTTP protocol-based automatic monitoring method for electronic resource service availability includes three stages: automatic collection of service access behavior characteristics; service access behavior characteristic storage; service access behavior simulation and discrimination. The invention can be used to monitor the running state of the network service that provides electronic resource retrieval and download services through the HTTP protocol, and the application includes the monitoring of purchased document database services by colleges and universities and scientific research institutes. The present invention completes the monitoring information collection and monitoring implementation for the availability of the electronic resource service based on the HTTP protocol without manually analyzing the code of the electronic resource service web page and without obtaining the control authority of the electronic resource server. Users who use the monitoring function do not need to do any manual analysis on the search page code, and can automatically complete the collection of all information on the search Form and the real network address of the downloaded file, which has a very high level of automation.

Description

technical field [0001] The invention relates to an automatic monitoring method for the availability of electronic resource services based on the HTTP protocol, which is used for monitoring the running status of network services providing electronic resource retrieval and download services through the HTTP protocol. Background technique [0002] At present, Web technology has penetrated into the daily life of human beings. There are already a large number of network services that provide electronic resource retrieval and download services through the HTTP protocol. Typical representatives are various document database resource platforms, such as ACM, SCI-E, and Springer Link. Wait. For the needs of teaching and research, many institutions of higher learning and scientific research institutions will purchase a large number of literature databases. However, affected by the instability of the network environment and the availability of network services, domestic colleges and sc...
