Problems solved by technology

Since the commonly used ping does not record information with time stamps, it is impossible to rule out the network status in the past tense, making it impossible to perform troubleshooting and analysis at the network level.

Embodiment Construction

[0018] Such as figure 1 As shown, this embodiment is a network detection method with a time algorithm, including a monitoring host and terminal computers, servers, printers and other networked terminal devices located in the same local area network.

[0019] Such as figure 2 As shown, the network monitoring method of this embodiment includes the following steps:

[0020] The monitoring host sends ICMP data packets to the specified network terminal device IP every second;

[0021] For example, after the networked terminal device receives the ICMP data packet through the LAN, it will reply to the host, and use the ICMP data packet when replying;

[0022] If the monitoring host receives the ICMP data packet sent by the networked terminal device, it will record the received time point, data packet size and transmission time and other information; if the monitoring host sends the ICMP data packet to the specified networked terminal device IP within a certain period of time When...

Abstract

The invention relates to a network monitor method and system with a time algorithm. The method adopts a monitor host in the same local area network and a plurality of networked terminal equipment, wherein the monitor host sends an ICMP data packet to designated networked terminal equipment IP every T1, if the networked terminal equipment receives the ICMP data packet through the local area network, the networked terminal equipment uses the ICMP data packet to reply the monitor host; if the monitor host receives the ICMP data packet sent by the networked terminal equipment, the monitor host records receiving time point, data packet size and transmission time; if the monitor host fails to receive the ICMP data packet replied by the networked terminal equipment within T2 after sending the ICMP data packet to the designated networked terminal equipment IP, the monitor host records a time point at when a reply by the networked terminal equipment fails to receive; and recorded content is saved on a local memory or a log server. The network monitor method and system are applied to the field of network supervision.

Description

technical field [0001] The invention relates to a network monitoring method and system with time algorithm. Applicable to the field of network supervision. Background technique [0002] At present, the ping command is often used to detect the status of the network. However, the "request timeout" that occurs in this method does not have a clear timestamp to describe it. Due to the sporadic possibility of the network, when the system is temporarily inaccessible in the factory area, it is necessary to detect the network status when the failure occurs. Since the commonly used ping does not record information with a time stamp, the network status in the past tense cannot be ruled out, making it impossible to perform troubleshooting and analysis at the network level. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a network monitoring method and system with a time algorithm for the above existing problems. [0004] ...
