Embodiment 1

[0021] A method for quickly detecting the connectivity of the IP channel of a home router. This method includes five steps. The first step is to obtain the IP address of the terminal WAN port and start network detection; Successfully continue to wait for the next detection; the third step does not get an ARP response after 5 seconds, and then initiates a DHCP lease renewal IP packet to further determine whether the DHCP server is connected; the fourth step receives within the specified time (3 DHCP Request packets) Response, continue to return to the ARP detection process, and wait for the next ARP detection; the fifth step does not receive a DHCP Request response within the specified time, or the DHCP Request exceeds the specified number of times, clear the IP address obtained by the terminal, and restart the DHCP process.

Embodiment 2

[0023] In the method for quickly detecting the connectivity of the IP channel of the home router described in Embodiment 1, the third step is to send 3 DHCP Request IP packets for lease renewal.

Embodiment 3

[0025] In the method for quickly detecting the connectivity of the IP channel of the home router described in embodiment 1, the DHCP request in the fifth step exceeds the specified number of times, the DHCP process is restarted, the IP address of the network is reconfigured, and the service of the application layer software is restarted.

Abstract

The invention provides a method for quickly detecting communication of an IP channel of a household router. The method is characterized by comprising the following five steps: 1, acquiring IP address through a WAN port of a terminal, and starting network detecting; 2, sending ARP (Address Resolution Protocol) detection to a gateway at every 10 seconds, and continuously waiting for the next detection after successfully detecting within 5 seconds; 3, sending DHCP (Dynamic host configuration protocol) to relet an IP packet if the ARP response is not received after 5 seconds, and further determining whether a DHCP server is connected; 4, continuously returning to the ARP detection if the response is received within the specified time, and waiting for the next ARP detection; 5, clearing the IP address obtained by the terminal and starting a new DHCP process is the DHCP Request response is not received within the specified time or the DHCP Request exceeds the specified time. The method is used for detecting whether the IP channel of the household router is communicated.

Description

Technical field: [0001] The invention relates to a method for quickly detecting the connection of the IP channel of the home router. Background technique: [0002] In practical applications, the application software on the network equipment cannot perceive the smoothness of the IP channel, and there will be service or management interruptions, such as VOIP software and network equipment management software. If there is no method for quickly detecting the connectivity of the IP channel, it will take a long time for these application software to judge the network failure, which makes the user feel that the performance of the software is very poor. If it can be judged in time that there is a problem with the IP channel, the application software will be able to restart the network service, or remind the user to report and repair in time. The usual method is to continuously connect to the server to determine whether the network service is normal. [0003] In network application...
