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:
The present invention relates to a kind of method that fast detecting home router IP tunnel is communicated with.
Background technology:

In network application, application layer software can not judge network failure in time, occurs traffic failure or management interrupt.If the ceaselessly IP tunnel of detection network, will waste a lot of Internet resources again, and even cause server congestion, work abnormal.
Such as VOIP software, if do not check IP tunnel in time, it is also obstructed that user makes a call a few minutes, will give the impression of the no good cake of user.When multiple stage terminal, if connect voice server every now and then, will network congestion be caused, affect the quality of voice service.
The such as network management software, if do not check that network connects in time, network interruption, or topology changes, and just cannot report problem by Timeliness coverage.If detection network server always, also will cause congested.
Summary of the invention:
The object of this invention is to provide a kind of can whether connection the IP tunnel of detection network in time, and the method that the fast detecting home router IP tunnel that can reduce network load is communicated with.
Above-mentioned object is realized by following technical scheme:
The method that fast detecting home router IP tunnel is communicated with, this method comprises five steps, and first step terminal WAN port obtains IP address, starts network detection; Second step initiated ARP detection every 10 seconds to gateway, detects and successfully continue to wait for detection next time in 5 seconds; 3rd step 5 seconds does not obtain arp response later, just initiates DHCP and re-rents IP bag, judge whether Dynamic Host Configuration Protocol server is connected further; 4th step at the appointed time in receive response, continue to return the process of ARP detection, wait for ARP detection next time; 5th step at the appointed time in do not receive the response of DHCP Request, or DHCP Request exceedes predetermined number of times, removes the IP address that terminal obtains, restarts dhcp process.
The method that described fast detecting home router IP tunnel is communicated with, the 3rd described step is that transmission 3 DHCP Request re-rent IP bag.
The method that described fast detecting home router IP tunnel is communicated with, the DHCP request of the 5th described step exceedes predetermined number of times, restarts dhcp process, and the IP address of network reconfigures, the server resets of application layer software.
Whether the method that described fast detecting home router IP tunnel is communicated with, first use ARP detecting terminal to connect to the IP tunnel of gateway, secondly detect on failed basis at ARP, send DHCP request bag and regain IP address; Both obstructed basis judging, terminal disconnects to the IP tunnel of server; Go wrong the network ip address information that upgrades in time, and application layer software reports an error in time.
Beneficial effect:
1. the present invention adopts a kind of method of compromise to judge the situation of IP tunnel, and restarts network service, re-establishes network and connects.
2. client of the present invention is all concentrate on local local area network (LAN) or Intranet, and backbone network is generally unobstructed, so only need to judge that terminal is just passable to the connectedness of gateway, succinct, quick.
3. terminal equipment of the present invention only needs to initiate once to detect the ARP of gateway every 10 seconds, just can judge whether terminal is connected to gateway.
4., for major applications software, within 10 seconds, can detect that network failure just can meet the needs of user.The ARP request that terminal equipment of the present invention sends did not meet with a response in 5 seconds, and the DHCP request with regard to sending broadcast re-rents IP bag.
5. the present invention detects connectedness between terminal and gateway, and network distance is short, and in 5 seconds, not response, just can start DHCP request, judge whether network breaks down further.
6. the present invention is by the connectedness of 2 kinds of mode detection networks, guarantees to report network by mistake.
Accompanying drawing illustrates:
Accompanying drawing 1 is flow chart of the present invention.
Embodiment:
Embodiment 1:
The method that fast detecting home router IP tunnel is communicated with, this method comprises five steps, and first step terminal WAN port obtains IP address, starts network detection; Second step initiated ARP detection every 10 seconds to gateway, detects and successfully continue to wait for detection next time in 5 seconds; 3rd step 5 seconds does not obtain arp response later, just initiates DHCP and re-rents IP bag, judge whether Dynamic Host Configuration Protocol server is connected further; 4th step at the appointed time interior (3 DHCP Request wrap) receives response, continues the process returning ARP detection, waits for ARP detection next time; 5th step at the appointed time in do not receive the response of DHCP Request, or DHCP Request exceedes predetermined number of times, removes the IP address that terminal obtains, restarts dhcp process.
Embodiment 2:
The method that fast detecting home router IP tunnel described in embodiment 1 is communicated with, the 3rd described step is that transmission 3 DHCP Request re-rent IP bag.
Embodiment 3:
The method that fast detecting home router IP tunnel described in embodiment 1 is communicated with, the DHCP request of the 5th described step exceedes predetermined number of times, restarts dhcp process, and the IP address of network reconfigures, the server resets of application layer software.
Embodiment 4:
Whether the method that the fast detecting home router IP tunnel described in embodiment 1 is communicated with, first use ARP detecting terminal to connect to the IP tunnel of gateway, secondly detect on failed basis at ARP, send DHCP request bag and regain IP address; Both obstructed basis judging, terminal disconnects to the IP tunnel of server; Go wrong the network ip address information that upgrades in time, and application layer software reports an error in time.
Embodiment 5:
The method that fast detecting home router IP tunnel described in above-described embodiment is communicated with, first the WAN port of terminal obtains IP address, and starts network detection; Use DHCP again to refresh the mechanism of IP address, WAN port must be dynamic DHCP pattern; Terminal obtains IP address just can start application layer software later, starts the detection of IP tunnel.
