Description
Technical field
The present invention relates to the communications field, espespecially a kind of method and system of test router forwarding multicasting DNS message.
Background technique
Multicast DNS refers to multicast DNS (Multicast DNS), mainly realizes in not legacy DNS server
In the case of, the host in local area network realizes mutually discovery and communication.The use of multicast DNS, allow client do not need through
It crosses traditional dns server and inquires the IP address of given host name, and well solved and named in zero configuration network
Problem.Each host into local area network all can All hosts into local area network if opening multicast DNS service
One message of multicast, Who Am I (domain name) and my IP address is how many.Then other have the host of multicast DNS service will
Response, can also tell you, whose (domain name) it is, its IP address is how many.It is exactly to use multicast when certain equipment needs to service
The corresponding IP address of DNS query domain name, corresponding equipment equally pass through multicast mode response after receiving the message, other are led at this time
Machine equipment is also that can receive the response message, other hosts also will record domain name and IP, updates caching.
Current multicast DNS message is widely used in the shared scene of home network, for example the audio sync in local area network is broadcast
It puts, video is launched, projection and printing function etc..But the net as used in the terminal of the distinct interface connection on router
Network is different, such as the connection local area network having, some connection guest networks, and the connecting wan having.And home network is shared
In order to avoid privacy leakage and resource are occupied when router forwarding multicasting DNS message, usually only allow to turn in local area network
Hair, and in order to guarantee that the host in local area network net with multicast DNS service can be found in time, it is therefore desirable to test routing
Whether the function of device forwarding multicasting DNS message is normal.
Summary of the invention
The object of the present invention is to provide a kind of method and system of test router forwarding multicasting DNS message, realize test
The function of each interface crawl multicast DNS message of router, it is ensured that isolation local area network and visitor's net when sending multicast DNS message
Network, local area network.
Technical solution provided by the invention is as follows:
The present invention provides a kind of method of test router forwarding multicasting DNS message characterized by comprising several

Include:
Remaining LAN testing terminal, guest network test terminal and wide area network test terminal grab multicast DNS message；
When LAN testing terminal grabs multicast DNS message, the interface for sending the connection of LAN testing terminal can be forwarded
The result of multicast DNS message is to router；Otherwise it sends and fails the result of forwarding multicasting DNS message to router；
When guest network test terminal does not grab multicast DNS message, the interface of transmission guest network test terminal connection
Fail the result of forwarding multicasting DNS message to router；Otherwise send can forwarding multicasting DNS message result to router；
When wide area network test terminal does not grab multicast DNS message, the interface for sending wide area network test terminal connection fails
The result of forwarding multicasting DNS message is to router；Otherwise send can forwarding multicasting DNS message result to router.
Specifically, in the present embodiment, any test terminal hair in main several LAN testing terminals of test terminal control
Send multicast DNS message to router, router forwarding multicasting DNS message to remaining LAN testing terminal, guest network test
Terminal and wide area network test terminal.Wherein main test terminal is LAN testing terminal or guest network test terminal or wide area network
Any one in terminal is tested, and if main test terminal is LAN testing terminal, sends multicast DNS message
Test terminal can be main test terminal, be also possible to remaining LAN testing terminal of non-master test terminal.Remaining local
Net tests terminal, guest network test terminal and wide area network test terminal and grabs multicast DNS message, and will grab result (can
Grab or grab less than) be sent to router.
LAN testing terminal sends multicast DNS message in the application, tests remaining LAN testing terminal, guest network
Whether terminal and wide area network termination can grab, and determine the multicast DNS report sent in local area network when router feature is normal
Text only has terminal in local area network that can grab, guest network terminal and wide area network termination all grab less than.To local area network
Interior terminal can and be merely able to avoid private data leakage to visitor's net to be all that remaining terminal of local area network provides service
Network terminal and wide area network termination, and avoid router from E-Packeting and occupy Internet resources to excessive terminal.
Fourth embodiment of the invention is the optimal enforcement example of above-mentioned second embodiment, as shown in figure 4, the present embodiment with it is upper
It states second embodiment to compare, main improve is:
Several any test terminals of main test terminal control send multicast DNS message to router；Router forwarding group
DNS message to the other several test terminals connecting with router are broadcast to specifically include:
Several guest networks of main test terminal control test any test terminal in terminal and send multicast DNS message to road
By device；
Router forwarding multicasting DNS message to LAN testing terminal, remaining guest network test terminal and wide area network is surveyed
Try terminal；
Several test terminals grab multicast DNS message, and the crawl result of multicast DNS message is fed back to routing implement body
Include:
LAN testing terminal, remaining guest network test terminal and wide area network test terminal grab multicast DNS message；
When LAN testing terminal does not grab multicast DNS message, the interface for sending the connection of LAN testing terminal fails
The result of forwarding multicasting DNS message is to router；Otherwise send can forwarding multicasting DNS message result to router；
When guest network test terminal does not grab multicast DNS message, the interface of transmission guest network test terminal connection
Fail the result of forwarding multicasting DNS message to router；Otherwise send can forwarding multicasting DNS message result to router；
When wide area network test terminal does not grab multicast DNS message, the interface for sending wide area network test terminal connection fails
The result of forwarding multicasting DNS message is to router；Otherwise send can forwarding multicasting DNS message result to router.
Specifically, several guest networks of main test terminal control test any test terminal in terminal in the present embodiment
Multicast DNS message is sent to router, router forwarding multicasting DNS message to LAN testing terminal, remaining guest network are surveyed
It tries terminal and wide area network tests terminal.Wherein main test terminal is LAN testing terminal or guest network test terminal or wide area
Net tests any one in terminal, and if main test terminal is guest network test terminal, sends multicast DNS report
The test terminal of text can be main test terminal, be also possible to remaining guest network test terminal of non-master test terminal.Office
Domain net test terminal, remaining guest network test terminal and wide area network test terminal grab multicast DNS message, and will grab result
(can grab or grab less than) is sent to router.
Guest network test terminal sends multicast DNS message in the application, tests LAN testing terminal, remaining visitor's net
Whether network terminal and wide area network termination can grab, and determine the multicast that guest network terminal is sent when router feature is normal
Terminal, guest network terminal and wide area network termination are all grabbed less than to avoid guest network terminal in DNS message local area network
Occupy the Service Source that terminal provides in local area network.
Fifth embodiment of the invention is the optimal enforcement example of above-mentioned second embodiment, as shown in figure 5, the present embodiment with it is upper
It states second embodiment to compare, main improve is:
