Based on the above-mentioned characteristic of view networking, one of the core concepts of the embodiments of the present invention is proposed, it then follows regard the association of networking
View sends different types of data packet to its own in a manner of transparent transmission from view networked terminals, is received by judgement view networked terminals
The case where different types of data packet arrived, determine whether the MAC Address depending on networked terminals supports multi-wad join.
Referring to Fig. 5, a kind of step flow chart of detection method embodiment of the invention is shown, this method can be applied to
Depending on networked terminals, it can specifically include following steps:
Step 501, the view networked terminals send the first data packet of preset quantity in a manner of transparent transmission to its own；It is described
Sub- device number in first data packet is the first numerical value.
It should be noted that the MAC Address depending on networked terminals can be set to support multi-wad join and not support multichannel to connect
Two types are connect, supports the MAC Address of multi-wad join corresponding and can establish multiple data link accesses depending on networked terminals.It is regarding
When networked terminals establish multiple data link accesses, an effective sub- equipment can be distributed to each data link access
Number；And depending on networked terminals without that can give and correspond to when establishing data link access or need to only establish a data wired link access
Access distribute an invalid sub- device number.Definition about effective sub- device number and invalid sub- device number can have more
Kind, for example, be greater than 0 and any value within the sub- device number usable range be effective sub- device number, 0 is invalid
Sub- device number, sub- device number usable range are the quantity for regarding the supported data link access of MAC Address of networked terminals, than
Such as, the quantity of supported data link access is 10, then the usable range of sub- device number can be 1~10.
Specifically, the first numerical value is set by the sub- device number in the corresponding transparent transmission parameter of the first data packet, first number
Value is an effective sub- device number, sends the first data of preset quantity to its own in a manner of transparent transmission depending on networked terminals
Packet, preset quantity are at least one.
It should be noted that it is not limited to transparent transmission mode to its own mode for sending data packet depending on networked terminals, it can also be with
It is sent by way of establishing data link access.Compared with the mode for establishing data link access, transparent transmission mode is operated more
Simplicity, therefore the Union of Central Vision of embodiment of the present invention network termination sends data packet to its own using transparent transmission mode.
Step 502, if described receive at least one described first data packet depending on networked terminals, it is determined that the view networking
The MAC Address of terminal supports multi-wad join.
Specifically, it if the MAC Address of view networked terminals supports multi-wad join, is transmitted in a manner of transparent transmission depending on networked terminals at this
When data, set an effective sub- device number for the sub- device number in transparent transmission parameter, then receiving end can depending on networked terminals
To receive the data of transmission；Otherwise, if the MAC Address depending on networked terminals does not support multi-wad join, the view networked terminals with
When transparent transmission mode transmits data, an effective sub- device number is set by the sub- device number in transparent transmission parameter, then receiving end
The data of transmission cannot be received depending on networked terminals.Based on this, the view networked terminals of multi-wad join are supported for MAC Address, it can
The first data packet of its own oriented transmission to receive, still, it is contemplated that the influence of the other factors such as transparent transmission service exception,
In the case where receiving at least one first data packet depending on networked terminals, that is, it can determine the MAC Address branch of the view networked terminals
Hold multi-wad join.
Optionally, after view networked terminals send the first data packet of preset quantity to its own, if the view is networked
Terminal does not receive first data packet, then the view networked terminals send the of preset quantity to its own in a manner of transparent transmission
Two data packets, the sub- device number in second data packet are second value；If described receive at least one depending on networked terminals
Second data packet, it is determined that the MAC Address depending on networked terminals does not support multi-wad join.
After view networked terminals send the first data packet of preset quantity to its own, if not received depending on networked terminals
First data packet, it may be possible to because the MAC Address depending on networked terminals does not support multi-wad join, it is also possible to be because of transparent transmission industry
The other factors such as business exception lead to data transmission fails.
No matter depending on the MAC Address of networked terminals whether support multi-wad join, is transmitted in a manner of transparent transmission depending on networked terminals at this
When data, an invalid sub- device number is set by the sub- device number in transparent transmission parameter, receiving end all may be used depending on networked terminals
To receive the data of transmission.Based on this, further judgement is done for the case where not receiving the first data packet depending on networked terminals,
The second data packet can be sent depending on networked terminals, sets for the sub- device number in the corresponding transparent transmission parameter of second data packet
Two numerical value, the second value are an invalid sub- device number.If receiving at least one second data packet depending on networked terminals
And the first data packet is not received, it is determined that the MAC Address depending on networked terminals does not support multi-wad join.
Optionally, it is described view networked terminals in a manner of transparent transmission to its own send preset quantity the second data packet it
Afterwards, if described do not receive second data packet depending on networked terminals, the prompting message of transparent transmission service exception is shown.
Since the sub- device number in the corresponding transparent transmission parameter of the second data packet is invalid sub- device number, networking no matter is regarded eventually
Whether the MAC Address at end supports multi-wad join, can receive in a manner of transparent transmission depending on networked terminals to the pre- of its own transmission
If the second data packet of quantity, therefore, if both not receiving the first data packet depending on networked terminals, the second data are not received yet
Packet can then determine transparent transmission service exception.
Optionally, it after solving transparent transmission service exception, can be sent out in a manner of transparent transmission to its own again depending on networked terminals
Send preset quantity the first data packet, to judge whether the MAC Address depending on networked terminals supports multi-wad join.
Optionally, it is described view networked terminals in a manner of transparent transmission to its own send preset quantity the first data packet it
Afterwards, the view networked terminals send third data packet to its own in a manner of transparent transmission, include end mark in the third data packet
Know；It is described receive the third data packet depending on networked terminals after, judge described whether receive at least depending on networked terminals
One first data packet.
After the first data packet that view networked terminals send preset quantity in a manner of transparent transmission to its own, the view networked terminals
When obtaining the quantity of the first data packet received, it can not judge whether the first data packet has been sent.It is whole in view networking
End sends the first data packet and then sends the third data packet comprising end of identification, this receives third number depending on networked terminals
After packet, it can be learnt that the first data packet is all sent, the quantity of the first data packet received can be obtained at this time.It is logical
The quantity of the first data packet of the quantity for comparing the first data packet received depending on networked terminals and view networked terminals transmission is crossed,
The success rate of available data packet transmission, so as to obtain the situation of current network.
Optionally, described to can wrap in a manner of transparent transmission to its own first data packet for sending preset quantity depending on networked terminals
Include following two steps:
Step S11 sends the first data packet of preset quantity in a manner of transparent transmission to view networked server；First data
Wrapping in corresponding transparent transmission parameter includes: view networking number, between the view networking number and the MAC Address of the view networked terminals
With corresponding relationship；
It, can be the when sending the first data packet of preset quantity to view networked server in a manner of transparent transmission depending on networked terminals
Setting view networking number in the corresponding transparent transmission parameter of one data packet, this regards networking number as the MAC of the view networked terminals of receiving end
The corresponding view networking number in address.When sending data packet to its own depending on networked terminals, the view in transparent transmission parameter can be networked
Number is set as view networking number corresponding with the MAC Address of the view networked terminals.
Step S12 receives the first data packet of the preset quantity that the view networked server is sent.
After receiving the first data packet that view networked terminals are sent depending on networked server, joined according to the view in transparent transmission parameter
First data packet is sent to corresponding view networked terminals by network No. code, this depending on networked terminals can receive in a manner of transparent transmission to
Its own the first data packet sent.
It is noted that the Union of Central Vision of embodiment of the present invention network termination sends the second data packet to its own in a manner of transparent transmission
It can also be sent in the manner described above with third data packet.
