Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 1, it illustrates a kind of flow chart of token subnet website cut-in method provided in an embodiment of the present invention,
It can include：
S11：The state of the channel for the token subnet to be accessed is intercepted, and judges whether state is to allow other websites to access
State, if then performing step S12, if otherwise performing step S13.
Multiple token subnets can be included in one Token Ring, the access problem in the present invention on website refers to be accessed
Website be linked into some token subnet in the Token Ring of website selection, a kind of token provided in an embodiment of the present invention
The execution subject of web site cut-in method can be corresponding token subnet website access device, and the device can be integrated in and treat
In the website of access, therefore a kind of execution subject of token subnet website cut-in method of the embodiment of the present application offer can be to treat
The website of access, accessed using performing subject as a kind of token subnet website that website to be accessed is provided the application in the application
Method illustrates.If website M is intended to access token subnet N, then website M is token subnet N website to be accessed.Now stand
Point M intercepts the state for the channel that token subnet N is used, and the state can be channel idle or channel busy, channel idle table
Bright now channel resource does not have occupied, and channel busy shows that now channel resource is occupied.Specific in actual conditions, channel
It is busy, show there is website to send data in now token subnet N, occupy channel resource, now website M is to add
Enter into token subnet；Caused by channel idle is then likely to be the frame period for the website for sending data, because website
Send data to send one by one, there is time interval between two frame data, this, which is spaced on channel, shows as channel sky
In the spare time, certainly it could also be possible that in order to reach the interval of time that certain purpose is specially reserved, channel is in the time interval
Idle.Website M listen for after channel status, it is necessary to judged, only when channel status to can be used for accessing other stations
During point, website M is possible to access the token subnet.Wherein, website M can be real-time sense to intercepting for channel, can also
It is to intercept once at regular intervals, but because the time of channel idle is ofer short duration, if using detecing at regular intervals
Listen intercepting method once, then carved at the beginning of idle time of channel may be missed, website M with just listen to free time when
To carve and calculate idle time of channel, the calculating to idle time of channel is not accurate enough, therefore preferably with real-time sense.
S12：Access request is sent to token subnet, and determines whether to receive the token of token subnet, if received
The token of token subnet, it is determined that the success of access token subnet, if being not received by the token of token subnet, it is determined that access
Token subnet fails.
After determining that now channel can be used for website M access token subnet N, website M sends access to token subnet N please
Ask, website M address can be included in access request, inform that token subnet N wants access now with website to be accessed.Specific
In realization, access request can show as a data frame, and referred to as request adds frame.After website M have sent access request, wait
Token from token subnet N, if obtaining the token, show to be successfully joined token subnet N, if there is no,
Illustrate to add failure.
S13：Return and perform step S11.
After website M determines that now channel is not useable for website M access token subnet N, it should continue to intercept token subnet N
Channel status information, untill listening to channel and accessing the token subnet available for website M.
In the embodiment of the present invention, website to be accessed intercepts the state of the channel for the token subnet to be accessed, and is listening to
The channel status of token subnet is when allowing the state of the website access token subnet, by sending access request to token subnet
Active request accesses, it is not necessary to waits the invitation of token subnet, also just have sent in the absence of token subnet and invite frame but do not have now
Need the situation of access website, save bandwidth.
A kind of token subnet website cut-in method provided in an embodiment of the present invention, intercept the channel for the token subnet to be accessed
State before, can also include：
It is 0 to set the currently active intercepted result number；
The state of the channel for the token subnet to be accessed is intercepted, and judges whether state is the shape for allowing other websites to access
State, it can include：
The state of the channel for the token subnet to be accessed is intercepted, if it is empty that the channel pre-set is listened in token subnet
Idle is grown, then the currently active intercepted result number is added into 1, and judges whether the currently active intercepted result number is equal to and preset
Value, if not, it is determined that state for allow other websites access state, if, it is determined that state for allow other websites
The state of access.
Website in token subnet realizes the transfer for the power for sending data by transmitting token, that is, obtains the station of token
Point can just send data.In multiple websites in a token subnet, it is home site to have one, and the home site is to set in advance
Set, its difference with other websites in the token for being used to transmit in token subnet is produced by the home site
, after home site produces new token, token is handed on, when token is communicated back to home site, the home site is just again
One new token of generation is used for transmission next time, and for the ease of expression, and home site can be transmitted to a token to being somebody's turn to do
This section of flow is referred to as a cycle when token transfers back to home site.The present embodiment is in the channel that token subnet N is used, each
One section of channel idle duration is preset in cycle, in the duration, channel is idle, and any website in token subnet is all
Data are not sent, therefore website M can send access request in the duration to token subnet N.Number is being sent in view of website
According to when the frame period time be present and the frame period time insufficient for website M complete access request transmission, so in order to protect
The idle time of channel that card website M is listened to is reserved duration, rather than the frame period time, can be the reserved channel
Free time length is set as：+ 2 times of time slots of frame period time.Because in a practical situation, in addition to reserved channel idle duration,
Channel is typically not in the situation that free time length is more than the frame period time, so being when website M detects idle time of channel
During+1 times of time slot of frame period time, then it may determine that and now detected reserved duration, as once effective intercepted result, remain
1 times of remaining time slot is used for sending access request.
Website due to being intended to add same token subnet may have multiple, multiple websites be present while send access request
Situation, but the access request sent simultaneously can collide, and access request may be caused to damage, and cause the plurality of access please
Asking can not be normally received by token subnet, finally all access failures.So in order to avoid the above situation, website M is intercepting letter
Before road, a random value can be chosen, it is assumed that the random value is 3, then when website M will detect 3 reserved free time,
Send access request because choose be random value, then two enter website and meanwhile choose arrive same value probability will be very
It is small, significantly reduce due to access request collision and caused by access failure probability.
In addition, it is worth noting that, in the prior art, in a cycle, invite new site to access the spent time
Expense is：The stand-by period after inviting website number in frame required time+token subnet × transmission broadcast is sent, and sends broadcast
Stand-by period afterwards is：Number of time slots × time slot, so the time overhead of prior art is：Send and invite frame required time+order
Website number × number of time slots × time slot in plate net, wherein, time slot of the prior art is that multiple websites to be accessed receive
It is used to compete the time for adding token subnet after inviting frame, each time slot can only allow a competition, and successfully website to be accessed connects
Enter, number of time slots is determined according to actual conditions, and each slot length is the same, therefore time slot is more, and token subnet is sent
Invite the time waited after frame longer.And the time overhead of the present invention is：+ 2 times of time slots of frame period time, frame is invited due to sending
Required time interval is more than the frame period time, thus except in token subnet website number and number of time slots be 1 it is this
Rare occasion, it is that the time overhead of the present invention is less than prior art in the case of thumping majority.
A kind of token subnet website cut-in method provided in an embodiment of the present invention, it is determined whether receive the order of token subnet
Board, it can include：
By timing sending out access request as initial time, if when duration obtained by timing is not more than preset duration
Receive token, it is determined that receive the token of token subnet, otherwise, it is determined that be not received by the token of token subnet.
In the specific implementation, token is also a data frame, token frame is can be described as, the token is contained in token to be reached
Website address, further comprises the website number in the now token subnet belonging to the token.Website M is intercepting the shape of channel
During state, the token from token subnet N may be received, but because now website M is not linked into token subnet N
In, so the website that website M after successfully token is parsed, be able to should reach according to the token included in the token received
Address judges that the token is not intended to be sent to oneself in fact, but website M can also be got after successfully token is parsed
The number of website in the token subnet N included in token, and successfully parsing token to abandon this not after obtaining above- mentioned information
One's own token.Therefore, such case of token is just obtained in the state procedure for intercept channel for website M, works as station
, it is necessary to wait for a period of time after point M transmission access requests, the time could be arranged to：The number of website in token subnet N × every
The maximum token that individual website allows holds the time.And do not receive token in the state procedure for intercept channel for website M
Situation, website M can not know the number of website in now token subnet N, be only capable of uniting during the state of channel is intercepted
Its neighbor site sum is counted, therefore, it is necessary to wait one of time after website M sends access request, waiting time can
To be arranged to：The maximum token that neighbor station points × each website allows holds the time, can also be arranged to other stand-by period,
Such as：The maximum token that 2 × neighbor station points × each website allows holds time etc..The maximum order that wherein each website allows
Board, which holds the time, to be set according to actual conditions, after the website in plate net obtains token in season, can send data, still
If the time for holding token reaches maximum token when holding the time, can only also stop sending even if also having data to send, etc.
Just continue to send when token is obtained next time.In addition, website M can intercept the token when state of channel is intercepted
Website M neighbor site in subnet, website M neighbor site are the website that can be communicated with each other with website M, so only
Website M neighbor site can just receive the access request of website M transmissions.Assuming that neighbor stations of the website M in token subnet N
Point has 3, then the maximum token that the time of wait could be arranged to 3 × each website permission holds the time, when website M is sent
Just started waiting for after access request, the token that website M transmissions can be received due to this 3 neighbor site adds frame, then
This 3 website cans transmit token to website M, but have crossed after maximum holds the time, and this 3 websites will no longer hold order
Board, also just without normal direction website M transmit token, if so this 3 website maximum tokens hold the time all pass by after do not connect yet
Receive token, then it is assumed that access failure.This method is by there is provided a rational waiting time, avoiding website M and waiting
Long or terminate to wait too early, improve website M access efficiency to a certain extent.
A kind of token subnet website cut-in method provided in an embodiment of the present invention, after determining the failure of access token subnet, also
It can include：
The currently active intercepted result number is reset；
The step of returning to the state for performing the channel for intercepting the token subnet to be accessed.
After website M has found that token subnet N sends access request, the access request is possible to lose during transmission
Or damage, then the website in token subnet N all can not effectively receive the access request, therefore website M can not be predetermined
The token from token subnet N is received in time, that is to say, that this access failure.After this access failure, Ke Yizai
The secondary state by intercepting channel, the just application access again when the state of channel is allows other websites to access.Due to this
Effective intercepted result number during access failure has equalized to value set in advance, if do not reset the number now, then
Hereafter 1 will be added by often listening to the channel idle duration number once pre-set, so the currently active number of intercepting can be big
In value set in advance, also it can not just add, so needing to reset effective intercepted result number after this access failure.
During actually realizing, when more access token subnet N failures of website M, website M, which can contemplate, seeks other token
The process for netting O, access token subnet O and access token subnet N is the same, be will not be repeated here.
A kind of token subnet website cut-in method provided in an embodiment of the present invention, after determining the failure of access token subnet, also
It can include：
The message of access failure is sent to the website for not accessing any token subnet.
Due to that access request is lost or damage causes this access failure of website M be present, then when website M is accessed
The situation of this access failure can be informed other websites by sending the message of access failure to other websites after failure,
It can so know that now token subnet N is not easy to access after remaining stations aware message, then can seeks other order
Plate net accesses, and has saved the time.
Come below so that certain website in certain concrete application scene accesses the flow of certain token subnet as an example to disclosed by the invention

In plate net H, wherein website B, C is website G neighbor site, after website G starts shooting, chooses a random value, chooses
Random value is 3, then begins listening for the state of token subnet H channel.Wherein, website A is home site, and token is spread out of from A
It is a cycle to transfer back to A again, and the duration of a channel idle is provided with each such cycle, this when a length of interframe
Every+2 times of time slots, 1 effective intercepted result is then recorded as whenever website G listens to the duration, when effective intercepted result is 3 times
When, website G sends access request to token subnet H, and the access that website B, C in token subnet receive website G transmissions please
Ask, in the case where the access request is smoothly received, website B, C know that now website G is intended to token accessed where oneself
H is netted, so website G address is added in the alternative space queue of oneself by website B, C, and places it in the head of the queue
Portion, when website G receives token the 1st time and without the transmission of data, but directly token is handed on, reception is arrived at a station
Website G is then moved to afterbody by the website for the token that point G is transmitted from the stem of oneself queue, and now website G is successfully aligned to biography
In the troop passed, after token is communicated back to home site A, website A can produce a new token, when new alternative space to website
During G, website G just starts to send data.
