Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
This example approach proposes the download scenarios based on DR election on BDCOM wireless platform, then by DR to originally
The wireless device edition upgrading scheme of other AP transmission version files (i.e. more new file) in collision domain.The program is realized same
AP under one collision domain only needs to download file (such as more new file), can be with afterwards by being transmitted again inside LAN
Cloud Server bandwidth pressure is effectively reduced, so as to solve the problems, such as that high-volume AP upgrades within the set time.
The specific implementation process of detailed description below once this example approach.
1.DR is elected.
DR is the key player in AP edition upgradings, and this programme downloads more new file by DR to Cloud Server, to other
Drother propagate more new file.
The random sequence number value that is generated after every device power starts is based primarily upon in this programme to elect DR.
Wherein, every AP device power can all generate a random sequence number value seq after starting, in this example approach with
The maximum AP equipment of seq values is used as DR.Here DR is elected using random seq values, every equipment is likely to select
Act turns into DR, also ensure that after DR fails, the possibility of DR Counterchange roles.
On this basis, for needing to specify certain equipment to turn into permanent DR under some occasions, this example approach further increases
Oil (gas) filling device priority value, for priority facility value here by setting manually, its priority is higher than random sequence number.It is excellent based on equipment
The priority level of first level value is higher than random sequence number value, can preferentially elect as DR.
In the case, DR election strategy is in this example approach：Priority facility (need to be set) manually>Equipment is random
Sequence number>Equipment Wan mouth IP address.
2. isolated in collision domain between distinct device.
If the AP more new files in a collision domain are identicals, the above-mentioned version liter based on DR election can be directly utilized
Level scheme, by the DR that elects to Cloud Server download version upgrade file in the collision domain, then into this collision domain
Other Drother propagate more new file.
If the AP equipment of different model in a collision domain be present, their more new file is inconsistent, in this case will
The above-mentioned edition upgrading scheme based on DR election can not directly be utilized.
On the other hand, this programme proposes a kind of subfield scheme, to isolating between distinct device in collision domain, pass through base respectively
Batch upgrade is carried out to the AP equipment in subdomain in the edition upgrading scheme of DR election.
The subdomain is particularly belonged in same collision domain and more new file MD5 values are the set of one group of AP equipment of identical.
That is, this programme is to belong in same collision domain and more one group of new file MD5 values identical rises without circuit as one
Level subdomain, and the AP equipment in subdomain is criticized with the edition upgrading scheme based on DR election respectively in each upgrading subdomain
Amount upgrading.
It follows that in same collision domain, DR is the role conception in subdomain, and the number of subdomain is individual equal to DR
Number.
File isolating problem in a collision domain between distinct device is efficiently solved by setting subdomain.
Carry out illustratively implementation process of this programme based on DR election progress edition upgrading below by way of a specific example.
Referring to Fig. 1 and Fig. 2, BDCOM wireless platforms AP upgrade-systems view and version text in this example are shown
Part distributes schematic diagram.As seen from the figure, the process of whole AP edition upgradings is as follows：
(1) as shown in figure 1, original state is DOWN after AP equipment starts, while a random sequence number seq is produced.And
Information of the equipment every 15 minutes latest editions by Http agreement request Cloud Servers.
(2) if cloud server end is provided with edition upgrading information, corresponding A P equipment ends will receive Http responses, including
Version number, md5 values and the download link of upgrade file, now AP equipment enters INIT state, while starts DelayTimer
(default timeout be 1000 seconds), other AP that delay timer ensures within this period can know the letter of latest edition
Breath.
(3) WAIT states are entered after DelayTimer time-out, AP equipment starts 60 seconds Wait timers in this condition, together
When also start and there are HelloTimer timer periods to be sent out multicast hello packet (default cycles 15 seconds).Because each AP is set
The standby time for entering INIT state is different, and this example regulation state after the AP of INIT state receives hello packet switchs to
WAIT, it is possible thereby to ensure that all AP equipment can carry out DR election at the same moment.
(4) DR election is carried out after WaitTimer time-out, unsuccessful AP equipment turns into Drother.The strategy of election is：If
Standby priority (need to manually set, be defaulted as 1)>Equipment random sequence number>Equipment Wan mouth IP address.
When carrying out DR election, the big equipment of priority turns into DR, if priority is consistent, the big equipment of random sequence number number
As DR, priority is consistent with random sequence number, then the big equipment of IP address turns into DR.
DR no longer changes easily Yi Dan elected successfully, and the equipment in INIT state is receiving the Hello of DR transmissions
Drother is automatically become after message.Only DR equipment ends lost contact (such as suspension or equipment fault), Drother is in 4 Hello
DR message is not received by cycle, then deletes the DR of aging, reenters the DR choosings that WAIT states carry out next round afterwards
Lift.
(5) DR equipment ends indicate BIN_OK in hello packet after download to Cloud Server download version
Position.Receive interior to DR sides request version file in the random interval of [0-15] second with Drother ends after BIN_OK messages.
Drother equipment ends detect version uniformity after asking, and carry out edition upgrading operation after being verified at once.DR ends are to institute
Some Drother neighbours also carry out edition upgrading operation (as shown in Figure 2) at once after sending version.
So far, all AP equipment in subdomain have been fully completed edition upgrading operation.
From upper example, DR election process experience DOWN->INIT->WAIT->Tetra- kinds of states of DR.In one subdomain
All AP upgradings only need DR to download once more new file, reasonably using the bandwidth resources in LAN, greatly reduce cloud clothes
The bandwidth pressure of business device, accelerates overall renewal speed.Meanwhile effectively solve the difference in a collision domain by subdomain and set
File isolating problem between standby.
