Description
Technical field
The invention belongs to technical field of the computer network, particularly relate to a kind of remote desktop computer awakening method based on cloud service.
Background technology
Current desktop computer is still in occupation of the major part in business equipment.Due to the needs of telecommuting, user has larger demand to being positioned at the desktop computer of enterprise, to carry out remote operation in non-office hours or place.In order to reach this object, when bench device is idle through being everlasting, still in start operating state, expended a large amount of electric energy, increased equally enterprise's electric power spending.In order to avoid this situation, can allow desktop computer sleep mode automatically and can Remote Wake Up in needs having shut down or the system of the desktop computer of sleeping just seems particularly important.
There have been at present a lot of schemes for solving Remote Wake Up problem, can be divided three classes:
The first kind has been introduced new hardware, such as new network interface card, mainboard etc., such as the remote wake up technology (RWT) of Intel.The network interface card that RWT needs sleeping device and a certificate server maintain stable TCP and are connected.When network interface card will wake-up master from this connection receives the information of waking up.Yet RWT is only effective to the equipment of Intel.
Equations of The Second Kind solution has adopted Intel Virtualization Technology.In this type of scheme, user's host desktop need to be installed virtual level (Hypervisor), the virtual machine that is mounted in virtual level upper strata of the actual use of user.When subscriber set is slept, virtual machine will be migrated to Entrust Server.When user returns, virtual machine will move to bench device again.The drawback of this type of solution is on all desktop computers, to need to install virtual level, and need to change operating system of user into virtual machine, and most of user is unwilling to accept the variation on such operational environment.
The 3rd class depends on agent equipment for waking the machine of sleep up.While waking up, agent equipment sends a Wake-on-Lan with destination host MAC Address (WOL) packet.Because WOL packet is only effective to Intranet equipment, so require must there be individual agent equipment in each subnet while applying this scheme.At present main and representationally have two kinds of methods in this type of scheme, one for arranging a dedicated proxies server in each subnet, its two be in subnet each also work desktop computer all bear proxy task, by distributed scheme, as long as there is equipment not sleep, just can be used for waking up other machines.Yet these two kinds of methods all exist very large deficiency, first method needs specific server, purchase and administrative expenses quite high, and in subnet only an agency also form Single Point of Faliure, if increase backup server, can increase more expense; Second method needs movable machine to detect frequently the state that other machines is known other equipment, carries out state synchronized, thereby causes the very big expense to CPU own and network.
Summary of the invention
Because the above-mentioned unfavorable factor of prior art, problem to be solved by this invention is to provide and does not a kind ofly need the environment that increases new hardware device, do not change enterprise work and in the situation that less fund cost and less CPU and network bandwidth expense, the effective technology of the inner desktop computer of Remote Wake Up enterprise or large organization, thus enterprise energy saved.Desktop computer at one's leisure can sleep mode automatically and is waken up smoothly when needed.
To achieve these goals, the online cloud lease service that the present invention utilizes cloud service supplier to provide, utilize cloud service to safeguard that in Intranet, the lasting network of finite population intermediary desktop computer (agent) connects, the Wake-on-Lan packet sending with object desktop computer MAC Address to target desktop computer by intermediary's computer when waking up carries out wake operation.
Remote desktop computer awakening technology based on cloud service mainly comprises cloud service end and client-side.Cloud service end can be configured in the cloud service of lease or privately owned Yun Zhong，Er enterprise in every desktop computer client-side can be installed and bear the task of waking other computers under same subnet up.
Cloud Server and client-side comprise the following steps:
Step 1: can be to cloud service end transmission time information before desktop computer starts or sleeps.Server end is recorded sleep and the start-up time of desktop computer, and records and store in database.Due to step 1 packet loss in a large number not, so can think that the state recording in database is substantially credible.
Step 2: when user need to wake the desktop computer in enterprise up, user uses the login cloud services such as home computer or mobile device.When the desktop computer in the own enterprise of Remote Wake Up is thought in the entering service of Verification System providing by login cloud service end as user, trigger cloud service and wake requirement up to the agent equipment transmission in the Intranet of place.
Step 3: cloud service is carried out Clustering according to the hypnograph in database to the desktop computer in Intranet, interior desktop computer has larger probability to sleep within the closer time on the same group.Cloud service is selected some (Ru Santai) intermediaries desktop computer based on group result.The machine that cloud service is recorded last sleep every day simultaneously or worked always, elects Yi Tai intermediary desktop computer equally as.These intermediary's desktop computers can be called as agent equipment.After user's login, the information that wake command needs, as the MAC Address of object desktop computer can be sent to from high in the clouds intermediary's desktop computer.
Step 4: whether agent equipment, from high in the clouds receives the MAC Address that need to wake desktop computer up, will send immediately WOL order test purpose desktop computer and can lead to by ping, thereby determine whether this desktop computer is waken up.Owing to there being many agent equipments to send WOL order for waking object desktop computer up, so do not need to resend.
Step 5: know that when the return information demonstration of ping object desktop computer is waken up, agent equipment can be shown and be waken up successfully by cloud service.
Step 6: in order further to guarantee availability, agent equipment will need to monitor other agent equipment states before will sleeping, if there are other agent equipments not in working order, need to send and warn to cloud service, report agent equipment disappearance, thus cloud service need to be selected new agent equipment.
Step 7: if when movable desktop computer number is less in current local area network (LAN) (as be less than total number 1/3rd), during agent equipment sleep mode automatically, can oneself stop, and send and be about to sleep information to high in the clouds, obtain could sleeping after cloud segment acknowledgement, thereby make agent equipment more reliable.
Step 8: if current active number of devices is less than required agent equipment number, directly waking the desktop computer of having slept up becomes new agent equipment.
As the above-mentioned remote desktop computer awakening technology based on cloud service, wherein, method in clustering algorithm in step 3 and step 6,7 is collectively referred to as " select---guarantee mechanism ", thereby this mechanism is moved always and guaranteed always to have movable agent equipment to wrap to wake up object desktop computer for forwarding WOL.
The present invention, the remote desktop computer awakening technology based on cloud service has following useful technique effect:
(1) can be effectively industry energy conservation, remote wake up technology makes user not need to allow the desktop computer of oneself always in running order, thus the electric energy having exhausted while having saved computer idle condition.
(2) the remote desktop computer awakening technology based on cloud service can effectively guarantee the validity of Remote Wake Up, adopts many agent equipments, selection---assurance mechanism etc. can effectively guarantee to have at least an agent equipment in running order.
(3) because the remote desktop computer awakening technology based on cloud service does not need the hardware more renewing or increases multiserver, do not need to increase extra charge, the cloud service of lease again can be shared for a plurality of subnets, thereby effectively reduce cost.Meanwhile, management work concentrates on cloud service end, and management cost is same effectively to be reduced.
(4), than other schemes, the remote desktop computer awakening technology based on cloud service can also take into full account safety problem.Login cloud service system need to carry out authentication, meanwhile, because wake operation is all to start to send by cloud service section, thereby when can avoid too much wake operation, carries out producing great electric power peak value.
(5) overwhelming majority work due to the remote desktop computer awakening technology based on cloud service all concentrates on cloud service end, make CPU and the network bandwidth occupancy of desktop computer itself lower, also make system on user's office computer, not move and can cause negative effect to normal use of user.

Embodiment
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.
According to the classification in background technology, existing remote desktop awakening technology can be divided three classes: increase new hardware, virtual environment and sleep agency.First two scheme or because thereby needs bring renewal and management, lower deployment cost for every machine increases hardware, or change that working environment affect user habit and desktop virtual environment is an individual problem to the support of some terminal equipments too completely.Adopt sleep agency's mode to become a kind of selection.
Fig. 1 is representative method in existing employing sleep agent way, need in each local area network (LAN), set up a station server as sleep agency, for the demand of Remote Wake Up, by proxy server, send Wake-On-Lan packet, and finally wake terminal desktop computer up.Because the basis of sleep agent way is Wake-On-Lan mechanism, all local area network (LAN)s all need to set up proxy server and realize Remote Wake Up.In each local area network (LAN), will increase new server, this has not only increased expense in purchase cost, deployment cost and management cost, has also increased new power consumption equipment.Meanwhile, consider Single Point of Faliure problem, thereby may need more server further to increase the seriousness of problem.
Another kind of sleep agency's the scheme that adopts need to not increase server as sleep agency in local area network (LAN), but the desktop computer that every activity in local area network (LAN) all becomes sleep agency, for this reason, every desktop computer needs random access other machines to determine that the state of other machines determines whether " adapter " thereby this desktop computer sends Wake-On-Lan packet by " adapter " machine when needs wake this desktop computer up.Because every desktop computer is all independently, know that the state of other machines need to ceaselessly be accessed other equipment, when desktop computer sum is more in local area network (LAN), not only increased the operating load of every desktop computer itself, also enterprise network is increased to occupancy simultaneously.
Fig. 2 is method of the present invention, drawback for such scheme, the method has increased a unified cloud service, but need in each local area network (LAN), not increase proxy server, thereby there is no to increase every cost that server brings and new electric power overhead issues in each local area network (LAN), utilize unified cloud service to obtain the state information of each desktop computer in local area network (LAN) simultaneously, and the agency of some in Maintain LAN, realize remote desktop and wake up and do not need agency ceaselessly to access other desktop computers to obtain state information.
Fig. 3 is the running of remote desktop awakening method.Control information is mainly carried out between desktop computer in cloud service and local area network (LAN), and in desktop computer, has the special installation of some to be called as agent equipment, is used for assisting cloud service to complete final wake operation.
The concrete steps of remote desktop computer awakening technology that the present invention is based on cloud service are as follows:
Step 1: can be to cloud service end transmission time information (as the process 1 in Fig. 3) before desktop computer starts or sleeps.Server end safeguards that a Hash table is for recording sleep and the start-up time of each desktop computer, and this Hash table is known as state table.And the historical information of state table is all stored in database.Because step 1 does not exist a large amount of packet losses, so that the state information of each desktop computer recording in database can be thought is substantially believable.
Step 2: when user need to wake the desktop computer in enterprise up, utilize the username and password getting from enterprise to sign in to cloud service end (as the process 2 Fig. 3).The application that the login of cloud service end and authentication service can directly utilize cloud itself to provide, as the dashboard of Openstack and keystone service.User logins behind high in the clouds, and triggering sends and wakes requirement up to the agent equipment in corresponding Intranet.
Step 3: cloud service is used clustering algorithm to carry out Clustering to the desktop computer in Intranet according to the hypnograph in database, and interior desktop computer has larger probability to sleep within the closer time on the same group.Cloud service is selected some (Ru Santai) intermediaries desktop computer according to group result, and the machine that cloud service is recorded last sleep every day simultaneously or worked always, elects Yi Tai intermediary desktop computer equally as.These desktop computers are called as agent equipment.After user's login, the information (as the MAC Address of object desktop computer) that wake command needs can be sent to from high in the clouds agent equipment (as the process 3 Fig. 3).
Concrete clustering algorithm, the K-clustering algorithm that the desktop computer of take is made cluster condition start-up time is example:
(a) if known number of categories is k; Choose k sample point as initial cluster center, be designated as z
1(l), z
2(l), z
3(l) ..., z
k(l), iteration sequence number l=1;
(b) use neighbour's rule all samples to be assigned to the k class w of each cluster centre representative
j(k), in, all kinds of comprised sample number is N
j(l);
(c) calculate all kinds of center of gravity (mean vector), and to make this center of gravity be new cluster centre,
(d) if z
j(l+1) unequal to z
j(l), return to step (2), continue iterative computation.
(e) if z
j(l+1)=z
j(l), iterative process finishes, and cluster result is now exactly optimum cluster result.
Step 4: agent equipment, from high in the clouds receives the information (MAC Address) that need to wake desktop computer up, can be used this desktop computer of ping order test whether to be waken up (in as Fig. 3, process 4) when transmission Wake-on-Lan packet wakes object desktop computer up.And due to more than one of agent equipment, multiple devices all can send WOL packet, so there is no need to resend WOl packet, guarantee that the desk-top function of object is successfully waken up.
Step 5: after ping order shows that object desktop computer has successfully been waken up, agent equipment can be informed user's wake operation success (as process in Fig. 35,6,7) by high in the clouds, thereby the desktop computer of user's Telnet oneself.
Step 6: in order further to guarantee availability, agent equipment will need to monitor other agent equipment states before will sleeping, if there are other agent equipments not in working order, need to send and warn to cloud service, report agent equipment disappearance, thus cloud service need to be selected new agent equipment.
Its concrete steps are as follows:
(a) agent equipment detects certain agent equipment sleep mode automatically, to high in the clouds, reports.
(b) beyond the clouds,, if the agent equipment of this disappearance is work agent equipment the latest, traversal state list finds new work to arrive agent equipment the latest in the desktop computer of still working again.
(c) if the agent equipment of this disappearance is selected from Clustering, to remaining, still at the desktop computer of working, carry out Clustering again, select the agent equipment making new advances.
(d) the new desktop computer of selecting of cloud service notice becomes new agent equipment.
Step 7: if when movable desktop computer number is less in current local area network (LAN) (as be less than total number 1/3rd), during agent equipment sleep mode automatically, can oneself stop, and send and be about to sleep information to high in the clouds, obtain could sleeping after cloud segment acknowledgement, thereby make agent equipment more reliable.Its concrete steps are as follows:
(a) in a subnet, movable desktop computer number is less than that three of sum/for the moment, system enters special state.
(b), under special state, when agent equipment will be slept, need keep operating state and to high in the clouds, send information.
(c) after the confirmation of high in the clouds, reselect new agent equipment and substitute former agent equipment work.
(d) high in the clouds return information is to former agent equipment, and this agent equipment enters sleep.
(e) if in this subnet vehicular equipment outnumber sum 1/3rd after, system exits special state.
Step 8: if current active number of devices is less than required agent equipment number, directly waking the desktop computer of having slept up becomes new agent equipment (as process in Fig. 3 8).
