1) storage cluster identifies the data identical virtual machine page from snapshot document, then right with physical machine according to virtual machine
Should be related to and determine the virtual machine page for needing multicast or unicast, packet encapsulation is carried out to the virtual machine page；Wherein,
The virtual machine page that data are identical and corresponding virtual machine recovers in same physical machine is defined as into mode of unicast to pass
It is defeated, the virtual machine page that data content is identical and corresponding virtual machine recovers in different physical machines is defined as multicast side
Formula is transmitted；
2) storage cluster judges whether current packet to be sent is multicast packet, and if multicast packet, then notifying should
Multicast packet to be sent to physical machine be added in a multicast group, the multicast packet is then sent to the multicast group
In；Physical machine is parsed to the multicast packet for receiving, and the virtual machine page in multicast packet is returned to accordingly
Address；Correspondence physical machine is sent to unicast fashion if unicast packet, physical machine is by the void in the packet
The plan machine page returns to corresponding address；Wherein, the physical machine in multicast group be correspondence multicast packet to be sent to thing
Reason machine set.
Further, it is to the form that the data identical virtual machine page is carried out after packet encapsulation：[number of pages, { virtual machine volume
Number i, page number j } ..., { virtual machine numbering k, page number h }, content of pages].
Further, the step 2) in, storage cluster preferentially sends multicast packet, then sends unicast packet.
Further, for unicast packet, the preferential transmission content of storage cluster is identical and is sent to the same unicast of physical machine
Packet.
Further, the storage cluster adds multicast group and exits multicast group by control command notice physical machine, safeguards multicast
Physical machine in group be correspondence multicast packet to be sent to physical machine set.

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is done with specific embodiment below in conjunction with the accompanying drawings
Further illustrate.
We are mainly solved when Virtual Cluster needs rollback, because the network overhead for reading multiple snapshot documents introducings is big and rollback is prolonged
Problem big late.Our solution is as follows：
Virtual machine in Virtual Cluster often configures identical operating system, development library and application program, and this causes virtual machine in fortune
During row distributed program, often possesses identical data content.Therefore, by recognize virtual machine internal and between same page,
Same page is merged and is transmitted, the data volume of transmission required for can effectively reducing.Meanwhile, during Virtual Cluster rollback,
Virtual machine is often placed in different physical machines.Therefore, for the transmission of same page, we can by multicasting technology,
Come only transmit a data and while transmitting data on many physical nodes.As shown in Fig. 2 snapshot 1, snapshot 2 and fast
It is virtual machine 1, virtual machine 2 and the corresponding snapshot document of virtual machine 3 according to 3.In rollback, all deposited in snapshot 1 and snapshot 2
In page A, meanwhile, virtual machine 1 and virtual machine 2 start on main frame 1, therefore A will be merged and be transmitted with mode of unicast.
For page B, it is present in three snapshot documents, because virtual machine 3 starts on main frame 2, and it is virtual machine 1, virtual
Machine 2 starts on main frame 1, therefore page B needs to be sent to two physical machines, will be transmitted by multicasting technology.For the page
D and page E, it only has portion, therefore will be transmitted in the way of unicast.
Rollback flow.The rollback of Virtual Cluster is main to be implemented at storage device end, and storage device end is processed snapshot document,
Identify which page should unicast or multicast, the page encapsulated and is sent to thing by the page for needing multicast by udp protocol
Reason machine, and then sent using TCP for the page of unicast.The forwarding of packet is completed by data center network after encapsulation.Tool
For body, the rollback of Virtual Cluster is divided into three phases：Preparatory stage, multicast stage and unicast stage.
1) preparatory stage is mainly responsible for reading snapshot document, and identifies the data identical page by page contrast.Meanwhile,
Rollback position based on virtual machine specified by user, i.e. virtual machine recover to perform in which platform physical machine, judge to need multicast or
The page of unicast.Specifically, if two page (adhering to two virtual machines separately) data are identical, and two virtual machines are at same
Physical machine is recovered to perform, then the two pages will be transmitted in the way of unicast, the page A in such as Fig. 2.If two virtual
Machine recovers to perform respectively in two physical machines, then two pages are transmitted in the way of multicast, the page C in such as Fig. 2.For
The data identical page, no matter it is unicast or multicast, and be encapsulated into the page in packet by we.Data packet format is the [page
Number, { virtual machine numbering 1, page number 1 }, { virtual machine numbering 2, page number 2 }, { virtual machine numbering 2, page number 6 } ...,
{ virtual machine numbering k, page number k }, content of pages].
2) the multicast stage, the page of multicast or unicast is needed due to have identified, this stage is mainly responsible for needing multicast page
The transmission in face.For the page of multicast, step 1) in same page is encapsulated into packet.Simultaneously as virtual machine
(typically specified by user) with known to the corresponding relation of physical machine, therefore corresponding relation of the virtual machine page with physical machine can be known,
And then the physical machine that the data bag should be sent to can be obtained.The stage is responsible for notifying that physical machine is added in multicast group, finally by number
It is sent in multicast group according to bag.During next data bag pending, recalculate to be sent to physical machine, notify these physical machines
It is added in multicast group, packet is then issued into newly-generated multicast group.The process will be repeated, until institute in need group
The page broadcast all sends.Recipient, i.e., after physical machine receives multicast packets, packet is parsed, and foundation will be in the thing
The virtual machine (such as virtual machine numbering 1, virtual machine numbering 2) recovered on reason machine, obtains address that the page should fill (for example { virtually
Machine numbering 1, page number 2 }, { virtual machine numbering 2, page number 4 }, { virtual machine numbering 2, page number 7 }, virtual machine numbering 2,
Page number 9 } ... { virtual machine numbering 2, page number 14632 }), finally copy content of pages to corresponding address.
3) the unicast stage.The process will find the page not sent in snapshot document, and these pages include two classes：One class is content
It is identical, but the same page of physical machine is sent to, the page A in such as Fig. 2；Another kind of is the unique page of content, i.e.,
It is same without other page data contents, the page E in such as Fig. 2.This two classes page is all sent to thing by unicast technique
Reason machine.The first kind page is processed in transmission process first, the data packet format of the first kind page is identical with multicast packet form,
The treatment of recipient is also identical, and difference is sender and need not build multicast group (because only that a physical machine).Equations of The Second Kind
The form of packet is then simple, and it is [1 (the only one of which page), virtual machine numbering, page number, content of pages], and recipient connects
To after the packet, in copying content of pages the page number of the virtual machine specified in packet to.
After the completion of 3 stages, all of page has all been sent completely.The page is all being copied to recipient correspondence virtual machine
Corresponding page number after, recover virtual machine perform.
System architecture.Virtual Cluster rollback system framework based on multicast disclosed by the invention is as shown in Figure 3.Rollback client end
At storage device end, it is responsible for reading data in snapshot document, and identifies same page using scheduler, then according to use for administration
Virtual machine and physical machine corresponding relation that family is specified, which platform physical machine this is sent to calculate the packet after page-out encapsulation.Control visitor
Control command is responsible for sending in family end, and data client PkDataClien is responsible for encapsulating and sends packet, including multicast packet with
Unicast packet.Rollback service end is deployed in each physics generator terminal, and it is by controlling service end and data service end to receive control
Order and packet.Control command is mainly responsible for the generation of multicast group, that is, notify that physical machine adds multicast group and exits multicast group.
Packet includes：Unicast packet, multicast packet.
Cluster rollback agreement.As shown in figure 4, wherein there are two roles in the rollback agreement of Virtual Cluster：It is deployed in storage device
Rollback client, and be deployed in the rollback service end RBServer on every server, idiographic flow is as follows.
1st, keeper initiate rollback order " cluster rollback "；
2nd, rollback client to all rollback transmitting terminals send current data packet it is corresponding " multicast group information ".Rollback is serviced
After end receives control bag, if it needs to receive packet, it is added in group；If it in multicast group and is not needed
Packet is received, then exits multicast group, if ignoring the control command not in multicast group and if packet need not being received；
3rd, rollback service end is after adding or exiting multicast group, send to rollback client " multicast group acknowledge ", inform back
Rolling client executing is completed；
4th, rollback client delivers a packet to multicast group in multicast form；
5th, 2-4 steps are repeated, until the page for needing multicast is sent；
6th, " multicast terminates " to notify that multicast is completed rollback service end packet the transmission of rollback client；
7th, the page that rollback client will not send in snapshot document is packaged, and packet is sent to mode of unicast
Corresponding rollback service end；
8th, after being sent completely, " unicast terminates " to notify that the unicast of rollback service end packet is completed the transmission of rollback client；
9th, rollback service end safeguards an array to record the page number for receiving, and according to the memory size of virtual machine,
The unreceived page is searched, the page that then these are lacked to rollback client request.Such as virutal machine memory size is 40K (10
The individual page), if service end has only received certain page of virtual machine 1,2,5,6,8,9,10, then the page 3,4,7 is not yet received,
Missing is denoted as, it is necessary to the packet lost on last stage to rollback client request.
10th, rollback client is searched corresponding after the request missing page for receiving certain rollback service end from snapshot document
The page, is packaged into packet, and the rollback service end is then sent in the form of unicast；
11st, rollback service end replys " data validation " information after all of page is received；
12nd, rollback client receive that all rollback service ends reply " data validation " and after, inform that keeper virtually collects
Group's rollback is completed.
