Specific embodiment
In order to make the invention's purpose, features and advantages of the invention more obvious and easy to understand, below in conjunction with the present invention
Attached drawing in embodiment, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described reality
Applying example is only a part of the embodiment of the present invention, and not all embodiments.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, Fig. 1 is the data transmission system structural representation based on timestamp that first embodiment of the invention provides
Figure.The system includes: server 10 (server), client 20 (client) and storage equipment 30.
Specifically, which can be divided into three layers by structure: mechanical floor, server layer, client tier, wherein mechanical floor packet
Multiple storage equipment 30 are included, client tier includes multiple client 20.Communication between mechanical floor and server 10 uses order
Row interface (cli, command-line interface) mode, the communication between server layer and client tier use expansible
Markup language (XML, Extensible Markup Language) mode, network communication protocol use transmission control protocol
(TCP, Transmission Control Protocol) and Simple Network Management Protocol (SNMP, Simple Network
Management Protocol), server and each client possess object model data, 20 meeting of client in memory
Periodically updated to 10 request data of server.
Wherein, server 10 are for judging to store in equipment 30 when detecting that data update occurs for storage equipment 30
No to have model object to be deleted, according to judging result, the model object group where the model object that data update occurs for setting
Update flag bit, and, setting occur data update model object and its place model object group current time stamp (TS,
Time Stamp) value, receive the request of data that client 20 is sent, each model recorded in the request of data comprising client 20
The historical time timestamp value of object group, and according to the data of model object, the historical time timestamp value, the current timestamp value and be somebody's turn to do
Update flag bit construct response model object data, and by the response model object data, the current timestamp value and this more
New flag bit is sent to client 20.
It should be noted that the model object refers to that inhomogeneous storage unit in storage equipment, the model object group are
Refer to the set of similar model object.For example, have VDisk, POOL and RAID in storage array, each VDisk, POOL and RAID
Be referred to a model object, all model objects of every one kind are denoted as VDiskList respectively altogether, POOLList and
RAIDList is referred to as VDisk model object group, POOL model object group and RAID model object group.
Timestamp is an integer value, uniquely identifies the time at certain a moment.Server 10 is managing multiple storage equipment
When 30, need to save the model data of multiple storage equipment 30 in memory, each model object adds a timestamp category
Property, each similar model object group also has a timestamp attribute.For example, for the logical volume model object on storage array
(VDisk), each logical volume model object has a timestamp attribute, (is denoted as similar all logical volume model object groups
VDiskList) also there is a timestamp attribute.In system operation, server 10 and client 30 are by timestamp come really
The data of which fixed model object need to update.
The historical time timestamp value is the last timestamp value save after data exchange in client 20, with upper one
The timestamp value that server 10 saves after secondary data exchange is identical, which is that server 10 is sent to client 20
's.
Further, according to judging result, the model object group where the model object of setting generation data update is more
New flag bit, and, the timestamp value of the model object that data update and its place model object group occurs for setting, specifically,
If judging result be have model object be deleted, be arranged occur data update model object where model object group more
New flag bit (refresh) is 1, the model pair for indicating to need to refresh the data of all model objects, and data update occurring
As and its place model object group timestamp value be disposed as 0 be used as the current timestamp value.For example, model object group
A model object VDisk in VDiskList is deleted, then the refresh mark of model object group VDiskList is arranged
Position be 1, and by the TS value of model object group VDiskList and all model object VDisk be set as 0 and it is current as this when
Between timestamp value.If judging result is deleted for no model object, the model occurred where the model object that data update is set
The update flag bit of object group is 0, and the timestamp value of the model object group where the model object that data update occurs is increased
1 is added to be used as the current timestamp value, and, the current time is set by the timestamp value that the model object that data update occurs
The timestamp value of the model object group of model object and its place that timestamp value, i.e. generation data update is used as after all increasing by 1 deserves
Preceding timestamp.Such as data update has occurred in a model object VDisk, by the model object where model object VDisk
The TS value of group VDiskList adds 1 to be used as current TS value, and TS is arrangedVDisk=TSVDiskList, that is, model object VDisk and model
The current TS value of object group VDiskList is all the TS value after increasing.
Further, in order to using timestamp by the server 10 newest data of transmission, when client 20 is to server
When the 10 newest data of request, going through for each model object group of client 20 itself preservation is added in client 20 in request of data
History timestamp value is sent to server 10.Data, the historical time timestamp value, the current time of server 10 according to model object
Timestamp value and the update flag bit construct response model object data, and specifically, if the update flag bit is 0, selection is current
The data configuration that timestamp value is greater than the model object of the historical time timestamp value is the XML text of response model object data, example
Such as, the timestamp value of model object group VDiskList is 5 in the request of data of client 20, and model object in server 10
The timestamp value of group VDiskList is 9, then all the adding greater than 5 by all timestamp value in the model object VDisk of server 10
Enter into response model object data, and the timestamp value 9 of model object group VDiskList is sent to client 20.
If the update flag bit is 1, indicate that model object is deleted, then needs to send the data of all model objects
It is the XML text of response model object data by the data configuration of all model objects therefore to client 20.And more by this
New flag bit 1, and the model object of generation data update and its timestamp value 0 of place model object group are all sent to client
End 20.
Data exchange opposite equip. client 20 corresponding with server 10 is asked for sending data to server 10
It asks, the historical time timestamp value of each model object group in the request of data comprising 20 self record of client, and receives server
The current time stamp of 10 response model object data, the generation data model object updated and its place model object groups sent
Value, and, the update flag bit of the model object group where the model object that data update occurs, according to the update flag bit solution
The response model object data is analysed, and carries out data update, and saves the current timestamp value.
Further, according to the update flag bit, the response model object data is parsed, and carries out data update and includes:
If the update flag bit is 0, XML of the response model object data to obtain response model object data is parsed
Text, and corresponding data update is carried out according to the XML text, that is, model object data are updated by correspondence.For example, mould
Type object VDisk occurs data and updates, then the corresponding data for updating VDisk.At this point, the current timestamp value ratio saved
The previously stored historical time timestamp value is big by 1.
If the update flag bit is 1, all model objects in memory model in corresponding model object group are removed
Data parse the response model object data to obtain the XML text of response model object data, and, according to the XML text
The data that the model object that data update occurs are added in the corresponding model object group.At this point, the current time saved
Timestamp value is 0.
Whether there is model object to be deleted in the embodiment of the present invention, when by being updated according to data, number occurs for difference setting
Model object and its place model that data update occurs according to the update flag bit of the model object group of update, and difference setting
The current timestamp value of object group determines that the data of which model object need to send to client and are updated with this, thus
