Refer to Fig. 1, the data transmission system structural representation based on timestamp that Fig. 1 provides for first embodiment of the invention.This system comprises: server 10 (server), client 20 (client) and memory device 30.
Particularly, this system can be divided into three layers by structure: mechanical floor, server layer, client tier, and wherein, mechanical floor comprises multiple memory device 30, and client tier comprises multiple client 20.Communication utility command row interface (cli between mechanical floor and server 10, command-lineinterface) mode, communication between server layer and client tier uses extend markup language (XML, ExtensibleMarkupLanguage) mode, network communication protocol uses transmission control protocol (TCP, and Simple Network Management Protocol (SNMP TransmissionControlProtocol), SimpleNetworkManagementProtocol), server and each client possess object model data in internal memory, client 20 can regularly upgrade to server 10 request msg.
Wherein, server 10, for when detecting that Data Update occurs memory device 30, judge in memory device 30, whether there is model object deleted, according to judged result, the renewal flag bit of the model object group at the model object place that Data Update occurs is set, and, current time stamp (the TS of model object and the place model object group thereof that Data Update occurs is set, TimeStamp) value, receive the request of data that client 20 sends, the historical time timestamp value of each model object group that client 20 records is comprised in this request of data, and according to the data of model object, this historical time timestamp value, this current timestamp value and this renewal flag bit tectonic response model object data, and by this response model object data, this current timestamp value and this renewal flag bit send to client 20.
It should be noted that, this model object refers to inhomogeneous memory cell in memory device, and this model object group refers to the set of similar model object.Such as, VDisk is had in storage array, POOL and RAID, each VDisk, POOL and RAID is called a model object, and all model objects of each class are denoted as VDiskList, POOLList and RAIDList altogether respectively, be called VDisk model object group, POOL model object group and RAID model object group.
Timestamp is an integer value, identifies the time at certain a moment uniquely.Server 10 is when managing multiple memory device 30, and need the model data of preserving multiple memory device 30 in internal memory, each model object adds a timestamp attribute, and each similar model object group is also with a timestamp attribute.Such as, for the logical volume model object (VDisk) on storage array, each logical volume model object has individual timestamp attribute, also has a timestamp attribute as similar all logical volume model object groups (being denoted as VDiskList).In system operation, by timestamp, server 10 and client 30 determine that the data of which model object need to upgrade.
This historical time timestamp value is the last time and carries out in the timestamp value that client 20 is preserved after exchanges data, and identical with the timestamp value that server after last exchanges data 10 is preserved, this historical time timestamp value is that server 10 sends to client 20.
Further, according to judged result, the renewal flag bit of the model object group at the model object place that Data Update occurs is set, and, arrange and the model object of Data Update and the timestamp value of place model object group thereof occur, be specially, if judged result is for there being model object deleted, the renewal flag bit (refresh) then arranging the model object group at the model object place that Data Update occurs is 1, represent and need the data refreshing all model objects, and the generation model object of Data Update and the timestamp value of place model object group thereof are all set to 0 as this current timestamp value.Such as, a model object VDisk in model object group VDiskList is deleted, the refresh flag bit then arranging model object group VDiskList is 1, and the TS value of model object group VDiskList and all model object VDisk is set to 0 and as this current timestamp value.If judged result is not for having model object deleted, the renewal flag bit then arranging the model object group at the model object place that Data Update occurs is 0, and the timestamp value that the model object group at the model object place of Data Update occurs is increased by 1 as this current timestamp value, and, the timestamp value of model object that Data Update occurs is set to this current timestamp value, as this current timestamp after the timestamp value that namely model object of Data Update and the model object group at place thereof occur all increases by 1.Such as a model object VDisk there occurs Data Update, the TS value of the model object group VDiskList at this model object VDisk place is added 1 as current TS value, and arranges TS
vDisk=TS
vDiskList, that is, the current TS value of model object VDisk and model object group VDiskList is all the TS value after increasing.
Further, up-to-date data are transmitted by server 10 in order to utilize timestamp, when client 20 asks up-to-date data to server 10, the historical time timestamp value that client 20 adds each model object group that client 20 self is preserved in request of data sends to server 10.Server 10 is according to the data of model object, this historical time timestamp value, this current timestamp value and this renewal flag bit tectonic response model object data, particularly, if this renewal flag bit is 0, the data configuration then selecting current timestamp value to be greater than the model object of this historical time timestamp value is the XML text of response model object data, such as, in the request of data of client 20, the timestamp value of model object group VDiskList is 5, and the timestamp value of model object group VDiskList is 9 in server 10, then all timestamp value in the model object VDisk of server 10 are greater than 5 all join in response model object data, and the timestamp value 9 of model object group VDiskList is sent to client 20.
If this renewal flag bit is 1, indicating that model object is deleted, then need the data of all model objects to send to client 20, therefore, is the XML text of response model object data by the data configuration of all model objects.And by this renewal flag bit 1, and there is the model object of Data Update and the timestamp value 0 of place model object group thereof and all send to client 20.
The exchanges data opposite equip. client 20 corresponding with server 10, for sending request of data to server 10, the historical time timestamp value of each model object group of client 20 self record is comprised in this request of data, and the response model object data that reception server 10 sends, there is the model object of Data Update and the current timestamp value of place model object group thereof, and, there is the renewal flag bit of the model object group at the model object place of Data Update, this response model object data is resolved according to this renewal flag bit, and carry out Data Update, and preserve this current timestamp value.
Further, according to this renewal flag bit, resolve this response model object data, and carry out Data Update and comprise:
If this renewal flag bit is 0, then resolve this response model object data to obtain the XML text of response model object data, and carry out corresponding Data Update according to this XML text, that is, model object data upgrade by correspondence.Such as, there is Data Update in model object VDisk, then the corresponding data upgrading VDisk.Now, this current timestamp value of preservation is than this historical time timestamp value large 1 of preserving before.
If this renewal flag bit is 1, then remove the data of all model objects in model object group corresponding in memory model, resolve this response model object data to obtain the XML text of response model object data, and, add in the model object group of this correspondence according to the data of this XML text by the model object that Data Update occurs.Now, this current timestamp value of preservation is 0.
In the embodiment of the present invention, by deleted according to whether there being model object during Data Update, difference arranges the renewal flag bit of the model object group that Data Update occurs, and difference arranges the generation model object of Data Update and the current timestamp value of place model object group thereof, determine that the data of which model object need to send client to and upgrade with this, thus reduce the transmission of hash, improve speed, reduce network and take.And owing to having filtered out most of useless redundant data, transmission be all critical data, add exploitation and engineering staff carries out the convenience of debugging.
