Description

Method, device and system for managing database table data

Technical field

This document relates to, but is not limited to, the field of network function virtualization technology, and in particular, a method, device and system for managing database table data.

Background technique

After the network function is virtualized, a VNF (Virtualized Network Function) generally includes multiple VMs (Virtual Machines) to provide traditional network services. One of the most important and core functions of the VNF is the Service Load Balancer (SLB), which monitors the load of each virtual machine in the VNF in real time and adjusts the number of signaling connections assigned to each virtual machine in a timely manner. And the volume of traffic, and if necessary, the flexible expansion of the VNF (ie increase or decrease the number of virtual machines).

Take the MGCF (Media Gateway Control Function) as an example. After the user configures a series of coupling resources in the OMC (Operation and Maintenance Centre), the SLB needs to evenly distribute these coupling resources. Multiple signaling processing virtual machines (referred to as VM _SIG for short) are recorded in the database table (we assume the table name is table_sctp). When the individual VMSIG is down and down, the SLB needs to migrate the coupled resources in the VM _SIG to other working VM _SIGs . The corresponding database tables also need to be adjusted synchronously. That is to say, in the SLB virtual machine (we are referred to as VM _SLB for short), the VM _SIG has a database table table_sctp, whose content is maintained by the VM _SLB and synchronized to other VMSIGs in real time. It can be seen that the database table table_sctp exists in multiple independent virtual machines at the same time. How to ensure the consistency of the database table data in different virtual machines becomes a problem that must be considered. Therefore, there is a need for a method, apparatus, and system for verifying data consistency of a virtual machine database table to solve the above-mentioned technical problems in the related art.

Embodiments of the invention

The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

The method for managing database table data provided by the embodiment of the present invention can implement consistency of database table data between different virtual machines. The method for managing database table data and each step of the embodiment of the present invention will be described in detail below.

First embodiment

As illustrated, data management database table according to the present embodiment performs a method of balancing traffic load in a virtual machine VM _SLB side Scheme 1, comprising:

Step S10: Perform digest calculation on the required verification data of the initial database table in the local database to obtain summary information.

Step S20: Send a checklist data request including summary information to the signaling processing virtual machine VM _SIG for the VM _SIG to check the required data of the corresponding database table in the database stored by the VM _SIG and the initial database table according to the summary information. Whether the data is consistent.

Optionally, the checklist data request further includes: a name of the initial database table, optionally, and a total number of records that need to check the data.

Step S30: After verifying the data to be inconsistent with the need to verify the data conditions, the received VM _SIG synchronization table sent data request to send an initial VM _SIG database table, for VM _SIG updates the corresponding database table according to the initial database tables .

This makes it possible to synchronize the corresponding database table stored by the VM _SIG with the initial database table stored by the VM _SLB . As shown in FIG. 3 and FIG. 4, the VM _SLB side may use the timer interval setting period T _check to perform digest calculation on the required check data of the initial database table, and then send a check table data request to the VM _SIG to This ensures the consistency of the database table data of the VM _{SIG and} the database table data of the VM _SLB , and improves the high reliability and self-recovery capability of the virtual network communication system.

As an optional embodiment, in step S10: performing digest calculation on the required verification data of the initial database table in the local database, to obtain the digest information, including: calculating by Message Digest Algorithm 5 (MD5) The MD5 value of the data to be checked is used, and the MD5 value is used as the summary information.

The MD5 algorithm ensures the integrity and consistency of information transfer between virtual machines. Because the summary information of the two pieces of the same data after the digest calculation is inevitably the same, even if the two pieces of different data are only one bit different, the summary information after the general digest calculation, especially the summary information after the MD5 calculation will be very different. If the data at both ends are different, the probability that the summary information obtained after MD5 is the same is very low. More importantly, the MD5 calculation is simple, and the obtained summary information has a fixed length, which is suitable for a virtual network communication system with high efficiency requirements.

In addition, the verification data needs to be the full table data of the database table table_sctp, or one of the fields (the specific verification data can be pre-defined in the service load balancing function virtual machine VM _SLB and the signaling processing virtual machine VM _SIG . ), based on the importance of the data. The steps to calculate the MD5 value include:

1) Sort all the records in the database table table_sctp, the basis of the sort is the unique keyword of the database table, such as the record number.

2) From the database table, you need to check the data, and store the serial of the data to be checked into the array NeedCheck[] of the unsigned char type. The following table is the serial type of the data to be checked. A schematic table of the deposit was made.

Table I

3) Perform MD5 calculation on the valid bytes in the array needCheck[], and obtain the MD5 value containing 16 bytes as summary information.

Optionally, the synchronization table data request mentioned above includes a name of the corresponding database table, so after sending the initial database table to the VM _SIG , the initial database table is sent to the VM after obtaining the initial database table according to the name of the corresponding database table. _SIG .

The obtained initial database table has the same name as the corresponding database table.

Second embodiment

As shown in FIG. 2, in this embodiment, based on the first embodiment, step S10: transmitting a checklist data request including digest information to the signaling processing virtual machine VM _SIG includes:

Step 200: Send the checklist data request directly to all VM _SIGs , which is the first type of transmission. Alternatively, sending a checklist data request to any VM _SIG such that the checklist data request is forwarded by the any VM _SIG to the remaining VM _SIG until all VM _SIGs receive the checklist data request, which Is the second way to send.

For the verification method using the first transmission method, we call it the star check. This shape check is characterized by the VM _SLB sending the check table data request to all VM _SIGs at the same time. A complete description of the star verification.

As shown in FIG. 3, the VM _SLB sets a timer T _Check to periodically check the consistency of the database table data, and the duration of the timer can be set to 30 seconds. When the timer expires, the VM _SLB uses MD5 to calculate the MD5 value of the check data and sends a checklist data request 101 to all VM _SIGs . Optionally, the checklist data request needs to carry both the name of the initial database table and the total number of records that need to be verified.

Then, after receiving the checklist data request 101, the VM _SIG locates the corresponding database table, and first checks whether the verified data and the total number of records that need to be verified are the same. If the total number of records is different, it is necessary to reacquire from the VM _SLB . Synchronized table data. If the total number of records is the same, the MD5 values of the two are further checked. If they are the same, the table data of the two is consistent, and no response is returned to the VM _SLB , and the verification ends.

If the data to be verified in a VM _SIG is different from the total number of records or MD5 values that need to be verified, the VM _SIG actively sends the synchronization table data request 102 to the VM _SLB to request to resynchronize all data of the database table data, and synchronize The name of the database table needs to be carried in the table data request.

After receiving the synchronization table data request 102, the VM _SLB resends the entire contents of the initial database table table_sctp to the VM _SIG through the synchronization table data message 103.

After receiving the synchronization table data message 103, the VM _SIG first clears the data in the corresponding database table, and then replaces the entire content of the initial database table with the corresponding coupling information, and the verification ends.

The second method of verification, validation we call chain, the chain verification feature is the VM _SLB checking table data request transmitted to only one of the VM _SIG, then down a VM _SIG forwarded by the VM _SIG The checklist data request is received until all VM _SIGs receive the checklist data request. The following is a detailed description of the entire flow of the chain check in conjunction with FIG.

As shown in FIG. 4, the VM _SLB sets a timer T _Check to periodically check the consistency of the database table data, and the duration of the timer can be set to 30 seconds. When the timer expires, VM _SLB desired value using the MD5 checksum MD5 calculation data, and transmits the data request checking table 101 to which a VM _SIG, may be all stored VM _{_SLB} VM _SLB smallest number, FIG. First sent to VM _SIG 1. It should be noted that the checklist data request also needs to carry the name of the initial database table and the total number of records that need to be verified.

After receiving the checklist data request 101, the VM _SIG 1 first sends the checklist data request to the VM _SIG 2, which is the second smallest. Then perform verification of the virtual machine: locate and find the corresponding database table, and check whether the total number of records and the MD5 value of the verification data and the data to be verified are the same. If they are the same, the table data is consistent, and the VM _{SLB is not required.} Reply to any response, this verification is over.

If the data to be verified stored in a VM _SIG is different from the total number of records or MD5 values that need to be verified, such as VM _SIG 2 in FIG. 4, it is necessary to actively send the synchronization table data request 102 to the VM _{SLB to} request resynchronization of the database. The content of the table data, similarly, the name of the corresponding database table needs to be carried in the synchronization table data request 102.

The VM _SLB receives the synchronization table data request 102, and resends the entire contents of the initial database table table_sctp to the corresponding VM _SIG 2 through the synchronization table data message 103.

The VM _SIG 2 receives the synchronization table data message 103, first clears the data in the corresponding database table, and then replaces the entire contents of the received initial database table into the corresponding database table, and the verification ends.

Compared to the star check, the chain check is that each VM _SIG sends a checklist data request to the next VM _SIG instead of being uniformly sent by the VM _SLB to all VM _SIGs , so when the number of VM _SIGs is large, Chain verification can reduce the load on the VM _{SLB to} send and receive messages.
