Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

In the description of the following examples, "plurality" means two or more unless specifically limited otherwise.
In the prior art, management of a VNFM cluster is generally implemented based on a consistent hashing algorithm, and when resources of the VNFM cluster need to be expanded, original VNFM devices and newly added VNFM devices are mapped to a hash ring again, so that the VNFM devices are uniformly mapped to the hash ring. However, since the management pressure of each VNFM device in the VNFM cluster is different, if the VNFM cluster is extended based on the prior art, the management pressure of the VNFM device cannot be reduced in a targeted manner.
In order to solve the above problems, in the node deployment method, the node deployment device, the electronic device, and the storage medium provided in the embodiments of the present application, a total amount of history processing messages of each VNFM device in the VNFM cluster is obtained; respectively determining the virtual node demand of the addressing interval corresponding to each VNFM device according to the total amount of the historical processing messages of each VNFM device and the preset capacity expansion factor of the newly added VNFM device; and deploying virtual nodes for the newly added VNFM equipment according to the virtual node demand of each addressing interval, deploying more virtual nodes corresponding to the newly added VNFM equipment on the addressing interval of the VNFM equipment with heavier load, positioning the virtual nodes corresponding to the newly added VNFM equipment on the addressing interval at a high probability when the upper-layer server issues the management message, and further forwarding the management message by using the newly added VNFM equipment to achieve the effect that newly expanded VNFM resources are preferentially used for sharing the work of the VNFM equipment with heavier load, so as to purposefully relieve the management pressure of the VNFM equipment.
The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a structure of a node deployment system on which the present application is based will be described:
the node deployment method, the node deployment device, the electronic device and the storage medium provided by the embodiment of the application are suitable for mapping newly-added VNFM devices to an addressing ring in a virtual node mode. As shown in fig. 1, the structural diagram of a node deployment system based on the embodiment of the present application is mainly composed of a VNFM cluster, a hash ring, and a node deployment device. Specifically, each VNFM device in the VNFM cluster is mapped to the hash ring in the form of a virtual node, and when the upper server issues the management message to the VNF device, the upper server needs to locate the target VNFM device through the hash ring and forward the management message based on the target VNFM device. When the VNFM cluster has a new VNFM device, the node deployment apparatus may be used to map the new VNFM device to the hash ring.
The embodiment of the application provides a node deployment method, which is used for mapping newly-added VNFM equipment in a VNFM cluster to an addressing ring in a virtual node mode. The execution subject of the embodiment of the present application is an electronic device, such as a server, a desktop computer, a notebook computer, a tablet computer, and other electronic devices that can be used for node deployment.
As shown in fig. 2, a schematic flow chart of a node deployment method provided in the embodiment of the present application is shown, where the method includes:
step 201, obtaining the total amount of the history processing messages of each VNFM device in the VNFM cluster.
It should be noted that each VNFM device in the VNFM cluster is mapped to the hash ring in the form of a virtual node, and in the prior art, one VNFM device generally corresponds to one virtual node. In order to ensure that the VNFM devices can perform management message forwarding in order, each virtual node in the hash ring is configured with a message queue for storing VNF management messages.
Specifically, a counter may be set for the message queue, and the counter count +1 may be set every time a management message enters the message queue. The message queue count result count corresponding to the VNFM device is the total amount of the history processing messages of the VNFM device.
Step 202, respectively determining the virtual node demand of the addressing interval corresponding to each VNFM device according to the total amount of the history processing messages of each VNFM device and the preset capacity expansion factor of the newly added VNFM device.
It should be noted that the capacity expansion factor is greater than 1, which may be specifically set according to an actual situation, and is used to mark how many virtual nodes the newly added VNFM devices are to be dispersed into. The virtual nodes in the embodiment of the present application are the same in nature as the virtual nodes, and are all hash nodes where VNFM devices are mapped in a hash ring, and in the embodiment of the present application, one VNFM device may correspond to one virtual node or α virtual nodes.
In particular, when multiple VNFM devices are mapped into the hash ring, the entire hash ring is partitioned into multiple addressing intervals, one for each virtual node. If the total amount of the history processing messages of a certain VNFM device is large, it may be determined that the management messages issued by the upper server frequently fall into the addressing interval corresponding to the VNFM device, and therefore, in order to purposefully relieve the management pressure of the VNFM device, the number of virtual node deployments in the addressing interval corresponding to the VNFM device may be increased.
Wherein, the virtual node is a proxy node of the newly added VNFM device.
It should be further noted that, in the embodiment of the present application, the newly added VNFM devices are mapped to multiple hash nodes, that is, multiple virtual nodes in the hash ring correspond to one newly added VNFM device at the same time, and the management message falls into an addressing interval corresponding to any virtual node, and the newly added VNFM device forwards the management message.
And step 203, deploying virtual nodes for the newly added VNFM equipment according to the virtual node demand of each addressing interval.
Specifically, the virtual node deployment number of each addressing interval may be determined according to the virtual node demand of each addressing interval, where the virtual node demand is the same as the virtual node deployment number, and then the virtual nodes are uniformly deployed to the corresponding addressing intervals.
On the basis of the foregoing embodiment, because different VNFM devices have different management pressures, in order to avoid a situation that a load of a VNFM cluster is inclined while the management pressure of the VNFM devices is specifically alleviated, as an implementable manner, in an embodiment, determining a virtual node demand amount of an addressing section corresponding to each VNFM device according to a total amount of history processing messages of each VNFM device and a preset capacity expansion factor of a preset newly added VNFM device includes:
step 2021, determining a load index of each VNFM device according to a total amount of the history processing messages of each VNFM device;
step 2022, determining a virtual node demand of the addressing interval corresponding to each VNFM device according to the load index of each VNFM device and the preset capacity expansion factor of the newly added VNFM device.
The load index of each VNFM device is proportional to the total amount of the history processing messages, and specifically, the load index refers to the proportion of tasks that a single VNFM device bears in a VNFM cluster.
Specifically, in an embodiment, the virtual node demand of the addressing interval corresponding to each VNFM device may be calculated according to the following formula:
Figure BDA0003277775440000081
wherein, numiIndicating the virtual node demand of the addressing interval corresponding to the ith VNFM device, alpha indicating the preset capacity expansion factor of the newly added VNFM device,

representing the load index of the ith VNFM device, CiRepresenting the total amount of history processing messages of the ith VNFM device, and n representing the total amount of VNFM devices in the VNFM cluster.
Fig. 3 is a schematic diagram of an exemplary hash ring structure provided in an embodiment of the present application. If the message QUEUE 1 has a count z, the QUEUE
Figure BDA0003277775440000083
Virtual node demand for addressing Interval 2
Figure BDA0003277775440000084
Virtual node demand for addressing Interval 2
Figure BDA0003277775440000085
Wherein, assuming that the total amount of the historical processing messages of the QUEUE-1 before capacity expansion is maximum, the number of virtual nodes obtained by the addressing interval 1 is the maximum, thereby realizing the self-adaptive new resource allocation during the capacity expansion according to the load condition of the VNFM equipment nodes.
Further, in an embodiment, when the virtual node is deployed, for each addressing interval of each addressing interval, the hash link point number of the addressing interval may be obtained; and deploying the virtual nodes to the corresponding hash ring nodes according to the number of the hash link points of the addressing interval and the virtual node demand of the addressing interval.
The hash link point number specifically refers to the number of idle hash nodes included in the current addressing interval, and the hash nodes can be used for deploying virtual nodes. Specifically, the virtual nodes can be uniformly distributed according to the number of hash link points in the current addressing interval and the virtual node demand in the current addressing interval.
Specifically, in an embodiment, the node interval between each virtual node may be determined according to the number of hash link points in the addressing interval and the virtual node demand in the addressing interval; and deploying the virtual nodes to the corresponding hash ring nodes according to the node intervals among the virtual nodes.
Specifically, the node interval between each virtual node may be determined according to the standard for uniform distribution of the virtual nodes, the number of hash link points in the addressing interval and the virtual node demand in the addressing interval, and the virtual nodes may be distributed according to the node interval between each virtual node and the virtual node demand, so as to achieve the effect of uniform distribution of the virtual nodes in the addressing interval.
Illustratively, if the current allocation criterion is a virtual node evenly dividedAnd if the number of the hash link points in the addressing interval is 10 and the required quantity of the virtual nodes in the addressing interval is 3, determining that the node interval between the virtual nodes is 2, wherein the node interval calculation formula based on the uniform distribution of the virtual nodes is as follows:
Figure BDA0003277775440000091
d represents the node interval between virtual nodes, h represents the number of hash link points in the addressing interval, and n represents the virtual node demand of the addressing interval. Specifically, the 3 virtual nodes may be respectively deployed at the 3 rd hash ring node, the 6 th hash node, and the 9 th hash node of the addressing interval.
If the number of hash link points in the current addressing interval is less than the required number of virtual nodes in the current addressing interval, the capacity of the hash ring can be expanded to ensure that the virtual nodes can be normally deployed.
On the basis of the foregoing embodiment, as an implementable manner, in an embodiment, since a current VNFM cluster has a situation where one VNFM device corresponds to multiple virtual nodes, when a total amount of history processing messages of each VNFM device in the VNFM cluster is a total amount of history processing messages of the virtual node corresponding to the VNFM device; the virtual node demand of the addressing interval corresponding to each virtual node can be respectively determined according to the total amount of the history processing messages of the virtual node corresponding to each VNFM device and the preset capacity expansion factor of the newly added VNFM device.
Specifically, under the condition that one VNFM device corresponds to a plurality of virtual nodes, the actual historical processing message total amount of the VNFM device is the sum of the historical processing message total amounts of the virtual nodes, in order to purposefully relieve the load pressure of the VNFM device, the historical processing message total amounts of the virtual nodes corresponding to the VNFM device may be directly obtained, then the virtual nodes are used as management units, the virtual node demand amount of the addressing interval corresponding to each virtual node is determined, and further the virtual nodes corresponding to the newly-added VNFM device are deployed according to the virtual node demand amount of each addressing interval.
Specifically, in an embodiment, since the management pressure of each VNFM device changes every time VNFM cluster expansion is performed, in order to clearly reflect the load change condition of the VNFM cluster after the expansion management and provide reliable load monitoring data for subsequent management work, the total amount of the history processing messages of each VNFM device may be cleared after the deployment of the virtual node is completed.
Specifically, each time virtual node is allocated once according to the total amount of the history processing messages of each VNFM device, the total amount of the history processing messages (count value) is cleared once, and the virtual nodes are counted again after allocation is completed.
To facilitate those skilled in the art to better understand the node deployment method provided in the embodiment of the present application, as shown in fig. 4, it is another exemplary hash ring structure diagram in the embodiment of the present application, where an addressing principle of a VNFM cluster is as follows:
each node in a VNF Manager (VNFM) cluster has a specific management IP, and the management IP is unique in the cluster, and each VNF Manager performs a discrete operation according to the management IP, where the specific discrete algorithm may be a hash value of an IP address string, and the operation method is code hash (IP). And constructing a Hash addressing ring in the VNF Manager cluster, wherein the number N of nodes in the addressing ring can be determined according to actual networking, each VNF Manager uses the Hash value to discretize the addressing ring again, and the algorithm is expressed as hash (device-N), namely each VNF Manager can be discretely distributed on the addressing ring and is positioned at the fixed position of the addressing ring.
Each management message that needs to be sent down to a VNF device needs to go through the addressing ring to find a uniquely determined service node. Each management message has a specific device-ID attribute (device-n). In the addressing process, hash operation is firstly carried out on device-n, the hash algorithm is consistent with the algorithm of VNFManager and is expressed by code-hash (device-n). After the message hash value code is obtained, the position of each management message in the addressing ring is determined using the position ═ code% N method. Fig. 5 is a schematic diagram of another exemplary hash ring structure provided in the embodiment of the present application, where if an addressing location is between VNF Manager-2 and VNF Manager-3, a corresponding management VNF Manager node, such as the VNF Manager-2 node in fig. 5, is found according to an addressing direction (which may be counterclockwise or clockwise) of the addressing ring, and a device management message is added to a message queue of VNF Manager-2 for waiting to be issued.
The hash ring provided by the embodiment of the application can be constructed based on a consistent hash algorithm, and the principle of the consistent hash algorithm is as follows:
the consistent Hash algorithm organizes the whole Hash value space into a virtual ring, for example, assuming that the value space of a Hash function H is 0-2 ^32-1 (i.e., the Hash value is a 32-bit unsigned shaping), wherein, as shown in fig. 6, the consistent Hash algorithm schematic diagram provided by the embodiment of the present application is shown.
The entire spatial circle is laid out in a clockwise direction, the point directly above the circle represents 0, and the first point to the right of the point 0 represents 1. And so on 2, 3, 4, 5, 6 … … up to 2^32-1, that is to say the first point to the left of point 0 represents 2^32-1, 0 and 2^32-1 coincide in the zero direction, this circle consisting of 2^32 points is called Hash circle.
Suppose there are 4 servers, server 0, server 1, server 2, and server 3, and in a production environment, these 4 servers must have their own IP addresses or host names, perform hash calculations using their respective IP addresses or host names as keys, and use the hashed result to modulo 2^32, i.e., hash (IP address of server)% 2^ 32. Finally, an unsigned integer number between [0,2^32-1] is obtained, and the integer represents the number of the server. Meanwhile, the integer is definitely between [0,2^32-1], a point must be corresponding to the integer on the hash ring, and the server can be mapped to the ring. The multiple servers are computed in this manner and each maps to a point on the ring so that each machine can determine its location on the hash ring.
