Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present invention will be described in detail below with reference to specific examples.
Referring to fig. 1, fig. 1 is a schematic flowchart of a service node multiplexing method provided by an embodiment of the present invention, and is applied to a VCF controller, where the service node is understood as a service node on a service chain. The method comprises the following steps:
s101: acquiring a resource multiplexing request of a tenant for a first service node;
in an embodiment of the present invention, the VCF controller may provide a service node selection interface, and the tenant may select the first service node from the service node selection interface by using the user equipment, generate a resource multiplexing request for the first service node by the user equipment, and send the resource multiplexing request to the VCF controller; in addition, the tenant may also directly select the first service node from the service node selection interface on the VCF controller, and generate a resource multiplexing request for the first service node, which is not limited in the embodiment of the present invention.
S102: determining service equipment where a first service node is located;
s103: if the service equipment allocates resources for the first service node according to the first template, judging whether the resource utilization rate of the first service node reaches a preset threshold value; if so, S104;
here, the first template is a resource template for the first service node issued by the VCF controller, carries resource allocation information, and can be used to allocate resources for the first service node; resources may include CPU, memory, etc.
When the VCF controller issues a template to the service device, the VCF controller may provide the service node corresponding to the issued template for the tenant, and at this time, the service device does not allocate resources to the corresponding service node according to the issued template, that is, the allocation state of the service node corresponding to the issued template is unallocated resources, and the service node corresponding to the issued template is not actually created; when a tenant multiplexes the service node corresponding to the issued template, that is, when the VCF controller receives a resource multiplexing request for the service node corresponding to the issued template, an instruction is issued to instruct the service device to allocate resources to the corresponding service node according to the issued template to create the service node corresponding to the issued template, and at this time, the allocation state of the service node corresponding to the issued template is the allocated resources. In this case, the service node provided by the VCF controller and capable of being reused by the tenant includes: a service node to which resources have been allocated and a service node to which resources have not been allocated.
Based on this, when the VCF controller receives the resource multiplexing request for the first service node, since the VCF controller is responsible for issuing the template to the service device and instructing the service device to allocate the resource to the corresponding service node according to the template, it can be determined whether the service device where the first service node is located and the service device have allocated the resource to the first service node corresponding to the first template according to the first template.
In addition, in order to avoid the problem that the bearing capacity of the service node reaches the upper limit and affects the tenant to utilize the normal service of the user equipment as a result of multiplexing the same service node by a plurality of tenants, in other embodiments of the present invention, the VCF controller detects and records the resource utilization rate of the first service node when acquiring the resource multiplexing request of the tenant for the first service node to which the resource has been allocated; if the recorded resource utilization rate of the first service node reaches the preset threshold, it indicates that the bearing capacity of the first service node reaches the upper limit, other tenants are prohibited to continue multiplexing the service node, and S104 is executed; if the recorded resource utilization rate of the first service node does not reach the preset threshold value, it indicates that the bearing capacity of the first service node does not reach the upper limit, and allows other tenants to continue multiplexing the service node.
In other embodiments of the present invention, the resource multiplexing request may include the size of the resource that needs to be requested, and after the tenant multiplexes one service node, the resource utilization rate of the service node may be determined and recorded according to the size of the resource that needs to be requested, which is carried in the resource multiplexing request of the tenant; if the recorded resource utilization rate of one service node does not reach a preset threshold value, allowing other tenants to continuously multiplex the service node; and if the recorded resource utilization rate of one service node reaches a preset threshold value, prohibiting other tenants from continuously multiplexing the service node.
For example: the size of the memory resource corresponding to the first service node is 100MB, the preset threshold is 70%, a resource multiplexing request of the first tenant for the first service node is obtained, the size of the memory resource requested by the first tenant is 20MB, at this time, it can be determined that the resource utilization rate of the first service node is 20MB/100MB, 20% < 70%, and other tenants are allowed to continuously multiplex the first service node; acquiring a resource multiplexing request of a second tenant for a first service node, wherein the size of a requested memory resource of the resource multiplexing request is 60MB, at this time, the resource utilization rate of the first service node is 80% of (20+60) MB/100MB, and 80% > 70%, and other tenants are prohibited from continuously multiplexing the first service node.
S104: creating a second template aiming at a second service node, and issuing the second template to the service equipment;
here, the second service node has the same service type as the first service node, and the second template carries resource allocation information, which may be used to allocate resources to the second service node.
The service device stores the second template after receiving the second template, and the VCF controller may provide the second service node for the tenant.
S105: issuing an instruction for allocating resources for the second service node to the service equipment;
in this case, the service device may allocate resources to the second service node according to the resource allocation information carried by the second template, so as to create and operate the second service node.
S106: and issuing a second processing rule to the service equipment.
Wherein the second processing rule is to: and instructing the second service node to process the message sent by the tenant by using the user equipment.
Under the condition, the tenant is prohibited from multiplexing the first service node, the tenant is allowed to multiplex the second service node, and the influence on the tenant service is reduced. Specifically, if the service device receives a packet sent by a tenant using the user device, it may be determined that the received packet needs to be processed by the second service node according to the second processing rule, and then the packet is delivered to the second service node, so that the packet is delivered to the second service node for processing under the condition that the tenant does not perceive.
In an embodiment of the present invention, there are some service nodes that are not allocated with resources in the service device, and if the resource reuse request acquired by the VCF controller is for such a service node, refer to fig. 2, where fig. 2 is another schematic flow diagram of a service node reuse method provided in an embodiment of the present invention, and on the basis of fig. 1, after determining the service device where the first service node is located, the method further includes:
s201: if the service equipment does not allocate resources for the first service node according to the first template, issuing a command for allocating resources for the first service node to the service equipment;
in this case, the service device may allocate resources for the first service node according to the first template.
S202: and issuing a first processing rule to the service equipment.
Wherein the first processing rule is to: and indicating that the first service node processes the message sent by the tenant by using the user equipment.
Under the condition, the tenant is allowed to reuse the first service node, resources in the service equipment are fully utilized, and consumption and waste of the resources of the service equipment are effectively avoided. Specifically, if the service device receives a packet sent by a tenant using the user device, it may be determined that the received packet needs to be processed by the first service node according to the first processing rule, and then the packet is delivered to the first service node.
In an embodiment of the present invention, the first template may be issued by a service device when the service device is online on a VCF controller, and referring to fig. 3, before acquiring a resource multiplexing request of a tenant for a first service node, based on fig. 2, the method may further include:
s301: receiving an online request sent by service equipment; the online request includes the type of service device.
The type of the service device may be a FW (firewall) device, a GW (gateway) device, an LB (Load Balance) device, or the like.
Generally, after a service device establishes a connection with a VCF controller, the VCF controller receives an online request of the service device, and can identify the type of the service device.
S302: creating a first template for a first service node corresponding to the type of the service device;
after the type of the service equipment is determined, the service type which can be supported by the type of the service equipment can be determined, and then a first template corresponding to the service type supported by the service equipment and aiming at the first service node is created.
Here, the service type may include: FW service type, GW service type, LB service type, and the like.
It should be noted that one type of service device may support one service type, and may also support multiple service types. For example, FW devices and GW devices may generally support FW service types and GW service types, and LB devices may generally support LB service types only. In this case, if it is determined that the type of the service device is the FW device or the GW device, a template corresponding to the FW service type and a template corresponding to the GW service type need to be created; if the type of the service equipment is determined to be LB equipment, a template corresponding to the LB service type needs to be created.
S303: and issuing the first template to the service equipment.
In this case, the service device receives and stores the first template, and the VCF controller may provide the first service node for the tenant, but at this time, the service device does not allocate resources to the first service node according to the first template, and only when the tenant needs to multiplex the first service node, the service device allocates resources to the first service node according to the first template, thereby effectively reducing consumption and waste of resources of the service device.
In an embodiment of the present invention, the first template may also be created when the VCF controller receives a resource reuse request for a service node of the same service type as the service type corresponding to the first template, as the second template.
In other embodiments of the present invention, a service type may correspond to a plurality of service nodes, and after a tenant multiplexes one service node, the tenant may release the multiplexed service node, that is, the service node is not used any more. To avoid creating too many useless service nodes, the VCF controller may record the number of service nodes of the same service type, for example: and recording the number of service nodes with the same service type as the first service node.
In this case, when the resource utilization rate of the first service node reaches the preset threshold, before creating the second template for the second service node, the VCF controller may determine whether the number of service nodes currently having the same service type as that of the first service node is greater than 1;
if the number of the service nodes with the same service type as the first service node is determined to be larger than 1, detecting whether the resource utilization rates of other service nodes with the same service type as the first service node except the first service node reach a preset threshold, if so, indicating that no service node which is released by the tenant and is multiplexed and has the same service type as the first service node exists at present, and creating a second template; if not, it indicates that there is a service node which is released by the tenant and which is multiplexed by the tenant and has the same service type as the first service node, and the released service node can still be multiplexed by other tenants without creating a second template, and allows other tenants to continue multiplexing a third service node, which is a service node whose resource utilization rate does not reach the preset threshold among other service nodes having the same service type as the first service node, for example: issuing a third processing rule to the service equipment, wherein the third processing rule is used for: instructing a third service node to process a message sent by a tenant by using user equipment;
if the number of the service nodes with the same service type as the first service node is determined to be 1, that is, the service nodes with the same service type as the first service node only have the first service node, and the resource utilization rate of the first service node reaches a preset threshold, a second template is created.
In other embodiments of the present invention, in order to avoid that too many useless service nodes exist in the service device and occupy the resource of the service device, the VCF controller may further record the number of tenants currently multiplexing each service node and the duration of time for which each service node is not currently multiplexed; for example, the number of tenants currently multiplexing the first service node and the duration of the current time that the first service node is not multiplexed are recorded;
when the recorded tenant number for multiplexing the first service node is 0, indicating that the first service node is not multiplexed, detecting the duration of the first service node that is not multiplexed, and if the duration of the first service node that is not multiplexed reaches a preset duration, it can be said that the first service node is a useless service node;
in this case, if it is detected that the number of service nodes of the same service type as the first service node is greater than 1, indicating that a service node of the same service type as the first service node exists in the service device, which can be reused by the tenant, except for the first service node, a delete instruction for the first template may be issued to the service device, and the service device deletes the first template according to the delete instruction and releases the resource allocated to the first service node according to the first template;
if the number of the service nodes with the same service type as the first service node is detected to be 1, that is, only the first service node is the service node with the same service type as the first service node, in order to ensure that the tenant can quickly multiplex the service node with the same service type as the first service node, a release instruction for the first service node is issued to the service device, and the service device releases the resources allocated to the first service node according to the first template according to the release instruction, but does not delete the first template. In this way, the VCF controller may also provide the first service node for the tenant, and when the VCF controller receives the resource multiplexing request for the first service node again, the VCF controller may directly issue an instruction for allocating resources for the first service node to the service device, and instruct the service device to allocate resources for the first service node according to the first template.
In other embodiments of the present invention, in order to facilitate the VCF controller to process the service nodes, information such as allocation states of the service nodes, resource utilization rates, the number of service nodes, the number of tenants, duration of time that is not multiplexed, and the like may be correspondingly stored in one service node information table, as shown in table 1.
TABLE 1
If the resource utilization rate of a service node reaches a preset threshold, setting an 'operation' part corresponding to the service node in table 1 as a multiplexing stop, that is, prohibiting other tenants from multiplexing the service node, such as the service node 001 in table 1; if the resource utilization rate of a service node does not reach the preset threshold, setting the operation part corresponding to the service node in table 1 to be in use, that is, allowing other tenants to reuse the service node, such as the service node 003 in table 1;
if the service equipment allocates resources for the service node according to the template, setting an allocation state part corresponding to the service node in table 1 as activation, such as the service node 001 in table 1; if the service device does not allocate resources to the service node according to the template, the "allocation status" portion corresponding to the service node in table 1 is set to be inactive, such as the service node 002 in table 1.
By applying the embodiment, the VCF controller may obtain the resource utilization rate of each service node, that is, may sense the state of each service node, and after obtaining the resource multiplexing request for the first service node, may determine whether the resource utilization rate of the first service node reaches the preset threshold; when the resource utilization rate of the first service node reaches a preset threshold value, determining that the resource utilization rate of the first service node reaches an upper limit, forbidding the tenant to multiplex the first service node, creating a second template aiming at a second service node with the same service type as the first service node and issuing the second template to the service equipment, and indicating the service equipment to allocate resources for the second service node according to the second template, so that the tenant multiplexes the second service node, namely, the second service node processes a message sent by the tenant using the user equipment, and the resource utilization rate of the second service node does not reach the upper limit, thereby effectively reducing the influence on the tenant service.
