Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a resource management method, a sending end device, and a receiving end device.
Background
At present, a common network element, i.e. a disaster recovery scheme, is an N + M group Pool scheme, where N is a network element required for carrying a service, and M is a redundant network element (M may take different integer values according to different disaster recovery requirements of network elements with different services). For example: VNF1/2/3 is three network elements of a certain service, and VNF4 is a redundant network element of the service. In normal operation, VNFs 1/2/3 carry traffic, and VNF4 is standby, or VNFs 1/2/3/4 respectively carry traffic in proportion. If VNF1 fails, VNF2/3/4 carries all services, and monitors the Network element service load, and if an occasional burst traffic during the failure recovery exceeds the Network element service load threshold, a standby capacity expansion server may be used to start an elastic capacity expansion mechanism on the premise of the NFV (Network Function Virtualization) technology. After the VNF1 fault is recovered, Pool is added again, and the VNF1/2/3/4 recovers the original service bearer mode (if the capacity is expanded and the resources are occupied, the capacity can be automatically reduced or manually released). In the NFV scenario, a traditional network element N + M group Pool disaster recovery mode is used, and for the network element disaster recovery of a certain service, the total amount of the required redundant resources is: the redundant network element resource demand + the standby capacity expansion resource demand corresponding to the burst traffic. At present, a plurality of services are deployed in a large core data center in a virtualized manner, and each service requires N + M Pool disaster recovery groups, which causes a large amount of redundant resource requirements and resource waste.
A plurality of service Network elements are usually deployed in a data center, when the service Network elements are deployed in AN N + M group Pool mode, the resource utilization rate is low, and the service Network elements comprise resources such as servers, IP (Internet Protocol), V L AN (Virtual local Area Network), bandwidth, power, space and the like, as shown in figure 1, two main reasons of low resource utilization rate are that first different service Network elements all have own redundant Network elements, the probability of simultaneous failure of two or more service Network elements is extremely low, a sub-service deployment redundant Network element consumes a large amount of resources such as IP, V L AN and servers and reduces the whole resource utilization rate, and second, the standby capacity expansion servers of different services have low utilization rate (the probability that burst flow is generated when the Network elements fail and the current Network element cannot bear load at the same time), and the resource utilization rate of the sub-service type server is reduced.
Therefore, a method for resource management, a sending end device and a receiving end device are needed, which can form a unified disaster-tolerant resource pool by integrating resources required by different service network elements during disaster tolerance, reduce the resource redundancy, and perform reasonable management and allocation on the resources.

As shown in fig. 3, an embodiment of the present invention provides a method for resource management, which is applied to a virtual resource manager VIM, and specifically includes the following steps:
step S11, obtain the first resource capacity of the standby resource pool and the second resource capacity required after the network element failure.
In step S11, as shown in fig. 2, the first resource capacity may include a third resource capacity of a redundant resource pool and a fourth resource capacity of a spare extended resource pool, respectively, or the third resource capacity and the fourth resource capacity in the first resource capacity may be combined into a total capacity in a resource pool. The third resource capacity is the total capacity of the redundant servers in the redundant resource pool, and the fourth resource capacity is the total capacity of the standby capacity expansion servers in the standby capacity expansion resource pool. The redundant resource pool can be used as a redundant network element, and the standby capacity expansion resource pool can expand capacity when a plurality of network elements are in fault or burst flow.
The setting of the redundant resource pool cancels the setting of the redundant network element in each type of service network element, and provides a uniform and shared redundant resource pool for each type of service network element. The setting of the standby capacity expansion resource pool cancels the setting of the standby capacity expansion server, and provides a uniform shared standby capacity expansion resource pool for various types of service network elements.
Step S12, generating a first instruction to open the standby server or a second instruction to close the standby server according to the size relationship between the first resource capacity and the second resource capacity.
Step S13, sending the first instruction or the second instruction to a physical resource manager PIM.
When the standby server needs to be started, a first instruction for starting the standby server can be sent to the PIM by comparing the first resource capacity with the second resource capacity, so that the PIM controls the corresponding standby server to be started; when the standby server is idle, the standby server which is not needed to be used can be closed, and a second instruction for closing the standby server can be sent to the PIM, so that the PIM controls the corresponding standby server to be closed, resource waste caused by the idle standby server is avoided, and the resource utilization rate is improved.
In the foregoing embodiment of the present invention, the third resource capacity is a maximum value of redundant resource capacities required by each of the multiple types of network elements; the fourth resource capacity is a maximum value of the spare capacity-expansion resource capacity required by each type of network element in the multiple types of network elements.
The method for acquiring the third resource capacity comprises the following steps: and acquiring the redundant resource capacity required by each type of service network element, comparing the redundant resource capacity required by each type of service network element, and taking the maximum value in the total quantity of the multiple redundant resources as the third resource capacity, namely the total capacity of the redundant server. The method for acquiring the fourth resource capacity comprises the following steps: the method comprises the steps of obtaining the standby capacity-expansion resource capacity required by each type of service network element, comparing the standby capacity-expansion resource capacity required by each type of service network element, and taking the maximum value of the standby capacity-expansion resource capacities as a fourth resource capacity, namely the total capacity of a standby capacity-expansion server.
In an embodiment of the invention, after the step S11, the method further includes:
and after the network element fails, transferring the service of the network element to a server corresponding to the third resource capacity for bearing according to the second resource capacity.
After the network element fails, the service is switched to the other network elements of the service, and the other network elements of the service dynamically expand the resources by using the server corresponding to the third resource capacity, that is, the redundant server, so that the redundant server bears the service, and the processing capacity of the redundant server can be enhanced. And if the fault occurs on other service network elements, the redundant server in the redundant resource pool is also used for bearing the service.
In a specific embodiment of the present invention, after a network element fails, according to the second resource capacity, a service of the network element is transferred to a server corresponding to the third resource capacity for carrying; and if the third resource capacity is smaller than the second resource capacity, transferring the service of the network element to a server corresponding to the third resource capacity and a server corresponding to the fourth resource capacity for carrying together.
After the network element fails, the service is switched to the other network elements of the service, and the other network elements of the service dynamically expand the resources by using the server corresponding to the third resource capacity, that is, the redundant server, so that the redundant server bears the service, and the processing capacity of the redundant server can be enhanced. And if the fault occurs on other service network elements, the redundant server in the redundant resource pool is also used for bearing the service. If the third resource capacity is smaller than the second resource capacity, that is, when the redundant server in the redundant resource pool cannot bear all the services, the services of the network element need to be transferred to the server corresponding to the third resource capacity and the server corresponding to the fourth resource capacity to bear the services together. And if the third resource capacity is larger than or equal to the second resource capacity, only transferring the service of the network element to a server corresponding to the third resource capacity for bearing.
The step S12 includes:
when the first resource capacity is larger than the second resource capacity, acquiring a fifth resource capacity of a server in an idle state in the standby resource pool and a sixth resource capacity of each standby server; generating a first instruction for starting the standby server according to the fifth resource capacity and the sixth resource capacity; wherein the sum of the total resource capacity of the standby servers which are started and the fifth resource capacity is greater than or equal to the first resource capacity.
Taking the physical CPU quantity as the resource measurement standard, but not limited to the CPU quantity, the usage amount of the memory and the hard disk, etc.: when the standby servers can be standby servers with the same resource capacity, the number of the standby servers to be started can be calculated, and the number of the standby servers to be started is as follows: the difference value obtained by subtracting the fifth resource capacity from the first resource capacity is divided by the resource capacity of one standby server, and the obtained value at this time needs to be rounded up, that is, an integer value is taken up, for example, the obtained value is 3.2, that is, 4 is taken as the number of standby servers that need to be started. When the standby server is a standby server with different resource capacities, the difference value of the first resource capacity minus the fifth resource capacity, and the total capacity of the standby server to be started needs to be greater than or equal to the difference value of the first resource capacity minus the fifth resource capacity, so that certain resources can be reserved, and other network element faults or other emergency situations can be prevented.
And when the sum of the total resource capacity of the started standby server and the fifth resource capacity is smaller than the first resource capacity, sending warning information to the PIM.
The standby servers may be standby servers with the same resource capacity, or standby servers with different resource capacities. In order to prevent other network element faults or other emergency situations, certain resources need to be reserved, the reserved resources need to be larger than or equal to the first resource capacity, and the reserved resources are in an idle state; when the sum of the total resource capacity of the started standby server and the fifth resource capacity is smaller than the first resource capacity, that is, the sum of the free resources in the standby resource pool and the resources of the started standby server is smaller than the first resource capacity, the reserved resources are insufficient, and warning information needs to be sent to the PIM to notify an administrator that the number of the servers is insufficient, and hardware capacity expansion is needed to increase the number of the servers.
The step S12 specifically includes:
when the first resource capacity is smaller than or equal to the second resource capacity, acquiring the second resource capacity and a sixth resource capacity of each standby server; generating a first instruction for starting the standby server according to the second resource capacity and the sixth resource capacity; wherein the total resource capacity of the standby servers that are turned on is greater than or equal to the second resource capacity.
Taking the physical CPU quantity as the resource measurement standard, but not limited to the CPU quantity, the usage amount of the memory and the hard disk, etc.: when the standby servers can be standby servers with the same resource capacity, the number of the standby servers to be started can be calculated, and the number of the standby servers to be started is as follows: the second resource capacity is divided by the resource capacity of one standby server, and the value obtained at this time needs to be rounded up, i.e. an integer value is taken up, for example, the value obtained is 3.2, i.e. 4 is taken as the number of standby servers that need to be turned on. When the standby server is a standby server with different resource capacities, the total capacity of the standby server to be started needs to be greater than or equal to the second resource capacity, so that certain resources can be reserved, and other network element faults or other emergency situations can be prevented.
And when the total resource capacity of the started standby server is smaller than the second resource capacity, sending warning information to the PIM.
When the total resource capacity of the standby server which is started is smaller than the second resource capacity, that is, the total resource capacity of the standby server which can be started is smaller than the total resource capacity of the standby server which needs to be started, at this time, the reserved resources are insufficient, warning information needs to be sent to the PIM, an administrator is informed that the number of the servers is insufficient, hardware capacity expansion is needed to increase the number of the servers, and therefore it is guaranteed that enough online resources can deal with multiple network element faults or other emergency situations.
When the standby server is already turned on, the step S12 further includes:
acquiring a seventh resource capacity of each started standby server;
when the second resource capacity is smaller than the total resource capacity of the seventh resource capacity of the started standby server, acquiring a third difference value between the second resource capacity and the total resource capacity of the seventh resource capacity of the started standby server;
generating a second instruction for closing the standby server according to the third difference;
wherein the total resource capacity of the standby servers that are turned off is less than or equal to the third difference.
If the standby server may be a standby server with the same resource capacity, when the second resource capacity is smaller than the total capacity of the seventh resource capacity of the activated standby server, at this time, the standby server may be idle, which may cause resource waste, a third difference between the second resource capacity and the total capacity of the seventh resource capacity of the activated standby server needs to be obtained, according to the third difference, the number of the standby servers that need to be closed may be obtained, and the number of the standby servers that need to be closed is: the third difference is divided by the resource capacity of one standby server, and the value obtained at this time needs to be rounded down, i.e. an integer value is taken down, for example, the value obtained is 3.6, i.e. 3 is taken as the number of standby servers that need to be shut down, and then an instruction for shutting down the corresponding number of standby servers is generated. If the standby server is a standby server with different resource capacities, when the second resource capacity is smaller than the total capacity of the seventh resource capacity of the started standby server, the total capacity of the standby server to be closed needs to be smaller than or equal to the third difference, and at this time, a certain resource can still be reserved, so that other network element faults or other emergency situations can be prevented.
An embodiment of the present invention further provides a method for resource management, which is applied to a physical resource manager PIM, and as shown in fig. 4, the method includes:
step S21, receiving a first instruction sent by the VIM to open the standby server or a second instruction to close the standby server;
and step S22, controlling the standby server to be started according to the first instruction, or controlling the standby server to be stopped according to the second instruction.
When the first instruction is received, the PIM remotely triggers the corresponding standby server to automatically start up through a BMC (baseboard management Controller), and powers on the standby. And when a second instruction is received, the PIM remotely triggers the idle standby server to automatically shut down, so that resources are saved.
The method further comprises the following steps: and receiving warning information sent by the VIM, and giving an alarm according to the warning information.
When the sum of the total resource capacity of the standby server which is started and the fifth resource capacity is smaller than the first resource capacity, or when the total resource capacity of the standby server which is started is smaller than the second resource capacity, the reserved resources are insufficient, the VIM sends warning information to the PIM, and the PIM notifies an administrator that the number of servers is insufficient when receiving the warning information, so that the number of the servers needs to be increased through hardware capacity expansion.
In a specific embodiment of the present invention, as shown in fig. 9, taking each standby server as an example with the same resource capacity, after a network element failure, triggering capacity expansion, that is, triggering a redundant resource pool and a standby capacity expansion resource pool, and consuming resources in the redundant resource pool and the standby capacity expansion resource pool; the method comprises the steps that the VIM monitors resource use conditions in a redundant resource pool and a standby capacity expansion resource pool, when the reserved resource capacity is insufficient, the VIM calculates the number of standby servers needing to be started, and sends a first instruction for starting the number of the standby servers to the PIM, and the PIM controls the standby servers to be started; after the network element fault is recovered, the service is migrated back to the original server to carry out the bearing service, at the moment, the VIM monitors the resource use condition in the redundant resource pool and the standby capacity expansion resource pool, calculates the number of the standby servers needing to be shut down, and sends a second instruction for closing the number of the standby servers to the PIM, the PIM controls the standby servers to be shut down, so that the resources can be saved, and the waste is avoided.
In the embodiment of the invention, the capacity expansion requirements of different types of service resources can be integrated by utilizing the characteristic that the fault probability of different types of service network elements is low at the same time, a uniform redundant resource pool and a standby capacity expansion resource pool are provided for all service network elements in the data center, resources such as servers and IP can be greatly saved, and the standby servers which are idle beyond the requirements are powered off to save the resources.
