Detailed Description
The following further description of the present invention, in order to facilitate understanding of those skilled in the art, is provided in conjunction with the accompanying drawings and is not intended to limit the scope of the present invention. In the present application, the embodiments and various aspects of the embodiments may be combined with each other without conflict.
Referring to fig. 1, an embodiment of the present invention provides a method for implementing resource reservation, including:
In this step, the reservation request includes: reservation start time, reservation end time, QoS requirement parameters, resources requested for reservation.
The QoS requirement parameters include the service level that the user wants to achieve, i.e. the requirement parameter corresponding to each resource. For example, the number of virtual CPU cores, the size of a memory, the disk space, the number of network cards, the number of ports, a network bandwidth, an Internet Protocol (IP) address, a Media Access Control (MAC) address, and the like.
Wherein the resource requesting reservation includes any one or more of the following: computing resources, storage resources, network resources, and the like.
The computing resources include Central Processing Unit (CPU) resources and memory resources, and the network resources include network bandwidth resources and the like.
In this step, fig. 2 is a schematic structural composition diagram of a system for implementing resource reservation according to an embodiment of the present invention. As shown in fig. 2, the federated server may obtain available resources in one or more data centers from the global information center, and may specifically obtain the available resources by sending an instruction to query the global information center for the available resources. The global information center may be a server.
The federated server may also obtain the available resources in the data centers from each data center. Specifically, the available resources may be obtained by sending an instruction for querying the available resources to each data center, and the available resources of each data center may be integrated.
Each data center includes a server and a device on which one or more resources reside. In each data center, the same kind of resources may be categorized in the servers of the data center by using Virtual Resource Containers (VRCs) to form a Virtual Resource list, and each entry in the Virtual Resource list includes an available state of each kind of Resource, that is, whether the kind of Resource is currently available.
Each data center can automatically detect the dynamic joining and exiting of resources, such as the starting and closing of the equipment where the resources are located. When dynamic joining and exiting of resources is detected, a server of the data center automatically updates a virtual resource list in the VRC.
The VRC receives an instruction for inquiring available resources from the joint server through the advance reservation interface and returns the available resources of the VRC to the joint server through the advance reservation interface.
In this step, the preset condition includes that the available resources of the data center include all resources in the reservation request.
In this step, the simple reservation request includes: reservation start time, reservation end time, QoS requirement parameters, resources requested for reservation.
Wherein the resource requested to be reserved in the simple reservation request is a part of the resource requested to be reserved in the reservation request.
In this step, when the reservation request is decomposed into simple reservation requests corresponding to the multiple data centers according to the obtained available resources in the multiple data centers, whether available resources exist in each data center can be respectively checked according to the types of the resources in the reservation request. For example, if the reservation request includes a computing resource, a storage resource, and a network resource, the reservation request may be decomposed into a plurality of three simple reservation requests, which are a simple reservation request corresponding to the computing resource, a simple reservation request corresponding to the storage resource, and a simple reservation request corresponding to the network resource, and then whether each data center has an available requested computing resource, an available requested storage resource, and an available requested network resource is determined according to available resources in each data center, and if so, the decomposed simple reservation request is sent to the corresponding data center.
For the requested resource in each simple reservation request, if there are multiple data centers that have the requested resource available, the formula can be followed
Calculating the deviation degree of one resource of each data center; and sending the simple reservation request to the data center with the minimum deviation degree obtained by calculation.
Wherein ε 2 is the deviation degree, m2 is the number of demand parameters contained in one resource in the reservation request, q2i2The i2 th demand parameter, r2, for a resource in the data centeri2The i2 th requirement parameter for a resource in the reservation request.
For example, if the demand parameters of the computing resources include the number of CPU cores and the size of the memory, m is 2, and if the demand parameters of the storage resources include the size of the storage space, m is 1.
And 102, the combined server sends each simple reservation request to a server of the corresponding data center.
In this step, after the server of each data center receives the simple reservation request, the server allocates the resource requested to be reserved in the simple reservation request to the user, and returns the allocated resource to the combined server.
According to the scheme of the embodiment of the invention, the request of available resources of a plurality of data centers is realized through the combined server, and when the resource of one data center is insufficient, the resources are distributed for the users from the plurality of data centers, so that the rejection rate of the reservation request is reduced.
Optionally, the method further includes:
when the combined server judges that one or more data centers meeting preset conditions exist, the combined server sends a reservation request to a server of one of the data centers meeting the preset conditions; the federated server returns to the user the allocated resources received from the server of one of the data centers that satisfies the preset condition.
The reservation request can be sent to any server in the data center meeting the preset condition, or the reservation request can be sent to the data center with the most idle resources in the data center meeting the preset condition.
Alternatively, the federated server follows a formula
Calculating the deviation degree of each data center, and sending the reservation request to a server of the data center with the minimum calculated deviation degree;
wherein ε 1 is the deviation degree, m1 is the number of demand parameters contained in the resource in the reservation request, q1i1The i1 th demand parameter, r1, for a resource in the data centeri1The i1 th demand parameter for the resource in the reservation request.
Optionally, the method further includes:
when the combined server receives a reservation request from a user, setting the advance reservation state of the user as a request reservation negotiation state; and after the joint server returns the allocated resources to the user, the pre-reserved state of the user is changed into a preset state.
Fig. 3 is a schematic diagram illustrating a change of an advance reservation state of a user according to an embodiment of the present invention. As shown in fig. 3, when the federated server receives a reservation request from a user, the advance reservation state of the user is a request reservation negotiation state; after the combined server returns the allocated resources to the user, successful negotiation is carried out, and the advance reservation state of the user is changed into a preset state.
Optionally, the method further includes:
after the joint server returns the allocated resources to the user, a reservation message is generated and put into a reservation queue; when the reservation starting time in the reservation message is reached, the combined server judges that the resources allocated in the reservation message are all available, changes the advanced reservation state of the user into an active state, informs the user that the required resources are bound, and informs the server for allocating the resources to set the resources allocated to the user as unavailable.
Optionally, when the reservation starting time in the reservation message reaches, if it is determined that the current advance reservation state of the user is the predetermined state, it is determined whether the resource allocated in the reservation message is available, and the subsequent process is continuously executed.
If the current advance reservation state of the user is judged to be a termination state or a revocation state, the process is ended.
As shown in fig. 3, when the reservation start time arrives, the advance reservation state of the user changes to the active state.
The reservation message comprises reservation starting time, reservation ending time, QoS requirement parameters, reservation types, reservation identifications and resources allocated to each data center.
The reservation type specifies whether the reservation message is a simple reservation message or a combined reservation message, the simple reservation message can be completed only by the resources of one data center, and the combined reservation message can be completed by the cooperation of the resources of a plurality of data centers.
The reserved identifier is an identifier allocated to the user after the joint server returns the allocated resources to the user.
When the reservation starting time in the reservation message is reached, the joint server reacquires the available resources of each data center, and judges whether the allocated resources are available according to the reacquired available resources, namely, whether the allocated resources exist in the reacquired available resources is searched.
After the method is adopted, the combined server can adopt a parallel method to process the reservation request, so that the processing speed is increased, and the user experience is improved.
Optionally, the method further includes:
when the federated server determines that some or all of the resources allocated in the reservation message are unavailable, the federated server proceeds to perform the step of acquiring available resources in one or more data centers.
Optionally, the method further includes:
when the reservation ending time in the reservation message is reached, the combined server changes the extraction reservation state of the user into a completion state and informs the data center for distributing the resources to release the resources distributed to the user;
or when the combined server judges that the preset termination condition is met, the combined server changes the advance reservation state of the user into a termination state, and informs the data center for distributing the resources to release the resources distributed to the user.
Wherein, the joint server judges that the preset termination condition is met, and the judgment comprises the following steps:
the federated server receives a termination request from the user.
Alternatively, a termination condition may be set in the federated server in advance, and when satisfied, the advance reservation state of the user is changed to a termination state. The termination condition may be any condition.
Optionally, the method further includes:
