Description

一种实现资源预留的方法和装置Method and device for realizing resource reservation 技术领域Technical field
本文涉及但不限于云计算技术和虚拟化技术，涉及一种实现资源预留的方法和装置。This document relates to, but is not limited to, cloud computing technology and virtualization technology, and relates to a method and apparatus for realizing resource reservation.
背景技术Background technique
网络(Web)服务作为目前最流行的分布式计算方式之一，提供了一种与操作系统无关、与程序设计语言无关、与机器类型无关、与运行环境无关的开放平台，实现网络资源的协作与共享。云计算平台集成的资源多以Web服务的形式向用户提供，许多计算任务往往需要大量的计算资源(包括中央处理器(CPU，Central Processing Unit)资源和内存资源)和存储资源协同工作来完成，有效地控制和保障这类计算任务的服务质量(QoS，Quality of Service)成为云计算面临的重要议题之一。由于云计算环境下资源的可获得性和性能的动态变化，未来预留时间段内资源的可获得性和性能难以得到保证，因此，将资源的提前预留作为一种QoS的保障机制引入到云计算环境下面临着挑战。全球网络论坛(GGF，Global Grid Forum)将资源提前预留定义为：用户与资源所有者经过协商，在指定时间段内获得的对资源的限制性访问权限。实际上，提前预留可以看作是云计算平台的一种承诺，在指定时间段内可以获得特定水平的服务。As one of the most popular distributed computing methods, network (Web) service provides an open platform that is independent of the operating system, independent of the programming language, independent of the machine type, and independent of the operating environment. With sharing. The resources integrated by the cloud computing platform are mostly provided to users in the form of Web services. Many computing tasks often require a large amount of computing resources (including Central Processing Unit (CPU) resources and memory resources) and storage resources to work together. Effectively controlling and guaranteeing the quality of service (QoS) of such computing tasks has become one of the important issues facing cloud computing. Due to the dynamic change of resources and performance in the cloud computing environment, the availability and performance of resources in the reserved time period are difficult to be guaranteed. Therefore, the early reservation of resources is introduced as a QoS guarantee mechanism. The challenge is in the cloud computing environment. The Global Grid Forum (GGF) defines resource reservation in advance as the restricted access rights to resources obtained by users and resource owners after negotiation within a specified time period. In fact, early reservation can be seen as a commitment of the cloud computing platform to obtain a certain level of service within a specified time period.
相关技术中，实现资源预留的方法大致包括：In the related art, the method for realizing resource reservation generally includes:
数据中心的管理服务器接收到来自用户的预留请求后，若判断出数据中心中的可用资源中存在预留请求中的全部资源，则从可用资源中为用户分配资源并向用户返回分配的资源。After receiving the reservation request from the user, the management server of the data center allocates resources for the user from the available resources and returns the allocated resources to the user if it is determined that all the resources in the reservation request exist in the available resources in the data center. .
相关技术中，当判断出数据中心中的可用资源中不存在预留请求中的全部资源时，管理服务器向用户返回拒绝消息，使得数据中心在资源不足时，预留请求的拒绝率较高。In the related art, when it is determined that all resources in the reservation request do not exist in the available resources in the data center, the management server returns a rejection message to the user, so that when the data center is insufficient, the rejection rate of the reservation request is high.

下面结合附图对本申请作进一步的描述，并不能用来限制本申请的保护范围。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。The present application is further described below in conjunction with the accompanying drawings, and is not intended to limit the scope of the application. It should be noted that the embodiments in the present application and the various manners in the embodiments may be combined with each other without conflict.
参见图1，本发明实施例提出了一种实现资源预留的方法，所述方法包括：Referring to FIG. 1, an embodiment of the present invention provides a method for implementing resource reservation, where the method includes:
步骤100、联合服务器接收到来自用户的预留请求，获取一个或多个数 据中心中的可用资源；Step 100: The federation server receives a reservation request from a user, and acquires one or more numbers. According to available resources in the center;
本步骤中，预留请求可以包括：预留开始时间、预留结束时间、QoS需求参数、请求预留的资源。In this step, the reservation request may include: a reservation start time, a reservation end time, a QoS requirement parameter, and a resource requested to be reserved.
其中，QoS需求参数可以包括用户希望达到的服务水平，即每一种资源对应的需求参数。例如，虚拟CPU核数、内存大小、磁盘空间、网卡数、端口数、网络带宽、互联网协议(IP，Internet Protocol)地址、媒体访问控制(MAC，Media Access Control)地址等。The QoS requirement parameter may include a service level that the user desires to reach, that is, a demand parameter corresponding to each resource. For example, the number of virtual CPU cores, memory size, disk space, number of network cards, number of ports, network bandwidth, Internet Protocol (IP) address, and media access control (MAC) address.
其中，请求预留的资源可以包括以下的任意一种或多种：计算资源、存储资源、网络资源等。The resource that is requested to be reserved may include any one or more of the following: a computing resource, a storage resource, a network resource, and the like.
其中，计算资源可以包括中央处理器(CPU，Center Process Unit)资源和内存资源，网络资源包括网络带宽资源等。The computing resources may include a central processing unit (CPU) resource and a memory resource, and the network resource includes a network bandwidth resource.
图2为本发明实施例实现资源预留的系统的结构组成示意图。如图2所示，联合服务器可以从全局信息中心中获取一个或多个数据中心中的可用资源，具体可以采用向全局信息中心发送查询可用资源的指令的方式来获取。其中，全局信息中心可以是一个服务器。FIG. 2 is a schematic structural diagram of a system for implementing resource reservation according to an embodiment of the present invention. As shown in FIG. 2, the federation server can obtain available resources in one or more data centers from the global information center, and can be obtained by sending an instruction for querying available resources to the global information center. Among them, the global information center can be a server.
联合服务器也可以从每一个数据中心中获取数据中心中的可用资源。具体可以采用向每一个数据中心发送查询可用资源的指令的方式来获取，并对每一个数据中心的可用资源进行整合。Federated servers can also get the resources available in the data center from each data center. Specifically, it can be obtained by sending an instruction for querying available resources to each data center, and integrating the available resources of each data center.
每一个数据中心可以包括服务器和一个或多个资源所在的设备。在每一个数据中心中，可以在数据中心的服务器中采用虚拟资源容器(VRC，Virtual Resource Container)将相同种类的资源进行归类，形成虚拟资源列表，虚拟资源列表中的每一个表项包括每一种资源的可用状态，即该种资源在当前是否可用。Each data center can include a server and one or more resources on which the device resides. In each data center, a virtual resource container (VRC) can be used to classify the same kinds of resources in a server in the data center to form a virtual resource list. Each entry in the virtual resource list includes each The available state of a resource, that is, whether the resource is currently available.
每一个数据中心能够自动检测资源的动态加入和退出，例如资源所在的设备的启动与关闭等。当检测到资源的动态加入和退出时，数据中心的服务器可以自动更新VRC中的虚拟资源列表。Each data center can automatically detect the dynamic joining and exiting of resources, such as the startup and shutdown of the device where the resource is located. When a dynamic join and exit of a resource is detected, the server of the data center can automatically update the virtual resource list in the VRC.
VRC通过提前预留接口接收来自联合服务器的查询可用资源的指令，并通过提前预留接口将自身的可用的资源返回给联合服务器。 The VRC receives an instruction from the federated server to query available resources through the advance reservation interface, and returns its available resources to the federated server through the advance reservation interface.
步骤101、联合服务器判断是否存在满足预设条件的数据中心，若不存在满足预设条件的数据中心，则根据获得的一个或多个数据中心中的可用资源，将预留请求分解为多个与数据中心对应的简单预留请求；Step 101: The joint server determines whether there is a data center that meets the preset condition. If there is no data center that meets the preset condition, the reservation request is decomposed into multiple according to the available resources in the obtained one or more data centers. a simple reservation request corresponding to the data center;
本步骤中，预设条件可以包括：数据中心的可用资源中包含预留请求中的全部资源。In this step, the preset condition may include: all resources in the reservation request are included in the available resources of the data center.
本步骤中，简单预留请求可以包括：预留开始时间、预留结束时间、QoS需求参数、请求预留的资源。In this step, the simple reservation request may include: a reservation start time, a reservation end time, a QoS requirement parameter, and a resource requested to be reserved.
其中，简单预留请求中请求预留的资源为预留请求中请求预留的资源的一部分。The resource reserved for reservation in the simple reservation request is part of the resource reserved for the request in the reservation request.
本步骤中，在根据获得的一个或多个数据中心中的可用资源，将预留请求分解为多个与数据中心对应的简单预留请求时，可以根据预留请求中的资源的种类分别查看每一个数据中心中是否有可用资源。例如，若预留请求中包括计算资源、存储资源和网络资源，则可以将预留请求分解多三个简单预留请求，分别为计算资源对应的简单预留请求、存储资源对应的简单预留请求以及网络资源对应的简单预留请求，然后根据每一个数据中心中的可用资源判断每一个数据中心是否有可用的请求的计算资源、可用的请求的存储资源、可用的请求的网络资源，如果有可用的请求的计算资源、可用的请求的存储资源或者可用的请求的网络资源，则将分解后的简单预留请求发送给对应的数据中心。例如，有三个数据中心，数据中1、数据中心2以及数据中心3，若数据中心1有可用的请求的计算资源，则将分解后的计算资源对应的简单预留请求发送给数据中心1；若数据中心2有可用的请求的存储资源，则将分解后的存储资源对应的简单预留请求发送给数据中心2；若数据中心3有可用的请求的网络资源，则将分解后的网络资源对应的简单预留请求发送给数据中心3。In this step, when the reservation request is decomposed into multiple simple reservation requests corresponding to the data center according to the available resources in the obtained one or more data centers, the reservation may be separately viewed according to the types of resources in the reservation request. Is there any resources available in each data center? For example, if the reservation request includes the computing resource, the storage resource, and the network resource, the reservation request may be decomposed into three simple reservation requests, which are respectively a simple reservation request corresponding to the computing resource and a simple reservation corresponding to the storage resource. Requests and simple reservation requests corresponding to network resources, and then, according to available resources in each data center, determine whether each data center has available requested computing resources, available requested storage resources, available requested network resources, if The available simple request resource, the available requested storage resource, or the available requested network resource are sent to the corresponding data center. For example, there are three data centers, data data 1, data center 2, and data center 3, if the data center 1 has available requested computing resources, the simple reservation request corresponding to the decomposed computing resources is sent to the data center 1; If the data center 2 has the requested storage resource available, the simple reservation request corresponding to the decomposed storage resource is sent to the data center 2; if the requested network resource is available in the data center 3, the decomposed network resource is used. The corresponding simple reservation request is sent to the data center 3.
可选地，对于每一个简单预留请求中请求的资源，如果有多个数据中心均有可用的请求的资源，可以按照公式
Figure PCTCN2017075199-appb-000002
计算每一个数据中心的该资源的偏差程度；将简单预留请求发送给计算得到的偏差程度最小的数据中心。Optionally, for each resource requested in the simple reservation request, if there are multiple data centers available for the requested resource, the formula may be followed.
Figure PCTCN2017075199-appb-000002
Calculate the degree of deviation of the resource in each data center; send a simple reservation request to the calculated data center with the least degree of deviation.
其中，ε为偏差程度，m为预留请求中的一种资源包含的需求参数的个 数，qi为数据中心中的一种资源的第i个需求参数，ri为预留请求中的一种资源的第i个需求参数，i为大于零的正整数。Where ε is the degree of deviation, m is the number of demand parameters included in a resource in the reservation request, q i is the i-th demand parameter of a resource in the data center, and r i is in the reservation request The i-th demand parameter of a resource, i is a positive integer greater than zero.
例如，计算资源的需求参数包括CPU核数和内存大小，则m取2，存储资源的需求参数包括存储空间大小，则m取1。For example, if the demand parameter of the computing resource includes the CPU core number and the memory size, then m takes 2, and the demand parameter of the storage resource includes the storage space size, then m takes 1.
步骤102、联合服务器将每一个简单预留请求分别发送给对应的数据中心的服务器；Step 102: The joint server sends each simple reservation request to the server of the corresponding data center.
本步骤中，数据中心的服务器接收到简单预留请求后，为用户分配简单预留请求中请求预留的资源，将分配的资源返回给联合服务器。In this step, after receiving the simple reservation request, the server of the data center allocates the resource reserved for request in the simple reservation request, and returns the allocated resource to the joint server.
步骤103、联合服务器向用户返回接收到的来自一个或多个数据中心的服务器分配的资源。Step 103: The federation server returns the received resources allocated by the server from one or more data centers to the user.
本发明实施例的技术方案，通过联合服务器实现一个或多个数据中心的可用资源的请求，在一个数据中心资源不足时，从多个数据中心中为用户分配资源，降低了预留请求的拒绝率。The technical solution of the embodiment of the present invention implements a request for available resources of one or more data centers by using a joint server, and allocates resources for users from multiple data centers when a data center resource is insufficient, thereby reducing the rejection of the reservation request. rate.
