相关申请的交叉引用
本申请要求2012年9月25日提交的美国临时专利申请No.61/705,618的优先权权益,该申请的公开内容通过引用结合于此。
技术领域
本公开一般涉及数据处理,并且更具体地涉及软件驱动网络(SDN)中的负载分发。
背景
这一部分中描述的方法可被实现,但不一定是先前已经构想或实现的方法。因此,除非另外指出,否则不应当假定这一部分中描述的任一方法均仅仅由于其包括在这一部分中而取得成为现有技术的资格。
在典型的负载平衡场景中,负载平衡器(LB)(在本文中也被称为LB设备)作为由服务器群所托管的服务的前端,该负载平衡器将该服务作为虚拟服务表示给客户端。需要该服务的客户端可使用虚拟因特务协议(IP)地址和虚拟端口来将其分组寻址到该虚拟服务。例如,www.example.com:80是正被负载平衡的服务,并且存在托管该服务的服务器群。LB可配置有虚拟IP(VIP)(例如,100.100.100.1)和虚拟端口(VPort)(例如,端口80),该虚拟IP和虚拟端口进而被映射成处理该服务的服务器的IP地址和端口号。处理该域的域名服务(DNS)服务器可被配置成将分组分送给与此LB相关联的VIP和Vport。
LB将检查传入分组并且基于这些策略/算法将从服务器群中选择特定服务器,在必要时修改该分组,并将该分组转发至服务器。在从服务器返回的途中(可任选),LB将获得该分组,在必要时修改该分组,并将该分组转发回客户端。
通常需要放大或缩小LB服务。例如,可能需要基于当天的时间(例如,白天还是夜晚、工作日还是周末)来放大或缩小LB服务。例如,固定间隔的软件更新可导致可预测的网络拥塞,因此LB服务可需要被放大以处理突发的拥挤现象,并随后被缩小。该服务的普及可使得放大该服务的需要成为必要。当LB服务的性能特征可处理所需的缩放调整时,可在LB内处理这些情况。
然而,在许多情况下,需要将该性能增加到超过单个负载平衡设备可处理的性能。针对这种情况的典型方法包括基于物理机架的解决方案,其中卡可被插入和移除以处理这些服务要求。这些方法具有许多缺点,包括需要为机架预留空间、功率和价格以用于将来的需要。此外,单个机架仅可放大到其卡的最大容量。为了消除该不足,可尝试堆叠LB设备,并按需在这些设备之间发送话务。然而,由于各分组必须穿过多个LB以抵达将最终处理这些请求的实体,因此该方法也可具有诸如这些设备之间的链路成为瓶颈、增加的等待时间之类的缺点。
另一现有的解决方案是增加多个LB设备,在每一设备上为在后端的相同服务器创建各单独VIP,以及使用DNS来在这些服务器之中分发负载。当需要添加另一LB时,将另一条目添加到DNS数据库中。当需要移除LB时,将相应的条目从DNS数据库中移除。然而,该方法具有以下问题。DNS记录被高速缓存,并因此LB的添加/移除在其有效之前可较费时间。这在移除LB时尤其成问题,因为定向到该LB的数据可能丢失。跨LB的分发非常粗略并且不是话务知晓的,例如一个LB可能应接不暇而其他LB却可能是空闲的,一些客户端可能是较沉重的用户但最终却向同一LB发送请求,并以此类推。LB之间的分发可能不是LB容量知晓的,例如与LB2相比,LB1可能是强大得多的设备。因此,用于解决该问题的现有方案全部都具有其缺点。

详细描述
以下详细描述包括对附图的参考,这些参考形成该详细描述的一部分。这些附图根据示例实施例示出示图。这些示例实施例(在本文中也被称为“示例”)被足够详细地描述以使得本领域的技术人员能够实施本发明主题。可组合这些实施例,可利用其他实施例,或者可作出结构、逻辑和电改变,而不背离所要求保护的范围。因此,以下详细描述并不旨在作为限制,并且该范围由所附权利要求及其等效方案来限定。在本文中,使用术语“一”和“一个”(如在专利文献中常见的)以包括一个或一个以上。在本文中,术语“或”被用来指非排他性的“或”,使得“A或B”包括“A但非B”、“B但非A”以及“A和B”,除非另外指明。
本公开涉及通过使得LB服务和数据网络(诸如SDN)一起用于将分组递送给多个LB来实现负载平衡的高效方式。由于SDN知晓LB服务的要求,因此它可高效地将话务分发给LB。该方法允许同一虚拟服务被托管在多个LB上,而无需任何DNS改变。由于分组被直接递送到处理这些分组的LB,因此有最小的或没有等待时间影响。可基于LB能力、网络能力和当前负载来实现对到LB的流的细粒度分发。该方法还支持按需放大/缩小服务,以及促成对管理员对负载平衡的管理和操作。
在一些示例实施例中,LB和SDN元件之间可能正在运行使得SDN和LB交换关于如何分发话务的信息的协议,从而动态地插入转发规则以影响对能够执行这样的转发的设备的分组路径选择。可在路由器、交换机或其他设备上实现由LB控制的算法以影响话务控制。
为了确保数据流在来自多个厂商的异构交换机网络中的分发,可使用附加的技术。这些技术可利用控制器来计算源和目的地之间的路径,并在这些源和目的地之间的网络设备上对流进行编程。该性质可被利用来基于需求、和资源可用性等来智能地对流进行编程以放大/缩小网络中的负载平衡实现。
随着LB基于诸如例如负载增加或配置改变之类的要求而激活和停用,这些LB可更新控制器并使得该控制器对网络中的流作出改变。在示例实施例中,在不存在合适的外部控制器的情况下,LB本身可充当控制器,并可直接对网络中的流作出改变。类似地,控制器可与LB一起工作以向LB通知网络负载和其他输入、网络中的设备的健康状况等以帮助LB作出决策。
本文中公开的各实施例的技术可使用各种技术来实现。例如,本文中描述的方法可用在计算机系统上执行的软件来实现或用利用微处理器的组合或其他专门设计的专用集成电路(ASIC)、可编程逻辑器件或其各种组合的硬件来实现。具体地,本文中描述的方法可由驻留在存储介质(诸如硬盘驱动器)或计算机可读介质上的一系列计算机可执行指令来实现。应当注意,本文中公开的方法可由计算机(例如,台式机、平板计算机、膝上型计算机或服务器)、游戏控制台、手持式游戏设备、蜂窝电话、智能电话、智能电视系统等来实现。
如概述中所概括的,本公开的各实施例指的是在SDN中进行负载分发。如本文中所提及的,SDN是允许通过解耦控制平面经由较低层功能的抽象来管理网络服务的网络,该控制平面作出关于要将服务请求(例如,从客户端到服务器的话务)从数据平面发送到何处的决策,数据平面负责基于控制平面的决策将该服务请求转发至所选的目的地。数据平面可驻留在网络硬件或软件设备上,并且控制平面可通过软件来执行。由于可通过软件来执行命令或控制规则,因此SDN的平面的这种分开可允许网络虚拟化。SDN可被配置成将客户端服务请求或主机服务请求递送给虚拟机和物理设备(例如服务器)。
控制平面可被配置成例如通过实时数据网络小程序来查明与SDN和虚拟机相关联的健康状况和其他数据。控制平面可利用实时数据网络小程序和其他装置来测量虚拟机上的服务响应性,监视总连接、中央处理单元利用和存储器以及虚拟机上的网络连通性,并使用该信息来影响负载分发决策以及数据平面上的转发。
此外,控制平面可包括服务策略引擎,该服务策略引擎被配置成分析收集到的健康状况数据以及基于该分析来将该健康状况数据转换成服务策略。服务策略可包括增强(即,放大或缩小)虚拟机、话务分类引擎或后端服务器的数目的策略,补救或修复失败的虚拟机的策略,保护虚拟机的策略,引入新的虚拟机的策略,移除虚拟机的策略等等。这些服务策略可有效地影响负载平衡、高可用性以及编程SDN网络。因此,基于这些服务策略,SDN可通过周期或动态负载来放大或缩小对话务分发设备的使用,并由此分别优化各网络资源。可基于例如当天的时间来放大或缩小话务分发设备。此外,固定间隔的软件更新可导致可预测的网络拥塞,并且负载平衡可需要被放大以处理突发的拥挤现象并随后被缩小。此外,该服务的普及可使得放大该服务的需要成为必要。
SDN可包括控制器,该控制器允许对路由服务请求(诸如网络话务)进行可编程控制,而无需对网络交换机进行物理访问。换言之,控制器可被配置成跨网络来控制到服务器池或虚拟机池的话务。服务策略引擎可与控制器进行通信,并将服务策略注入到控制器中。控制器进而可根据这些服务策略来跨网络设备(诸如服务器或虚拟机)控制话务。
在一示例实施例中,SDN的服务数据平面可被配置成应用递送控制器(ADC)。控制平面可通过管理将服务请求映射到一个或多个ADC的服务策略集合来与ADC进行通信。ADC可随后通过物理或逻辑网络(即,通过服务器池或虚拟机池)将服务请求中继到后端服务器。
现参考附图,图1示出了其中可实现用于在SDN中进行负载分发的方法和系统的环境100。环境100可包括网络110、客户端120、用于负载分发的系统300、以及服务器140。客户端120可包括与网络110相关联的用户或主机。

图2是示出根据一示例实施例的用于在SDN中进行负载分发的方法200的处理流程图。方法200可由处理逻辑执行,该处理逻辑可包括硬件(例如,决策逻辑、专用逻辑、可编程逻辑和微代码)、软件(诸如在通用计算机系统或专用机器上运行的软件)或两者的组合。
方法200可始于在操作202接收与SDN相关联的网络数据。在一示例实施例中,与SDN相关联的网络数据可指示SDN的健康状况、处理单元利用率、连接总数、存储器状态、网络连通性、后端服务器容量等等。在操作204,该方法可包括检索与一个或多个服务节点相关联的服务节点数据。在一示例实施例中,一个或多个服务节点可包括虚拟机和物理设备。服务节点数据可指示节点的健康状况、动态状态、节点处理单元利用率、节点存储器状态、服务节点的网络连通性、一个或多个服务节点的响应性等等。
在操作206,可分析检索到的网络数据和服务节点数据。在操作208,可基于该分析生成服务策略。服务策略可包括以下中的一者或多者:服务地址、服务节点地址、话务分发策略、服务节点负载策略等等。该方法可进一步包括将生成的服务策略提供(即推送)给与数据网络相关联的设备。与数据网络相关联的设备可包括服务节点和话务分类引擎。
该方法200可以在操作210将生成的服务策略提供给与数据网络相关联的设备来继续。当在操作212接收一个或多个服务请求后,可在操作214根据服务策略来在一个或多个服务节点之间分发这一个或多个服务请求。在一示例实施例中,方法200可包括基于该分析来开发进一步的服务策略。进一步的服务策略可与以下相关联:放大、缩小、补救、移除与一个或多个服务节点相关联的服务,引入与一个或多个服务节点相关联的新服务,等等。
在一示例实施例中,方法200可包括由与数据网络相关联的设备来执行对后端服务器的健康检查。在进一步的示例实施例中,方法200可包括按对话务流具有最少或没有破坏的得体方式来放大或缩小服务节点、后端服务器、话务分类引擎和群集主控器。此外,可以按对话务流具有最少或没有破坏的得体方式来放大或缩小这些服务。在放大或缩小服务节点的情况下,可将服务请求重定向到一个或多个其他服务节点以继续处理与该服务请求相关联的数据。在进一步的示例实施例中,方法200可包括对从后端服务器到处理该服务的服务节点的反向话务进行优化。
图3示出了解说用于在SDN中进行服务负载分发的示例性系统300的各个模块的框图。系统300可包括适合作为群集主控器的设备群集。系统300可包括从这些设备中选取的群集主控器305。群集主控器305可被配置成跟踪SDN,并检索与SDN相关联的网络数据。在一示例实施例中,网络数据可包括以下中的一者或多者:连接总数、处理单元利用率、存储器状态、网络连通性、后端服务器容量等等。此外,群集主控器305可被配置成跟踪服务节点并检索与一个或多个服务节点相关联的服务节点数据。服务节点数据可包括以下中的一者或多者:健康状况、动态状态、一个或多个服务节点的响应性等等。换言之,群集主控器305可跟踪网络和与系统300相关联的每一个服务节点的健康状况。群集主控器305可分析检索到的网络数据和服务节点数据。基于该分析,群集主控器305可生成服务策略。服务策略可包括服务地址、服务节点地址、服务节点负载策略、话务分发策略(也被称为话务映射)等等。群集主控器305可将生成的服务策略提供给与数据网络相关联的设备(诸如服务节点和话务分类引擎)。
在一示例实施例中,群集主控器305可被进一步配置成基于该分析来开发进一步的服务策略。该进一步的策略可与以下相关联:放大、缩小、补救、移除设备(诸如服务节点、话务分类引擎、后端服务器等),引入新的服务节点、话务分类引擎、后端服务器,等等。
在一示例实施例中,群集主控器305可被进一步配置成促成针对网络管理员的应用可编程接口(未示出),以允许网络管理员基于该分析使用检索到的网络数据和服务节点数据和分析开发出进一步服务策略。该方法可允许应用开发者直接写入网络而无需管理或理解组成该网络的全部底层复杂性和子系统。
在进一步的示例实施例中,群集主控器305可包括备份单元(未示出),该备份单元被配置成在群集主控器305失败的情况下替换该群集主控器。
系统300可包括话务分类引擎310。话务分类引擎310可被实现成一个或多个软件模块、硬件模块、或硬件和软件的组合。话务分类引擎310可包括被配置成监视数据流并基于与数据流相关联的一个或多个属性(例如,统一资源定位符(URL)、IP地址、端口号等)来对数据流进行分类的引擎。得到的每一个数据流分类都可被专门设计来实现针对客户端的特定服务。在示例实施例中,群集主控器305可将服务策略发送给话务分类引擎310。话务分类引擎310可被配置成接收来自群集主控器305的服务策略。此外,话务分类引擎310可被配置成接收一个或多个传入服务请求315,例如来自路由器或交换机(未示出)的传入数据话务。通常,可将数据话务从路由器或交换机均匀地分发给每一个话务分类引擎310。在一示例实施例中,路由器可执行简单的等价多径(ECMP)路由以将话务均匀地分发给所有话务分类引擎210。话务分类引擎310可根据服务策略在一个或多个服务节点320之间分发一个或多个服务请求。可以按非对称方式将话务分发给一个或多个服务节点320。话务到服务节点320可是直接的或者通过隧道(IP中IP(IP-in-IP)或其他覆盖技术)。话务分类引擎310可以是无状态的或有状态的,可在每一分组的基础上动作,并将话务的每一分组定向到相应的服务节点320。当存在服务节点状态的改变时,群集主控器305可将新的服务策略(诸如,新的话务映射)发送给话务分类引擎310。
系统300可包括一个或多个服务节点320。此一个或多个服务节点320可包括可提供该话务被定向到的相应虚拟服务的虚拟机或物理设备。群集主控器305可将服务策略发送给服务节点320。服务节点320可被配置成从群集主控器305接收服务策略。此外,服务节点320可基于该服务策略来从话务分类引擎310接收一个或多个服务请求315。一个或多个服务节点320可根据该服务策略来处理接收到的一个或多个服务请求315。对一个或多个服务请求315的处理可包括将一个或多个服务请求315转发给一个或多个后端目的地服务器(未示出)。每一服务节点320可提供一个或多个虚拟服务。服务节点320可被配置成将服务节点数据发送给群集主控器305。
根据进一步的示例实施例,现有的服务节点可基于流到服务节点的重新分发将现有流的分组重定向到另一服务节点(如果该另一服务节点是该流的新所有者的话)。此外,对于需要使流状态受原所有者约束以维持服务持续性的情况下,接管该流的服务节点可将分组重定向到作为所考虑的流的原所有者的服务节点。
此外,在一示例实施例中,群集主控器305可对服务节点320进行周期性的健康检查,并用服务策略(诸如,话务映射)来更新这些服务节点320。当话务分配中存在改变,并且流中的数据话务的分组到达服务节点320时,服务节点320可将该分组重定向到另一服务节点。重定向可以是直接的或通过隧道(例如,IP中IP(IP-in-IP)或其他覆盖技术)。
应当注意,如果群集在网络中的每一个设备均执行后端服务器健康检查,则它可导致大量健康检查分组被发送至个体设备。鉴于此,后端服务器健康检查可由该群集中的几个设备执行,并且该结果可在该群集中的其余设备之间共享。健康检查可包括服务检查和连通性检查。服务检查可包括确定应用或后端服务器是否仍可用。如以上已经提到的,并非该群集中的每一个设备均需要执行该检查。该检查可由几个设备执行,并且结果被传播到该群集中的其余设备。连通性检查包括确定服务节点是否可到达后端服务器。到后端服务器的路径可能是服务节点专用的,因此该路径可能不能跨各服务节点分发,并且群集中的每一个设备可执行其自己的检查。
在一示例实施例中,系统300可包括组织器325。组织器325可被配置成添加和移除服务节点320、话务分类引擎310和后端服务器。组织器325可检测一个或多个服务节点320的存在,并将与一个或多个服务节点320的存在相关联的数据传送给群集主控器305。此外组织器325可向群集主控器305通知添加或移除了服务节点320。组织器325可使用一个或多个应用编程接口(API)与群集主控器305和服务节点320进行通信。
在一示例实施例中,可使用集中式或分布式网络数据库,并在系统300的群集中的所有设备(诸如群集主控器、话务分类引擎和其他服务节点)之间共享该集中式或分布式网络数据库。每一设备都可连接到网络数据库并根据其角色更新表。相关的数据库记录可被复制到作为该群集的一部分的设备。分布式网络数据库可用于存储设备的配置和状态,例如存储与群集主控器、话务分类引擎、一个或多个服务节点、后端服务器相关联的数据和服务策略数据。存储在分布式网络数据库中的数据可包括网络数据和服务节点数据。分布式网络数据库可包括具有关于服务类型、资源可用性、话务分类、网络映射等等的信息的表。群集主控器305可负责维护该分布式网络数据库,并将其复制到各设备中。网络数据库可被复制到话务分类引擎310和服务节点320。在一示例实施例中,网络数据库可跨各参与节点内部地复制数据。
在以上描述的实施例中,系统300可包括专用群集主控器305、专用话务分类引擎310和专用服务节点320。换言之,特定的设备可负责充当群集主控器、话务分类引擎和服务节点。在进一步的示例实施例中,系统300可不包括充当群集主控器的专用设备。在这种情况下,群集主控器功能可由话务分类引擎或由服务节点来提供。由此,话务分类引擎之一或服务节点之一可充当群集主控器。在充当群集主控器的话务分类引擎或服务节点失败的情况下,可将另一话务分类引擎或服务节点选为群集主控器。没有被选为群集主控器的话务分类引擎和服务节点可被配置成备份群集主控器并被与当前群集主控器同步。在一示例实施例中,群集主控器可包括多个活动的设备,这些设备通过在它们之间共享责任而可充当单个主控器。
在进一步的示例实施例中,系统300可包括专用群集主控器,而没有充当话务分类引擎的专用设备。在该情况下,话务分类可由上游的路由器或交换机之一来执行。同样,服务节点可在它们自己之间分发话务。在一示例实施例中,群集主控器和服务节点可被配置成充当话务分类引擎。
在进一步的示例实施例中,系统300可不包括充当群集主控器和话务分类引擎的专用设备。在该情况下,服务节点之一也可充当群集主控器。话务分类可由上游的路由器或交换机来完成。群集主控器可通过话务映射来对上游的路由器进行编程。此外,服务节点可在它们自己之间分发话务。
应当注意,当负载增加时添加新的服务节点并在负载变正常时移除服务节点可被得体地执行,而不会影响现有的数据话务和连接。当该服务节点出现时,话务分发可从分发给n个服务节点改变为分发给(n+1)个服务节点。
在某服务节点即将被移除时,来到该服务节点的话务可被重定向到其他服务节点。出于该目的,与即将被移除的服务节点相关联的重定向策略可由群集主控器创建,并给发送给话务分发引擎和/或服务节点。在接收到重定向策略后,话务分发引擎可将该话务定向到另一服务节点。
在一示例实施例中,系统300可包括例如多个话务分发引擎,此多个话务分发引擎中的每一个都可向多个服务提供话务。每一个话务分发引擎都可与不同的服务节点集合通信。在话务分发引擎之一失败的情况下,另一话务分发引擎可被配置成代替该失败的话务分发引擎并将失败的话务分发引擎的话务分发给相应的服务节点。因此,每一个话务分发引擎都可包括所有服务节点的地址,而不仅仅是同当前与话务分发引擎通信的服务节点相关联的地址。
图4示出用于SDN的负载分发的框图400。如所示出的,示图400包括客户端120,例如连接到网络110的计算机。网络110可包括SDN。客户端可发送对由虚拟机/服务器池405中的一个或多个服务器提供的服务的一个或多个服务请求。这些服务器可包括web服务器、无线应用服务器、交互式电视服务器等等。这些服务请求可由以上描述的用于负载分发的系统来进行负载平衡。换言之,客户端120的服务请求可在SDN的虚拟机或物理服务器池405之间智能地分发。
用于负载分发的系统可包括服务控制平面410。服务控制平面410可包括一个或多个数据网络小程序415,例如实时数据网络小程序。数据网络小程序415可检查与SDN 110和虚拟机405相关联的健康状况和其他数据。例如,数据网络小程序415可确定虚拟机405的响应性。此外,数据网络小程序415可监视总连接、中央处理单元利用率、存储器、关于虚拟机405的网络连通性等等。因此,数据网络小程序415可检索关于SDN和虚拟机服务基础结构的细粒度综合信息。
检索到的健康状况数据可被传送给服务策略引擎420。在示例实施例中,以上描述的群集主控器305可充当服务策略引擎420。服务策略引擎420可分析健康状况数据,并在该分析后,生成用于放大/缩小服务、保护服务、引入新的服务、移除服务、补救或修复失败的设备等等的服务策略集合430。用于负载分发的系统可进一步包括组织器(未示出),该组织器被配置成按需添加更多的虚拟机。因此,为了递送平滑的客户端体验,可跨虚拟机405对服务请求进行负载平衡。
此外,可将服务策略430提供给SDN控制器435。进而,SDN控制器435可跨SDN中的网络设备控制服务请求(即,数据话务)。有效地,这些策略可影响负载平衡、高可用性以及将SDN网络编程以添加或移除服务。
一般来说,通过解锁与网络、来自该网络内部的服务节点和服务器/虚拟机相关联的数据,将该数据变换成相关信息和服务策略430,并随后向用于配置SDN 110的SDN控制器435呈现这些服务策略430,所描述的基础结构可允许底层的基础结构和应用之间的反馈环以改善网络优化和应用响应性。
与控制器435和服务策略引擎420协力工作的服务控制平面410可创建多个部署可能性,其可提供基础和高级负载分发特征的阵列。具体地,为了提供简单的负载平衡功能,SDN控制器435和服务控制平面410可通过利用SDN 110的能力来提供其自身的一些负载平衡,或者替换地与ADC 440(也被称为SDN 110中包括的服务数据平面)协力工作以可任选地提供高级附加功能。
在示例实施例中,当服务控制平面410可以是单独的(即没有ADC)时,虚拟机405在被放大时可被编程有关于虚拟机405的回送接口的虚拟网络协议(VIP)地址。因此,对于需要简单服务履行的数据话务,服务控制平面410可建立用于分发服务请求的简单策略,并指令SDN控制器435将网络设备编程为将这些服务请求直接分发给不同的虚拟机/物理服务器405。该步骤可通过物理或逻辑网络执行。
在一示例实施例中,当服务控制平面410可与ADC 440协力工作以实现通常由特制的ADC设备提供的更复杂的ADC功能时,服务控制平面410可管理将服务请求映射到一个或多个ADC设备的服务策略集合。服务控制平面410可指令SDN控制器435对网络设备进行编程,使得服务请求(即话务)可到达一个或多个ADC 440。ADC 440随后可通过物理或逻辑网络将服务请求中继到后端服务器。
在所描述的实施例中,可存在若干话务流场景。在一示例实施例中,仅前向话务可行进通过ADC 440。如果需要ADC 440的简单功能(例如,速度限制、带宽限制、脚本化策略),则转发话务可穿过ADC 440。服务器上的回送接口可编程有VIP地址。来自虚拟机405的响应话务可绕开该ADC 440。
在进一步的示例实施例中,前向和反向话务可穿过ADC 440。如果需要提供更高级功能(例如,传输控制协议(TCP)流优化、安全套接字层(SSL)解密、压缩、高速缓存等)的ADC440,则服务控制平面410可能需要通过对SDN 110进行合适地编程来确保前向和反向话务两者都穿过ADC 440。
图5以计算机系统500的示例电子形式示出一机器的示意表示,在该计算机系统500内,可执行用于促使该机器执行本文中讨论的方法中的任何一者或多者的指令集。在各示例实施例中,该机器用作单独的设备或可被连接到(例如,联网到)其他设备。在联网部署中,该机器可在服务器-客户端网络环境中以服务器或客户端机器的能力操作,或者在对等(或分布式)网络环境中作为对等机操作。该机器可以是PC、平板PC、机顶盒(STB)、蜂窝电话、便携式音乐播放器(例如,诸如运动图像专家组音频层3(MP3)播放器之类的便携式硬盘驱动器音频设备)、web设备、网络路由器、交换机或桥接器、或者能够(顺序地或以其他方式)执行指定将由该机器进行的动作的指令集的任何机器。进一步,尽管仅示出了单个机器,单术语“机器”还可被认为包括任何机器的集合,其可独立地或结合地执行一组(或多组)指令来执行此处讨论的任何一个或多个方法。
示例计算机系统500包括一个处理器或多个处理器502(例如,中央处理器单元(CPU)、图形处理单元(GPU)或两者)、主存储器504和静态存储器506,它们经由总线508彼此通信。计算机系统500可进一步包括视频显示单元510(例如,液晶显示器(LCD)或阴极射线管(CRT))。计算机系统500还可包括字母数字输入设备512(例如键盘)、光标控制设备514(例如,鼠标)、盘驱动器单元516、信号发生设备518(例如,扬声器)和网络接口设备520。
盘驱动器单元516包括非瞬态计算机可读介质522,在该计算机可读介质上存储了实现本文描述的方法或功能中的任何一者或多者或被其利用的指令和数据结构(例如,指令524)的一个或多个集合。这些指令524在由计算机系统500对其进行执行期间还可完全地或至少部分地驻留在主存储器504内和/或处理器502内。主存储器504和处理器502也可构成机器可读介质。
还可利用多个公知的传输协议(例如,超文本传输协议(HTTP))中的任何一者经由网络接口设备520来通过网络526传输或接收指令524。
尽管在一示例实施例中计算机可读介质522被示为是单个介质,但术语“计算机可读介质”应当被取为包括存储一个或多个指令集的单个介质或多个介质(例如,集中式或分布式数据库和/或相关联的高速缓存和服务器)。术语“计算机可读介质”也应当被认为包括能够存储、编码或携带供该机器执行的指令集并促使该机器执行本申请的方法中的任何一者或多者,或能够存储、编码或携带被这样的指令集利用或与这样的指令集相关联的数据结构的任何介质。据此,术语“计算机可读介质”应当被认为包括但不限于固态存储器、光学和磁介质、和载波信号。这样的介质还可包括但不限于硬盘、软盘、闪存卡、数字视频盘、随机存取存储器(RAM)、只读存储器(ROM)等。
本文中描述的示例实施例可被实现在包括计算机上安装的计算机可执行指令(例如软件)的操作环境中、硬件中、或软件和硬件的组合中。计算机可执行指令可用计算机编程语言来编写,或可以用固件逻辑来具体化。如果是用符合公认标准的编程语言来编写的,则这样的指令可在各种硬件平台上并针对各种操作系统的接口来执行。虽然不限于此,但用于实现本发明方法的计算机软件程序可用任何数目的合适编程语言来编写,诸如例如,超文本标记语言(HTML)、动态HTML、可扩展标记语言(XML)、可扩展样式表语言(XSL)、文档样式语义和规范语言(DSSSL)、层级样式表(CSS)、同步多媒体集成语义(SMIL)、无线标记语言(WML)、JavaTM、JiniTM、C、C++、Perl、UNIX Shell、Visual Basic或Visual Basic脚本、虚拟现实标记语言(VRML)、ColdFusionTM或其他编译器、汇编器、解释器或其他计算机语言或平台。
因此,公开了用于在SDN中进行负载分发的方法和系统。虽然已参考特定示例实施例描述了各实施例,但显然可对这些示例实施例作出各种修改和改变,而不背离本申请较宽的精神和范围。因此,说明书和附图被认为是解说性而非限制性意义。
