图1是根据本公开一些实施例的服务调度方法的流程示意图。
在步骤102,第一VTEP接收多个VTEP的第一路由消息。这里,每个VTEP的 第一路由消息包括该VTEP连接的服务器的算力信息。
例如,算力信息可以包括算力资源的大小。算力资源例如包括中央处理器资源(CPU)、图形处理器资源(GPU)、处理器分散处理单元资源(DPU)和内存资源中的至少一种。后文将结合一些实施例进一步说明。
在一些实施例中,第一VTEP可以响应于第一路由消息和多个VTEP中的每一个建立隧道。
在步骤104,响应于客户端的服务请求,第一VTEP基于算力信息从多个VTEP中确定第二VTEP。
例如,可以基于算力资源的大小和/或服务器的服务类型确定第二VTEP,后文将结合一些实施例进一步说明。
在步骤106,第一VTEP将服务请求发送到第二VTEP,以使得第二VTEP连接的服务器为客户端提供服务。
例如,第一VTEP可以经由与第二VTEP建立的双向隧道将服务请求发送到第二VTEP,并经由双向隧道接收第二VTEP提供的服务。后文将结合一些实施例进一步说明。
上述实施例中,第一VTEP和多个VTEP之间通过路由信息实现算力信息端到端的传递,进而由第一VTEP基于算力信息确定为客户端提供服务的服务器连接的第二VTEP。由于服务器的算力可以影响服务质量,在服务调度时基于算力信息确定第二VTEP,可以使得合适的服务器为客户端提供服务,有利于提高服务质量。
下面结合一些实施例对第一VTEP如何接收多个VTEP的第一路由消息进行介绍。
在一些实施例中,多个VTEP中的每个VTEP接收与该VTEP连接的服务器发送的算力信息,再基于算力信息生成第一路由消息。
作为一些实现方式,多个VTEP中的每个VTEP可以连接一个或多个服务器。在一个VTEP连接多个服务器的情况下,第一路由消息例如还可以包括多个服务器的标识。
在一些实施例中,第一VTEP基于边界网关协议(BGP)接收多个VTEP的发送的第一路由消息。
表1是根据本公开一些实施例的第一路由消息。
表1
表1所示的实施例中,算力资源包括CPU、GPU、DPU和内存资源。
下面结合一些实施例介绍第一VTEP如何基于算力信息从多个VTEP中确定第二VTEP。
在一些实施例中,算力信息包括算力资源的大小。这种情况下,第一VTEP基于算力信息,确定算力资源的大小大于预设值的一组服务器,将多个VTEP中与一组服务器中的一个服务器连接的VTEP确定为第二VTEP。
例如,在算力信息包括CPU算力信息的情况下,确定CPU算力大于预设值的一组服务器,选择这一组服务器中的一个作为为客户端提供服务的服务器,将与该服务器连接的VTEP确定为第二VTEP。
又例如,服务请求还可以包括客户端需要的算力资源的种类(例如客户端需要CPU算力资源),在算力信息包括CPU算力信息、GPU算力信息和DPU算力信息的情况下,第一VTEP确定CPU算力大于预设值的一组服务器,选择这一组服务器中的一个作为为客户端提供服务的服务器,将与该服务器连接的VTEP确定为第二VTEP。
在一些实施例中,算力信息还包括算力资源的算力类型,服务请求携带客户端需要的多种算力类型。这种情况下,一组服务器中每个服务器的算力资源的大小为多种算力类型的算力资源的加权计算结果。
例如,在算力信息包括CPU、GPU和DPU这三种算力类型,服务请求携带的客户端需要的多种算力类型为CPU和GPU的情况下,第一VTEP可以对CPU和GPU这两种算力类型的算力资源进行加权计算得到加权计算结果,确定加权计算结果大于预设值的一组服务器,选择这一组服务器中的一个作为为客户端提供服务的服务器,将与该服务器连接的VTEP确定为第二VTEP。
在一些实施例中,服务请求携带加权信息,加权信息包括多种算力类型中每种算力类型的权重,加权计算结果基于加权信息计算得到。
例如,服务请求携带CPU和GPU的权重,第一VTEP可以基于权重对CPU和GPU这两种算力类型的算力资源进行加权计算得到加权计算结果。
应理解,以上预设值可以是固定的某个值,也可以是某个算力资源的大小。例如,一共有按照算力资源从小到大的顺序从1至10依次排列的10个服务器,预设值可以是第8个的服务器的算力资源的大小。这种情况下,第9个服务器和第10个服务器即为第一VTEP确定的一组服务器。
上述实施例中,通过设置预设值对服务器进行筛选从而确定第二VTEP,有利于确保为客户端提供服务的服务器的算力能够满足要求,从而提高服务质量。
进一步地,上述实施例提供了多种方法来确定提供服务的服务器,有利于充分满足客户端的需求。
在一些实施例中,第二VTEP连接的服务器为一组服务器中算力资源最大的服务器。
例如,在算力信息包括CPU算力信息的情况下,确定CPU算力最大的服务器作为为客户端提供服务的服务器,将与该服务器连接的VTEP确定为第二VTEP。
上述实施例中,通过选择算力最大的服务器来提供服务,有利于进一步提高服务质量。
在一些实施例中,算力信息除了包括算力资源的大小,还包括一种或多种第一服务类型。这里,服务请求携带客户端需要的第二服务类型,第二VTEP连接的服务器的一种第一服务类型与第二服务类型相同。
作为一些实现方式,服务类型可以包括网页浏览、视频播放以及音乐播放等,第一服务类型也即服务器能够提供的服务类型,第二服务类型也即客户端需要的服务类型。
例如,服务器A的第一服务类型包括网页浏览,服务器B的第一服务类型包括视频播放和音乐播放,客户端C的第二服务类型是视频播放,则服务器B的一种第一服务类型与第二服务类型相同。进一步地,如果服务器B的算力资源的大小大于预设值,例如服务器B的算力资源是最大的,可以确定服务器B作为为客户端提供服务的服务器,将与服务器B连接的VTEP确定为第二VTEP。
上述实施例中,从算力资源的大小和服务类型两方面对服务器进行选择,既保证了服务器能够提供客户端所需的服务,又有利于提高为客户端提供的服务质量。
下面结合一些实施例介绍第一VTEP如何将服务请求发送到第二VTEP,以使得第二VTEP连接的服务器为客户端提供服务。
图2是根据本公开另一些实施例的服务调度方法的流程示意图。
在步骤202,第一VTEP经由第一隧道将服务请求发送到第二VTEP。这里,第一隧道由第一VTEP基于第一路由消息建立。
在步骤204,第一VTEP经由第二隧道接收第二VTEP发送的服务响应。这里, 第二隧道由第二VTEP基于第一VTEP发送的第二路由消息建立,服务响应由第二VTEP连接的服务器生成。
上述实施例中,基于第一隧道和第二隧道组成的双向隧道传递服务请求和服务响应,无须感知服务器和客户端之间的中间物理链路,有利于提高大型数据中心场景下的服务质量。
在一些实施例中,第二路由消息由第一VTEP响应于服务请求生成。
例如,第一VTEP接收到客户端发送的服务请求后,基于服务请求携带的客户端的IP地址生成第二路由消息。
在一些实施例中,第二路由消息为MAC地址通告消息或IP Prefix通告消息。
下面结合一个具体的实施例介绍如何建立双向隧道(也即第一隧道和第二隧道)。
图3是根据本公开一些实施例的建立双向隧道的流程示意图。简洁起见,图3中只示出了第二VTEP,应理解,多个VTEP中的每个都可以采用与图3所示的第二VTEP类似的方式与第一VTEP建立双向隧道。
在步骤302,服务器发送算力信息到第二VTEP。算力信息例如可以包括CPU、GPU、DPU和内存资源这四种算力资源的大小。
在步骤304,第二VTEP基于算力信息生成第一路由消息。这里,第一路由消息包括算力信息。第一路由消息例如是表1所述的第一路由消息。
在步骤306,第二VTEP发送第一路由消息到第一VTEP。例如,可以基于BGP协议发送第一路由消息。
在步骤308,第一VTEP基于第一路由消息建立第一隧道。由此,第一VTEP可以经由第一隧道向第二VTEP传递数据,例如服务请求。
在步骤310,第一VTEP接收客户端发送的服务请求。这里,服务请求可以携带客户端的IP地址。
在步骤312,第一VTEP基于客户端的IP地址生成第二路由消息。例如,第二路由消息可以是MAC地址通告消息或者IP Prefix通告消息。
在步骤314,第一VTEP发送第二路由消息到第二VTEP。
在步骤316,第二VTEP基于第二路由消息建立第二隧道。由此,第二VTEP可以经由第二隧道向第一VTEP传递数据,例如服务响应。上述实施例中,利用第一路由消息传递算力信息,使得第一VTEP能够及时地获取算力信息,进一步地,通过建立双向隧道,有利于提高大型数据中心场景下的服务质量。
本说明书中各个实施例均采用递进的方式描述,每个实施例重点说明的都是与其它实施例的不同之处,各个实施例之间相同或相似的部分相互参见即可。对于VTEP实施例而言,由于其与方法实施例基本对应,所以描述的比较简单,相关之处参见方法实施例的部分说明即可。
