Description

基于动态服务响应时间向服务器分配流量的系统和方法
技术领域
本发明总的来说涉及数据通信,更具体地,涉及基于服务处理参数将应用程序流量分配给服务器的方法和系统。
背景技术
web服务和云计算正以前所未有的速度部署。每天在数据中心卸载和安装新服务器。web服务和企业计算的需要来自四面八方。面向消费者的服务包括:智能手机应用程序、诸如基于位置的服务移动电话应用程序、逐向导航服务、诸如KindleTM的电子书服务、诸如YouTubeTM或者HuluTM的视频应用程序、诸如PandoraTM或者iTunesTM的音乐应用程序、诸如NetflixTM的互联网电视服务以及许多其他快速增长的消费者web服务。在企业方面,面向消费者的服务包括:诸如GoogleTM文档、MicrosoftTM Office Live和SharepointTM软件的基于云计算的服务、Salesforce.comTM的在线软件服务、远程出席和web会议服务以及许多其他企业云计算服务。
因此,部署越来越多的服务器以适应日益增长的计算需求。传统上,这些服务器由诸如应用交换控制器或者服务器负载均衡器(ADC/SLB)的服务网关管理,该服务网关通常为在固定模块中或者在机箱中的网络设备,或者运行在同质化服务器ADC/SLB中基于进入服务请求管理服务器的应用程序流量的软件模块。在服务器之间分配流量的常用方法是基于应用程序(HTTP、FTP、HTTPS等)、诸如URL的服务地址、基于网络接口或者主机IP地址的优先级分配服务请求。在假设服务器完全用来处理服务请求的情况下,ADC/SLB可将服务请求分配给服务器。通常,满载服务器不会很好地处理服务请求。事实上,当服务器为忙时,大部分服务请求遭受到延迟或者没有服务可用。通常较佳做法是不将服务请求进一步分配给忙服务器。当前ADC/SLB允许网络管理员设定最大服务会话容量,使得ADC/SLB不发送超过最大容量的服务请求给该服务器。然而,对服务器的静态配置限制不能充分利用服务器的容量,并且并不是所有服务请求都从服务器要求相同处理。有利的是,ADC/SLB基于来自服务器的服务响应时间判定服务器是否为忙,使得ADC/SLB可减少发送更多服务请求给服务器。
因此,需要一种基于动态服务响应时间保护服务器过载的ADC/SLB的系统和方法。

图1示出服务网关110与服务器200之间的服务会话321。该服务网关110从主机100接收服务请求301。该服务请求301通过数据网络153交换。在一个实施方式中,服务请求301为诸如HTTP(超文本传输协议)请求的web服务请求、安全HTTP请求、FTP(文件传输协议)请求、文件传输请求、SIP(会话初始化协议)会话请求、基于web技术的请求、视频或者音频串流请求、web会议会话请求、或者通过互联网或者企业网络的任何请求。
主机100为具有网络存取能力的计算器件。该主机100在操作上耦合至处理器103和计算机可读介质104。该计算机可读介质104存储计算机可读程序码以实施如本文所述本发明的各种实施方式。在一个实施方式中,主机100为工作站、桌上型个人计算机或者膝上型个人计算机。在一个实施方式中,主机100为个人数据助理(PDA)、智能手机或者移动电话。在一个实施方式中,主机100为机顶盒、互联网媒体查看器、互联网媒体播放器、智能传感器、智能医疗器件、机顶盒、网络电视机、网络DVR、网络蓝光播放器或者媒体中心。
在一个实施方式中,数据网络153为互联网协议(IP)网络。在一个实施方式中,数据网络153为企业数据网络或者区域企业数据网络。在一个实施方式中,数据网络153为互联网服务提供商网络。在一个实施方式中,数据网络153为常驻数据网络。在一个实施方式中,数据网络153包括诸如以太网的有线网络。在一个实施方式中,数据网络153包括诸如WiFi网络或者蜂窝式网络的无线网络,。
服务网关110操作上耦合至处理器113和计算机可读介质114。该计算机可读介质114存储计算机可读程序码,该计算机可读程序码当由处理器113执行时,实施如本文所述本发明的各种实施方式。在一些实施方式中,服务网关110实施为服务器负载均衡器、应用交换控制器、服务交换平台、流量管理器、安全网关、防火墙系统的组件、虚拟专用网络(VPN)的组件、用于视频服务器的负载均衡器、或者用于将负载分配给多个服务器的网关。
服务器200操作上耦合至处理器213和计算机可读介质214。该计算机可读介质214存储计算机可读程序码,该计算机可读程序码当由处理器213执行时,实施如本文所述本发明的各种实施方式。在一些实施方式中,该计算机可读程序码将服务器200实施为web服务器、文件服务器、视频服务器、数据库服务器、应用程序服务器、语音系统、会议服务器、媒体网关、SIP服务器、远端存取服务器、VPN服务器或者媒体中心。
服务网关110经由数据网络155连接至服务器200。在一个实施方式中,数据网络155与数据网络153相同。在一个实施方式中,数据网络155与数据网络153不同。在一个实施方式中,主机100不直接存取数据网络155。在一个实施方式中,主机100直接存取数据网络155。
图2和图7示出由服务网关110处理服务请求301的方法的实施方式。在一个实施方式中,服务网关110从主机100接收服务请求301,并且通过建立服务网关110与服务器200之间的服务会话321来将服务请求301转送到服务器200(701)。服务网关110判定服务会话321的服务请求时间361(702)。在一个实施方式中,服务请求时间361为诸如一天时间、系统时间、时间计数器的时间戳。在一个实施方式中,服务请求时间361为服务网关110将服务请求301发送至服务器200的时间。在一个实施方式中,服务请求时间361为服务网关110从服务器200接收“接收服务请求301”确认的时间。
在服务器200处理服务请求301之后,服务器200利用服务响应352来响应。在一个实施方式中,服务响应352包括web页、文档、文件、图片、音频或者视频串流信号或者语音电话。在一个实施方式中,服务响应352包括错误指示354。错误指示354可包括HTTP错误状态码、FTP错误码、SIP错误信息或者任何其他错误码。
服务网关110接收服务响应352,并且将服务响应352转送到主机100(703)。服务网关110在接收服务响应352之后立即判定服务响应时间362(704)。在一个实施方式中,服务响应时间362为诸如一天时间、系统时间、时间计数器的时间戳,并且与服务请求时间361兼容。在一个实施方式中,服务响应时间362为服务网关110接收服务响应352的时间。在一个实施方式中,服务响应时间362为服务网关110接收服务响应352的第一条信息的时间。在一个实施方式中,服务响应时间362为服务网关110接收服务响应352的最后一条信息的时间。在一个实施方式中,服务响应时间362为服务网关110与服务器200断开服务会话321的时间。在一个实施方式中,服务响应时间362包括在服务响应352中。
在判定服务请求时间361和服务响应时间362之后,服务网关110从服务请求时间和服务响应时间计算服务请求301的服务处理时间360(705)。服务处理时间360通常测量服务请求时间361与服务响应时间362之间的持续时间。在一实例中,服务网关110从服务响应时间362减去服务请求时间361以获得服务处理时间360。在另一实例中,服务网关110计算服务请求时间361与服务响应时间362之间的持续时间以判定服务处理时间。例如,服务处理时间360为10毫秒、5毫秒、247毫秒、3秒、15秒、1分钟、75微秒或者289个单位时间。
在一个实施方式中,服务网关110在计算服务处理时间360之前验证服务响应352。在一实例中,如果服务响应352含有错误指示354,那么服务网关110验证服务响应352。在一个实施方式中,如果存在错误指示354中所指示的错误,那么服务网关110不计算服务请求301的服务处理时间360。
在一个实施方式中,服务网关110包括完成服务会话计数器326,其将服务网关110与服务器200之间的完成服务会话数目计数。在一个实施方式中,在服务网关110接收服务响应352之后或者在服务网关110与服务器200断开服务会话321之后,服务网关110将完成服务会话计数器326递增1。在一个实施方式中,服务网关110在判定服务处理时间360之后将完成服务会话计数器326递增1。
图3示出判定服务器200是否为忙的方法的实施方式。服务网关110包括服务器200的服务器示忙器378,指示服务器200是否为忙。在一个实施方式中,服务器示忙器378的值0或者“不忙”指示服务器200不忙,而值1或者“忙”指示服务器200忙。服务网关110基于服务处理时间360更新服务器示忙器378。
在一个实施方式中,服务网关110包括预期服务处理时间374。参见图3和图7两者,服务网关110比较服务处理时间360与预期服务处理时间374(706)。响应于判定该服务处理时间超过预期服务处理时间374,服务网关110将服务器示忙器378更新为“忙”(708)。
在一个实施方式中,服务处理时间360需要至少比预期服务处理时间374大50%,以超过预期服务处理时间374。在一个实施方式中,服务处理时间360需要至少比预期服务处理时间374大300%。在一个实施方式中,服务处理时间360需要比预期服务处理时间374更大。
在一个实施方式中,服务网关110判定服务处理时间360不超过预期服务处理时间374(707),以及作为回应,服务网关110将服务器示忙器378更新为“不忙”(709)。
在一个实施方式中,预期服务处理时间374是基于服务请求301。在一个实施方式中,服务请求301包括服务请求统一资源定位器(URL)。在一个实施方式中,根据服务属性379配置预期服务处理时间374。该服务属性379为影响预期服务处理时间374的属性。例如,不同协议将以不同速率处理服务请求,以及因此将具有不同预期服务处理时间。在一个实施方式中,服务属性379是基于服务请求URL。在一个实施方式中,服务属性379是基于服务请求URL的一部分,诸如域名、web站点中的web文件夹名、文档类型、服务请求URL中所指示的协议。例如,服务请求URL为“http://www.abc.com/shops/shoe.html”。服务属性379是基于域名“www.abc.com”、web文件夹“www.abc.com/shops”、文档类型.html(或者其他文档类型,诸如.php、.asp等)、协议http(或者其他协议,诸如ftp、https、sip等)。在一个实施方式中,服务属性379与服务器200上所实施的程序码有关。例如,服务器200为使用Apache web服务器软件、Microsoft web服务器软件、Oracle web服务器软件或者其他web服务器软件的web服务器。服务属性379与web服务器软件有关。
在一个实施方式中,服务属性379是基于域名“www.a10networks.com”,以及预期服务处理时间374为10毫秒。在一个实施方式中,服务属性379是基于HTTP协议,以及预期服务处理时间374为75毫秒。在一个实施方式中,服务属性379是基于FTP文件下载协议,以及预期服务处理时间374为2分钟。在一个实施方式中,服务属性379是基于HTML文档类型,以及预期服务处理时间374为20毫秒。
在一个实施方式中,服务属性379与服务器200上所实施的程序码有关。在一个实施方式中,服务器200使用Apache web服务器软件,以及预期处理时间为50毫秒。服务器200使用Microsoft web服务器软件,以及预期处理时间为90毫秒。
在一个实施方式中,服务属性379与以上描述所提到的多个属性有关。预期处理时间可通过将该多个属性的多个预期处理时间求和来判定。
在一个实施方式中,服务网关110包括数据存储器380,其存储预期服务处理时间374和相关联服务属性379。在一个实施方式中,服务网关110比较服务请求301或者服务器200与数据存储器380中的服务属性379。如果存在匹配,那么服务网关110检索与匹配服务属性379相关联的预期服务处理时间374,并且比较检索的预期服务处理时间374与该服务处理时间360。在一个实施方式中,预期服务处理时间374与任何服务属性无关。服务网关110检索预期服务处理时间374,并且将其与服务处理时间360比较。
在一个实施方式中,由使用者配置预期服务处理时间374。
在一个实施方式中,基于先前服务会话的服务处理时间自动判定预期服务处理时间374。在判定服务处理时间360之后,服务网关110立即通过以下公式计算调整预期服务处理时间376:
在所述实施方式中,服务网关110在改变完成服务会话计数器325之前,计算调整预期服务处理时间376。在一个实施方式中,如果服务处理时间360超过预期服务处理时间374,或者如果服务响应352包括错误指示354,那么服务网关110不调整预期服务处理时间374。在该实施方式中,服务网关110不改变完成服务会话计数器326。
在一个实施方式中,预期服务处理时间374与服务属性379相关联。完成服务会话计数器326也与服务属性379相关联以对各个服务属性实施分开计数。服务网关110在计算调整预期服务处理时间376之前检查服务请求301或者服务器200是否匹配服务属性379。
在一个实施方式中,服务网关110利用调整预期服务处理时间376替代预期服务处理时间374。所述调整预期服务处理时间376变为服务网关110与服务器200之间的下个服务会话的预期服务处理时间374。
在服务网关110更新服务器忙指示之后,服务网关110从主机(71)接收下个服务请求,并且所述方法重复。
图4和图8示出基于服务器示忙器378处理服务请求301的方法的实施方式。在一个实施方式中,服务网关110包括服务请求缓冲器331。在一个实施方式中,服务网关110从主机110接收服务请求301(801)。在一个实施方式中,服务网关110将服务请求301放入服务请求缓冲器331中。在另一个实施方式中,服务网关110检查服务器示忙器378(802)。当服务器示忙器378指示服务器200为“忙”时(803),服务网关110将服务请求301放置到服务请求缓冲器331中(804)。在一个实施方式中,当服务器示忙器378指示服务器200为“不忙”时(803),服务网关110将服务请求301转送到服务器200(701),如上文图2和图7所述。在另一个实施方式中,当服务器示忙器378指示服务器200为“不忙”时,服务网关110检查服务请求缓冲器331是否为空(805)。如果服务请求缓冲器331为空,那么服务网关110将服务请求301转送到服务器200(701)。如果服务请求缓冲器331不为空,那么服务网关110将服务请求301放置到服务请求缓冲器331中(806)。该服务网关110然后将服务请求缓冲器331中的各个服务请求转送到服务器200(701),直到服务请求缓冲器331为空,或者直到服务器示忙器378被改为“忙”。
图5示出在服务网关110更新服务器示忙器378之后处理服务请求的方法的实施方式。服务网关110根据服务器示忙器378的不同值处理服务请求缓冲器331中的服务请求301。在一个实施方式中,服务器示忙器378具有更新值“不忙”。服务网关110检验服务请求缓冲器331,并且找到服务请求301。服务网关110将服务请求301转送到服务器200(701)。
在一个实施方式中,服务器示忙器378具有更新值“忙”。在一个实施方式中,服务网关110不立即处理服务请求缓冲器331。服务网关110包括计时器119。当计时器119过期时,服务网关110找到服务请求缓冲器331中的服务请求301,并且将服务请求缓冲器331中的服务请求301转送到服务器200(701)。计时器119可被配置为例如1分钟、30秒、1秒、400毫秒、5毫秒、300微秒的持续时间或者任何其他持续时间,使得服务不会受到服务请求301严重影响。在一个实施方式中,持续时间是基于服务请求301的属性。
图6示出基于服务优先级处理服务请求的方法的实施方式。在一个实施方式中,服务请求303与服务优先级403相关联。在一种情况下,服务优先级403是基于服务请求303URL。在一种情况下,服务优先级403是基于主机100,诸如主机100IP地址、主机100使用者身份。在一种情况下,服务优先级403与网络接口相关联,服务网关110从该网络接口接收服务请求303。服务网关110判定服务请求303的服务优先级403。
服务请求缓冲器331被配置为存储具有服务优先级401的服务请求。
在服务器示忙器378具有更新值“忙”的实施方式中,服务网关110比较服务优先级403与服务优先级401。响应于找到匹配,服务网关110将服务请求303放置到服务请求缓冲器331中。
在一个实施方式中,服务网关110包括第二服务请求缓冲器332。服务请求缓冲器332被配置为存储具有服务优先级402的服务请求,服务优先级402高于服务优先级401。
在服务器示忙器378具有更新值“不忙”的实施方式中,服务网关110处理服务请求缓冲器332中的服务请求,先于处理服务请求缓冲器331中的服务请求。在一个实施方式中,服务网关110在将服务请求缓冲器331中的服务请求301发送给服务器220之前将服务请求缓冲器332中的服务请求302发送给服务器200。
在一个实施方式中,服务网关110在处理服务请求缓冲器331之前处理来自服务请求缓冲器332的所有服务请求。在一个实施方式中,服务网关110包括服务比率117,其中,服务网关110根据比率117处理服务请求缓冲器332和服务请求缓冲器331,其中,服务比率117相较于较低优先级服务请求缓冲器331更偏爱高优先级服务请求缓冲器332,以避免缺少服务请求缓冲器331中的较低优先级服务请求。
虽然根据所示实施方式已经描述本发明,但是本领域的普通技术人员应理解,可对这些实施方式进行更改,并且更改在本发明的精神和范围内。因此,在不背离所附权利要求的精神和范围的情况下,本领域的普通技术人员可进行各种更改。
