Description

自动装置配置
【0001】本申请要求享有申请号为60/776,796,申请日为2006年2月27日的临时申请的申请日期优先权,此处引用其全部说明书。
技术领域
【0002】本公开的发明总体上涉及用于在网络上一组装置之间发送和接收数据的系统和方法。所选的实施例总体上涉及针对IP语音通信(VoIP)网络在可配置装置和维护系统之间发送和接收数据。
背景技术
【0003】通常,在因特网上发送语音信号的系统通常包括一个用于把模拟语音信号转换成数字信号并且发送此数字信号的可配置装置。通常这些装置被连接到传统电话或与电话集成来提供给客户传统和熟悉的电话功能。
【0004】由于如VoIP等的数字语音网络变得越来越复杂,部署的装置要补充管理系统来维护和控制装置功能的各个方面。这些管理系统有时配置装置来控制它们的运行并且允许客户访问某些与服务有关的配置参数。为确保装置的正常运行,装置优先用最当前的配置运行。这些配置通常是基于简档的,这些简档包括控制装置的特征,性能和整体表现的各个方面的参数。
【0005】图1示出一个现有技术系统100的运行和用于在可配置装置101和管理系统105之间传输数据的方法。响应某些内部的事件或变化,SIP代理服务器103在网络上发送一个作为轮询请求111的SIP NOTIFY信息到可配置装置101。作为替代,轮询请求采取定时事件113的形式。定时事件在可配置装置101处本地生成或由远程定时器生成。一旦接收到轮询请求,装置101通过发送一个HTTP GET请求到管理系统105来轮询管理系统105。这个请求检查并且尝试接收对于可配置装置101而言最近的配置文件。或者,装置101可以等候预定数目的轮询请求或检测在轮询请求中的一个特别信息以触发它轮询管理系统105。一旦接收到HTTP GET或相似的信息,管理系统105以HTTP协议响应117传输一个新的配置文件151到装置101(如果可用的话),以进行响应。可配置装置101、SIP代理服务器103和管理系统105之间的通信通常发生在因特网或连接通信实体的其他可用网络上。
【0006】有时候,可配置装置101利用一个HTTP POST或PUT操作119传输文件153到管理系统105。在HTTP POST或PUT操作119中的文件包括多种由装置产生的文件类型,如装置日志信息。一旦接收到文件153,管理系统105发送一个确认信息121到可配置装置101,确认文件已被接收,从而结束HTTP POST/PUT操作。
【0007】传统的在装置101和管理系统105之间进行数据传输的系统和方法的缺点是需要在通信实体之间建立许多独立的通信会话。这些众多的会话消耗带宽和硬件资源。为了有效地调整它们的VoIP和数据网络,网络管理员和服务提供商都面临用易于管理的和最小的投入在共享基础设施中维护不同的远程部署的装置的性能和功能的挑战。
【0008】因此,在工业中需要提供一种在可配置装置和管理系统间传输数据的更有效的系统和方法的技术解决方案
发明内容
【0009】各种公开的实施例总体上涉及用于管理在可配置装置和管理系统间的数据传输的系统和方法,包括产生装置数据,检测轮询请求,响应轮询请求在第一公用通信会话中发送装置数据的至少一部分和配置请求,并接收对应于该配置请求的配置文件。
附图说明
【0010】本公开的发明的各方面参考以下的详细描述和所附的示例性非限制性实施例,对本领域技术人员来说将是或变得更为清楚:
【0011】图1示出一个用于在可配置装置和管理系统间传输数据的现有技术系统和方法;
【0012】图2是一个对示例性公开方法进行概述的流程图;
【0013】图3是一个在可配置装置和管理系统之间传输数据的示例性实施例的示意图;和
【0014】图4是一个示例性可配置装置的示意图。
具体实施方式
【0015】本公开发明的一个方面包括在公用通信会话中对数据传输进行分组。另一个方面包括为成组传输或单个传输在远程可配置装置中收集的数据确定优先次序。还有一个方面包括基于由所收集的装置数据反映的装置状况选择一个配置文件来更新远程可配置装置。
【0016】各个公开实施例有利地为在可配置装置和管理系统间传输数据提供了更有效的系统和方法。尤其是,所选的实施例减少了所要求的联网的实体之间所需的通信会话的数量。
【0017】图2示出对示例性公开方法进行概述的流程图。该方法包括产生装置数据S201,检测轮询请求S203,响应轮询请求在第一公用通信会话中发送装置数据的至少一部分和配置请求S205,并接收对应于该配置请求的配置文件S207。装置数据最好由经由网络可操作地连接到管理系统的远程可配置装置产生。装置数据最好由远程可配置装置本地存储。尽管如此,如其他地方所讨论的,装置数据的一部分最好被存储用于周期性传输,而另一部分一产生就被发送了。
【0018】装置数据包括但不限于装置状态条目、装置错误条目、通信错误条目、装置性能条目和通信性能条目。例如,装置状况条目表明装置的运行状况,如“可运行”、“故障”或“忙”,并且可选地表明当前该装置所使用的配置简档版本。在另一个例子中,装置错误条目表明与装置本身相关的一种类型的错误,如发生故障的部件或软件模块。在另一个例子中,通信错误条目表明该装置的网络连接有问题,如低带宽或连接断开。在另一个例子中,装置性能条目表明装置功能的度量,如运行时间或时段、数模或模数转换规格、采样速率和丢失的帧或数据包。在另一个例子中,通信性能条目表明装置的通信功能的度量,如数据传输速率、延迟或信号噪声。
【0019】最好为装置数据确定优先次序以识别至少低优先级项。低优先级项包括但不限于不反映装置或网络性能立即或紧急故障或严重问题的数据条目。在轮询请求被检测到后低优先级项最好随配置请求一起被存储和发送。在替代实施例中,所有的装置数据,包括高优先级或重要装置数据,一旦检测到轮询请求就随配置请求一起被存储和发送。
【0020】轮询请求包括但不限于来自SIP代理服务器的SIPNOTIFY信息。或者,轮询请求从管理系统被接收。或者,轮询请求在本地产生。比如,装置可选地对外部轮询请求进行计数并且在预定数目的轮询请求之后开始传输。或者,装置间歇地或周期性地基于内部定时器发送。可选地,独立的本地定时器和外部接收到的请求一起运行。因此,装置依照常规进度表和依照所产生的外部轮询请求更新,例如当一个服务提供商试图响应网络性能或网络安全状况执行一个网络范围的变化时。
【0021】配置请求包括但不限于对最近的配置文件的请求。或者,例如当远程的可配置装置正试图在关键故障后恢复时,所述请求可能是要求原始配置文件或者针对检测到的关键故障的补丁。
【0022】配置文件包括但不限于改变可配置装置的性态或能力的固件更新、软件补丁或更新后的特征参数值。
【0023】配置文件请求和装置数据单独地或结合地被管理系统用来选择传输到可配置装置的配置文件。另外,考虑到和配置请求一起接收的装置数据,管理系统还可选地分析由该装置先前发送的数据(例如一旦产生就被发送的高优先级或关键装置数据项)。分析这些来自装置的数据类型使管理系统能够确定可配置装置是需要更新其配置的大部分还是少部分。例如,可配置装置如果被损坏的话,可能请求配置文件的错误版本并且表现出低或不令人满意的性能。如果关键错误和问题取决于先前发送的关键数据,则管理系统鉴于它对装置数据的分析可选地选择并且发送与所请求的配置文件不同的配置文件。另外,如完全固件升级或用户指南文档等的附加文件可选地基于检测到的可配置装置的问题而被发送。
【0024】图3是用于在改进了的可配置装置301和改进了的管理系统305之间传输数据的示例性实施例的示意图。
【0025】可配置装置301产生装置数据包括但不仅限于装置状态条目、装置错误条目、通信错误条目、装置性能条目和通信性能条目,如其他地方公开的一样。可选地,装置数据被存储并被确定优先次序以识别低优先级项381和较高优先级或关键项383。
【0026】轮询请求在可配置装置301处被接收。优选的是,SIP代理服务器303在网络上发送一个作为SIP NOTIFY信息311的轮询请求到可配置装置301。轮询请求可选地是一个从本地源到可配置装置301的定时事件313。或者,轮询请求321被可选地从管理系统305接收。在某种体系结构中(例如,如果可配置装置301置于网络地址翻译(NAT)路由器或防火墙之后)管理系统305和SIP代理服务器303通信323使管理系统305确定网络身份或可配置装置301的位置。
【0027】一旦检测到轮询请求311/313,装置301通过发送装置数据和配置请求做出响应。在第一公用通信会话中,装置301最好通过随请求最近的配置文件的请求317一起将一个包含文件351的HTTP POST或PUT信息315发送到管理系统305,从而做出响应。与HTTP POST或PUT消息315一起发送的文件351包括但不限于如其他地方公开的装置数据。这些文件或其分析根据装置301的状态更新管理系统305。另外,文件可选地辅助识别装置301或通信到和通信自装置301的问题(现存的或潜在的)。在这个通信会话期间,补充文件355也被可选地发送到管理系统305。在一个实施例中,在这个操作期间发送的数据包括诊断和调试数据,例如否则将被存储在日志文件中或利用如“系统日志(syslog)”这样的网络协议被一次一行发送的调试信息。除此之外,数据可以包括和装置执行的应用程序或功能有关的性能相关数据。例如,对于VoIP装置来说,它可能包括在一些最近进行的通话中被动地被测量的声音质量信息。数据还可以包括其他随主要功能执行的“主动”测量,如测量网络连通性,作为应用程序一部分探测网络上流量的流通路径,并且把结果返回给管理系统。在替代实施例中,采用其它协议来传输数据,包括但不限于文件传输协议(FTP)、SSH FTP(SFTP)、经由SSL的FTP(FTPS)、或普通文件传输协议(TFTP)。
【0028】在文件351被发送到管理系统305以后,如果需要的话,管理系统发送回装置一个新的配置文件353。新的配置文件353由管理系统305依照所分析的装置状况选择。各种确定或估计装置状况的方法在其他地方有所描述。
【0029】管理305系统可选地保持数据库391中与装置301的状态相应的记录,以辅助对适当配置文件353的选择。这些记录可选地对应于反映在装置301发送的装置数据中的装置301的历史或当前的状态或状况。另外,数据库391还可选地包括对应于各种类型装置301和装置状况/状态的多个配置文件。数据库391如现有技术中已知的那样由任意数量的单个或集成的存储器实体实现。
【0030】在这个通信会话中的配置文件353的传输有利地消除了可配置装置301和管理系统305之间的单独和独立的TCP连接和其他事务的需要。这种耦合传输也避免了建立额外的通信会话的相关开销和延迟。配置文件353的传送还用于对已经接收到文件351(如装置数据)做出肯定确认319。
【0031】在另一个实施例中,响应于最好同HTTP POST或PUT操作一起传输的文件351的接收,管理系统305在第二通信会话中把另一种类型的文件357和配置文件353发送回装置301。这个补充的文件357包括但不限于固件补丁、更新后的故障检修指南或软件或广告。因此,通过对随配置请求一起的偶然产生的数据和按照常规传输的数据进行分组,实现了更有效的可配置装置和管理系统间数据传输的管理。
【0032】图4是一个示例性可配置装置401的示意图。装置401可以被用来辅助上述的数据传输方法。装置401可以是用于访问如企业内部网,因特网或与之相似的基于IP的网络的任意形式的通用计算机处理器。装置401包括中央处理单元(CPU)407、存储器403、和CPU 407的支持电路409。装置401还包括用于将装置401连接到客户设备(未示出)和服务提供商代理设备的端口411/413和一个或多个用来访问装置401和/或执行与装置401相关的辅助或管理功能的输入/输出装置(未示出)。需要注意的是,在图4中端口411/413被表示为分开的总线结构;尽管如此,它们也可以作为替代地成为单独总线结构,基本上不会使装置401或本发明的预期操作性能恶化或改变。除此之外,以下详细描述的装置401和它的运行部件和程序设计被示为一个单个的实体;尽管如此,该装置也可以是一个或多个散布在系统内的装置和编程模块,每个执行上述诊断分析的一个特殊或专门的部分。装置401可选地包括显示器或与显示器通信,用于将可视信息传送到客户。通过非限制性的例子,装置410或软件操作的一部分可能发生在如SIP代理服务器303或管理系统305等的服务提供商网络实体处,装置410的或软件操作的另一部分可能发生在服务提供商代理设备处。该装置的其他配置和装置的程序设计是本领域地技术人员知道和理解的。
【0033】存储器403耦合于CPU 407。存储器403,或计算机可读介质,可以是一个或多个已可用的存储器,比如随机存取存储器(RAM),只读存储器(ROM),软盘,硬盘,闪速存储器或任意其他形式的本地或远程的数字存储器。支持电路409被耦合于CPU407,以传统方式支持处理器。这些电路包括高速缓冲存储器,电源,时钟电路,输入/输出电路和子系统,等等。软件程序405当被CPU407执行时,使装置401执行本发明的过程并且通常被存储在存储器403中。软件程序405也可以被存储在第二CPU中和/或被第二CPU执行,第二CPU被置于远离由CPU 407所控制的硬件的地方。
【0034】当管理可配置装置401和管理系统305间数据传输的优选方法需要时,软件程序405被执行。软件程序405当被CPU 407执行时,把通用计算机转换成控制基于网络应用、诊断工具包或其他相似作用的专用计算机(装置)401。尽管本发明的过程以作为软件程序实现的方式加以讨论,但其中公开的方法中的某些步骤可以通过硬件和软件装置执行。同样,本发明可以当在计算机系统上执行时以软件来实现、以专用集成电路或其他类型的硬件来实现、或者以软件和硬件的结合来实现。本发明的软件程序405能够在包括但不限于Microsoft Windows98,Microsoft Windows 2000/XP/Vista,FreeBSD,NetBSD,Apple OS X和Linux等的计算机操作系统上被执行。相似的,本发明的软件程序405能够用包括但不限于IBMPower PC,Intel x86,Sun SPARC,AMD,Transmeta,MIPS,和ARM的CPU体系结构执行。
【0035】需要强调的是,上述的实施例,尤其是任意“优选”实施例,只是执行的可能的例子,只是为了清楚理解本公开发明的原理被提出。可以对上述本公开发明的实施例做许多变化和修改,而不实质性地偏离本公开发明的主旨和原理。所有这些修改和变化都被包括在这里本公开发明的范围之内,并且被下述权利要求保护。
【0036】这里公开的用于管理数据传输的实施例可以使用具有被专用或通用计算机执行的计算机可读代码的计算机可用介质来实现。
