发明领域
本发明总体涉及局域网,具体来说,涉及令牌环局域网中令牌的传递。
发明背景
计算机网络中各计算机通常共享有限数量的资源。在所共享的资源间分配访问的一种常规方法包含向网络中各计算机绕圈传递一“令牌”。各计算机提前达成一致的协议,即利用这种令牌协议时,只有拥有该令牌所有权的计算机才可以访问该资源。利用令牌传递算法的网络中一常用实例为令牌环网。
令牌环网是基带网,这是指该网络介质全部传输容量(即网络带宽)为一个信号所占用。因为整个网络一时只能传送一个信号,所以令牌环网中的多个计算机必须不同时传送。这种不同步传送是利用令牌访问协议实现的。
该令牌访问协议中,网络中各计算机达成一致让信息帧连续绕圈传送至网络中的全部计算机。当有一计算机要发送一短信息时,需等到其拥有空闲帧,然后修改该帧,在其中插入其短信息,目的识别符和“令牌”。该令牌在该帧中可以很简单地为例如一比特的字段,该进行插入的计算机将它修改为1表明存在令牌,或修改为0则表明为空闲帧。
帧沿网络传递时,每一计算机检查该帧。目的计算机对该帧当中的短信息进行复制后将令牌改回为0。始发计算机接收该帧时,可通过了解该令牌已设定为0来验证其短信息被接收。该始发计算机接着清除该帧当中的短信息,将该空闲帧传递给网络中下一计算机。
尽管现有的令牌环网在防止数据冲突方面很有成效,但仍存在诸多不足。具体来说,为了实施令牌环网,网络中的全部计算机必须提前就用于传递短信息帧的合适协议达成一致。例如网络系统管理员希望修改令牌环协议的话,由于每一计算机必须在网络运行前更新,因而这会很难办。所以希望对令牌环网加以改进。

图4是表示本发明方法的流程图。
详细说明
在所揭示的令牌环网中,在网络中各计算机之间传递的令牌对该令牌环网定义一协议或该协议中至少一部分。接收该令牌的网络中每一计算机对该令牌进行检查,并实施该令牌中所规定的网络协议。具有合适许可的任意计算机可以对该令牌进行修改或更新,由此修改整个网络的协议。
现具体参见本发明的实施例,即附图中图示的例子。
系统总览
图1是一令牌环网100高层面示意图,包括沿逆时针方向经网络介质120传递一令牌对象的4个分布式计算机102、104、106和108。最好是在利用诸如Java远程启用系统(Java RMI)这些远程对象传递机制中某些形式的计算机102-108间传递该令牌对象。另外,计算机102-108其中一个可以充当至一更大规模的令牌环网或至非令牌环网的网关。如图1所示,计算机106充当至互联网110的网关。
在示范性分布式系统100中,不同计算机和设备按联邦制形成为,对用户来说所显现的是单个系统。通过表现为单个系统,该分布式系统100在不放弃个人计算机或工作站灵活性和个性化响应的前提下,提供单个系统所能提供的对访问的简化以及共享能力。分布式系统100可以包含地理上分散但认同基本信念、系统管理以及政策的诸多用户所操作的数千个设备。
位于分布式系统100内的是对一个或多个设备所提供的业务进行不同的逻辑分组,每一这种逻辑分组称为Djinn。“业务”是指能够为用户、程序、设备或另一业务访问的,并能够计算、与存储有关、与通信有关、与向另一用户提供访问有关的资源、数据或功能程序。作为Djinn部分提供的业务例包括诸如打印机、显示器和盘这类设备;诸如应用程序或实用程序这类软件;诸如数据库和文档这类信息;以及系统用户。
用户和设备均可以加入Djinn。当加入Djinn时,用户或设备便向Djinn增加0或更多的业务,在安全约束下可以访问其所包含的任意一种业务。这样,设备和用户按联邦制形成为一Djinn来共享对其业务的访问。该Djinn的诸多业务在程序设计上表现为Java编程环境的诸多对象,它们可以包括其他对象、按不同编程语言写成的软件部件、或硬件设备在内。一业务具有一接口,定义可就那种业务请求的诸多操作,这类业务类型确定组成那种业务的诸多接口。
现参见图2简要说明Java RMI以及其与计算机102-108和令牌环网100之间的关系。
图2更加具体地示出计算机102来表示分布式系统100的若干软件部件。计算机102包括存储器202、第二级存储设备204、中央处理单元(CPU)206、输入设备208以及视频显示器210。该存储器202包括查询业务212、见证业务214和JavaTM运行时系统216。该JavaTM运行时系统216包括JavaTM远程方法启用系统(RMI)218和JavaTM虚拟机220。第二级存储设备204包括JavaSpaceTM222。
示范性的分布式系统100基于Java编程环境,因而利用Java运行时系统216。该Java运行时系统216包括Java API,允许Java运行时系统顶部上面运行的程序按与平台无关的方式访问包括主机操作系统视窗能力和联网能力在内的不同系统功能。因为Java API对移植Java运行时系统的全部操作系统总体提供单个公用API,因而不论是主机平台的操作系统还是硬件配置,运行于Java运行时系统顶部上面的各程序均按与平台无关的方式运行。Java运行时系统216作为位于加州景山的太阳微系统(Sun Microsystems)公司可供给的软件开发套件当中的部分来提供。
Java虚拟机220也有利于平台的无关性。Java虚拟机220象一摘要计算机那样运作,按字节代码形式从程序当中接收指令,并通过动态地将它们变换为诸如目标代码这种执行形式来解释这些字节代码,并执行它们。RMI 218通过允许在一个计算机或设备上执行对象来有利于远程方法启用,在另一计算机或设备上撤销一对象的诸多方法。RMI和Java虚拟机也作为Java软件开发套件的部分提供。
查询业务212定义对一特定Djinn可供给的诸多业务。也就是说,在示范性分布式系统100内可以有超过1个的Djinn,因而有超过1个的查询业务。该查询业务212在Djinn内每一业务包含一个对象,每一对象则包含有利于访问相应业务的种种方法。查询业务212及其访问在前面已通过引证归并的发明名称为“有利于访问查询业务的方法和系统”这一共同待审的美国专利申请U.S.Ser.No______中有更加详细的说明。
见证服务器214当有新设备加入到示范性分布式系统100时,在称为启动和加入或见证的处理期间进行检测,当检测有这一新设备时,见证服务器便向查询业务212传递一指向该新设备的参照,以便该新设备可将其业务与查询业务一起登录并成为Djinn一员。登录后,新设备成为该Djinn一员,从而可以访问查询业务212中包含的全部业务。该启动和加入处理在前面已通过引证归并的发明名称为“分布式系统中提供可下载代码用于与设备通信的装置和方法”这一共同待审的美国专利申请U.S.Ser.No.:______中有更加详细的说明。
JavaSpaceTM222是示范性分布式系统100中诸多程序用来存储对象的对象资源库。诸多程序利用JavaSpaceTM222来持久地存储诸多对象,并使之可由示范性分布式系统中的其他设备访问。Java空间(Java space)在已通过引证归并的发明名称为“利用多形态索引条目和索引条目匹配的数据库系统”、于1997年11月17日申请并转让给共同受让人的共同待审美国专利申请U.S.Ser.No.:08/971,529中有更加详细的说明。本领域技术人员会理解,示范性分布式系统100可包含许多查询业务、见证业务和Java空间(JavaSpaces)。
尽管本发明系统和方法按照说明是工作在示范性分布式系统和Java编程环境中的,但本领域技术人员会理解,本发明可以在其他系统和其他编程环境中实践。另外,尽管本发明的诸多方面按照说明是存储于存储器的,但本领域技术人员会理解,这些方面也可以存储于其他类型的计算机可读介质或由此读出,这些可读介质包括:诸如第二级存储设备,象硬盘、软盘、CD-ROM;诸如互联网(Internet)的载波;或其他形式的RAM或ROM。Sun,Sun Microsystems,SunLogo,Java,和基于Java的商标均属于美国和其他国家中太阳微系统公司(Sun Microsystems Inc.)的商标或注册商标。
多形态令牌的传递
本发明的令牌环网取代常规令牌环网中所用的静态令牌帧,而是围绕网络传递一多形态令牌对象。令牌对象的传递最好是利用诸如Java RMI(上面说明过)这种分布式面向对象的编程环境来实施。由于Java RMI对诸多分布式对象提供自动管理和在网络上方便地在机器间传递对象的能力,因而特别适合本发明。
图3是表示一示范性令牌302以及其与一令牌类层次304之间关系的示意图。令牌302最好是利用对象数据结构、和可包括功能程序(例如是法)和数据在内的这类数据结构来实施。本说明书中通篇所用的,也是面向对象编程领域中通常所用的“类”,指一据此可以定义诸多对象的模板。一对象是一特定类的一个实例,可包括使相同类中的诸多对象相区别的属性信息。诸多对象继承它们所依赖的类的行为。令牌对象302例如是“安全令牌”类305的实例,并继承该“安全令牌”类305的行为,而该“安全令牌”类305又继承“通用令牌”类303的行为。
如图所示,令牌对象302包括令牌在网络中传递顺序(例如逆时针方向)的定义法310,故障计算机所要使用的求救协议的定义法311,检查路由的网络诊断的定义法312,和网络所要实施的安全措施的定义法313。常规令牌环网的关联中,实施诸多法310-313所定义的功能程序的令牌环协议是众所周知的,故省略上述定义法的详细说明。
令牌302还包括:短信息数据字段314、目的地数据字段315和令牌数据字段316,其中每一个与前文对于常规令牌环网帧所说明的短信息、短信息识别符和令牌直接类同。
令牌类303定义一“令牌”所需要的通用功能程序。根据通用类303定义的诸多类和对象继承此功能程序。如图所示,令牌类303实施或部分实施定义法310-312和字段314-316。安全令牌类305是类303的分类,这样类305继承类303的功能程序。另外,分类305可以定义其自己的法和变量,包括例如网络安全措施定义法313。快速令牌306也是类303的一分类。快速令牌303可以包括对定义法310所定义的传递顺序作进一步定义的定义法317。
工作当中,网络100中每一计算机检查其所接收的令牌对象,并根据这种检查修改其用于实施该令牌环网的协议。若某一计算机希望修改网络的令牌环网协议,该计算机便通过更新、替换或增加一新定义法来简单修改令牌对象中的定义法。随着令牌对象沿网络的传播,而实施新协议。
图4是示出本发明方法的流程图。最好,只有经授权的计算机能够修改令牌环网协议来确保网络的完整性。若一计算机希望修改协议(步骤402),它具有合适的授权(步骤403),而当它对令牌对象拥有控制时,它通过增加或替换其定义令牌环协议的新定义法可简单地修改协议(步骤404)。可以通过由例如令牌中的字段或网络100中各计算机内部预先进行的硬连接设置来表示计算机是否具有授权来修改网络协议。
网络100中接收该令牌对象的各个计算机咨询该令牌对象,需要的话更新其网络协议的版本(步骤405)。计算机然后可相应地工作于该令牌上,并将该令牌传递给网络中下一计算机(步骤406)。
如同图4所示方法图示的那样,假定一计算机要将属于安全令牌类305一实例的当前令牌对象,修改为属于类306一实例的快速令牌对象。假定计算机经过授权修改该令牌对象,它将一直等到它接收到安全令牌对象,才用快速令牌对象替换安全令牌对象,对相应的协议咨询该快速令牌对象,然后再将该快速令牌对象传递给网络中下一计算机。
这里所图示和说明的是当前认为本发明中较佳的实施例以及方法,但本领域技术人员会理解,可以在不脱离本发明真实保护范围的前提下对其诸多单元进行种种改动和修改,并可以替换为等效部分。例如是参照基于Java(爪哇)语言的运行时环境来说明上述系统和方法的,但也可构思利用其他的运行时环境来实施本发明。此外,上述实施例是就令牌环网的关联加以说明的,但本领域普通技术人员中会理解,本发明的令牌对象也可等同地应用于网络所用的任意令牌传递算法。
另外,可以在不脱离本发明中心范围的前提下进行许多修改,针对本发明的示教对特定单元、技术或实施方案进行调整。因而,本发明并不是用于表明仅限于这里揭示的特定实施例和方法,而是用于表明本发明包含落在所附权利要求书保护范围内的全部实施例。
