1.导论
PINT服务是以新兴的Internet趋势,基于在Internet上传输的对于PSTN(公共交换
电话网络)的声音(和传真)请求的应用。RFC 2548[1]给出了一个很好的关于(预先标
准)PINT体系机构和服务的介绍。同样它也提供了某些pre-PINT的早期执行的例子。
这篇文章定义了MIB,它包含了监测以服务为基础的PINT性能的原理.MIB由在各种各样
标准下测量四种基本PINT服务和它们的表现统计的详细资料构成。
有助于PINT网络化原理的管理并不是MIB的目的。我们关心的仅是PINT特定的执行参
数。在它则是懂得紧密把PINT服务运行与主机和网络运行联系起来,他们并不从事于此。
2.SNMP管理框架
SNMP架构目前与五个主要部分构成:
O在RFC 2571 [2] 中所描绘的全面体系机构。
O描述和命名管理目的的对象和事件机制.这个管理信息结构(SMI)的最初版本命名为
SMIv1并在STD 16, RFC 1155 [3], STD 16, RFC 1212 [4] 和 RFC 1215 [5]中有所描述.
第二个版本被命名为SMIv2并在STD 58,RFC 2578 [6], RFC 2579 [7] 和 RFC 2580 [8]中
有所描述。
O传输管理信息的通信协议。SNMP通信协议的最初版本被命名为SNMPv1并在STD 15,
RFC 1157 [9]中有所描述。SNMP通信协议的第二个版本,它并不是Internet标准追踪协议,
被称为SNMPv2c并在RFC 1901 [10] 和 RFC 1906 [11]中有所描述。通信协议的第三个版
本被称为SNMPv3并在RFC 1906 [11], RFC 2572 [12] 和 RFC 2574 [13]。
O访问管理信息的协议操作。协议的操作和与PDU相关的格式的最初设置在STD 15, RFC
1157 [9]中有所描述。协议的操作和与PDU相关的格式的第二个设置在RFC 1905 [14]中有
所描述。
O基本应用程序的设置在RFC 2573 [15]中有所描述,基于访问的存取控制机制在RFC
2575 [16]中有所描述。
在RFC 2570 [17]中有更多关于通用SNMP管理框架的详尽描述。
通过有效的信息存储来访问管理对象,被称为管理信息基础或MIB。在MIB中的对象是
使用在SMI中已定义的机制来定义的。
这篇备忘录详细说明了符合SMIv2的MIB模式。符合SMIv1的MIB能通过适当的转换进
行制造。作为转换结果的MIB必须在语义上等价,除非对象和事件因为没有转换的可能而被
省略(使用Counter64)。在SMIv2中一些可用计算机处理的信息在转换进行时,会被转变
成SMIv1中的文本描述。尽管如此,这些可用计算机处理的信息的丢失并不认为会改变MIB
的语义。
3.监测MIB的PINT服务体系的需求
传统的声音(和传真)请求在PSTN网络中发生和终止。这个网络在有效性和安全性
的条件下,因处理请求的强大功能而出名。但是,当请求在Internet上产生时,会在某些
问题方面涉及到用户方和提供方,就像在各种网络条件下对于PINT网关的可靠的呼叫请求,
客户/主机验证,用户信息的安全操作等等。在PINT服务通过多重管理域(或供应商),执
行和安全管理就变得至关重要。
这种MIB是对需要在用户,PINT客户端,PINT服务器和PINT网关基础进行监控的已详
细列出的参量的一种尝试。
(PINT服务,它们的方法/协议和涉及到安全的PINT体系机构在[18]中有详细讨论)。
4.PINT MIB总述
下面给出了一个列表,包含了我们已选择来建立的MIB定义的一些说明。
O这种MIB的基本目的是从执行和安全观点监控PINT服务的使用权。信息可能适合于
某一个用户或是他/她的系统(PINT客户端)或是提供PINT服务的系统(PINT服务器)或
是PINT网关,是对于PSTN的前方命令。
O我们选择建立一个结构表,作为应用MIB的扩展-使用增加结构的RFC 2287 [19]。服
务器的位置和联系可能会从标准的MIB-II sysLocation和sysContact对象中获得。但是,
PINT管理员可能与具有全局职责的sysadmin不是同一个人,因此定义了一个
pintSysContact对象。
O我们选择从PINT服务器来监测网关的连接。当代理在PINT服务器上运行时,通过网
关的连接可能需要被监测,以便知道它的运行情况。我们把它们置于一个独立的MIB组,通
过使用MODULE-COMPLIANCE条款,代理如果不能实现这种填充,那它将不被委托。
O在MIB模块并不带有随身的定义。注意,通过使用由Remote Monitoring MIB定义的
标准机制,计数器的开始就始终有可能,在此作为参考。一些事件可能有以下机制来定义:
? 客户端或用户接收到的持续的注册/验证错误或拒绝
? 由同一用户对一个号码发出的恶意地重复(在一个特定时期内)请求
O客户端和用户的执行平台可能对了代理执行的资源过分苛求。在一些MIB里,比如
Remote Monitoring (RMON) MIB,建立了控制机制以便激活需求上的统计值。如果需要的话,
一个分类(“topN”)协议能被建立,这样以来一个客户端和用户的分类表就阻止了高级别
的错误的产生。
O我们建立了一个时间分布状态,试图覆盖短暂的和长的sessions(1-10秒,10秒-1
分钟,1-15分钟,15分钟-24小时,甚至更长)。
OPintServerClientAddress被定义成SnmpAdminString。它可能包含一个IpAddress
以及/或名字,但是我们宁愿减少这个进程中的指标数,并同时保留人可读的格式。
O我们把PintServerUserIdName定义为UserId。这个UserId通过多重的PINT服务器
和网关(依赖于体系机构)而是唯一的,并映射为SessionId。达到唯一性的一种途径就是
在发送给PINT服务器以前,在UserId字符串中添加clientId。SessionId就可能是这个新
的UserId和timestamp的组合。

作者要特别感谢Igor Faynberg,由于他对完成这篇作品的鼓励。
7.安全考虑
在这种MIB中只定义了唯一的一个管理对象,它包含MAX-ACCESS读-写子句
(pintSysContact)。没有读-创建对象。这种读-写对象可能在某些网络环境中可能十分敏
感或易受攻击。在没有适当保护的不安全环境中对SET操作的支持在网络运行上有消极的作
用。
在这种MIB中有一定数量的管理对象,可能包含对商业前景敏感的信息。其一可能就是
顾客的验证(UserIdName)。同样的,PINT服务运行的信息自身需要受到监控。因此,当
通过SNMP在网络上发送时,对于这些对象的适当GET存取或者对于这些对象的值的合理加
密的控制就变得十分重要。不是所有的SNMP译文都提供这样的安全环境特色。
SNMPv1自身并不是一个安全环境。尽管网络本身是安全的(例如使用IPSec),即使那
样,它并不包含对于在安全网络上谁被允许存取和GET/SET(读/更改/创建/删除)在这种
MIB中的对象的控制。
建议执行者像SNMPv3框架那样考虑安全特性。特别是, 推荐使用User-based Security
Model RFC 2574 [13] 和 View-based Access Control Model RFC 2575 [16]。
确认SNMP实体给出了对这种MIB存取的实例就变成了客户/使用者的职责,合理地配置
那些仅对于某些首要的(用户)存取这些对象,并且他们确实有权限真正的GET或SET(更
改/创建/删除)它们。
8.IANA考虑
所有在这种MIB中列出的值的扩展必须通过在RFC 2434 [20]中定义的标准行为过程。
