Description

三层接口IP地址冲突的检测方法及装置 技术领域
本发明涉及计算机领域，具体而言，涉及一种三层(Level Three)接口IP地址冲突的检测方法及装置。
背景技术
网络之间的互联协议(Internet Protocol简称为IP)地址是计算机在互联网上的一个编号。正常的情况是每台联网的计算机都需要有IP地址才能正常通信。把“计算机”比作“电话”，那么“IP地址”就相当于“电话号码”。“电话号码”不能出现冲突(即相同)的情况，同理IP地址也不能出现冲突(即相同)的情况。
传输设备间传输数据的时候需要创建三层接口，三层接口有很多种类，比如：三层虚拟局域网(Virtual Area Network简称为VLAN)接口、三层以太网端口、三层以太子端口。传输设备的三层接口需要配置一个IP地址，由传输设备组成的网络中所有传输设备的三层接口的IP地址不可以冲突，如果IP地址冲突，就会导致网络中的数据传输失败，使正常的网络通信受到影响。
由传输设备组成的网络分为两个组成部分：若干个私网和公网。一个私网代表属于一个子网的所有三层虚拟专用网络(Level Three Virtual Private Network简称为L3VPN)；公网代表所有私网以外的网络。还是用电话作类比，私网好比是一个公司内部的电话网络，公网好比是所有公司内部电话网络以外的电话网络。公司内部的电话网络中不能有重复的电话号码，所有公司内部电话网络以外的电话网络中也不能有重复的电话号码。同理，私网和公网内也不能有冲突的IP地址。
相关技术中网管只提供了在各个种类的三层接口各自的配置功能中进行冲突检测的方法，而在某些种类的三层接口配置功能中还没有提供冲突检测。因此，相关技术中只能最低限度的保证某些种类的三层接口的IP地址不冲突，无法保证全网所有种类的三层接口的IP地址都不冲突。进而，如果出现了IP地址冲突的情况，相关技术无法立即获取到出现IP冲突的地址信息，只能在数据传输出现问题的情况下，通过配置人员手工排查的方式才能找出冲突的IP。
针对相关技术中在出现三层接口的IP冲突时，无法针对全网所有种类的三层接口的IP进行检测的问题，目前尚未提出有效的解决方案。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本实施例提供了一种三层接口IP地址冲突的检测方法，图1是根据本发明实施例的三层接口IP地址冲突的检测方法的流程图，如图1所示，该方法的步骤包括：
步骤S102：获取由传输设备组成的网络中全网的三层接口的IP地址；
其中，全网的三层接口的IP地址包括子网名称相同的三层虚拟专用网络L3VPN组成的不同私网的三层接口的IP地址，以及除私网的三层接口之外的公网的三层接口的IP地址；
步骤S104：对全网的三层接口的IP地址进行IP地址冲突检测。
通过本发明实施例，采用获取由私网和公网组成的全网中三层接口的IP地址，通过对全网中的三层接口的IP地址进行IP地址冲突检测，解决了相关技术中在出现三层接口的IP冲突时，无法针对全网所有种类的三层接口的IP进行检测的问题，可以快速的检测出全网(公网和所有私网)所有种类的三层接口IP地址冲突，帮助用户快速定位出存在IP冲突的IP地址。
在本实施例中对全网的三层接口的IP地址进行IP地址冲突检测的方式有多种，在本实施例的一个实施方式中可选的实施方中通过以步骤对全网的三层接口的IP地址进行冲突检测：
步骤A：从全网的三层接口的IP地址中查找出私网的三层接口的IP地址；
步骤B：对私网的三层接口进行过滤获得公网的三层接口后，获得公网的三层接口的IP地址；
步骤C：对私网的三层接口的IP地址和公网的三层接口的IP地址进行IP地址冲突检测。

步骤S22：创建用于存储第一预设表中查询出的公网的三层接口以及公网的三层接口的IP地址的第二预设表。
为了使用户能够方便快捷的查找到存在冲突的IP地址，在本实施例一个可选实施方式中采用了将显示对全网的三层接口的IP地址进行IP地址冲突检测后获得的检测结果。当然，其他能够快速通知用户IP冲突地址信息的方式也在本发明的保护范围之内。

可选地，检测单元还设置为，建立私网名称与私网名称对应私网下三层接口集合的映射关系；根据该映射关系，查询每个私网所包括的三层接口的IP地址中存在IP地址冲突的三层接口的IP地址；遍历全网中所包括的每个私网，记录私网名称、IP地址冲突的三层接口和IP地址冲突的三层接口的IP地址。
可选地，检测单元还设置为，创建用于存储全网中所有三层接口以及全网中所有三层接口的IP地址的第一预设表；创建用于存储第一预设表中查询出的公网的三层接口以及公网的三层接口的IP地址的第二预设表；通过对第二预设表执行预定查询语句的方式，对公网的三层接口的IP地址进行IP地址冲突检测。

需要说明的是，装置实施例中描述的短信的处理装置对应于上述的方法实施例，其具体的实现过程在方法实施例中已经进行过详细说明，在此不再赘述。
下面结合本发明可选实施例及附图对本发明进行举例说明。
本发明优选实施例提供一种简便、高效的检测出全网所有种类的三层接口IP地址冲突的方法。图5是根据本发明可选实施例的检测出全网所有种类的三层接口IP地址冲突的方法的流程图，如图5所示，该流程包括以下步骤：
步骤S502：在网管的数据库中创建一张表1，用来存储所有种类三层接口及三层接口的IP地址；
其中，表1对应于上述的第一预设表，该表是为了方便接下来的查询。
步骤S504：在网管的数据库中创建一张表2，用来存储属于公网的三层接口及三层接口的IP地；
其中，表2对应于上述的第二预设表，在表的三层接口的IP地址列创建索引，此索引用来完成冲突IP地址的快速检索。
步骤S506：查询出所有的L3VPN；
其中，查询结果包括L3VPN属于的子网名称和L3VPN包括的三层接口。子网名称相同的所有L3VPN为一个私网。根据查询结果生成两组数据：
a)私网名称和该私网的三层接口集合存储在一个映射中；
b)所有私网的三层接口存储在一个集合中。
步骤S508：查询所有网元的三层接口和三层接口的IP地址；
其中，利用步骤S506的b)数据对查询结果进行过滤，不属于步骤S506的b)数据中的三层接口属于公网的三层接口。将公网的三层接口和及其三层接口的IP地址存储在步骤S504创建的表中。
步骤S510：对数据进行IP地址冲突检测；
其中，遍历所有的私网，每个私网都进行如下的操作：
步骤a：查询私网的三层接口的IP地址；
步骤b：遍历IP地址并找出冲突的IP地址。记录私网名称、IP地址冲突的三层接口和这些三层接口的IP地址。
步骤S512：在数据库对步骤S504中创建的表执行查询语句，找出存在冲突的IP地址，记录IP地址冲突的三层接口和这些三层接口的IP地址。
步骤S514：从数据库中删除步骤S504创建的表。
步骤S516：记录的是私网和公网中IP地址冲突的三层接口及这些三层接口的IP地址，呈现检测结果。
相关技术的网管只提供了在各个种类的三层接口各自的配置功能中进行冲突检测，但是某些种类的三层接口配置功能中还没有提供冲突检测。因此，在相关技术中， 只能最低限度的保证某些种类的三层接口的IP地址不冲突，无法保证全网所有种类的三层接口的IP地址都不冲突。如果出现了IP地址冲突的情况，则无法立即发现问题，只能在数据传输出现问题的情况下，通过配置人员手工排查的方式才能找出问题，也就是说相关技术中的这种方式效率低下而且无法立即发现存在冲突的IP地址。通过本发明可选实施例，可以快速的检测出全网(公网和所有私网)所有种类的三层接口IP地址冲突，并将检测结果呈现给用户，帮助用户快速定位出问题所在，避免了由于IP地址冲突造成的一系列问题。
下面结合本发明可选实施例中的一个可选实施方式对本发明做进一步的说明。该实施例子是：

}
利用Set{三层接口4、三层接口5、三层接口6、三层接口7、三层接口8、三层接口9}对查询结果进行过滤，过滤出公网的三层接口为Set{三层接口1、三层接口2、三层接口3}，将公网的三层接口和三层接口的IP地址存储在步骤1创建的表中，存储的数据如下：
Set
{
三层接口1，IP地址是10.8.22.1
三层接口2，IP地址是10.8.22.2
三层接口3，IP地址是10.8.22.1
}
