}
- 第一个模块 configurator ，继承自Ipv4NetworkConfigurator（终于有个好好注释的源文件了：
Ipv4NetworkConfigurator.ned
package inet.networklayer.configurator.ipv4;
import inet.networklayer.configurator.base.NetworkConfiguratorBase;
//该模块为IPv4网络分配IPv4地址，并设置静态路由。
//它按接口分配IP地址，尽量考虑子网，还可以通过合并路由表项来优化生成的路由表。
//重要提示:从INET 2.2开始，这个模块不会直接分配地址或添加路由，只是将它们存储在内部数据结构中。网络节点应该包含一个~ ipv4nodeconfigator实例(通常是网络层复合模块的一部分)，该实例根据存储在全局网络配置器模块中的信息实际配置节点的接口表和路由表。
//配置器支持手动和自动地址分配以及它们的组合。您可以提供不指定部分的地址和子网掩码模板，配置器通过尝试将同一LAN中的节点放入同一子网来自动完成它们。它还支持手动路由和遵循最短路径的自动路由。默认情况下，配置器在适用的地方添加默认路由(例如在主机中)，并进行基于子网的路由。
//与节点数量相比，只需使用一小部分配置条目就可以建立分层路由。配置器还会对路由表进行优化，以显著减少大型网络中的路由表的大小。
//
// 以上大多数特性都可以使用NED参数打开和关闭。详细信息(接口地址和子网掩码模板、手动路由等)可以在整个网络的单个XML文件中配置。
// 表示网络节点(主机、集线器、总线、交换机、接入点、路由器等)的模块应该具有@ networkknode属性，因为这是配置器在模型中识别它们的方式。所有节点必须将其接口表(~InterfaceTable模块)作为其“InterfaceTable”子模块。
// 所有路由器都必须有它们的路由表(~Ipv4RoutingTable模块)作为它们的“routingTable”或“networkLayer”。routingTable”子模块。
// 默认情况下，所有节点的所有接口都将分配一个唯一的IPv4地址。路由表将被配置为从任何节点到任何接口都有一条遵循最短路径的路由。换句话说，所有接口都可以从所有节点访问(例如ping)。
// 配置器不连接任何其他模块(它没有门)，并且在整个模型中应该只有一个实例。配置发生在初始化阶段2，在~InterfaceTable模块中注册接口之后。
//
// 配置器的配置步骤如下:
//
//
-# 构建表示网络拓扑的图。图将为每个具有@ networkknode属性的模块分配一个顶点(这包括主机、路由器和L2设备，如交换机、接入点、以太网集线器等)。它还为在设置路由时将被最短路径算法使用的顶点和边分配权重。对于禁用了IP转发(以防止路由传输它们)的IP节点，权值将是无限的，而对于所有其他节点(路由器和L2设备)，权值将为零。选择的边权值与链路的比特率成反比，这样配置者就会优先选择带宽较高的连接。对于内部目的，配置器还构建一个所有“链路”的表(链路数据结构由同一点对点链路或LAN上的一组网络接口组成)
//
//
-# 为所有节点的所有接口分配IP地址。分配过程考虑到接口上已经存在的地址和网掩码(可能在早期初始化阶段设置)，以及XML格式提供的配置(如下所述)。配置可以为地址和网掩码指定“模板”，其中的部分是固定的，部分可以由配置器选择(例如。“10.0.x.x”)。在最一般的情况下，配置器被允许为所有接口选择任何地址和网掩码(这导致自动地址分配)。在最受限制的情况下，配置器被迫为所有接口使用请求的地址和网掩码(转换为手动地址分配)。在这两个极端之间有许多可能的配置选项。配置器以一种使每个子网的节点数量最大化的方式分配地址。一旦它找出了属于一个子网的节点，就会优化分配尽可能长的网络掩码。配置器可能无法根据给定的配置参数分配网络掩码和地址;如果发生这种情况，分配过程停止并发出错误信号。
//
//
-# 添加配置中指定的手动路由。
//
//
-# 向网络中所有的路由表添加静态路由。配置器使用Dijkstra的加权最短路径算法在所有可能的节点对之间找到所需的路由。产生的路由表将为网络中的所有目的接口提供一个条目。可以安全地指示配置器在适用的地方添加缺省路由，从而大大减少主机路由表的大小。它还可以增加子网路由而不是接口路由，从而进一步减小路由表的规模。开启这个选项需要仔细设计，以避免在不同的链路上有来自同一子网的IP地址。注意:同时使用手动路由和静态路由生成可能会产生不必要的副作用，因为路由生成忽略了手动路由。
//
//
-# 然后根据大小优化路由表。这种优化允许用更小的内存占用配置更大的网络，并使路由表查找更快。产生的路由表可能不同，因为它将路由原始路由表没有路由的数据包。尽管如此，下列不变式保持不变:由原始路由表路由的任何数据包(有匹配的路由)仍将以相同的方式由优化后的路由表路由。
//
//
-# 最后，它转储配置请求的结果。它可以转储网络拓扑，分配的IP地址，路由表和自己的配置格式。
//
// 下面以配置IPv4地址范围内的所有接口为例
// 10.0.0.0 - 10.255.255.255, and netmask range 255.0.0.0 - 255.255.255.255.
// This is the default configuration.
//10.0.0.0 - 10.255.255.255，子网掩码范围为255.0.0.0 - 255.255.255.255。这是默认配置。
// <pre>
// <config>
//
<interface hosts='**' address='10.x.x.x' netmask='255.x.x.x'/>
// </config>
// </pre>
//
//下面的示例以一种保持路由表较小的方式配置分层网络。
// <pre>
// <config>
//
<interface hosts="area11.lan1.*" address="10.11.1.x" netmask="255.255.255.x"/>
//
<interface hosts="area11.lan2.*" address="10.11.2.x" netmask="255.255.255.x"/>
//
<interface hosts="area12.lan1.*" address="10.12.1.x" netmask="255.255.255.x"/>
//
<interface hosts="area12.lan2.*" address="10.12.2.x" netmask="255.255.255.x"/>
//
<interface hosts="area*.router*" address="10.x.x.x" netmask="x.x.x.x"/>
//
<interface hosts="*" address="10.x.x.x" netmask="255.x.x.0"/>
// </config>
// </pre>
//XML配置必须恰好包含一个<config>元素。</config>在根元素下可以有以下元素的倍数。
//
- <interface>
//
The interface element provides configuration parameters for one or more
//
interfaces in the network. The selector attributes limit the scope where

the interface element has effects. The parameter attributes limit the
//
range of assignable addresses and netmasks.

the hierarchy, and other patterns similar to ini file keys. The default
//
value is "*" that matches all hosts.
//
e.g. "subnet.client*" or "host* router[0..3]" or "area*.*.host[0]"
//接口元素为网络中的一个或多个接口提供配置参数。选择器属性限制了接口元素的作用域。参数属性限制了可分配地址和网络掩码的范围。
//- @hosts可选的选择属性，指定主机名模式列表。
//只有指定主机的接口受影响。模式可以是从网络开始的完整路径，也可以是层次结构中任意位置的模块名，以及其他类似于ini文件键的模式。系统默认值为“*”，匹配所有主机。如。“子网。客户端*"或"主机*路由器[0..3]”或“区域*。* .host[0]”

the same LAN with the one that is being configured. This works even if
//
there's a switch between the configured host and the one specified here.

For wired networks it might be easier to specify this parameter instead
//
of specifying the interface names. The default value is "*".
//
e.g. "ap" or "server" or "client*"
//指定主机名模式列表的可选选择器属性。只有连接到指定主机的接口受影响。指定的名称将与正在配置的主机在同一局域网内的主机名称进行匹配。即使在配置的主机和这里指定的主机之间有一个切换，这也可以工作。对于有线网络，指定这个参数可能比指定接口名称更容易。系统默认值为“*”。如。"ap"或"服务器"或"客户端*"
