参考答案和解析
答案：C
解析：
执行基于IP的DoS攻击，有不同的方法。最常见的基于IP的DoS攻击是攻击者发送大量连接建立请求（例如，TCP SYN请求）以建立与控制器或DPS的挂起连接。这样，攻击者就可以消耗合法用户所需的网络资源。在其他情况下，攻击者通过用随机值欺骗全部或部分头字段，向数据域中插入大量假数据包。这些传入的数据包将触发表丢失，并在流请求消息中发送大量到网络控制器造成控制器资源饱和。在某些情况下，获得DPS访问权的攻击者可以在流请求消息中人为地生成大量随机包，以使控制通道和控制器资源饱和。此外，DPS间的多样性不足也助长了此类攻击的快速传播。传统的移动回程设备由于其复杂性以及是供应商专属设备，天然是防止攻击传播的。此外，传统的移动回程设备不需要与核心控制器频繁通信，而DPS与中央控制器的通信则需要频繁通信。这些特性降低了DoS攻击的影响和传播。此外，传统的回程设备是由多个网络元素共同控制的。例如，单一的长期演化（LTE）基站连接多达32个MME（负责信令处理的关键节点）。因此，对单个核心元素的DoS/DDOS攻击不会终止回程设备或网络的整个操作。
