我们相信，一个网络要想生存，就必须是异构的。就像利用小型基因库的物种可能会屈服于单一环境威胁一样，同质网络也容易受到利用其所有组件共有的单一弱点的恶意攻击。相比之下，在每个关键功能都由一组不同的协议和实现提供的网络中，即使所有元素都不是万无一失的，即使某些组件受到损害，针对某个此类协议或实现的弱点的攻击也无法摧毁整个网络。遵循这种通过异构性实现生存的理念，我们提出了一种新的生存性范式，称为异构网络，用于提高网络的防御能力。这种方法不是遵循当前趋同于单一解决方案以在网络架构的每个元素上提供所需功能的趋势，而是要求系统地增加网络的异构性而不牺牲其互操作性。
We believe that a network, to be survivable, must be heterogeneous. Just like a species that draws on a small gene pool can succumb to a single environmental threat, so a homogeneous network is vulnerable to a malicious attack that exploits a single weakness common to all of its components. In contrast, in a network in which each critical functionality is provided by a diverse set of protocols and implementations, attacks that focus on a weakness of one such protocol or implementation will not be able to bring down the entire network, even though all elements are not be bulletproof and even if some of components are compromised.Following this survivability through heterogeneity philosophy, we propose a new survivability paradigm, called heterogeneous networking, for improving a network's defense capabilities. Rather than following the current trend of converging towards single solutions to provide the desired functionality at every element of the network architecture, this methodology calls for systematically increasing the network's heterogeneity without sacrificing its interoperability.
