摘要

我们提出NetCheck,一种用于验证大规模网络基础设施的网络策略语言。NetCheck的表现力足以捕捉基本的网络属性,如可达性和维护,以及更复杂的行为,如端到端连接,流量隔离或隧道不变性。NetCheck是全自动的,不需要对网络进行任何干预。它部署在自动生成的网络数据平面模型上,用SEFL语言表示。NetCheck依靠符号执行来探索网络中所有可行的路径。

Verifying large-scale networks using NetCheck
We present NetCheck, a network policy language for verifying large-scale networked infrastructures. NetCheck is expressive enough to capture basic network properties such as reachability and maintenance, as well as more complex behaviours such as end-to-end connectivity, traffic isolation or tunnel invariance. NetCheck is fully-automated, and does not require any intervention on the network under scrutiny. It is deployed on an automatically-generated model of the network data plane, expressed in the SEFL language. NetCheck relies on symbolic execution for exploring all feasible paths through the network.
