"# Analyzing the Impact of Failures (and letting loose a Chaos Monkey)\n",
"\n",
"Planned (maintenance) and unplanned failure of nodes and interfaces in the network is a frequent occurrence. While most networks are designed to be tolerant to such failures, gaining confidence that they are in fact tolerant is difficult. Network engineers often reason about network behavior under failures manually, which is a complex and error-prone task. Consequently, the network could be one link failure away from an outage that leads to a massive loss of revenue and reputation.\n",
"\n",
"Fortunately, based just on device configurations, Batfish makes it easy to *proactively* analyze the network behavior under failures and offer guarantees on its tolerance to a range of failure scenarios. \n",
"\n",
"In this notebook, we will show how to use Batfish to analyze network behavior under failures. Specifically, we will describe how to simulate a specific network failure scenario, how to check forwarding changes for all flows in that scenario, and finally how to identify vulnerabilities using Chaos Monkey style testing.\n",

"In the code, `bf.fork_snapshot` accepts four parameters: `BASE_SNAPSHOT_NAME` indicates the original snapshot name, `FAIL_LONDON_SNAPSHOT_NAME` is the name of the new snapshot, `deactivate_nodes` is a list of nodes that we wish to fail, and `overwrite=True` indicates that we want to reinitialize the snapshot if it already exists.\n",
"\n",
"In addition to `deactivate_nodes`, `bf.fork_snapshot` can also take `deactivate_interfaces` as a parameter to simulate interface failures. Combining these functions, Batfish allows us to simulate complicated failure scenarios involving interfaces and nodes, for example: `bf.fork_snapshot(BASE_SNAPSHOT_NAME, FAIL_SNAPSHOT_NAME, deactivate_nodes=FAIL_NODES, deactivate_interfaces=FAIL_INTERFACES, overwrite=True))`."

As an example, to ensure that the flows from `Paris` would still reach `PoP` even if `London` failed, we can run the traceroute question on the snapshot in which London has failed, as shown below. (See the [Introduction to Forwarding Analysis using Batfish](https://github.com/batfish/pybatfish/blob/master/jupyter_notebooks/Introduction%20to%20Forwarding%20Analysis.ipynb) notebook for more forwarding analysis questions)."

"Above, we saw how Batfish can create new snapshots that simulate failure scenarios and run analysis on them. This capability is useful to *test* the forwarding behavior under interesting failure scenarios. In some cases, we may also want to *verify* that certain network failures have no impact to the network, i.e., the forwarding behavior of *all* flows would not be changed by those failures. \n",
"\n",
"We now show a powerful question `differentialReachability` of Batfish, which allows us to analyze changes of *any* flow between two snapshots. This question will report any flow that was successfully delivered in the base snapshot but will not be delivered in failure snapshot or the other way around---not delivered in the base snapshot but delivered in the failure snapshot. \n",
"\n",
"Let us revisit the scenario where `London` fails. To understand if this failure impacts any flow to the PoP in the `US`, we can run the differential reachability question as below, by scoping the search to flows destined to the `PoP`(from anywhere) and comparing `FAIL_LONDON_SNAPSHOT_NAME` with `BASE_SNAPSHOT_NAME` as the reference. Leaving the headers field unscoped would search across flows to all possible destinations. "

Such testing is known to be highly effective but is not possible to do in the networking context. Until now.\n",
