-/* This example shows how to serialize a set of communications going through a link
- *
- * As for the other asynchronous examples, the sender initiates all the messages it wants to send and
- * pack the resulting simgrid::s4u::CommPtr objects in a vector.
- * At the same time, the receiver starts receiving all messages asynchronously. Without serialization,
- * all messages would be received at the same timestamp in the receiver.
- *
- * However, as they will be serialized in a link of the platform, the messages arrive 2 by 2.
- *
- * The sender then blocks until all ongoing communication terminate, using simgrid::s4u::Comm::wait_all()
+/* This example shows how to react to a failed communication, which occurs when a link is turned off,
+ * or when the actor with whom you communicate fails because its host is turned off.
