A method includes capturing traffic at a source domain and a destination domain, creating a first traffic digest comprising unique packet identifiers representing traffic captured at the source domain, creating a second traffic digest comprising unique packet identifiers representing traffic captured at the destination domain, comparing the first traffic digest to the second traffic digest, if a loss is detected based on the comparing step, identify an alternative path between the source domain and the destination domain, switching processing to the alternative path, and resynchronizing traffic between the source domain and the destination domain on the alternative path.
