/**
 * Interface for Deaggregator Service of Artemis.
 *
 * When a prefix hijacking is detected, ARTEMIS automatically launches its mitigation service (deaggregator).
 * Since in Internet routing the most specific prefix is always preferred, ARTEMIS modifies the BGP configuration of
 * the routers so that they announce deaggregated sub-prefixes of the hijacked prefix (that are most preferred from any
 * AS). After BGP converges, the hijacking attack is mitigated and traffic flows normally back to the ARTEMIS-protected
 * AS (the one that runs ARTEMIS). Therefore, ARTEMIS assumes write permissions to the routers of the network, in order
 * to be able to modify their BGP configuration and mitigate the attack. The purpose of this service is to receive all
 * hijack events from the detector service and proceed on writing all the new prefixes to be announced by the BGP
 * Speakers.
