ITU-T L.392 PDF

This Recommendation describes an approach for improving network resilience and recovery by substituting healthy transportable and instantaneously deployable facilities for damaged ICT facilities; the substitutes are referred to as movable and deployable ICT resource units (MDRUs) throughout this Recommendation.

After introducing the substitution approach to network resilience and recovery, this Recommendation identifies key factors for examining various MDRU usage scenarios, and introduces one promising MDRU use as a local node. Focusing on this use, this Recommendation reviews target objectives of disaster management and gives high-level requirements for both operations and facilities as a guideline. To shorten deployment time, which is the primary objective of network recovery, this Recommendation shows how to optimize the substitution process, starting with equipment preparation for daily operation to service offering at the site of the disaster.
