             The Network Trouble Ticket Data Model (NTTDM)

Abstract

   Handling multiple sets of network trouble tickets (TTs) originating
   from different participants' inter-connected network environments
   poses a series of challenges for the involved institutions.  A Grid
   is a good example of such a multi-domain project.  Each of the
   participants follows different procedures for handling trouble in its
   domain, according to the local technical and linguistic profile.  The
   TT systems of the participants collect, represent, and disseminate TT
   information in different formats.

   As a result, management of the daily workload by a central Network
   Operation Centre (NOC) is a challenge on its own.  Normalization of
   TTs to a common format at the central NOC can ease presentation,
   storing, and handling of the TTs.  In the present document, we
   provide a model for automating the collection and normalization of
   the TT received by multiple networks forming the Grid.  Each of the
   participants is using its home TT system within its domain for
   handling trouble incidents, whereas the central NOC is gathering the
   tickets in the normalized format for repository and handling.  XML is
   used as the common representation language.  The model was defined
   and used as part of the networking support activity of the EGEE
   (Enabling Grids for E-sciencE) project.
