<p class="MsoNormal"><span style="font-size:14.0pt">The SIS Area would like to transition the project ‘Contact Graph Routing for CCSDS’ from ‘Pending’ to ‘Active’. The SIS Area believes that the Contact Graph Routing task can be accomplished with NO ADDITIONAL
agency resources beyond those that have been provided in the past for the production of the LTP and BP specifications. [The LTP and BP work is winding down, and we expect the documents to be published by the middle of calendar year 2015.]<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt">The Contact Graph Routing specification will define the decision process for bundle forwarding, given a set of link contacts (which imply a topology) and a set of bundles (sources, destinations, injection
times). The rationale for standardizing contact graph routing is that the decision processed by different DTN Nodes (Routers) need to be consistent so that bundles do not loop (and then die).<o:p></o:p></span></p>
