The static route computation strategy is
the default route computation mechanism in ns.
This strategy uses the
Dijkstra's all-pairs SPF algorithm ../ns-2/route.ccRouteLogic::compute_routes.
The route computation algorithm is run exactly once
prior to the start of the simulation.
The routes are computed
using an adjacency matrix and link costs of all the links in the topology.
(Note that static routing is static in the sense that it is computed
once when the simulation starts, as opposed to session
and DV routing that allow routes to change mid-simulation.
An alternative to static routing is Manual routing
where routes are not computed but instead are set (manually) by the user.)
