Detailed Description

NetZone with an explicit routing computed at initialization with Floyd-Warshal.

The path between components is computed at creation time from every one-hop links, using the Floyd-Warshal algorithm.

This result in rather small platform file, slow initialization time, and intermediate memory requirements (somewhere between the one ofDijkstraZone} and the one ofFullZone}).
