16 * @brief NetZone with an explicit routing computed at initialization with Floyd-Warshal
18 * The path between components is computed at creation time from every one-hop links,
19 * using the Floyd-Warshal algorithm.
21 * This result in rather small platform file, slow initialization time, and intermediate memory requirements
22 * (somewhere between the one of @{DijkstraZone} and the one of @{FullZone}).
