+ * @brief Assigning numbers to router names.

+ * lookups between router names and their mapping numbers.
+ *
+ * These numbers are non-negative integers assigned sequentially, starting from zero. They can
+ * support constructing a matrix of routers, where the mapping numbers are used as row and column
+ * indices in place of router names.
