-/** \class BestRouteStrategy
- *  \brief a forwarding strategy that forwards Interest
- *         to the first nexthop
+/** \brief Best Route strategy version 1
+ *
+ *  This strategy forwards a new Interest to the lowest-cost nexthop
+ *  that is not same as the downstream, and does not violate scope.
+ *  Subsequent similar Interests or consumer retransmissions are suppressed
+ *  until after InterestLifetime expiry.
+ *
+ *  \deprecated This strategy is superceded by Best Route strategy version 2,
+ *              which allows consumer retransmissions. This version is kept for
+ *              comparison purposes and is not recommended for general usage.
