Detailed Description

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.

Note
This strategy is superceded by Best Route strategy version 2, which allows consumer retransmissions.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.
This strategy is not EndpointId-aware.
