+nfd-asf-strategy
+================
+
+SYNOPSIS
+--------
+| nfdc strategy set prefix <PREFIX> strategy /localhost/nfd/strategy/asf/%FD%02[/probing-interval~<PROBING-INTERVAL>][/n-silent-timeouts~<N-SILENT-TIMEOUTS>]
+
+DESCRIPTION
+-----------
+
+ASF is an Adaptive Smoothed RTT-based Forwarding Strategy that chooses the best next hop based on SRTT measurement, and also periodically probes other next hops to learn their RTTs.
+
+OPTIONS
+-------
+<PROBING-INTERVAL>
+ Tells ASF how often to send a probe to determine alternative paths.
+ The value is specified in milliseconds (non-negative integer)
+ Lower value means high overhead but faster reaction.
+ Default value is 1 minute and minimum value is 1 second.
+ It is optional to specify probing-interval.
+
+<N-SILENT-TIMEOUTS>
+ ASF switches immediately to another appropriate face (if available) upon timeout.
+ This behavior may be too sensitive for application use and appropriate only for link
+ failures and not transient timeouts. So this parameter makes ASF switch paths
+ only after it has encountered the specified number of timeouts (non-negative integer).
+ Default and minimum value is 0 i.e. switch immediately.
+ It is optional to specify n-silent-timeouts.
+
+EXAMPLES
+--------
+nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf
+ Use the default values.
+
+nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf/%FD%03/probing-interval~30000
+ Set probing interval as 30 seconds.
+
+nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf/%FD%03/n-silent-timeouts~5
+ Set n-silent-timeouts as 5.
+
+nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf/%FD%03/probing-interval~30000/n-silent-timeouts~5
+ Set probing interval as 30 seconds and n-silent-timeouts as 5.
