+.RS 4
+Prefers the fastest responding face, and performs experiments to determine if other faces can provide faster response\&. This strategy also operates efficiently in environments where link quality changes or a face becomes unresponsive, but does not make use of multiple paths or sources\&.

+\fBloadsharing\fR
+.RS 4
+Distributes Interests amongst the available faces based on the unanswered queue size\&. This strategy operates most efficiently when there are multiple physical interfaces and the network is the limiting performance factor\&. Because it sends each interest to a single face, it is not recommended for chat\-like or discovery applications, or in the presence of lossy links\&.
+.RE
+.PP
+\fBparallel\fR
+.RS 4
+Sends Interests to all available faces in parallel\&. This strategy attempts to mask unstable links or poorly performing faces by redundantly sending Interests\&. This increases the overall network load and local processing overhead, and is not recommended when the links are of high quality\&.
