+.SH "OPENFLOW IMPLEMENTATION"
+.
+.PP
+This section documents aspects of OpenFlow for which the OpenFlow
+specification requires documentation.
+.
+.SS "Packet buffering."
+The OpenFlow specification, version 1.2, says:
+.
+.IP
+Switches that implement buffering are expected to expose, through
+documentation, both the amount of available buffering, and the length
+of time before buffers may be reused.
+.
+.PP
+Open vSwitch maintain a separate set of 256 packet buffers for each
+OpenFlow connection.  Any given packet buffer is preserved until it is
+referenced by an \fBOFPT_FLOW_MOD\fR or \fBOFPT_PACKET_OUT\fR request
+or for 5 seconds, whichever comes first.
