> +to disable the spin bit either globally or on a per-connection basis. Even when
+the spin bit is not disabled by the administrator implementations MUST disable
+the spin bit on a randomly chosen fraction of connections. The random selection
+process SHOULD be designed such that on average the spin bit is disabled for at
+least one eighth of network paths. The selection process should be externally
+unpredictable but consistent for any given combination of source and destination
+address and port. The selection process performed at the beginning of the
+connection SHOULD be applied for all paths used by the connection.
+
+In case multiple connections share the same five-tuple, i.e. same source and
+destination IP address and UDP port the setting of the spin bit needs to be
+coordinated across all connections to ensure a clear signal to any on path
+measurement point, however that might not be feasible.
+
+When the spin bit is disabled, endpoints MAY set the spin bit to any value, and
+MUST accept any incoming value. It is RECOMMENDED that they set the spin bit to
