 def _x_tune_ok(self, channel_max, frame_max, heartbeat):
 """Negotiate connection tuning parameters This method sends the client's connection tuning parameters to the server. Certain fields are negotiated, others provide capability information. PARAMETERS: channel_max: short negotiated maximum channels The maximum total number of channels that the client will use per connection. May not be higher than the value specified by the server. RULE: The server MAY ignore the channel-max value or MAY use it for tuning its resource allocation. frame_max: long negotiated maximum frame size The largest frame size that the client and server will use for the connection. Zero means that the client does not impose any specific limit but may reject very large frames if it cannot allocate resources for them. Note that the frame-max limit applies principally to content frames, where large contents can be broken into frames of arbitrary size. RULE: Until the frame-max has been negotiated, both peers must accept frames of up to 4096 octets large. The minimum non-zero value for the frame- max field is 4096. heartbeat: short desired heartbeat delay The delay, in seconds, of the connection heartbeat that the client wants. Zero means the client does not want a heartbeat. """
