748 * In general, data that is sent by the application is limited by the
749 * bandwidth of the channel. If you send data faster than this, it must be
750 * queued and put on the wire at a metered rate. Even sending a small amount
751 * of data (e.g. a few MTU, say ~3k) will require some of the data to be
754 * Ignoring multiple lanes,the estimated delay will be approximately equal to
756 * ( m_cbPendingUnreliable+m_cbPendingReliable ) /
757 * m_nSendRateBytesPerSecond
759 * plus or minus one MTU. It depends on how much time has elapsed since the
760 * last packet was put on the wire. For example, the queue might have *just*
761 * been emptied, and the last packet placed on the wire, and we are exactly
762 * up against the send rate limit. In that case we might need to wait for
763 * one packet's worth of time to elapse before we can send again. On the
764 * other extreme, the queue might have data in it waiting for Nagle. (This
765 * will always be less than one packet, because as soon as we have a complete
766 * packet we would send it.) In that case, we might be ready to send data
767 * now, and this value will be 0.
769 * This value is only valid if multiple lanes are not used. If multiple lanes
770 * are in use, then the queue time will be different for each lane, and you
771 * must use the value in SteamNetConnectionRealTimeLaneStatus_t.
773 * Nagle delay is ignored for the purposes of this calculation.
