+ * first being that TCP is a stream oriented protocol that doesn't care much
+ * about your idea of a packet. The second reason being that TCP is a reliable
+ * transfer protocol with its own sophisticated ACK mechanism, making DCCs ACK
+ * mechanism look like a joke. For these reasons, DCCs requirements have
+ * (hopefully) been relaxed in most implementations and this implementation
+ * depends upon at least the following: The 1024 bytes need not be transferred
+ * at once, i.e. packets can be smaller. A second relaxation has apparently
+ * gotten the name "DCC SEND ahead" which basically means to not give a damn
+ * about those DCC ACKs and just send data as you please. This behaviour is
+ * enabled by default. Note that this also means that packets may be as large
+ * as the maximum segment size.
