+@node Sync
+@unnumbered Sync protocol
+
+So-called sync protocol is used in current TCP daemon's implementation.
+It is aimed to be very simple and effective. It is used over reliable
+transport like TCP connections.
+
+It must be effective both on single-duplex and full-duplex links (for
+example satellites have very high throughput, but high-delay links).
+Acknowledging of each received packet, like
+@url{https://en.wikipedia.org/wiki/XMODEM, XMODEM} does, causes
+unacceptable performance degradation.
