Key features include a dual-mode reliability mechanism: a standard reliable mode akin to TCP for general use,
Operation of TCPlla involves a modified handshake in which an option is exchanged to enable TCPllä. Data
Status and reception of TCPllä remain experimental and primarily in academic or research contexts. There is
