1561: Use of ISO CLNP in TUBA Environments.

This memo specifies a profile of the ISO/IEC 8473 Connectionless-mode Network Layer Protocol (CLNP, [1]) for use in conjunction with RFC 1347, TCP/UDP over Bigger Addresses (TUBA, [2]). It describes the use of CLNP to provide the lower-level service expected by Transmission Control Protocol (TCP, [3]) and User Datagram Protocol (UDP, [4]). CLNP provides essentially the same datagram service as Internet Protocol (IP, [5]), but offers a means of conveying bigger network addresses (with additional structure, to aid routing).
