RDP was standardized in RFC 908 (1984) and later updated by RFC 1151, and saw niche use and was largely superseded by TCP for most bulk-transfer purposes.
IP Protocol Network Policy
IP protocol #27 - Reliable Data Protocol - is typically dropped by edge routers and firewalls. Advanced threat actors and malware families can use these non-standard IP protocol numbers for lateral movement (east-west communication) inside internal networks.
