Comparing IP and CLNP: Local (Node) Multihoming
Another area where CLNP is a clear winner when compared to the TCP/IP stack is multi-homed nodes (nodes with multiple interfaces, not site multi-homing, where whole networks are connected to two upstream providers).
Multi-homed TCP/IP nodes must have multiple IP addresses because IP uses address interfaces. There is no well-defined procedure in TCP/IP for how a multi-homed node should behave. In the early days of TCP/IP, they tried to address that in RFC 1122 (Host Requirements RFC), but even then, there were two ideas about dealing with multiple interfaces: the strong and weak end system models (more details).
Worth Reading: Why Quantum Crypto is Bollocks
Today is a perfect day to point out the fantastic Why Quantum Cryptanalysis is Bollocks presentation (HT: A blog post by George Michaelson)
It’s a must-read, even if you’re absolutely uninterested in the topic. Just replace “Quantum mumbo-jumbo” with AI or SDN ;) Have fun!
