4. Highlights Benefits of HIP for P2PSIP: Distinct design choices:
Supports mobility (i.e. connections can survive the IP-address exchange)
Has a ICE-like NAT traversal mechanism
Support for leap-of-fait type of security with self-signed certificates
Distinct design choices:
LOCSER: Not generic, HIP: Generic
Overlay routing is done above the HIP layer
No changes to HIP, just a BCP document
