Overview Get/put & DHT maintenance Key-based routing LOCSER: SIP method Key-based routing SIP’s body with well-defined XML Setting up connections, mobility, NAT traversal, … HIP HIP’s NAT traversal (based on ICE) IPv4/v6 LOCSER + HIP

Example: Session Establishment C D LOCSER With ICE-like NAT traversal support (might be relayed) RR Existing connections HIP New connection (might be UDP enc.) SIP Media LOCSER + HIP

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 LOCSER + HIP
