IPv6/IPv4 Coexistence - Goals
No disruption
- IPv6 and IPv4 Router + Hosts can interoperate
- No flag days
Incremental upgrade / Deployment
- IPv6 routers and hosts can be deployed in an Intranet in a highly diffused and incremental fashion
- Users will deploy at different rates
Specify mechanisms not policy
Low start-up costs
- Transition should be as easy as possible for end-users, system administrators, and network operators
API must support IPv4 and IPv6
Header translation will be needed
