IPv6 for embedded products

IPv6 specification itself is generic, and broad-minded
Need tips to implement it into embedded products
Severe memory/CPU resource limitation

Example: path MTU discovery
Path MTU discovery and fragmentation is costly for embedded products
How we can avoid PMTUD? - always generate packets < 1280bytes
