Hi Paul,

The current text is clear about the Service Index but is it mandatory to include it in the header? Wouldn't this information be available locally in the service nodes?

The text explain that SI allows to detect loops, but isn't the loop detected too late in the service chain? Wouldn't be optimal to detect the loop earlier?

BTW, what is the behavior when several SFs are embedded in the same node (which information is used to direct the traffic to the appropriate SF)?

Thank you.

Cheers,
Med
