Subject: [mpls] Dataplane implications of MPLS encryption

Hi,

I would appreciate thoughts form those of you that work in the dataplane.

What are the consequences of our proposals in
http://datatracker.ietf.org/doc/draft-farrelll-mpls-opportunistic-encrypt/ for
the dataplane?

Questions include:
- whether we could encrypt and decrypt using existing hardware and at line speed
- whether inserting two labels and a control word would be practical (this
happens
  at LSP ingress where other labels are also added)
- whether stripping labels and moving on to the real LSP work at the egress is
   practical

Ultimately, the consideration is whether the benefit of this approach justifies
the cost.

Thanks,
Adrian
