Hi, Joe
Thanks. So it is can be learnt that GRE,Mini Encapsulation seem also
can be discussed here, right?
We intend to include broader discussion of other encapsulations in future versions; this was intended to be an initial attempt, and omissions were not intentional.
We've already received suggestions to include GRE. Can you please provide info on Mini Encapsulation, though?
Note that we've also had a suggestion to include MPLS. MPLS is more like a conventional L2 layer, which not only encapsulates and decapsulates, but also adds new hop-by-hop forwarding. I think it's important to distinguish tunneling from L2 or other conventional protocol layering, and I believe this is easy as follows:
tunnels:
- encaps/decaps of new headers at the endpoints
- NO new mechanism between the endpoints
other protocol layering
- encaps/decaps of new headers at the endpoints
- new mechanism between the endpoints that may or may
not rewrite thes headers
