Luigi,
What about this protocol stack for LISP within TCMTF?
(to be seen in Courier letters)
TCP/IP UDP/IP RTP/UDP/IP
\ | /
\ | / ------------------------------
\ | /
Nothing or ROHC or ECRTP or IPHC header compressing layer
|
| ------------------------------
|
PPPMUX or other mux protocols multiplexing layer
/ | \
/ | \ ------------------------------
/ LISP \
/ | \
GRE or L2TP UDP \ tunneling layer
| | MPLS
| | ------------------------------
IP IP
I dont know if LISP could be included into TCMTF draft. What do you think?
Should it be defined inside the LISP WG?
We have to talk about that LISP signaling which could be used in TCMTF, as
you say.
Thanks,
Jose
