+# Interfacing SCION with Existing Technologies
+The questions posed here are:
+
+* What existing protocols/solutions should be compatible with SCION simultanously?
+  How can ISPs offer traditional IP side by side with SCION.
+* Could a future evolution of the SCION specification better reuse existing technologies?
+  Referring to the possibility of slightly changing an existing technology (e.g. IPv6) to be used
+  as part of SCION, replacing part of the ad-hoc specification that we have for SCION.
+* What would be required effort to make them work?
+  Referring to the ranking according to different types of parties involved: ISPs, vendors,
+  application developers, etc.
+
+There are several possibilities of existing protocols/technologies/solutions that
+may work for this purpose:
+
+* IPv6 in the Data Plane. Use an IPv6 routing header as specified in 4.4. of {{RFC8200}}.
+* SCION IP Gateway. See section 3 of {{I-D.rustignoli-panrg-scion-components}}
+* SCION-IP translation {{SCIONIPTRLN}}
 * How can we interface with QUIC Multipath {{I-D.ietf-quic-multipath}}?
-* What are the implications for, and relations to the TAPS WG {{TAPS}}?
+* How can we interface with, and what is the relationship to TAPS {{TAPS}}?
