[SCION] Some Questions for diploma Thesis (SCIONLab)

[Juan A. García-Pardo]

Hi Mauro,
Send me a direct email with your Matrix username (@user:server) so I can
add you to our Matrix SCION room.
By the way, your overview picture shows a peering link between ASes in two
different ISDs. I think that will not work, but we can talk about it in
Matrix.
Best regards,

Juan A.
