Dear Andreas,

Thank you for your hint,

I noticed that inside the Packet class, the field "dest" is only an
integer, so packet can not keep a history of its whole routing path, and
therefore multi-hop routing is not possible in current version of gem5. (Is
this correct?)

Do you think if I add a data-structure such as stack to the Packet class, I
would be able to route back the response over multiple hops?
It might be a starting point for supporting connection of multiple
interconnects in gem5.

Best Regards,
