[c-nsp] cisco and juniper - virtualization (sdr, psdn, lsys)

[Aaron Gould]

I understand that cisco vrf and juniper routing-instance are similar - both
separate routing tables

 

But on a lower level of virtualization, I know about cisco sdr (secure
domain router) and juniper logical system.which I thought were comparable,
UNTIL, I read about juniper psdn (protected system domains)

 

Are juniper psdn's more comparable to cisco sdr ? Or are juniper lsys's more
comparable to cisco sdr and juniper psdn is something different?

 

Someone please elaborate on these.
