It looks like you're right. This Trio chipset is a 30G chipset (full duplex)
and they have 4 of them per a 120G line card.
It makes sense, they have a 50G (full duplex) chipset on the T1600 core box
and then the 30G one for the MX. Of course they are totally different
chipsets, the former being not programmable and the latter being
But I was hoping that Juniper would come up with something better than just
a 30G chipset. EZChip NP4 will have better throughput than this.
