- The router would support 1Tbit/s per slot in the form of a card with ten 100Gbit/s ports. Whether this card would be available right away isn't clear. That would still fall short of the 12 100Gbit/s ports per card that Arista announced for its switches, but, depending on when the card arrives, it could be the best density for a core router. As a point of comparison, the Alcatel-Lucent 7950 Extensible Routing System got announced last year with a theoretical per-slot capacity of 1.6Tbit/s (800Gbit/s if you're not double-counting the traffic).
- It would double as an MPLS label-switched router, to provide the kind of Layer 2 "lean core" (Cisco's phrase) that some carriers are talking about. (See Verizon Builds an MPLS Metro with AlcaLu and Juniper Aims Big With 100G Optical.)
- It would be an ASIC-driven design, as usual. The network processor involved would carry 336 packet-processing cores on-chip and would handle both Ethernet processing and OTN framing.
