Mindmeld, According to Cisco, the GSR12000 architecture can be extended to Terabit speeds and is scheduled to be available by mid summer 2000. Of course, according to Juniper, the FPGA intensive architecture of the GSR is not scalable and Cisco must design new ASICs to achieve Terabit speeds meaning a delay until at least year end 2000 and probably 2001. Furthermore, Cisco is hard at work on a new carrier-class rewrite of IOS that also may or may not be ready. IMHO Cisco is likely to be late with its Terabit product, but the damage will be controlled by IBM-style FUD. Furthermore, I would not be surprised if Cisco introduces an interim souped up, subTerabit level GSR - I have been quite surprised at how much additional milage Cisco has been able to get out of the 7500 design. BTW Tony Li is gone, but his team remains - there is still alot of talent at Jnpr. Also: The Juniper M40 is not a Terabit class router either today, but it apparently is scalable upto about 1.4Tbps based on the ASIC and software design. No specifics on when the next version will be available, but I would guess 6 months or so.
