The T4000 is due to ship in the second half of 2011, and will ultimately have multi-chassis capacity, just like the T1600 and T640, though that capability is not being officially announced just yet.
Why this matters
Carriers claim they're desperate to start deploying 100Gbit/s Ethernet ports, and the T4000 gives Juniper a core-network blueprint for transporting all those big Ethernet feeds. (See Verizon Does 100GigE in Europe and EENY 2010: Carrier Wants Cheap 100GigE Now Please.)
The T4000 also lets Juniper continue to claim a leg up on Cisco Systems Inc. (Nasdaq: CSCO) in the ongoing core-router wars. For example, its capacity of 240 Gbit/s per slot (slightly less than what Juniper had announced in February) outdoes Cisco's CRS-3, which has only 140 Gbit/s per slot. Undoubtedly, Alcatel-Lucent (NYSE: ALU) and Brocade Communications Systems Inc. (Nasdaq: BRCD) will still claim they can best Juniper in different ways -- Brocade, for instance, recently claimed 960 Gbit/s per slot on its MLXe -- but Juniper's main talking point remains its comparisons against Cisco. (See Juniper Upgrades the Core, Cisco Boosts the Core With CRS-3, and 100G Watch: Brocade Goes Big.)
