Routers

Juniper T4000• unveiled on Nov. 2010, not ship until the seco

nd half of 2011. • achieve twice the capacity of Cisco CRS-3• T4000 boasts capacity of 240Gbps per slot, or 4

Tbps per half-rack chassis • CRS-3 is a full-rack system with 4.48Tbps switch

ing capacity and 140Gbps per slot.• The main core router vendors are Cisco, Juni

per and Huawei, which between them account for 97% of total revenues, according to researchers at dell'Oro.

Juniper T4000• Smaller suppliers are trying to muscle in -

Brocade recently launched a high end Ethernet router, looking to expand from its enterprise base.

• But Cisco is complacent about its lead - it says the CRS-3 has 30 customers and $50m in booked revenue already.

Juniper T4000• the sweet spot for the T4000 may be mobile broadba

nd, especially as Cisco is likely to have upgraded the raw capacity of CRS-3 by the latter part of next year.

• routing closer to the subscriber in order to reduce backhaul requirements and metro routing where traffic does not leave the metrozone, will be the best bet for Juniper because of its new product's density, small footprint, and power requirements.

• Juniper insists the core is the key target, and will upgrade its TX Matrix Plus router interconnect so it can cluster four T4000s into one 16Tbps system. It will also allow carriers to cluster T4000s with current T1600 models.
