Alcatel-Lucent has unveiled a new family of Internet core routers – the 7950 XRS (Extensible Routing System).
The flagship of the family, the 7950 XRS-40, supports 32 terabits per second (Tbps) capacity and 160 100Gigabit Ethernet ports in a single system, which is five times the density of today’s core routers. The 7950 XRS also slashes power consumption by more than 66 percent compared to typical core routers, says Alcatel-Lucent.
The 7950 XRS backplane and optical interconnect are designed to handle slot capacities of 2 Tbps, multi-chassis clustering that enables the system to scale up to 240 Tbps in the future, as well as support 400GE and 1 Terabit interfaces as they become available.
The 7950 XRS family consists of three routers:
- 7950 XRS-40 supports 32 Tbps of routing capacity, capable of supporting 160 100GE interfaces in a single core router. It is designed to accommodate up to 2 terabits per slot and is upgradeable to multi-chassis configurations to ensure continued growth as needed. It will be available in the first half of 2013.
- 7950 XRS-20 is a 16 Tbps core router that can deliver 80 100GE interfaces in a single rack (5x more than the current norm). It can be upgraded to 7950 XRS-40 and/or multi-chassis configurations as demand requires, and is designed to accommodate up to 2 terabits per slot. It will be available in the third quarter of 2012 and is currently in several trials.
- 7950 XRS-16c is a 6.4 Tbps core router, ideal for meeting core routing requirements of smaller points of presence (POPs)/nodes with maximum agility. It delivers up to 32 100GE interfaces and is designed to accommodate 1 terabit per slot. It will be available in the first half of 2013.
