According to some slides from a russian cisco connect event, the upcoming small-size
NCS 5501 and NCS 5502 will support 1M+ FIB and 50ms per port buffers.
Seem to be killer boxes. 48x100GE in 2RU with large FIB & buffers? Loving it already.
I wonder what prices will look like for those.
With Google Translate:
NCS 5501
• 800 Gbps @ 430 watts
• 40 x SFP + 1G / 10G + 4 x QSFP28 100G
• 1RU
• Intel Broadwell CPU 8Core @ 1.6GHz
• Dimensions WxDxH 444mm x551mm x 44mm
• External TCAM for more FIB, large buffers (~ 50 ms)
• 1-2M IPv4 FIB
• The same set of features as a modular
• FCS in IOS XR 6.1.1
NCS 5502
• 4.8 Tbps 100G @ ~ 2200 W
• 48 x QSFP 28 or QSFP + optics
• 2RU
• Intel Broadwell CPU 12Core @ 1.6GHz
• 8 ASIC packet processing
• Integrated FIA
• External FIB TCAM for more
• Large buffers (~ 50 ms)
• 1-2M IPv4 FIB
• The same set of features as a modular
• FCS in IOS XR 6.1.1
