New 7nm routing chip churning 14.4 Terabits per Second

Broadcom launches router chip named Jericho2c+, featuring 14.4 terabits per second routing at a high power efficiency. The 7nm router chip enables a 36 Port 400GbE line-card with integrated security with only two chips saves footprint, complexity, power and costs compared to alternative solutions that require a far larger number of devices, as claimed by Broadcom.

Jericho2c+'s programmable pipe, large-scale forwarding databases and future-proofing matrix of programmable elements, provide a set of capabilities that addresses the most challenging routing requirements, says Broadcom. Jericho2c+ is also said to improve port density, increases subscribers scale, reduces power per bit, and reduces the total cost of ownership.

This chip solves the problem of higher power consumption with integrated line-rate MACSec on all network interfaces, making it the ideal solution for data center interconnect, metro and core switches.

"In the past, router vendors had to choose between a flexible pipe with feature concurrency versus power efficient high-bandwidth devices," said Bob Wheeler, principal analyst, The Linley Group. "Jericho2 disrupted the routing market by providing full routing capabilities without compromising performance. Jericho2c+ takes bandwidth, integration, and power efficiency to the next level, while adding line-rate security."
