Barefoot's Tofino 2 chip delivers 12.8 Tbps switching for 32x400GE

Barefoot Networks is now sampling its Tofino 2 chip, the second generation of its P4-programmable Tofino Ethernet switch application-specific integrated circuit (ASIC) family.

Tofino 2 doubles the performance of the first generation Tofino chip, now delivering 12.8 Tbps of packet processing capacity for hyperscale data centers, cloud, enterprise and service provider networks. The device leverages 7nm process technology and is designed for full P4-programmability.

Tofino 2 highlights:

  • World’s first 7nm switch ASIC 
  • Supports up 32x400GE on a single chip.
  • Supports up to 256x10/25/50GE ports on a single chip.
  • Fully P4-programmable, enabling various deployment options, from a standard top-of-rack switch to a service provider router, or even a feature-rich switch appliance. 
  • Support for unrivaled table sizes for routing, tunnels, and access control lists (ACLs).
  • Support for Barefoot SPRINT™- Barefoot's enhanced version of the industry-standard In-band Network Telemetry (INT), providing fine-grained per-packet intelligent real-time visibility of network traffic. 
  • Leverages the growing industry-wide P4 Ecosystem supported by multiple switch and network interface controller (NIC) chips.
  • Modular architecture enabling rapid integration of 112G SerDes and silicon photonics.
“Until Tofino arrived in 2016, networking switch ASICs hadn’t changed much in 20 years; they all ran pretty much the same tired old features. Our industry is stuck in a dinosaur way of doing things, and it takes years to add new features,” said Nick McKeown, Co-Founder, and Chief Scientist at Barefoot Networks. “Thankfully, networking is changing. Tofino, the first chip based on the PISA architecture, moved protocols - old and new - up and out of hardware into software, where they evolve at the pace of software. Tofino started it, now Tofino 2, at twice the capacity and twice the resources, demonstrates there is no going back. Within five years all switches will be programmable. We believe programming your network should be as easy as programming your computer.”

Customers cited in the Barefoot press release include Goldman Sachs, Cisco, Alibaba Infrastructure Services, Tencent, Baidu, JD Cloud, and Ucloud.

ADVA transmits 300G wavelengths over trans-Atlantic distance

ADVA successfully transported 300 Gbps per wavelength over a 6,800 km fiber link. The demonstration, which was conducted in partnership with Acacia Communications, used ADVA's FSP 3000 CloudConnect TeraFlex platform.

The companies said the trial was the first in the industry to cover the trans-Atlantic distance with a fiber link typical of a cost-optimized submarine cable using 300 Gbps channels and a commercially available transponder with real-time digital signal processing (DSP). The demo also achieved the highest spectral efficiency for such a link carrying 300 Gbps per wavelength with 70GHz channel spacing.

ADVA’s FSP 3000 TeraFlex technology delivers 36 bidirectional 100 Gbps Ethernet services in a 1RU chassis and can transport up to 600 Gbps on a single wavelength. The modular FSP 3000 TeraFlex provides control over modulation format, symbol rate and channel spacing. The multi-haul solution maximizes the transmission capacity for any given fiber link, from access networks to links spanning submarine distances. As part of the ADVA FSP 3000 CloudConnect platform, it is completely open and programmable. It also delivers real-time telemetry streaming.

“This lab trial proves the power of our FSP 3000 TeraFlex™ to deliver scalable long-haul data transmission with the highest spectral density at the lowest cost-per-bit. It shows subsea and intercontinental network operators that our solution is an ideal choice for transporting enormous amounts of data with the utmost flexibility in symbol rate, modulation format, and channel spacing to maximize the capacity of any given network,” said Sorin Tibuleac, director, system architecture, R&D, ADVA. “We’ve already shown that our FSP 3000 TeraFlex™ supports the growing bandwidth needs of metro DCI infrastructure with successful 600Gbit/s trials. Now we’re proving what it can do over the world’s longest links."

“Triggered by increasing demand for data driven by cloud-based services, we’re seeing a significant expansion in long-haul and subsea cable networks. This trial broadens the horizons of what can be achieved over great distance in terms of capacity and modulation flexibility,” commented Christian Rasmussen, founder and VP, digital signal processing and optics, Acacia Communications.

Liquid Telecom to invest US$400 million in deal with Telecom Egypt
