P4 programming language gets folded into the Linux Foundation

The P4 Language Consortium (P4.org), creator of the P4 programming language,  will become a project of the Open Networking Foundation (ONF) and become part of the Linux Foundation portfolio.

P4 was designed to be target-independent (i.e. a program written in P4 could be compiled, without modification, to run on a variety of targets, such as ASICs, FPGAs, CPUs, NPUs, and GPUs), and protocol-independent (i.e. a P4 program can describe existing standard protocols, or be used to specify innovative, new, customized forwarding behaviors). P4 can be used for both programmable and fixed-function devices alike. For example, it is used to accurately capture the switch pipeline behavior under the Switch Abstraction Interface (SAI) APIs, used by the SONiC open-source switch OS. P4 is also used by the ONF Stratum project to describe forwarding behavior across a variety of fixed and programmable devices.

“A group of us decided on May 19, 2013 that we needed an industry-standard, open language for specifying forwarding behaviors,” said Nick McKeown, Professor of Computer Science at Stanford University, and P4 Board Member. “We created a language that students are studying in our universities, and using to prototype and publish new research ideas at the best networking conferences. Industry has adopted P4 to program devices and capture existing behaviors. In the future, we hope that Internet RFCs and IEEE Standards will include a clear, unambiguous P4 specification too, paving the way for interoperability by design.”

“SDN has transformed the networking industry and P4 takes SDN to the next level by bringing programmability to the forwarding plane,” said Guru Parulkar, Executive Director at Open Networking Foundation. “We are excited to have P4.org join ONF and are looking forward to seeing our synergy bring incredible benefits to the P4 and the larger SDN community.”

“Linux Foundation is thrilled to welcome the P4 community,” said Jim Zemlin, Executive Director at Linux Foundation. “Networking is a major focus at the foundation and the addition of the thriving P4 community combined with Linux Foundation Networking Projects in similar domains will drive innovation in networking to the next level.”

Verizon tests Cisco’s Hybrid Information-Centric Networking

Verizon completed a series of tests on Cisco's Hybrid Information-Centric Networking (ICN), which is described as an innovative approach to content-aware service offerings based on “named data” rather than location identifiers such as IP addresses.

Specifically, Verizon successfully demonstrated Cisco’s open-source ICN software and validated its benefits over standard TCP/IP solutions for optimized mobile video delivery in a lab at the Verizon Innovation Center in Waltham MA. The demonstrated benefits include key features of the ICN communication model – including dynamic adaptive streaming solutions and dynamic load balancing of media – which will lead to a better user experience. In the network, forwarding/caching strategies maximize traffic localization and bandwidth savings in backhaul/core via enhanced multicast.

“The Hybrid-ICN solution delivers all the benefits of ICN communication with minimal existing IP infrastructure upgrades required,” said Srini Kalapala, vice president, Technology Architecture and Strategy at Verizon. “By demonstrating the benefits of a virtualized Hybrid-ICN network at scale, we showcased how the technology can simplify the way users access content in a mobile environment and lead to a better user experience. We’re pleased with the results of our collaboration with Cisco and with the promise of the technology.”

“Cisco’s Hybrid-ICN solution provides secure content-intelligent transport for network service providers,” said Dave Ward, senior vice president, CTO of Engineering and Chief Architect at Cisco. “Through our co-development with Verizon, we found that H-ICN empowers the network edge with low latency caching and computing capabilities for the support of new revenue-generating applications such as enterprise multi-radio access, augmented and virtual reality, and IoT for 5G.”

Finisar develops Miniature Coherent Transmitter and Receiver Assembly

Finisar introduced the industry's smallest fully integrated coherent optics assembly, designed for coherent line cards or DCO (Digital Coherent Optics) transceivers.

Finisar's Integrated Tunable Transmitter and Receiver Assembly (ITTRA) will be marketed as a new product family for helping customers to accelerate their time to market and reduce program and development costs.  It provides the same functionality as a CFP2-ACO but is 70% smaller than the size of a CFP2 module. All key building blocks of an ACO interface (tunable laser, optical amplifier, modulators, drivers, coherent mixer, photodiode array, and TIAs) are incorporated in a single optical sub-assembly, which is combined with a miniature controller board that provides customers a standardized management interface.

Finisar said that because the ITTRA is a fully calibrated and tested assembly instead of a disaggregated set of components, it yields operational cost savings for the line card or module integrator because test times of the end product are greatly reduced.

"Customers that have previewed this product acknowledge the exceptional level of integration achieved in Finisar's ITTRA, and we have a tremendous amount of interest in this product due to its performance, compact footprint, and low power dissipation," said John DeMott, Senior Director of Marketing at Finisar. "A turn-key solution like the ITTRA, greatly reduces the development effort for the line card or module integrator, allowing them to rapidly respond to new market opportunities." The demonstration at OFC 2018 shows the 32Gbaud ITTRA transmitting and receiving data at 200 Gb/s using DP-16QAM modulation. The product will be sampling in the second quarter of 2018.

At OFC 2018, Finisar also demonstrated its WaveShaper A Series of Programmable Optical Processors with newly released WaveShaper App revision 1.3. This software supports arbitrary power splitting on up to 16 ports with ratios of up to 100 to 1. Finisar demonstrated a WaveShaper processor covering the extended C+L band with a total wavelength range larger than 100 nm. Arbitrary filtering of attenuation and phase is supported across the entire range.

Finisar debuts 400G QSFP-DD Active Optical Cable and Transceivers

Finisar introduced a 400G QSFP-DD LR8 and FR8 transceivers, a 400G QSFP-DD active optical cable, a 100G serial QSFP28 transceiver, and two 50G SFP56 transceivers.  The rollouts were featured in a series of demonstrations at OFC 2018.

The QSFP-DD (Quad Small Form Factor Pluggable Interface Double Density) module form factor provides an eight-lane electrical interface, compared to traditional single or four-lane interfaces, thereby increasing bandwidth, channel capacity and port density.

400G QSFP-DD LR8 and FR8 Transceivers
Finisar' 400G QSFP-DD LR8 transceiver uses 50G PAM4 technology. It offers a 10km reach over duplex single mode fiber (SMF). In addition to the 10km LR8 module, a 2km FR8 variant of this module will also be available from Finisar, primarily for intra-data center applications. Both the LR8 and FR8 modules leverage DML transmitter technology, providing a low power, low risk, cost-effective solution for 400G.

400G QSFP-DD Active Optical Cable
Finisar is introducing the industry's first 400G active optical cable (AOC) in the QSFP-DD form factor. It uses VCSEL technology to achieve the low power dissipation and low cost structure.

100G Serial QSFP28 FR Transceiver
Finisar is introducing a 100G serial FR transceiver in the popular QSFP28 form factor for inter-data center, transport and router applications with 2km reaches. While leveraging a standard 4x25G electrical interface, so that it plugs into standard QSFP28 slots, this module employs just one serial 100G PAM4 optical channel. Once deployed in sufficient volume, it is expected to replace existing 100G QSFP28 CWDM4 modules. Finisar also plans to introduce a 500m DR version of this module. Four of these FR or DR modules will be able to be used in a fan-out configuration with an IEEE standard 400G DR4 module, thus providing both 100G point-to-point and 100G-to-400G fan-out connectivity at 100G per lane. The module transmits data over 2km of SMF.

50G SFP56 SR and LR Transceivers
Finisar is also introducing the industry's first 50G SFP56 SR and LR transceivers, using serial PAM4 technology. Primary applications for these products include server-to-switch and switch-to-switch 50G Ethernet connections, and future 5G wireless applications.

During OFC, Finisar demonstrated the SFP56 SR module transmitting over 100 meters of OM4 multi-mode fiber (MMF), and the SFP56 LR module transmitting over 10km of SMF.

The modules use Finisar's in-house vertically integrated optics and ICs. They provide interoperability with previous generations of 25G SFP28 and 10G SFP+ optical transceivers. Both modules comply with the corresponding 50GBASE-R specifications as defined in the IEEE standards and offer 50G PAM4 electrical and optical interfaces.

"Today, we have established a number of industry first optical modules that will enable Finisar to maintain its leadership position for the next generation of products," said Rafik Ward, Senior Vice President, Global Marketing at Finisar. "Building upon 30 years of success, we are gearing up for a new era of optical interfaces that will be built on 50G and 100G PAM4 technology. This will enable us to deliver unprecedented bandwidth to customers in form factors that are backward compatible with industry established footprints.
