Facebook to Roll Out Fizz Library

This library accelerates the deployment of TLS 1.3 over the Internet
08 August 2018   118

Facebook introduced a library called Fizz, specially released for the recent update of TLS under the number 1.3. Fizz is a library that accelerates the deployment of TLS 1.3 over the Internet and increases the speed and security of applications and services.


  • Asynchronous I / O supported by default
  • Improved collection / spread of input / output required from copies of data.
  • Delays and loadings of service processors are reduced, which process trillions of requests per day.
  • Data is divided into "pieces" and encrypted.

Fizz and TLS 1.3 are globally applied in mobile Proxygen applications, in load balancers, in internal services and the QUIC library, mvfst. Currently, Facebook protects more than 50% of its traffic using Transport Layer Security. Applications that use Fizz perform fewer memory and copy allocations.

In TLS 1.3, the concept of "early data" (zero data, or data from 0-RTT) was introduced, which helped to reduce the waiting time. According to ITEF, it does this without waiting for the TLS acknowledgment. However, this concept can be unsafe, so Fizz includes an API that helps to get rid of shortcomings.

In addition, Fizz provides two types of APIs that can handle the rejection of "early data": transparently or allowing the application to modify the information sent repeatedly.

Nvidia to Open MDL SDK Source Code

As reported, this set of tools integrates the precise look and feel of real-world materials into rendering applications

NVIDIA opened the source code of the Material Definition Language SDK. This tool kit is designed for transferring material parameters to any application for drawing 3D graphics. The tools will allow developers to use more applications for rendering and transfer projects to the Android and iOS platforms.

As an example, the company introduced fabric materials created in Allegorithmic Substance Designer. They can be saved in the library and quickly transferred to the Adobe Dimension CC application. The tools were also introduced into Unreal Studio 4.20 from Epic Games, designed to import 3D models into the Unreal Engine.

Being able to use a single material definition, like NVIDIA’s MDL, across multiple applications and render engines is a huge benefit to the end-user. Now that we’ve added MDL support to Unreal Studio, our enterprise customers can see their material representations converted to real time in Unreal Engine without baking every parameter. This means their creative intent can be carried to new forms of expression.

The tool kit also contains components for loading, checking and editing material parameters and converting them into PTX and LLVM-IR formats. Get more info at GitHub
