Networking devices provide an essential role in facilitating communication between computers and internet networks.

Introduction

For nearly three decades, PCI Express® (PCIe®) technology has served as the de facto high bandwidth, low latency interconnect. As the industry evolves to meet the needs of data-intensive applications, the PCIe specification has kept pace, enabling future innovation.

We are pleased to commence 2022 on a high note with the official release of the PCI Express® (PCIe®) 6.0 specification to members.

I am excited to report that PCI-SIG has released PCIe 6.0 specification, version 0.9 to our members. This is a major milestone in our continued effort to double the data rate of the PCI Express® specifications while maintaining backwards compatibility.

The upcoming PCIe® 6.0 specification introduces Flow Control Unit (FLIT) encoding, which enables the specification to provide low latency with high efficiency. FLIT mode is adopted for the PCIe 6.0 architecture because error correction needs to operate on fixed sized packets.

For almost two decades, the PCI Express^® (PCIe^®) architecture has offered low latency and high bandwidth in support of next generation systems.

We are starting 2020 with the release of version 0.5 of the PCI Express^® (PCIe^®) 6.0 specification incorporating the significant member feedback received on version 0.3.

PCI Express (PCIe^®) has been widely adopted in a number of applications that range from small, power-constrained IoT sensors and mobile devices to servers and networking and communications equipment.
