The Programmable Switch Era Is Here… At Last!

7th September 2018

Twenty years after the first network processors were launched, we are now moving toward the fully programmable data plane, with network operator virtualization efforts driving that trend. Most physical networking systems are being replaced by virtual network functions (VNFs) running on servers at the core and edge of the network. These servers have general-purpose processors […]

Virtualizing the Customer Premises

4th May 2018

Universal CPE (uCPE) solutions enable a new approach in which remotely provisioned virtual functions provide key network functionality and bring the benefits of virtualization to enterprise networks. A growing number of service providers are deploying uCPE platforms that support one or more virtual network functions (VNFs) for WAN connectivity (including SD-WAN), security, routing, switching and […]

Competition Heats Up for SDN/NFV Processing

16th February 2018

The shift to application and network virtualization by operators and service providers requires a new generation of multicore processors that are being introduced by many vendors. Cloud services are being delivered from hyper-scale data centers and through edge networks where support for virtual applications and virtualized networks requires servers with multicore processors that have many […]

Why Gfast Is About to Come of Age

18th January 2018

The latest Gfast chipsets, supporting Amendment 3 functionality, are offering a mature solution for gigabit broadband that is re-igniting the copper-versus-fiber debate. Since the first Gfast chipsets were introduced in 2014, vendors have worked with network operators and system developers to run trials and experiment with higher performance, longer reach and support for coax. The […]

Ubiquitous SDN Acceleration Is Coming

15 November 2017

Smart network interface cards (NICs) with high-level programming are enabling the step up in application and virtualization performance that is needed to deliver on the promise of software-defined networking (SDN). By using smart NICs in every server, operators can ensure that network virtualization, load balancing and other low-level functions are offloaded from the server CPUs, […]

Switching Redefined for the Virtual Network

January 13, 2017

The shift to cloud services and virtual networks has made data center switches — and the switch devices used in them — key to delivering maximum network performance and service flexibility. Maximum network performance requires low latency switches with 25Gbit/s serial interfaces and 25GE and 100GE ports. Maximum service flexibility requires switches with support for […]
