Entries in FP3 (4)


The era of cloud-scale routeing 

Nokia's FP4 p-chip. The multi-chip module shows five packages: the p-chip die surrounded by four memory stacks. Each stack has five memory die. The p-chip and memory stacks are interconnected using an interposer.
  • Nokia has unveiled the FP4, a 2.4 terabit-per-second network processor that has 6x the throughput of its existing FP3. 
  • The FP4 is a four-IC chipset implemented using 16nm CMOS FinFET technology. Two of the four devices in the chipset are multi-chip modules.
  • The FP4 uses 56 gigabit-per-second serial-deserialiser (serdes) technology from Broadcom, implemented using PAM-4 modulation. It also supports terabit flows.
  • Nokia announced IP edge and core router platforms that will use the FP4, the largest configuration being a 0.58 petabit switching capacity router. 

Much can happen in an internet minute. In that time, 4.1 million YouTube videos are viewed, compared to 2.8 million views a minute only last year. Meanwhile, new internet uses continue to emerge. Take voice-activated devices, for example. Amazon ships 50 of its Echo devices every minute, almost one a second.

Given all that happens each minute, predicting where the internet will be in a decade’s time is challenging. But that is the task Alcatel-Lucent’s (now Nokia’s) chip designers set themselves in 2011 after the launch of its FP3 network processor chipset that powers its IP-router platforms.

Six years on and its successor - the FP4 - has just been announced. The FP4 is the industry’s first multi-terabit network processor that will be the mainstay of Nokia’s IP router platforms for years to come.

Alcatel-Lucent serves up x86-based IP edge routing

Alcatel-Lucent has re-architected its edge IP router functions - its service router operating system (SR OS) and applications - to run on Intel x86 instruction-set servers.

The company's Virtualized Service Router portfolio aims to reduce the time it takes operators to launch services and is the latest example of the industry trend of moving network functions from specialist equipment onto stackable servers, a development know as network function virtualisation (NFV).     

"It is taking IP routing and moving it into the cloud," says Manish Gulyani, vice president product marketing for Alcatel-Lucent's IP routing and transport business.

A Terabit network processor by 2015?

Given that 100 Gigabit merchant silicon network processors will appear this year only, it sounds premature to discuss Terabit devices. But Alcatel-Lucent's latest core router family uses the 400 Gigabit FP3 packet-processing chipset, and one Terabit is the next obvious development.

Network processors to support multiple 100 Gigabit flows

EZchip Semiconductor has disclosed the first 200 Gigabit-per-second network processor chip. The NP-5 will double the packet processing performance of the company’s existing NP-4 network processor and will sample at the end of 2012.

The NP-5 is noteworthy in integrating within a single chip a full-duplex 100 Gigabit-per-second (Gbps) packet processor and traffic manager. Such integration is important as line cards move from 100Gbps to 400Gbps densities, says Bob Wheeler, senior analyst at The Linley Group.
