Is Broadcom’s chip powering Juniper’s Stratus?

Briefing:  Data centre switching

Part 1: Single-layer switch architectures

Juniper Networks’ Stratus switch architecture, designed for next-generation data centres, is several months away from trials. First detailed in 2009, Stratus is being engineered as a single-layer switch with an architecture that will scale to support tens of thousands of 10 Gigabit-per-second (Gbps) ports.

Stratus will be in customer trials in early 2011.

Still some way to go

Briefing: Dynamic optical networking 

Part 1: The vision .... back in 2000

I came across this article (below) on the intelligent all-optical network. I wrote it in 2000 while working at the EMAP magazine, Communications Week International, later to become Total Telecom.

What is striking is just how much of the vision of a dynamic photonic layer is still to be realised.  Back then it had also been discussed for over a decade. And bandwidth management, like in 2000, is still largely at the electrical layer.

And yet much progress has been made in networking technology. But the way the network has evolved means that a more flexible photonic layer, while wanted by operators, is only one aspect of the network optimisation they seek to reduce the cost of transporting bits.

Differentiation in a market that demands sameness

Transceiver feature: Part 2

At first sight, optical transceiver vendors have little scope for product differentiation. Modules are defined through a multi-source agreement (MSA) and used to transport specified protocols over predefined distances.
