A voyage around work

The first in a series looking at the experience of work in 2019.

To land your ideal job, the suggestion is first to find your passion. Indeed, one college in the US promises to guide its students to find their life purpose by teaching them three things: what they are good at, what they are passionate about, and what the world needs.

Assuming you are lucky enough to align all three elements, challenges are still likely. How do you maintain a work-life balance? And what happens over time when, despite having fulfilling, challenging work, part of your creative self remains untapped?

This has been the experience of Mark Seery (pictured below), who was a senior staff member at Juniper Networks, responsible for helping shape the networking company’s strategy.

Juniper bolsters its MX routers with packet processing ASIC 

Juniper Networks has developed its next-generation packet processor, a single-chip package that includes 3D-stacked high-bandwidth memory. The device’s first use will be to enhance three of Juniper’s flagship MX series edge routers. 

The company has also announced software for the 5G cellular standard that separates the control and user planes, known as CUPS, and two new MX-series platforms that will use the company’s universal chassis.

The company’s MX series edge routers were first introduced in 2007. “The MX is a platform that is at the heart of our service provider customers globally, as well as a number of our cloud provider and enterprise customers,” says Sally Bament, Juniper’s vice president of service provider marketing (pictured).       

The latest enhancements will provide the MX edge router customers with another decade of support to meet their evolving service requirements, says Bament.

Verizon, Ciena and Juniper trial 400 Gigabit Ethernet 

Verizon has sent a 400 Gigabit Ethernet signal over its network, carried using a 400-gigabit optical wavelength.

The trial’s goal was to demonstrate multi-vendor interoperability and in particular the interoperability of standardised 400 Gigabit Ethernet (GbE) client signals.

Glenn Wellbrock“[400GbE] Interoperability with the client side has been the long pole in the tent - and continues to be,” says Glenn Wellbrock, director, optical transport network - architecture, design and planning at Verizon. “This was trial equipment, not generally-available equipment.” 

It is only the emergence of standardised modules - in this case, an IEEE 400GbE client-side interface specification - that allows multi-vendor interoperability, he says.

Juniper Networks opens up the optical line system 

Juniper Networks has responded to the demands of the large-scale data centre players with an open optical line system architecture.

Donyel Jones-WilliamsThe system vendor has created software external to its switch, IP router and optical transport platforms that centrally controls the optical layer.

Juniper has also announced a reconfigurable optical add-drop multiplexer (ROADM) - the TCX1000 - that is Lumentum’s own white box ROADM design. Juniper will offer the Lumentum white box as its own, part of its optical product portfolio.

The open line system architecture, including the TCX1000, is also being pitched to communications service providers that want an optical line system and prefer to deal with a single vendor.

“Juniper plans to address the optical layer with a combination of software and open hardware in the common optical layer,” says Andrew Schmitt, founder and lead analyst at Cignal AI. “This is the solution it will bring to customers rather than partnering with an optical vendor, which Juniper has tried several times without great success.”

Telefónica tackles video growth with IP-MPLS network  

  • Telefónica’s video growth in one year has matched nine years of IP traffic growth 
  • Optical mesh network in Barcelona will use CDC-ROADMs and 200-gigabit coherent line cards 

Telefónica has started testing an optical mesh network in Barcelona, adding to its existing optical mesh deployment across Madrid. Both mesh networks are based on 200-gigabit optical channels and high-degree reconfigurable add-drop multiplexers (ROADMs) that are part of the optical infrastructure that underpins the operator’s nationwide IP-MPLS network that is now under construction.

Maria Antonia CrespoThe operator decided to become a video telco company in late 2014 to support video-on-demand and over-the-top streaming video services.

Telefónica realised its existing IP and aggregation networks would not be able to accommodate the video traffic growth and started developing its IP-MPLS network.

Juniper Networks to acquire Aurrion for $165 million

The announcement of the acquisition was low key. A CTO blog post and a statement that Juniper Networks had entered into an agreement to acquire Aurrion, the fabless silicon photonics start-up. No fee was mentioned.

However, in the company's US Securities and Exchange Commission filing, Juniper values the deal at approximately $165 million. "The Company believes the acquisition will help to fuel its long-term competitive advantage by enabling cost-effective, high-density, high-speed optical networks," it said. The deal is expected to be closed this quarter.

At first glance, Juniper is simply the latest in a series of systems vendors bringing silicon photonics in-house. Silicon photonics is a technology that allows photonic devices to be made on a silicon substrate, fabricated in a CMOS facility.

Colt's network transformation

Colt's technology and architecture specialist, Mirko Voltolini, talks to Gazettabyte about how the service provider has transformed its network from one based on custom platforms to an open, modular design.


It was obvious to Colt that something had to change. Its network architecture based on proprietary platforms running custom software was not sustainable; the highly customised network was cumbersome, resistant to change and expensive to run. The network also required a platform to be replaced -  or at least a new platform added alongside an existing one - every five to seven years.

Mirko Voltolini

"The cost of this approach is enormous," says Mirko Voltolini, vice president technology and architecture at Colt Technology Services. "Not just in money but the time it takes to roll out a new platform."

Instead, the service provider has sought a modular approach to network design using standardised platforms that are separated from each other. That way, a new platform with a better feature set or improved economics can be slotted in without impacted the other platforms. Colt calls its resulting network a modular multi-service platform (MSP).
