NEC takes control of its OpenFlow controllers

ProgrammableFlow 5.1 to include uber-controller


NEC is prepping for this month's Open Networking Summit in Santa Clara with the pre-exhibition announcement of the latest addition to its software-defined networking (SDN) lineup.

Its contribution to the data centre infrastructure “mine's bigger” game is a new controller, the UNC (Unified Network Controller – apparently someone at NEC unearthed a 1990s “product marketing guidelines” manual from HP, in which sushi is “cold dead fish”).

Described as a “controller of controllers”, the UNC's key specs are that it will act as master for ten other NEC OpenFlow controllers (which could be in one data centre or across multiple sites); those downstream controllers can connect up to 2,000 switches, supporting 30,000 virtual tenant networks, 100,000 VLANs and ten million flows, NEC says.

Virtual networks can span multiple data centres, the company says, and the UNC should help make it easer to move VMs around so as to avoid putting too many of their loads in one place.

The company's OpenFlow controllers first shipped in 2011, at the time acclaimed as the first commercial OF controller implementation.

The UNC ships as part of V5.1 of the company's OpenFlow-based ProgrammableFlow Networking Suite, announced here. Its multi-site flow capability means it can help users move workloads between different sites, while controlling the WAN link traffic flows.

As well as redundancy, NEC has an eye to growing interest in moving loads between sites to get them as close to end users as possible (for example, in content distribution networks). ®

    Puny human brains baffled by K8s complexity, leading to blunder fears

    Kubernetes, despite being widely regarded as an important technology by IT leaders, continues to pose problems for those deploying it. And the problem, apparently, is us.

    The open source container orchestration software, being used or evaluated by 96 per cent of organizations surveyed [PDF] last year by the Cloud Native Computing Foundation, has a reputation for complexity.

    Witness the sarcasm: "Kubernetes is so easy to use that a company devoted solely to troubleshooting issues with it has raised $67 million," quipped Corey Quinn, chief cloud economist at IT consultancy The Duckbill Group, in a Twitter post on Monday referencing investment in a startup called Komodor. And the consequences of the software's complication can be seen in the difficulties reported by those using it.

    Phew!

    Google has quietly dropped its demand that users of its free G Suite legacy edition cough up to continue enjoying custom email domains and cloudy productivity tools.

    This story starts in 2006 with the launch of “Google Apps for Your Domain”, a bundle of services that included email, a calendar, Google Talk, and a website building tool. Beta users were offered the service at no cost, complete with the ability to use a custom domain if users let Google handle their MX record.

    The service evolved over the years and added more services, and in 2020 Google rebranded its online productivity offering as “Workspace”. Beta users got most of the updated offerings at no cost.
