When digital transformation is the goal, network renovation isn’t good enough
Thursday, 25 November 2021 19:30

Paid Feature Networks are supposed to make the world smaller. But in many ways, the traditional MPLS-based enterprise network created a galaxy of atomised, walled-off worlds.

This was fine when the applications and data most users needed for their day-to-day work lived inside their organisation’s network – as indeed were all, or nearly all, of the users. If that meant that staff working from home (or just in a smaller, branch office), were stuck with broadband and a VPN, well so be it.

But cloud-based services and applications are a fundamental part of the “digital transformation” that most organisations are

SmartNICs, IPUs, DPUs de-hyped: Why and how cloud giants are offloading work from server CPUs
Thursday, 25 November 2021 08:09

Systems Approach The recent announcements from Intel about Infrastructure Processing Units (IPUs) have prompted us to revisit the topic of how functionality is partitioned in a computing system.

As we noted in an earlier piece, The Accidental SmartNIC , there is at least thirty years’ history of trying to decide how much one should offload from a general purpose CPU to a more specialized NIC, and an equally long tussle between more highly specialized offload engines versus more general-purpose ones.

The IPU represents just the latest entry in a long series of general-purpose offload engines, and we’re now seeing quite

European carriers push for more OpenRAN support... but it might not end in a win
Wednesday, 24 November 2021 22:44

Analysis Hot on the heels of the UK government enshrining in law the power to strip out Huawei, five European carriers have banded together to ask European policymakers to push the development of open radio access network (OpenRAN) .

The operators – Deutsche Telekom, Orange, Telecom Italia (TIM), Telefónica, and Vodafone – published a report, "Building an OpenRAN system for Europe" [ PDF ], asking the EU to throw money and support at whitebox mobile infrastructure.

This is almost certainly in the hopes the (ideally) cheaper, interoperable kit will help the carriers' own bottom lines, but also to regain some
