South Korea's lunar orbiter launches and phones home happily
Friday, 05 August 2022 16:31

South Korea's first lunar orbiter, which is about to test disruption-tolerant, network-based space communications, successfully made contact with its Australian ground station after launching on Thursday.

According to South Korea's Ministry of Science, Technology, Information and Communications, the Korea Pathfinder Lunar Orbiter's (KPLO) planned tests are a world first.

The orbiter carries the equipment for exploring Delay-Tolerant Networking (DTN), which addresses latency caused by long distances and other factors that can make network resources unavailable for significant periods of time. DTN adds a type of store-and-forward tech called "bundle protocol" to the networking stack, so that when latency or interruptions

Why you should start paying attention to CXL now
Thursday, 04 August 2022 23:45

After more than three years of development, compute express link (CXL) is nearly here. The long-awaited interconnect tech will make its debut alongside Intel's upcoming Sapphire Rapids and AMD's Genoa processor families.

This means there's a good chance the next server you buy will support the emerging interconnect tech. So what is it good for?

For now in its 1.1 iteration, the CXL conversation centers on memory expansion and tiered memory applications. Need more RAM than you've got DIMM slots? Just pop a CXL memory module into an empty PCIe 5.0 slot, and you're off to the races.

Yes, it'll

Fortinet's latest hyperscale kit packs 2.4Tbit/sec of firewall into a 4U chassis
Thursday, 04 August 2022 21:15

As port speeds creep ever higher to support larger hyperscale workloads and bandwidth-hungry 5G applications, Fortinet says its latest generation of firewalls should keep even the largest data flows safe from would-be attackers.

The vendor this week unveiled its FortiGate 4800F-series of appliances, which top out at 2.4Tbit/sec of raw capacity, which it claims is fastest in class. That translates to SSL inspection and IPS/IDS speeds of 55Gbit/sec and 70Gbit/sec respectively.

To achieve these levels of performance, Fortinet crammed 16 of its NP7 network-security ASICs into a 4U chassis packed full of 50Gbit, 200Gbit, and 400Gbit interfaces. Fortinet claims this

Strike days should serve as 'wake-up call' to BT's top brass, says union
Thursday, 04 August 2022 18:30

The two days of strike action by BT call center operators and engineers at the Openreach subsidiary should act as a “wake-up call” to the executive management team at the British telco but no further dates are yet scheduled.

On July 29 and August 1, tens of thousands of unionized workers at the former state owned business laid down their tools in protest over pay for the first nationwide industrial action at BT since 1987.

In a message sent to members, Dave Kerr, general secretary at the Communication Workers Union said the strike days represented its members “fighting back against

Linux may soon lose support for the DECnet protocol
Thursday, 04 August 2022 02:00

There's a proposal to remove the code for the DECnet networking protocol from the Linux kernel… but what was DECnet anyway?

Microsoft software engineer Stephen Hemminger has proposed removing the DECnet protocol handling code from the Linux kernel. The timing is ironic, as this comes just two weeks after VMS Software Inc  announced that OpenVMS 9.2 was really ready this time…

That announcement, of course, came some months after the first time it announced [PDF] version 9.2, as we covered in The Reg in May .

The last maintainer of the DECnet code was Red Hat's Christine Caulfield, who flagged
