What makes for a successful protocol ?

What makes for a successful protocol ? Which protocol is successful and why ?   Have you ever been asked these questions  ? As an engineer you cannot say I believe Protocol X is successful or Protocol Y is not.   There is nothing like ‘ I believe ‘. There should always a science behind […]

Worth Reading: Making providers responsible for content

When online content hosts face a risk of litigation over user-generated content, they will respond with overbroad censorship measures that limit individuals’ rights to post and access lawful, constitutionally protected speech. This is true whether the litigation risk comes from the government (as it would under the proposed online censorship bill we’re fighting in Germany) or from private actors. —CDT

The Memory Scalability At The Heart Of The Machine

Much has been made of the ability of The Machine, the system with the novel silicon photonics interconnect and massively scalable shared memory pool being developed by Hewlett Packard Enterprise, to already address more main memory at once across many compute elements than many big iron NUMA servers. With the latest prototype, which was unveiled last month, the company was able to address a whopping 160 TB of DDR4 memory.

This is a considerable feat, but HPE has the ability to significantly expand the memory addressability of the platform, using both standard DRAM memory and as lower cost memories such …

American HPC Vendors Get Government Boost for Exascale R&D

The US Department of Energy – and the hardware vendors it partners with – are set to enliven the exascale effort with nearly a half billion dollars in research, development, and deployment investments.  The push is led by the DoE’s Exascale Computing Project and its extended PathForward program, which was announced today.

The future of exascale computing in the United States has been subjected to several changes—some public, some still in question (although we received a bit more clarification and we will get to in a moment). The timeline for delivering an exascale capability system has also shifted, with most …

IDG Contributor Network: When SD-WAN is more than SD-WAN

As the SD-WAN market has matured, one thing has become very clear: SD-WAN will not exist on its own. The technology is merging with other networking technologies, ultimately becoming a feature of a much larger bundle. While it may be too early to say what this “new thing” will be, the rough contours are emerging.Predominantly, we’re seeing security and SD-WANs merge. Just consider some of the activity: Velocloud recently announced its SD-WAN Security Technology Partner Program to integrate with other security vendor’s products. Viptela (soon to be Cisco), Silver Peak, Velocloud and others have long (well, long in the SD-WAN sense) touted integration with security vendors using service chaining. Cato Networks built its own integrated security and networking stack in the cloud. Masergy bundles SD-WAN (Silver Peak and its own technology) with third-party security services in the cloud. But what’s missing in many of these integrated offerings is the completeness of the edge solution. Companies need more than just an SD-WAN in branch offices. They need firewall, IPS, anti-malware, URL filtering and anti-virus for security. Internally, networking calls for Active Directory, DHCP, DNS, and print services. Externally, the edge may need WAN optimization, bandwidth management, QOS, traffic balancing, Continue reading

Aryaka brings benefits of software defined to remote and mobile workers

It seems over the past few years the world has gone software defined crazy. We have software-defined networks, security, data centers, WANs, storage and almost anything else one can think of. However, the one area that seems to have been forgotten about is the remote and mobile worker, as the benefits of software-defined haven’t reached the billions of employees that work from their homes, road, hotels, airports and coffee shops. Considering the primary value proposition of most software-defined things is to improve application performance, it seems odd that no vendor has found a way to bring these benefits to an audience that comprises nearly 40 percent of the workforce today.To read this article in full or to leave a comment, please click here

Hyperscale data centers are pushing the limits in the Gigabit Ethernet switching market

For the first time since their debut on the market in the mid-2000s, 10 Gigabit Ethernet switches are set to lose share in the networking industry this year as service providers and hyperscale customers continue to adopt faster bandwidth 40 and 100 GbE switches, according to data from research firm IDC.IDC estimates that last year 10 GbE revenues stood at $6.15 billion, up from $5.44 billion in 2015. This year, IDC predicts 10 GbE switching revenues will fall to $5.94 billion.+MORE AT NETWORK WORLD: Nokia rolls out its first 'petabit-class' router | SD-WAN, what it is and why you'll use it one day +To read this article in full or to leave a comment, please click here

Worth Reading: Liqid’s Composable System

Hardware is, by its very nature, physical and therefore, unlike software or virtual hardware and software routines encoded by FPGAs, it is the one thing that cannot be easily changed. The dream of composable systems, which we have discussed in the past, is something that has been swirling around in the heads of system architects for more than a decade, and we are without question getting closer to realizing the dream of making the components of systems and the clusters that are created from them programmable like software. —The Next Platform
