Cisco upgrades one IoT platform and announces another

Following Cisco's launch last week of its Digital Network Architecture (DNA), which delivers intent-based networking solutions and services, this week’s Cisco Live event in Las Vegas was highly focused on networking. Only a few announcements were made, but the Internet of Things (IoT) made the cut.Cisco’s approach to IoT has been difficult to grasp because it crosses so many divisions. Its largest IoT unit, Cisco Jasper, is exclusively focused on cellular-connected devices.To read this article in full or to leave a comment, please click here

Cisco Vs Ruckus Wireless Systems

There is always a great tussle between Cisco and Ruckus on the wireless upfront where both the vendors are working hard to grip the market with the features they are providing in their wireless domain. Today I am going to talk about the head to head discussion of Cisco and Ruckus, Although  there are lot of point which i am not going to cover here in this discussion.

Ruckus Wireless:
Ruckus wireless controllers address deployments of any size i.e. from a very small Field Sales Office to a Managed Service Provider solution. Clustered SCG 200s offer one of the highest scalability levels and are available in an appliance form factor as well as a virtual controller. EMS functions are built-in and integration via REST API is supported.

Full range of wireless controllers scaling from the entry level ZoneDirector 1200 which supports up to 75 AP’s, all the way up to the SmartCellTM Gateway controller which, with available clustering support, is capable of managing tens of thousands of AP’s and providing access for hundreds of thousands of mobile devices 

Virtual SmartZone
High Scale (vSZ-H) - up to10,000 APs, up to 100,000 clients
vSZ-H cluster of 4 - up to 30,000 Continue reading

New Petyawrap Ransomware Attack Again Highlights Critical Need For Security Processes

Whenever there's a new attack on a global scale, the world trusts the Internet a little less. Today we are concerned with the many reports about this new ransomware attack called "Petyawrap", "Petrwrap" or an older name of "Petya."

The sad fact is: this new attack exploits the same vulnerabilities in Windows systems as last month's WannaCry attack. 

Fixes have been available for most Windows systems since March 2017!

The same tips Niel Harper provided last month to protect against ransomware also apply here.

Patching Not Enough to Stop Petya

Voluminous amounts of information have already been disseminated regarding the “Petya” (or is it “NotPetya”? [1]) ransomware that hit the Ukraine hard [2] along with organizations such as “the American pharmaceutical giant Merck, the Danish shipping company AP Moller-Maersk, the British advertising firm WPP, Saint-Gobain […]

What Cisco’s new programmable switches mean for you

To help ring in the 2017 New Year, CNN wanted to do a live shot from a Royal Caribbean cruise ship, but had an issue: “They were concerned about being out at sea, would they have the ability to live-stream?” says Royal Caribbean’s CIO Mike Giresi.The answer was yes, and the live-shot went off without a hitch, in part because the ship’s Cisco network gear was programmable to prioritize the video trafficAs an early implementer, Royal Caribbean has found benefits from regarding Cisco’s programmable infrastructure as a flexible asset that can be driven by software. “There are huge advantages to looking at the network as a software layer,” Giresi says. “It gives us the ability to create products, drive an experience and deliver services that are integrated with the infrastructure.”To read this article in full or to leave a comment, please click here

Giving Out Grades For Exascale Efforts

Just by being the chief architect of the IBM’s BlueGene massively parallel supercomputer, which was built as part of a protein folding simulation grand challenge effort undertaken by IBM in the late 1990s, Al Gara would be someone whom the HPC community would listen to whenever he spoke. But Gara is now an Intel Fellow and also chief exascale architect at Intel, which has emerged as the second dominant supplier of supercomputer architectures alongside Big Blue’s OpenPower partnership with founding members Nvidia, Mellanox Technologies, and Google.

It may seem ironic that Gara did not stay around IBM to help this …

Worth Reading: High performance computing poised for change

There is a lot of change coming down the pike in the high performance computing arena, but it has not happened as yet and that is reflected in the current Top 500 rankings of supercomputers in the world. But the June 2017 list gives us a glimpse into the future, which we think will be as diverse and contentious from an architectural standpoint as in the past. —The Next Platform

Epyc win for AMD in the server security battle

While everyone is talking about the impressive performance potential and scale of AMD’s new Epyc server chips, overlooked in all the hoopla are the security features of the chip that may prove just as appealing.To start off, there is the tag team of Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV). Secure Memory Encryption allows for full encryption of data stored in DRAM, and SEV allows individual virtual machines to be assigned a unique cryptographic key, thus isolating them from each other as well as the OS hypervisor and administrator layer. These functions are based on a hardware security processor attached to the memory controller with a 128-bit AES encryption engine.To read this article in full or to leave a comment, please click here

DOE taps 6 firms for exascale computing research

The Department of Energy has awarded six tech firms a total of $258 million in funding for research and development into exascale computing. The move comes as the U.S. is falling behind in the world of top supercomputers.Energy Secretary Rick Perry announced that AMD, Cray, Hewlett Packard Enterprise, IBM, Intel and Nvidia will receive financial support from the Department of Energy over the course of a three-year period. The funding will finance research and development in three main areas: hardware technology, software technology and application development.Each company will provide 40 percent of the overall project cost in addition to the government funding. The plan is for one of those companies to be able to deliver an exascale-capable supercomputer by 2021. It’s part of the DOE’s Exascale Computing Project (ECP), which in turn is part of its new PathForward program, designed to accelerate the research necessary to deploy the nation’s first exascale supercomputers.To read this article in full or to leave a comment, please click here

On the ‘net: Interview on my network career

I was recently interviewed for a new network career site—

I started out building small networks on a lot of different technologies in the USAF, primarily Banyan Vines and Novell Netware, over Token Bus, Thicknet, and other technologies. We implemented a fiber backbone, and I helped replace the old physical switch telephone system main frame with a modern (at that time) SS7 based design. After this, I worked for a small Value Added Reseller around New York City, and then the ASME as a network administrator, then at BASF in the Advanced Technology Group. At this point my wife and I moved to Raleigh, and I started at Cisco TAC in the hardware team. From there I moved to the Routing Protocols team, then Global Escalation, and then into engineering in various roles around Cisco IOS Software and XR. After Cisco, I moved to Verisign Labs, where I primarily focused on security in a more research oriented role, then to Ericsson, working on IPOS, and now LinkedIn.

This looks like a great resource, worth following.
