Akamai researchers say attackers are using an old OpenSSH vulnerability to target IoT devices and launch attacks.
Benefits of MPLS, Why MPLS is used on today networks and the Advantages of MPLS will be explained in this post. As an Encapsulation and VPN mechanism, MPLS brings many benefits to the IP networks. In this article most of them will be explained and design examples will be shared by referring more detailed articles on the website as […]

One of my readers sent me this question:
I often see designs involving several more than 2 DCs spread over different locations. I was actually wondering if that makes sense to bring high availability inside the DC while there's redundancy in place between the DCs. For example, is there a good reason to put a cluster of firewalls in a DC, when it is possible to quickly fail over to another available DC, as a redundant cluster increases costs, licenses and complexity.
Rule#1 of good engineering: Know Your Problem ;) In this particular case:
Read more ...BGP can be used as a PE-CE routing protocol in MPLS Layer 3 VPN. Also Service Providers run MP-BGP (Multiprotocol BGP) if they have MPLS Layer 3 VPN. In this article, MP-BGP will not be explained since it has been explained here earlier in detail. When BGP is used as a PE-CE routing protocol between […]

How Does Internet Work - We know what is networking
I sorry to put here something that is not really technical but with a blog with the name “howdoesinternetwork.com” it would be strange not to follow the story about the future of DNS governance giving the fact that DNS is a crutial part of internet functionality. You probably know how the internet works giving the fast that you are visiting a blog like this. Regardless of that, it will not hurt to explain in few words the importance of DNS (Domain Name System) for normal internet operation. Let’s surf to se how this works If you want to open this webpage
Although the timeline for reaching exascale class computing continues to stretch farther into the future, research teams are keeping an eye on what technologies will shape the machines of the post-exascale timeframe, which is in the 2022-2030 timeframe.
While many of the technologies stated in a comprehensive report about post-exascale supercomputers are already in process, albeit in various stages of development and adoption, there is little consensus about which mode of computing will lead us into an era of unprecedented data and simulation potential. Still, the effort on behalf of the EuroLab-4-HPC program is notable in its divisions between where …
Disruptive Technologies on the Post Exascale Horizon was written by Nicole Hemsoth at The Next Platform.
It is not news that offloading work from CPUs to GPUs can grant radical speedups, but what can come as a surprise is that scaling of these workloads doesn’t change just because they run faster. Moving beyond a single node means encountering a performance wall, that is, unless something can glue everything together so it can scale at will.
There are already technologies that can take multiple units of compute and have them share work from supercomputing and other areas (consider ScaleMP, for instance) but there are limitations to these approaches and thus far, they haven’t extended to meet the …
