How Google is speeding up the Internet

Engineers at Google have developed a new algorithm to speed up TCP, the main transport protocol for traffic on the internet, by optimizing the speed at which traffic is sent so it doesn’t clog up the available routes. They say their acceleration method, called bottleneck bandwidth and roundtrip (BBR) propagation time, measures the fastest way to send data across different routes and is able to more efficiently handle traffic when data routes become congested. Google is already using BBR to speed up its YouTube traffic, and last month the company made BBR available in its Google Cloud Platform. Google says implementing BBR sped up the already highly-optimized YouTube traffic by 4% on average, and as much as 14% in some countries.To read this article in full or to leave a comment, please click here

Advancing Privacy Protection with the GDPR

A game-changer

The road towards implementation of the new European GDPR (the General Data Protection Regulation) has been a long one, even though public awareness of its impact, especially outside of Europe, is only now really starting to take hold. This game-changing piece of EU legislation will require companies to fundamentally change how they process and use personal data (broadly defined) they receive from EU citizens, including through consent and data handling agreements with their customers, supply chains, and vendors. It will come into effect on 25th May, 2018, and will have tremendous reach, touching on all business sectors. More than that, the GDPR has extra-territorial scope and will apply to any business that processes the personal data of European users, irrespective of whether that business has any physical presence in the European Union.

The aim of the GDPR, which will replace the currently applicable European Data Protection Directive of 1995, is to both meet the challenges of globalization and address dynamic new products and services, while also trying to create a future-proof framework that will comfortably accommodate emerging technologies and scenarios, including the Internet of Things. It is also a response to Europeans’ growing concerns over the control and Continue reading

BrandPost: How to Know if An Active-Active Architecture Right for You

Software defined WANs (SD-WANs) have gained market momentum so quickly because their value proposition is multi-faceted. Some enterprises have looked to SD-WAN as a way to dramatically lower network transport costs, while others are building SD-WANs to automate network operations. One of the more common use-cases I have seen is to shift toward an “active-active” architecture.ACTIVE-ACTIVE WAN ARCHITECTUREHistorically, WANs are built on the concept of “active-passive”, where a branch can be connected using two or more links, but only the primary link is active and passing traffic.  In this scenario, the backup connection only becomes active in the event the primary connection fails. While this might seem sensible, it’s highly inefficient as enterprises are paying for far more bandwidth than they are actually leveraging. This inefficient architectural design is driving increased interest in active-active configurations.To read this article in full or to leave a comment, please click here

Cisco buys Springpath, adds fuel to the HCI fire

Last December, I wrote a post looking at “What to expect from Cisco in 2017”. It’s a foregone conclusion that Cisco will make a number of acquisitions every year, so that’s not hard to predict. The tough part is guessing the potential targets.One of the easier acquisitions to predict was Springpath because Cisco’s HyperFlex hyper-converged infrastructure (HCI) solution is an OEM of Springpath. The two companies have been working very closely since Springpath was founded in 2012. The product has been extremely well received by customers and channel partners, resulting in a little more than 1,800 customers to date. In fact, nearly customer and channel partner wanted the companies to join. To read this article in full or to leave a comment, please click here

SDN: Technology to cut costs, speed new services

Software defined networking is defined by a decoupling of the control and packet-forwarding planes in a network, an architecture that can slash operational costs and speed the time it takes to make changes or provision new services.Since all the intelligence resides in software – not baked into monolithic specialty hardware – customers can replace traditional switches with commodity devices to save on capital costs. SDN also makes it possible for the network to interface with applications directly via APIs to improve security and application performance.So what is SDN? Traditional networks are made up of devices with integrated control and data-forwarding planes so each box needs to be configured and managed independently. Because of this, even simple changes to the network can take weeks or even months to complete because the changes have to be made to each device. This was acceptable when network changes were typically made independently from business changes.To read this article in full or to leave a comment, please click here

Cisco brings its SDN to Amazon, Microsoft and Google’s public cloud

Today Cisco announced it is developing a way to integrate its software defined networking product named Application Centric Infrastructure (ACI) with public cloud infrastructure from Amazon Web Services, Microsoft Azure and Google Cloud Platform.By extending ACI from the data center to the public cloud, Cisco is making it easier for customers to manage a hybrid network that spans both environments. Having common network management across this hybrid environment allows customers to implement fine-grained security policies and manage applications across both, Cisco says.+MORE AT NETWORK WORLD: What SDN is and where it's going + To read this article in full or to leave a comment, please click here
