IDG Contributor Network: Why companies are building application-specific edge delivery networks

There’s a trend emerging among many Internet-based companies that I find intriguing: they are creating their own edge delivery networks. Why? So that they can service their applications via these networks to enable greater resilience and performance for their users.Rather than the standard, garden-variety content delivery networks (CDNs), these edge delivery networks are tailored specifically for the applications they’ve been built to service. In some cases, this means the edge networks leverage highly specific connectivity to regional internet service providers or between application facilities; in other cases, it means placing specialized hardware tuned to specific needs of the application in delivery facilities around the world. And most importantly, these networks are operating application-specific software and configurations that are customized beyond what’s possible in general-purpose, shared networks.To read this article in full or to leave a comment, please click here

Mist uses AI to improve wireless network performance

A couple of months ago I was having dinner with a fairly well-known Silicon Valley executive who predicted that success for an IT vendor is based on two things: having lots of data and a robust artificial intelligence (AI) engine to discover new insights.If that is true, then Mist Systems seems to be in a strong position, as the company’s solutions were designed to use AI to solve some of the bigger challenges in Wi-Fi today.This week the wireless network company announced several new access points, as well as use cases, for its solution. Specifics are as follows:Introduction of client service-level expectations (SLE) In telecommunications, the concept of a service-level agreement (SLA) is a threshold that service providers are contracted to meet. The SLE from Mist is similar, although more proactive than a carrier’s SLA. With Mist, administrators can use data to set, monitor and enforce things that impact performance pre and post connection. Examples of this are time to connect, failed connection attempts, roaming, coverage, capacity and AP uptime. The SLEs can be monitored in real time and watched over time to provide up-to-the minute insight as to the health of Wi-Fi.To read this article Continue reading

True random numbers are here — what that means for data centers

For many decades, the term “random numbers” meant “pseudo-random numbers” to anyone who thought much about the issue and understood that computers simply were not equipped to produce anything that was truly random.Manufacturers did what they could, grabbing some signals from the likes of mouse movement, keyboard activity, system interrupts, and packet collisions just to get a modest sampling of random data to improve the security of their cryptographic processes.And the bad guys worked at breaking the encryption.We used longer keys and better algorithms.And the bad guys kept at it. And life went on.But something recently changed all that. No, not yesterday or last week. But it was only back in November of last year that something called the Entropy Engine won an Oscar of Innovation award for collaborators Los Alamos National Laboratory and Whitewood Security. This Entropy Engine is capable of delivering as much as 350 Mbps of true random numbers—sufficient to feed an entire data center with enough random data to dramatically improve all cryptographic processes.To read this article in full or to leave a comment, please click here

MPLS Scenario: Manually Configuring a BGP Router ID per VRF

Today I am going to talk about the configuration part of the BGP router id per VRF. In my example we took two different VRFs name NB and ttlbits and defined that VRF configurations.

The IP addresses are used here is for the demo purposes only and has no relevance with any of the enterprise network. These configurations are the demo configurations and will help you out for the configuration on your live network.

Below are the steps to configure the BGP router id per VRF. These steps are

• Defining VRF_ttlbits on the router
• Defining VRF_NB on the router
• Configuring Loopback with the IP address
• Configuring Ethernet interfaces with VRF
• Configuring VPNv4 and IPv4 address family

Fig 1.1- Basic Sample MPLS network topology

Below is the basic configuration of defining the VRF

Defining VRF ttlbits on the router

ip vrf vrf_ttlbits

Bringing behavioral game theory to security defenses

Kelly Shortridge and CSO senior writer Fahmida Y Rashid talk about using behavioral game theory to take advantage of hackers’ mistakes and manipulate the data they think they're receiving. People generally make decisions by either thinking ahead to figure out how people may act in a given situation, or by learning over time by observing what people are doing. Since attackers learn over time by collecting feedback, obfuscating what they get can really mess up what the attackers are able to learn.

Safeguarding power grids and other critical infrastructure from data leaks

CSO senior writer Steve Ragan talks with cybersecurity experts Krypt3ia and Kodor about how the pair seek out passwords, schematics and other sensitive documents on SCADA control system architectures that shouldn't be available online, passing along tips to federal authorities to combat real-world threats.

5 Wi-Fi analyzer and survey apps for Android

Wi-Fi networks have many variables and points of frustration. Different types of walls, materials and objects can impact the Wi-Fi signal in varying ways. Visualizing how the signals move about the area is difficult without the right tools. A simple Wi-Fi stumbler is great for quickly checking signal levels, but a map-based surveying tool helps you visualize the coverage, interference and performance much more easily. They allow you to load your floor plan map, walk the building to take measurements and then give you heatmaps of the signals and other data.Most Windows-based Wi-Fi surveying tools offer more features and functionality than Android-based tools provide, such as detecting noise levels and providing more heatmap visualizations. However, if you don’t require all the bells and whistles, using an app on an Android-based smartphone or tablet can lighten your load. (And in case you’re wondering why we're not discussing iOS apps, it’s because Apple won’t allow developers access to the Wi-Fi data, thus there can’t be any legit Wi-Fi surveying apps without jailbreaking the device.)To read this article in full or to leave a comment, please click here

Moving to a private cloud tips and considerations

There are a lot of reasons you may be thinking about moving to a private cloud environment. Perhaps you need more security, or maybe you feel the risks of public cloud have outweighed the benefits. But you’re still not certain that this version of web-scale networking is right for your company, and you’re wondering what’s involved in moving from a public cloud to a private one. Not surprisingly, there are several factors to consider when making the move from public to private clouds. Public clouds have their place, but there are many good reasons to switch. In this post we’ll covers some private cloud tips and considerations.

For an even deeper look at reasons you may want to switch to a private cloud, check out our education page, Private Cloud vs. Public Cloud.

Level set: Defining public, private and hybrid clouds

Private clouds take several different forms: semi-private cloud, virtual private cloud (hybrid), and fully private cloud. Each one has their advantages and disadvantages.

Semi-private clouds are similar to public clouds where the cloud is being hosted by a provider, but the access to the cloud is through private channels and not over the Internet. This reduces the problem of lag Continue reading
