BrandPost: Measuring the edge: Finding success with edge deployments

Edge computing deployments are well underway as companies seek to better process the wealth of data being generated, for example, by Internet of Things (IoT) devices.So, what are the results? Plus, how can you ensure success with your own edge projects?Measurements of successThe use cases for edge computing deployments vary widely, as do the business drivers and, ultimately, the benefits.Whether they’re seeking improved network or application performance, real-time data analytics, a better customer experience, or other efficiencies, enterprises are accomplishing their goals. Based on two surveys — one by Automation World and another by Futurum Research — respondents have reported:To read this article in full, please click here

Interview with John Kindervag, the Godfather of Zero Trust Networking

Last month, I had the pleasure of spending a few minutes with John Kindervag, the industry-described “Godfather” and thought leader behind Zero Trust Networking. John developed these concepts during his tenure as Vice President and Principal Analyst at Forrester Research. Zero Trust, rooted in the principle of “never trust, always verify,” is primarily designed to …

Heavy Networking 446: How Open Systems Integrates Security And SD-WAN As A Service

Open Systems integrates security and SD-WAN as a service, including next-gen firewalls and Web gateways. They're the sponsor for today's Heavy Networking podcast. We discuss Open Systems' architecture, how it applies SD-WAN and security policies to traffic, and how Open Systems differentiates itself in this crowded market.

The post Heavy Networking 446: How Open Systems Integrates Security And SD-WAN As A Service appeared first on Packet Pushers.

Commentary: We’re stuck with 40 years old technology

One of my readers sent me this email after reading my Loop Avoidance in VXLAN Networks blog post:

Not much has changed really! It’s still a flood/learn bridged network, at least in parts. We count 2019 and talk a lot about “fabrics” but have 1980’s networks still.

The networking fundamentals haven’t changed in the last 40 years. We still use IP (sometimes with larger addresses and augmentations that make it harder to use and more vulnerable), stream-based transport protocol on top of that, leak addresses up and down the protocol stack, and rely on technology that was designed to run on 500 meters of thick yellow cable.

How to shop for enterprise firewalls

Firewalls have been around for years, but the technology keeps evolving as the threat landscape changes. Here are some tips about what to look for in a next-generation firewall (NGFW) that will satisfy business needs today and into the future.Don't trust firewall performance stats Understanding how a NGFW performs requires more than looking at a vendor’s specification or running a bit of traffic through it. Most firewalls will perform well when traffic loads are light. It’s important to see how a firewall responds at scale, particularly when encryption is turned on. Roughly 80% of traffic is encrypted today, and the ability to maintain performance levels with high volumes of encrypted traffic is critical.To read this article in full, please click here

Cisco goes all in on WiFi 6

Cisco has taken the wraps off a family of WiFi 6 access points, roaming technology and developer-community support all to make wireless a solid enterprise equal with the wired world.“Best-effort’ wireless for enterprise customers doesn’t cut it any more. There’s been a change in customer expectations that there will be an uninterrupted unplugged experience,” said Scott Harrell, senior vice president and general manager of enterprise networking at Cisco. “It is now a wired first world.” More about 802.11ax (Wi-Fi 6) Why 802.11ax is the next big thing in wireless FAQ: 802.11ax Wi-Fi Wi-Fi 6 (802.11ax) is coming to a router near you Wi-Fi 6 with OFDMA opens a world of new wireless possibilities 802.11ax preview: Access points and routers that support Wi-Fi 6 are on tap Bringing a wired first enterprise world together is one of the drivers behind a new family of WiFi 6-based access points (AP) for Cisco’s Catalyst and Meraki portfolios.  WiFi 6 (802.11ax) is designed for high-density public or private environments. But it also will be beneficial in internet of things (IoT) deployments, and in offices that use bandwidth-hogging applications like videoconferencing.To read this article in full, please click here

IDG Contributor Network: Robots extend the scope of IoT applications

Robots and IoT devices are similar in that they both rely on sensors to understand their environment, rapidly process large streams of data and decide how to respond.That’s where the similarities end. Most IoT applications handle well-defined tasks, whereas robots autonomously handle anticipated situations. Let’s consider both from six different vectors:1. Sensor IoT – Binary output from stationary sensor. “Is the door open or closed?” Robots – Complex output from multiple sensors. “What is in front of me? How do I navigate around it?” 2. Processing IoT – Simple data stream of signals handled with well-known programming methods. Robots – Large complex data streams handled by neural network computing. 3. Mobility IoT – Sensors are stationary and signal processing is done in the cloud. Robots – The sensor laden robot is mobile and signal processing is done locally and autonomously. 4. Response IoT – The action to take in response to a situation is well defined. Robots – Multiple actions could be taken in response to a situation. 5. Learning IoT – The application typically does not ‘evolve’ on its own and develop new features. Robots – Machine learning and other techniques are used to let Continue reading
