  • Network automation: How much is too much?

    How much network automation is too much? Interop panelists discuss how to find the right balance.

  • fog computing (fogging)

    Fog computing, also known as fogging, is a model in which data, processing and applications are concentrated in devices at the network edge rather than existing almost entirely in the cloud. That concentration means that data can be processed locally in smart devices rather than being sent to the cloud for processing

  • Networking engineer with a badge: IT where you least expect it

    When Fast Packet contributor Patrick Hubbard was pulled over for speeding, he got an IT tour he didn't expect.

  • Next-generation WLAN: How IEEE 802.11ac will change your network

    Just five years ago, no one would have described Wi-Fi as a primary access technology but now, as Wi-Fi and cellular architectures deliver security, reliability and robust throughput sufficient to delivery video and multimedia content, wireless LAN (WLAN) is a critical enterprise component. With the IEEE 802.11ac-2013 standard approved, WLAN data rates will soar to multiple-gigabit territory. This TechGuide focuses on the WLAN's evolution and why it will soon be a viable alternative to Ethernet.

  • New network architectures and traditional components: Why both are key

    The next stage in network architecture's evolution is upon us. An SDN future is certain. What's less clear is how quickly it will become the norm, and what network architects should do in the meantime to keep their systems healthy and operational.

  • SDN and NFV: Show me the business benefits

    SDN and NFV offer exciting new features, such as network automation, but are we able to prove the business benefits of this new technology?

  • Does SDN change everything in network architectures?

    Some experts predict that the network functions virtualization (NFV) and software-defined networking (SDN) mean that physical network equipment will soon be a thing of the past. Not true! While new virtual overlays are required as technology evolves, beneath them the physical network will persist. And that network will still need upgrades. The current evolution is unique in that core equipment upgrades must lend themselves to a next-generation network migration. Both the short- and long-term impact of SDN and NFV must be considered. So, too, the potential impact of WebRTC, the open source technology that promises to enable video, talk and text through Web browsers.

    This issue of Network Evolution will help network engineers assess the looming changes, determine how fast they might arrive and guide them in determining how to keep physical networks functioning in the meantime.

  • Five strategies to enhance cyber resilience

    Expert Uy Huynh details five security strategies to increase network recovery capabilities to keep your company working efficiently.

  • Your next switch: The data center's software-defined future

    The hardware-defined network is still around, but a software-defined switch is coming. Your next switch will include SDN features and will also need to be application-aware and integrated with robust security strategies. This handbook covers everything pros must know now about the software-defined switch of the near future.
