5 Reasons To Move To An SD-WAN
Network World, March 21st, 2016

"The enterprise WAN has transitioned from dedicated TDM circuits with Frame Relay and ATM, to Packet-over-SONET and MPLS, and now to Ethernet-access services. However, two things have remained constant, WAN bandwidth is still expensive and provisioning WAN services can take a long time.

In addition, WANs have challenges with backup link utilization, security of remote sites, traffic engineering, Quality of Service (QoS), touchless provisioning, and traffic visibility. These issues and many business drivers are causing companies to re-evaluate their WAN design and deployment and look for opportunities for improvement.

Software-Defined WANs (SD-WAN) offer many advantages that make them compelling..."

Draw Up A Data Center Network Diagram You'll Actually Use
SearchDataCenter, March 24th, 2016

"Creating a data center network diagram is time-consuming but necessary work. Keep the scope narrow and know the priorities of your diagram to save time and energy.

Ask any network engineer what their least favorite task is, and most will refer to documentation. Documentation, particularly the data center network diagram, is often hard to create and, many times, even harder to maintain..."

    Managing The Software-Defined Wan
    Network World, March 22th, 2016

    "In previous articles I discussed how SD-WAN is an attractive step forward from simple IPsec VPNs as well as multi-vendor, multi-technology hybrid WANs, driving new functionality and quality levels into these networks. One important question is how next-generation WANs are managed - and by whom..."

        SDNs Come To The Branch Office, With Risks
        CIO, March 24th, 2016

        "Looking to save on networking costs, some CIOs are extending SDN capabilities to the WANs that connect remote offices. The challenge is that the fledgling SD-WAN market is unpredictable and driven largely by startups.

        Companies have been implementing software-defined networking (SDN) in an effort to make their networks more responsive to cloud services that require flexibility to accommodate scaling traffic loads. Now CIOs hoping to shave dollars off of their costly networking bills are looking to extend SDN capabilities to their wide area networks (WANs)..."

        Why Network Disaggregation Isn't For The Enterprise
        NetworkComputing, March 21st, 2016

        "There's a lot of talk today in the industry about network disaggregation. Internet giants like Facebook say it provides the flexibility that traditional networking equipment doesn't. Networking vendors like Dell and Juniper are jumping on the disaggregation bandwagon, saying they want to provide their customers with more choice.

        But I'm not going to beat around the bush: Despite what you've been told and sold, there is no compelling case to migrate to a disaggregated network in the enterprise..."
