Networking in 2015 - SDN and IPv6 | Part 1 After reading Sean Michael Kerner’s article in Enterprise Networking Planet earlier this month, I thought I’d add a few thoughts of my own to what he wrote.  He discusses SDN and IPv6.   Here’s my take on Software Defined Networking (SDN) in 2015: Given the ongoing hype and the range of benefits its proponents extol, I expect to see a continued increase in interest and evaluation of SDN.  However with the ongoing battle between the major SDN vendors (OpenFlow, Cisco ACI, VMware NSX, Contrail, etc.) and the fear of ‘backing the wrong horse’, the lack of proven, mature enterprise deployments and the management and monitoring difficulties associated with SDN (most NMS do not yet adequately support SDN) it is unlikely that wide-scale enterprise deployments of SDN will occur in 2015.  Whilst the perceived benefit of easing the...

Relief for Licensing Headaches By @MJannery [#SDN]

Licensing creates some major headaches for network managers, so I wasn’t surprised to read in a recent SearchNetworking article that “simplified licensing and billing” made the IT wish list for 2015. In the network management space, frustrations revolve around which licensing model to buy (e.g., by device, object, etc.), controlling the price of licenses, and finally, deploying and administering them. Entuity’s licensing approach addresses all three areas, emphasizing ease and customization. Here I’ll focus on deployment and administration. (You can read about our attitude towar... (more)

Software Defined Networking | Part 2 By @MJannery | @CloudExpo [#SDN #Cloud]

In our initial part in this blog series on SDN, I gave a quick background overview.  This part of the series will cover overlay SDN and underlay SDN. SDN technologies are broadly split into two fundamentally different paradigms - "overlay" SDN and "underlay" SDN.  With overlay SDN the SDN is implemented on top of an existing physical network.  With underlay SDN, the fabric of the underlying network is reconfigured to provide the paths required to provide the inter-endpoint SDN connectivity. Overlay SDN (e.g., VMware NSX and Contrail) use tunneling technologies such as VXLAN, STT ... (more)

MSP, or Bride-To-Be? By @MJannery | @CloudExpo #SDN

Let me explain by example. I was in South Africa visiting a large MSP. They were using Entuity to manage about 250 customers, and using a legacy framework vendor to manage 1: a German highway toll system company.  When they gave me a tour of the data center, they apologized that one of the two "big screens" in the NOC was showing the other vendor’s UI, rather than both having Entuity. But they had to keep an eye on the German customer's network too. I suggested that when a client decides to outsource to an MSP, it is a little like marriage.  After you say "I do", that is the last... (more)

Scaling with Distributed Pollers By @MJannery | @CloudExpo [#SDN #Cloud]

Enterprise in Disguise - Scaling with Distributed Pollers Not all network management solutions are alike, even though they may sound that way sometimes. A sure sign of a network management tool trying to pass itself off as an enterprise solution is when it implements distributed polling as a way to scale. These systems scale server capacity by adding distributed pollers, each sharing a portion of the overall CPU load. But any network monitoring architect can tell you that the bottleneck in infrastructure management is I/O to the database. Having multiple pollers simultaneously se... (more)
