  • Incremental SDN: Automating Network Device Configuration

    The definition of Software Defined Networking (SDN) continues to broaden, today including functions such as configuration automation and orchestration. While these tasks aren't strictly SDN, the fact is software is used to define some aspect of the network infrastructure in both cases, so vendors have stretched the definition of SDN to bring configuration automation and orchestration platforms into the mix. In fairness, the line gets blurry, as some modern orchestration systems use programmatic interfaces to provision the network instead of traditional configuration tools such as SSH or SNMP.

  • The promise of software defined networking

    If you aren't intimately familiar with software defined networking, don't fret. Only 10 per cent of 450 IT practitioners at a recent Network World event raised their hands when asked if they understand SDN. But if the emerging technology lives up to its promise to redefine networking as we know it, there is no time like the present to dig in and learn more.
