• How SDN applications will change Layer 4-7 network services

  With SDN apps, engineers can deploy virtual appliances for Layer 4-7 network services that will be automated for more granular traffic management. Continue Reading

• OpenFlow configuration protocols: Understanding OF-Config and OVSDB

  OpenFlow directs network packet flows, but OpenFlow configuration protocols, OF-Config and OVSDB, form relationships between controllers and switches. Continue Reading

• Quiz: Managing the enterprise network

  This five question quiz accompanies Henry Svendblad's presentation series on managing the Enterprise Network. Test your retention of the materials Svendblad covered in his video series on enterprise network management. Continue Reading

• ISSU (in-service software upgrade)

  An ISSU (in-service software upgrade) is a technique for updating software on a network device without taking that device offline and thereby disrupting network services. Continue Reading

• How data center network fabric and SDN intersect

  SDN and data center network fabrics both enable converged networking and the ability to manage many switches as one. Where do the two intersect? Continue Reading

• Should I use the OpenFlow protocol in software-defined networks?

  The OpenFlow protocol isn't required for SDN, although the Open Network Foundation recommends it, which means networking vendors have options.Continue Reading

• Why do I need SDN technology?

  SDN is valuable, but uses extend to other parts of the network for increased network flexibility, dynamic traffic flow, decreased latency and QoS.Continue Reading

• Embrane

• Nicira Network Virtualization Platform (Nicira NVP)

  Nicira NVP is network virtualization software that manages an abstraction layer between end systems and the physical network infrastructure and enables the creation of independently operable virtual networks.Continue Reading

• NETCONF

  NETCONF is an IETF network management protocol that provides an administrator or network engineer with a secure way to configure a firewall, router, switch or other network device.Continue Reading

• Specialized SDN controllers: Are they necessary?

  An SDN controller, with or without OpenFlow, is not required for a software-defined network, and SDN architecture vendors take different approaches.Continue Reading
