• Path Computation Element primer: Are PCE and SDN connected?

  Is there a role for Path Computation Element -- a seven-year old IETF protocol that separates the control plane from the head-end router -- in SDN? Continue Reading

• In the SDN WAN: Network programmability, provisioning and high availability

  The SDN WAN's network programmability and automated provisioning addresses the demands placed on the wide area network by the cloud, SaaS and BYOD. Continue Reading

• network hypervisor

  A network hypervisor is a program that provides an abstraction layer for network hardware.  Network hypervisors allow network engineers to create virtual networks that are completely decoupled and independent from the underlying physical network. Continue Reading

• 10 gigabit Ethernet (10 GbE)

  10 gigabit Ethernet is a telecommunication technology that offers data speeds up to 10 billion bits per second. It differs from traditional Ethernet in that it is a full-duplex protocol and does not require Carrier Sense Multiple Access/Collision ... Continue Reading

• programmable network (PN)

  A programmable network is one in which the behavior of network devices and flow control is handled by software that operates independently from network hardware. Continue Reading
