  • adaptive routing (dynamic routing)

    Adaptive routing, also called dynamic routing, is a process for determining the optimal path a data packet should follow through a network to arrive at a specific destination. Adaptive routing can be compared to a commuter taking a different route to work after learning that traffic on his usual route is backed up.

  • Internet of Things (IoT)

    The Internet of Things (IoT) is an environment in which objects, animals or people are assigned unique identifiers and given the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

  • leaf-spine (leaf-spine architecture)

    Leaf-spine is a two-layer data center network topology that's useful for data centers that experience more east-west network traffic than north-south traffic. The topology is composed of leaf switches (to which servers and storage connect) and spine switches (to which leaf switches connect). Leaf switches mesh into the spine, forming the access layer that delivers network connection points for servers.
