Managing wireless networks: How to address the key challenges

One challenge in managing wireless networks is that the tools and tech are changing rapidly. Here’s what network pros need to know now.

  • Mbps (megabits per second)

    Megabits per second (Mbps) are a unit of measurement for bandwidth and throughput on a network. Each megabit is equal to 1 million bits.

  • ARPANET

    ARPANET was the network that became the basis for the Internet. Based on a concept first published in 1967, ARPANET was developed under the direction of the U.S. Advanced Research Projects Agency (ARPA). In 1969, the idea became a modest reality with the interconnection of four university computers.

  • subnet mask (subnetting)

    A subnet mask is a 32- or 128-bit number that segments an existing IP address in a TCP/IP network and divides that address into discrete network and host addresses.

  • 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.
