  • OpenDoc

    OpenDoc

    OpenDoc was a cross-platform software framework for compound documents, developed by Apple Computer. It was designed as an alternative to Microsoft’s Object Linking and Embedding (OLE) technology, which was proprietary and only available on the Windows platform.

  • Optical Burst Switching (OBS)

    Optical Burst Switching (OBS)

    Optical Burst Switching, also known as OBS, is a different optical networking scheme, which is better suited for the transmission of bursty traffic.

  • What is Quadrature Amplitude Modulation?

    What is Quadrature Amplitude Modulation?

    Quadrature amplitude modulation is a method of encoding digital data on an analog carrier signal, such as a radio frequency or an optical carrier.

  • What is the Slow Convergence Problem in routing protocols?

    What is the Slow Convergence Problem in routing protocols?

    The slow convergence problem refers to the time it takes for a routing protocol to converge, or to reach a stable state in which all routers in the network have the same view of the network topology and can accurately route packets to their destinations.

  • Web 3.0

  • Power Over Ethernet (PoE)

    Power Over Ethernet (PoE)

    Power over Ethernet (PoE) is an optional standard that provides direct current electrical power over Ethernet twisted-pair cabling. This makes it possible for an Ethernet switch port to provide both Ethernet data and the power needed to operate.

  • PoE Vendor Extensions to the Standard

    PoE Vendor Extensions to the Standard

    After 802.3at made it possible to provide roughly 30 watts over two pairs of wires, it was a relatively straightforward process to extend the standard to provide power over four pairs simultaneously.

  • PoE Port Management

    PoE Port Management

    To manage these power loads, vendors of switches typically program the switches to provision power one port at a time, this is PoE Port Management.

  • PoE and Cable Pairs

    PoE and Cable Pairs

    The PoE standard specifies the way that power is injected into the Ethernet cable pairs, and which pairs should be used.
