    The traffic accepted by the NIC is controlled by an NDIS Miniport Driver [17] while various protocols, such as TCP/IP, are implemented by NDIS Protocol Drivers. [18] A single miniport may be associated with one or more protocols. This means that traffic coming into the miniport may be received in parallel by several protocol drivers.

    The PD shall never request more power than the physical 802.3af class. The PD shall never draw more than the maximum power advertised by the PSE. The PSE may deny any PD drawing more power than maximum it has allowed. The PSE shall not reduce power allocated to the PD that is in use. The PSE may request reduced power, via conservation mode.

    The xHCI is a radical break from the previous generations of USB host controller interface architectures (i.e. the Open Host Controller Interface (OHCI), the Universal Host Controller Interface (UHCI), and the Enhanced Host Controller Interface (EHCI)) on many counts.

  8. DOCSIS - Wikipedia

    en.wikipedia.org/wiki/DOCSIS

    The earlier BPI specification (ANSI/SCTE 22-2) had limited service protection because the underlying key management protocol did not authenticate the user's cable modem. Security in the DOCSIS network is vastly improved when only business critical communications are permitted, and end user communication to the network infrastructure is denied.
