Term
Frame is used in reference to Ethernet, whereas packet is used
everywhere else.
The interface of the network controller that provides connectivity to
the external network infrastructure (port).
The interface of the network controller that provides connectivity to
the host OS running on the platform.
An intelligent entity comprising of HW/FW/SW, that resides within a
platform and is responsible for some or all management functions
associated with the platform (MC, service processor, etc.).
The component within a system that is responsible for providing
connectivity to the external Ethernet networked world.
The capability to allow remote media devices to appear as if they
were attached locally to the host.
The interface of the network controller that provides connectivity to a
management controller. It can be shorten to sideband interface as
appropriate in the context.
This refers to the entire physical interface, such as both the transmit
and receive interface between the management controller and the
network controller.
The term integrated controller refers to a network controller device
that supports two or more channels for NC-SI that share a common
NC-SI physical interface. For example, a network controller that has
two or more physical network ports and a single NC-SI bus
connection.
Multi-drop commonly refers to the case where multiple physical
communication devices share an electrically common bus and a single
device acts as the master of the bus and communicates with multiple
slave or target devices. In NC-SI, a management controller serves the
role as the master, and the network controllers are the target devices.
Point-to-point commonly refers to the case where only two physical
communication devices are interconnected via a physical
communication medium. The devices might be in a master/slave
relationship, or could be peers. In NC-SI, point-to-point operation
refers to the situation where only a single management controller and
single network controller package are used on the bus in a master/
slave relationship where the management controller is the master.
The control logic and data paths supporting NC-SI pass-through
operation on a single network interface (port). A network controller
that has multiple network interface ports can support an equivalent
number of NC-SI channels.
One or more NC-SI channels in a network controller that share a
common set of electrical buffers and common buffer control for the
NC-SI bus. Typically, there will be a single, logical NC-SI package for a
single physical network controller package (chip or module). However,
the specification allows a single physical chip or module to hold
multiple NC-SI logical packages.
Command, response and notification packets transmitted between MC
and NCs for the purpose of managing NC-SI.
Non-control packets passed between the external network and the MC
through the NC.
