Link-state tracking
Link-state tracking is used to provide interface linkage
scheme for specific application and it can extend range of link
backup. By monitoring uplinks and synchronizing downlinks,
add uplink and downlink interfaces to a link-state group.
Therefore, the fault of the upstream device can be informed to
the downstream device to trigger switching. Link-state
tracking can be used to prevent traffic loss due to failure in
sensing the uplink fault by the downstream device.
Loopback
It is the process that a signal is sent out and then sent back to
the sender. It is used to detect and analyze potential faults in a
ring network.
M
Mapping
A virtual data corresponding relationship
Multi-Mode Fiber
(MMF)
In this fiber, multi-mode optical signals are transmitted.
Multiplexing
Multiplexing is a method by which multiple analog message
signals or digital data streams are combined into one signal
over a shared medium. Generally, it is used to adapt multiple
lower-order path layer signals into a higher-order path or the
multiple higher-order path layer signals into a multiplex
section.
N
Node
A joint name for the subnet, NE, and symbol in a NMS
O
Optical channel
It refers to an independent channel for transmitting optical
information.
Optical power
The work done by light within a time unit
Units of optical power include mW and dBm, of which the
former is a linear unit and the latter is a logarithmic unit. The
relationship between the two units is:
P(dBm)=10Log(P(mW)/1mW)
Out-of-band network
management
Out-of-band network management refers that the NView
NNM system and the device communicate with each other
through a network, which is independent from the service
network.
