Q
QCE
QCE is an acronym for QoS Control Entry. It describes QoS class
associated with a particular QCE ID.
There are six QCE frame types: Ethernet Type, VLAN, UDP/TCP Port,
DSCP, TOS, and Tag Priority. Frames can be classified by one of 4 different
QoS classes: "Low", "Normal", "Medium", and "High" for individual
application.
QCL
QCL is an acronym for QoS Control List. It is the list table of QCEs,
containing QoS control entries that classify to a specific QoS class on
specific traffic objects.
Each accessible traffic object contains an identifier to its QCL. The
privileges determine specific traffic object to specific QoS class.
QL
QL In SyncE this is the Quality Level of a given clock source. This is
received on a port in a SSM indicating the quality of the clock received in
the port.
QoS
QoS is an acronym for Quality of Service. It is a method to guarantee a
bandwidth relationship between individual applications or protocols.
A communications network transports a multitude of applications and data,
including high-quality video and delay-sensitive data such as real-time voice.
Networks must provide secure, predictable, measurable, and sometimes
guaranteed services.
Achieving the required QoS becomes the secret to a successful end-to-end
business solution. Therefore, QoS is the set of techniques to manage
network resources.
R
RARP
RARP is an acronym for Reverse Address Resolution Protocol. It is a
protocol that is used to obtain an IP address for a given hardware address,
such as an Ethernet address. RARP is the complement of ARP.
RADIUS
RADIUS is an acronym for Remote Authentication Dial In User Service. It is
a networking protocol that provides centralized access, authorization and
accounting management for people or computers to connect and use a
network service.
