Each accessible traffic object contains an identifier to its QCL. The privileges determine
specific traffic object to specific QoS class.
QL
QL In SyncE
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.
QoS class
Every incoming frame is classified to a QoS class, which is used throughout the device for
providing queuing, scheduling and congestion control guarantees to the frame according to
what was configured for that specific QoS class. There is a one to one mapping between QoS
class, queue and priority. A QoS class of 0 (zero) has the lowest priority.
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.
RDI
RDI is an acronym for Remote Defect Indication. It is a
MEP to indicate defect detected to the remote peer MEP
Router Port
A router port is a port on the Ethernet switch that leads switch towards the Layer 3 multicast
device.
RSTP
In 1998, the IEEE with document 802.1w introduced an evolution of STP: the Rapid Spanning
Tree Protocol, which provides for faster spanning tree convergence after a topology change.
Standard IEEE 802.1D-2004 now incorporates RSTP and obsoletes STP, while at the same
this is the Quality Level of a given clock source. This is received on a port in a
