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.

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 time being backwards-compatible with STP.
