Qos is a set of requirements that a network must meet to ensure a service level for each type of data. Qos (Quality of service) refers to capability of the network to provide better service for allowing the traffic to flow with special requirements.
There are two types of Qos Services:
Qos Compliant
Qos Non-Compliant
All the services created from the TJ5500 are Qos Compliant and the services which does not have proper Qos configurations associated are discovered in the TJ5500 as Qos Non-Compliant Services.
Following are the parameters in Qos Domain:
CIR: The Committed Information Rate is the guaranteed bandwidth for traffic arriving at or departing from the interface under normal line conditions. CIR is applicable for Ingress only.
PIR: Peak Information Rate specifies the maximum rate over the CIR at which the traffic is allowed into the network (ingress).
CBS: Committed Burst Size is the number of bytes allowed for incoming packets to burst above the committed information rate.
PBS: Peak Burst Rate is the number of bytes allowed for the incoming packets to burst above the peak information rate.
CIR guaranteed service: CIR Guaranteed services are all the services that are in Qos Domain and are Qos Compliant and contains TCProfiles with non zero CIR.
Best Effort Service: A service that makes no guarantee regarding the speed (bandwidth) with which the data will be transmitted to the recipient is a best effort service. It has the least priority traffic and a CIR=0 value.
NOTE: Within TJ5500, Qos supports a single COS per UNI and a flat Qos.
Services in MPLS-TP and .1q/.1ad mode both supports Qos.
