Adding CoS and QoS
Explicit path set up can also associate specific resource requests with an FEC
Class of service
- Establish relative priority of one FEC over another – no absolute guarantees
Quality of service
- Specific guarantees on
- Bandwidth
- Delay
- Burst size etc
Primary objective is for MPLS to support the Diff-Serv QoS model (EF, AF1-12,etc)
CoS and QoS require explicit support in the data plane of the LSR’s
