There are certain requirements regarding the flows associated with different CoS labels. For example, CoS labels H and M must be satisfied CBS MFS. Flows associated with CoS label L must have CBS > MFS or EBS MFS or both. Overall, the performance objectives specified by MEF [31] must apply to CoS FS. The CPOs for Carrier Ethernet (defined per performance tier) are given in Table 4.7. There are several defined performance metrics for the CoS IA [31]. For example, the IA requires support for at least one of the two defined delay parameters, one-way frame delay (FD) and one-way mean frame delay (MFD) [31]. Also, IA requires support for at least one of the two performance metrics on delay variation to be included in SLS: one-way inter-frame delay variation (IFDV) and one-way frame delay range (FDR). 4.5 End-to-End QoS Network Design Table 4.7 Carrier Ethernet CoS performance objectives (CPO) per PT for point-to-point EVC.
