The flow ordering refers to that network bandwidth resources are scientifically and reasonably distributed and used through various strategies or methods, and the important distribution principle is that important tasks, important users and important user services can preferentially occupy the bandwidth resources, and the indexes of time delay, jitter, packet loss, throughput and the like are optimized as far as possible, so that high-quality transmission service is obtained as far as possible.

(1) Basic strategy for mapping service type and guarantee type
The principles are that delay sensitive and jitter sensitive traffic types try to use high priority PHB behavior to reduce queuing time in the routing switch device, and packet loss sensitive and low throughput traffic types try to use lowest drop precedence selected PHB behavior to reduce strategic packet loss due to queuing. The basic mapping relationship between the service type and the provisioning type is shown in table 2. One PHB value and one DSCP value can meet the requirement, and certainly, two columns can be adopted according to the requirement, namely one column is the PHB value, and the other column is the DSCP value.
TABLE 2 service type and Provisioning type proposed mapping relationship
(2) The service type and the guarantee type map the dynamic adjustment policy, see fig. 2.
When the network has the guarantee quality reduction, the service type and the guarantee type mapping are dynamically adjusted according to the following criteria.
1) The service sensitive to time delay and jitter is transversely adjusted, and the forwarding success rate is reduced by improving the discarding probability;
2) and for the service types sensitive to the throughput, longitudinal adjustment is carried out, and the forwarding priority is reduced.

where the bandwidth requirement is the minimum bandwidth required.
