Table 19 Mapping applications to service classes: example
8.2.6 Provisioning Service Class Definitions to slaves
As detailed in 0, nodes that wish to request a resource reservation through the Connection Admission Control
procedure must make a reference to the requested service class. As a matter of fact, it is necessary for the slaves to
have an idea of the service class definitions. The description of the available service classes will be obtained
through the Autoconfiguration process.
8.3 CONGESTION MANAGEMENT
The mission of CM is to manage the accepted connections in congested networks (due to a sudden drop in the
channel quality, for example). There are two possible policies that can be configured in the system:
• Fair Congestion Management Policy (FCMP): all traffic flows are treated equally. Therefore, if the
traffic scheduler cannot meet the bandwidth and latency requirements from users, it will decrease the
performance of all active flows equally until new bandwidth and latency definitions can be supported.
