Basic Concepts
This section describes the basic concepts of EDSG and the relationships between EDSG elements.
Service Group
A service group identifies a type of specific data traffic. It is used as a source or destination in a traffic rule and is referenced in an access control list (ACL).
EDSG Service Policy
As shown in Figure 4-1, EDSG service policies are
bound to service groups, which are used to identify service traffic.
Typically, a group of specific destination addresses is used as traffic
identification characteristics. EDSG service policies have the following
characteristics:
Each EDSG service policy contains rate limit and statistics at the forwarding layer, and authentication, accounting, and prepaid quota management at the service layer.
Each EDSG service is mapped to one service flow, and multiple EDSG services can be loaded for a user.
