This clause describes the architecture for support of Federation. To support Federation, EDGE-10 reference point is used between the ECSs to exchange ECS profile and EDN configuration information. If the ECSP is required to support service provisioning for a certain EAS whose information is not within the pre-configuration or OAM configuration, the ECS can use Edge repository functions as defined in clause 6.3.4 to support ECS discovery via ECS-ER.

Figure 6.2b.2-1 shows the architecture for support of federation. EDGE-10 reference point is introduced between the ECSs. ECSs interfacing over EDGE-10 reference point can be provided by different or the same ECSP. EDGE-10 interface is used for exchange of EDN configuration information. When one of the ECS is enhanced as an edge repository (ECS-ER) as defined in clause 6.3.4, making it the center of information for edge deployments, the ECS-ER receives information about edge deployments from other ECSs and stores it. In such deployments, EDGE-10 interface is used both for exchanging of ECS profile during ECS discovery and for exchanging EDN configuration information during service provisioning information retrieval.
