- A UE (not shown in the figure) sends a DNS request via the 5G user plane, which is detected by the Local DNS (LDNS) at the Edge GW.
- A new offloading rule is injected to the Edge Connector by the Edge GW.
- AF function hosted on the Edge Connector invokes the TrafficInfluence API, offered by the 5G CP.
- A DNS response is composed and sent by the LDNS, which includes an IP pointing to an Edge server.
- 5G CP configures the 5G UP with standardized 5G signaling related to offloading.
- Traffic from the UE is offloaded to the Edge server.
Setup guide
- Step 1, deploy edge GW and on-board iPerf (server) following the steps described in Installation Documentation.
Step 2, run ngc/start.sh to launch the 5G CP (NEF), Edge GW+server and AF. A DNS request will be sent hereafter.
Step 23, run ngc/test/Post.sh to start traffic offloading or ngc/test/Delete.sh to stop offloading.
