# Transparent CoAP Services to IoT Endpoints through ICN Operator Networks +
## 4 Design and Implementation
### Response Processing
In addition, we demonstrate how CoAP traffic over an ICN network can unleash the full potential of CoAP, shifting both overhead and complexity from the (constrained) endpoints to the ICN network. In the case of CoAP observe, our approach aggregates the requests for the same resource and reduces the state management of the CoAP server. Furthermore, our approach also reduces the communication overhead. In the case of CoAP group communication, CoAP server does not need to implement IP multicast. In addition, no modification to DNS is required. Therefore, the resource-constrained IoT device does not need to allocate more resources for a DNS client implementation and IP multicast. Our next steps will be the development of an efficient consistency model in the case of the exceptional situation where the client and the server become out of sync due to the latency between the change of the resource state and update notification.
