UDP does not handle forwarding requests. It is a connectionless protocol and does not provide any mechanisms for retransmission of lost or corrupted packets. Forwarding requests is typically handled by higher-level protocols or applications that use UDP as a transport layer protocol. For example, in a peer-to-peer file sharing application, each peer may use UDP to communicate with other peers and request file pieces. However, the actual forwarding of requests is handled by the application logic and may involve maintaining routing tables and sending packets to the appropriate peers.
