DQuic is an open-source QUIC implementation that extends the IETF-standardized protocol to support peer-to-peer communication and multipath transport, moving beyond traditional client-server architectures. It integrates NAT traversal, STUN, Relay, and signaling directly into the QUIC framework, enabling endpoints to establish direct connections without relying on external services.
I-server is a networking project that hides a server's identity from clients by using ICMP Echo Reflection and ICMP Destination Unreachable packets to relay communications indirectly through third-party servers, making it difficult to identify the actual server IP from network traffic analysis alone.
