ValveSoftware/GameNetworkingSockets
GameNetworkingSockets
GameNetworkingSockets is a UDP networking library providing secure transport, peer discovery, and traffic control systems. It implements a networking layer for reliable and unreliable messaging over UDP, including tools for message fragmentation and reassembly.
The project features a peer-to-peer NAT traversal tool for establishing direct host-to-host connections by punching through firewalls and network address translation layers. It secures network traffic through encrypted transport and secure key exchange.
The library includes a traffic manager to organize data into prioritized lanes to prevent bandwidth bottlenecks. It also provides network condition simulation to test application stability by injecting artificial packet loss and latency.
Features
- UDP Transport Implementations - Implements a custom reliable transport protocol over UDP using sequence numbers and acknowledgments.
- NAT Traversal - Uses hole punching techniques to establish direct peer-to-peer connections through firewalls and NAT layers.
- Packet Fragmentation and Reassembly - Splits large data payloads into MTU-sized fragments and reconstructs them at the destination.
- Connectivity Establishment - Provides the mechanisms required to discover and link two hosts directly using signaling services.
- Peer-to-Peer Networking - Enables direct client-to-client data exchange by bypassing central servers via NAT traversal.
- Peer Discovery - Implements mechanisms for locating peers and establishing connections through signaling to bypass NAT and firewalls.
- Bandwidth Management - Controls network traffic and data transfer rates through prioritized lanes to ensure critical game updates arrive first.
- Data Transmission Reliability - Allows configurable reliability over UDP to ensure critical packets arrive in order while minimizing latency for others.
- Network Traffic Prioritization - Organizes network data into prioritized lanes with assigned weights to prevent bandwidth bottlenecks.
- Network Traffic Managers - Manages and optimizes data flow by controlling message priorities and bandwidth lanes.
- Traffic Lane Management - Implements a traffic manager that organizes data into prioritized lanes to prevent bandwidth bottlenecks.
- Network Encryption - Secures peer-to-peer network traffic using cryptographic protocols and secure key exchange.
- Symmetric Encryption - Secures network traffic using a shared secret key for symmetric encryption and decryption of packets.
- Traffic Encryption - Secures real-time communication streams using encryption to prevent interception of multiplayer data.
- Artificial Latency Injection - Provides tools to inject intentional delays and packet loss into the network stack to test application resilience.
- Game Networking Libraries - Reliable transport layer for game network traffic.
- Networking and Utilities - UDP-based networking with encryption.
- Networking Libraries - Reliable UDP networking library.
