## Use-Case Guides

[WebRTC Latency Test: Measure P2P Round-Trip Time](https://capytoolkit.com/tools/network/p2p-tester/webrtc-latency-test/): Measure peer-to-peer WebRTC round-trip time between two browsers. Real latency over the actual network path: ISP, NAT, and router included.
[Check Your NAT Type for Gaming and Video Calls](https://capytoolkit.com/tools/network/p2p-tester/nat-type-checker/): Find your NAT type (Open, Moderate, or Strict) in the browser. Understand how your router affects WebRTC, gaming, and direct P2P connections.
[Browser Packet Loss Test: Measure P2P Drop Rate](https://capytoolkit.com/tools/network/p2p-tester/packet-loss-test/): Measure real peer-to-peer packet loss between two browsers over WebRTC. Identifies drops on the actual ISP path, not just to a server.
[Network Jitter Test: Measure Connection Stability](https://capytoolkit.com/tools/network/p2p-tester/network-jitter-test/): Measure peer-to-peer network jitter between two browsers. Quantify timing variation on the actual P2P path, not just to a server.
[Symmetric NAT and WebRTC: What Breaks and Why](https://capytoolkit.com/tools/network/p2p-tester/symmetric-nat-webrtc/): Understand why symmetric NAT blocks WebRTC direct connections and forces TURN relay routing. Diagnose and fix the ICE failure.
[Video Call Quality Test: Latency, Jitter, and Loss](https://capytoolkit.com/tools/network/p2p-tester/video-call-quality-test/): Test the three metrics that determine video call quality: peer-to-peer RTT, jitter, and packet loss, measured directly over WebRTC.
[Gaming P2P Latency Test: Measure Direct Connection Lag](https://capytoolkit.com/tools/network/p2p-tester/gaming-p2p-latency/): Measure peer-to-peer latency between two game clients over WebRTC. Identify whether lag comes from the ISP path, NAT type, or relay routing.
[Fix WebRTC Connection Failed: ICE Failure Explained](https://capytoolkit.com/tools/network/p2p-tester/webrtc-connection-failed/): Diagnose WebRTC ICE connection failures. Identify whether the cause is symmetric NAT, a missing TURN server, or firewall blocking, and learn the fix.
[VoIP Quality Test: Latency, Jitter, and Packet Loss](https://capytoolkit.com/tools/network/p2p-tester/voip-quality-test/): Test VoIP call quality metrics over a real P2P path. Measure RTT, jitter, and packet loss using WebRTC probe packets between two browsers.
[STUN Server Test: Discover Your Public IP and NAT](https://capytoolkit.com/tools/network/p2p-tester/stun-server-test/): Run a STUN server test to discover your public IP address and NAT type in the browser. No install needed; works on any WebRTC-capable browser.
[ICE Candidate Type: Host vs srflx vs Relay](https://capytoolkit.com/tools/network/p2p-tester/ice-candidate-type-checker/): Check your WebRTC ICE candidate type in the browser. Understand whether your connection uses direct host, reflexive (srflx), or relay routing.
[Network Stability Test: Measure Jitter and Loss Over Time](https://capytoolkit.com/tools/network/p2p-tester/network-stability-test/): Measure peer-to-peer network stability over a sustained WebRTC session. Track jitter and packet loss trends to identify intermittent congestion.

## P2P Network Tester Reference

[What Is WebRTC?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-webrtc): WebRTC (Web Real-Time Communication) is a browser API enabling direct peer-to-peer audio, video, and data without plugins or servers.
[What Is NAT (Network Address Translation)?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-nat): NAT maps private IP addresses to a public IP, allowing multiple devices to share one internet connection. Learn how NAT types affect WebRTC and P2P connections.
[What Is Network Jitter?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-jitter): Network jitter is the variation in packet arrival timing. Learn why jitter causes audio and video problems and how it is measured and reduced.
[What Is Packet Loss?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-packet-loss): Packet loss is the percentage of transmitted packets that never reach their destination. Learn what causes it and how it affects voice, video, and gaming.
[What Is ICE (Interactive Connectivity Establishment)?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-ice): ICE is the IETF protocol WebRTC uses to discover, prioritize, and check connectivity paths between two peers through NAT.
[What Is a STUN Server?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-stun): A STUN server helps WebRTC peers discover their public IP and NAT type. Learn how STUN works and why it is essential for peer-to-peer connections.
[What Is Round-Trip Time (RTT)?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-rtt): Round-trip time (RTT) is the elapsed time for a packet to travel from sender to receiver and back. Learn why RTT matters for WebRTC, VoIP, and gaming.
[What Is SDP (Session Description Protocol)?](https://capytoolkit.com/tools/network/p2p-tester/reference/#what-is-sdp): SDP describes WebRTC session parameters including ICE candidates, codecs, and DTLS fingerprints. Learn how SDP enables peer-to-peer connections.
