Scaling QUIC Ingress: eBPF Socket Steering for HTTP/3 Connection Migration
IT InstaTunnel Team Published by our engineering team Quick answer Scaling HTTP/3 for High-Frequency Telemetry: eBPF Socket : MCP tunnel answer MCP tunneling gives a local MCP server a public HTTPS endpoint so AI tools can reach it during development without deploying the server first. What is MCP tunneling? MCP tunneling exposes a local Model Context Protocol server through a public endpoint so compatible AI tools can connect during development. When should I use InstaTunnel for MCP? Use InstaTunnel Pro when a local MCP endpoint needs public HTTPS access, stable routing, and stream-friendly tunnel behavior. When a remote edge node drops off the network for a few hundred milliseconds and comes back with a new IP address, a naive UDP proxy deployment will silently kill the session that was supposed to survive exactly that kind of disruption. This article looks at why that happens, and how eBPF-based socket steering at the kernel layer fixes it — using the real mechanisms Linux and...
