QUIC¶

QUIC is a data channel type in GOST. The implementation of QUIC depends on the quic-go/quic-go library.

TLS Certificate Configuration

For TLS configuration, please refer to TLS configuration。

Usage¶

CLIFile (YAML)

gost -L http+quic://:8443

services:
- name: service-0
  addr: ":8443"
  handler:
    type: http
  listener:
    type: quic

Options¶

Keep-Alive¶

The client or server can enable keep-alive through keepalive option, and set the interval for sending heartbeat packets through ttl option.

CLIFile (YAML)

gost -L http://:8080 -F "quic://:8443?keepalive=true&ttl=10s"

services:
- name: service-0
  addr: :8080
  handler:
    type: http
    chain: chain-0
  listener:
    type: tcp
chains:
- name: chain-0
  hops:
  - name: hop-0
    nodes:
    - name: node-0
      addr: :8443
      connector:
        type: http
      dialer:
        type: quic
        metadata:
          keepalive: true
          ttl: 10s

Proxy¶

QUIC tunnel can be used in combination with various proxy protocols.

HTTP Over QUIC¶

CLIFile (YAML)

gost -L http+quic://:8443

services:
- name: service-0
  addr: :8443
  handler:
    type: http
  listener:
    type: quic

QUIC and HTTP3

HTTP-over-QUIC is not HTTP3, so you cannot use an HTTP-over-QUIC service as an HTTP3 service.

SOCKS5 Over QUIC¶

CLIFile (YAML)

gost -L socks5+quic://:8443

services:
- name: service-0
  addr: :8443
  handler:
    type: socks5
  listener:
    type: quic

Relay Over QUIC¶

CLIFile (YAML)

gost -L relay+quic://:8443

services:
- name: service-0
  addr: :8443
  handler:
    type: relay
  listener:
    type: quic

Port Forwarding¶

QUIC tunnel can also be used as port forwarding.

Server

CLIFile (YAML)

gost -L quic://:8443/:1080 -L socks5://:1080

is equivalent to

gost -L forward+quic://:8443/:1080 -L socks5://:1080

services:
- name: service-0
  addr: :8443
  handler:
    type: forward
  listener:
    type: quic
  forwarder:
    nodes:
    - name: target-0
      addr: :1080
- name: service-1
  addr: :1080
  handler:
    type: socks5
  listener:
    type: tcp

By using port forwarding of the QUIC tunnel, a QUIC data channel is added to the SOCKS5 proxy service on port 1080.

At this time, port 8443 is equivalent to:

gost -L socks5+quic://:8443
