Configuration

Setup

You can configure the requiem settings in the config file (config/config.exs, config/releases.exs, etc.) by writing the following

config :my_app, MyQuicHandler,
  port: 443,
  cert_chain: "cert/cert.pem",
  priv_key: "cert/priv.pem",
  max_idle_timeout: 300000

Key	Default	Description
host	0.0.0.0	The host value to use when opening the UDP port
port	443	The port number to use for UDP
socket_pool_size	0	Number of sockets you want to create for UDP packet. if set 0, number of CPU is set automatically.
socket_read_timeout	100	millisecond. for UDP socket's "recv"
socket_send_timeout	100	millisecond. for UDP socket's "send"
dispatcher_pool_size	10	The number of dispatchers that will check the QUIC header after the socket receives a packet and process it appropriately in parallel. And this number is for each socket. If set 10 for this, and set 8 for socket_pool_size, 80 dispatchers will be created.
token_secret	random 16 bytes	Secret value to be used for encryption when generating retry-token
connection_id_secret	random 32 bytes	This is the secret value used to generate a new SCID for the server based on the DCID value embedded in the header by the client
allow_address_routing	false	Whether to enable routing to the Connection using the source address when the DCID embedding in the header is omitted
