TCP transport configuration.

Fields

listen_addresses: Vec<Multiaddr>

Listen address for the transport.

Default listen addresses are [“/ip4/0.0.0.0/tcp/0”, “/ip6/::/tcp/0”].

reuse_port: bool

Whether to set SO_REUSEPORT and bind a socket to the listen address port for outbound connections.

Note that SO_REUSEADDR is always set on listening sockets.

Defaults to true.

nodelay: bool

Enable TCP_NODELAY.

Defaults to false.

yamux_config: Config

Yamux configuration.

noise_read_ahead_frame_count: usize

Noise read-ahead frame count.

Specifies how many Noise frames are read per call to the underlying socket.

By default this is configured to 5 so each call to the underlying socket can read up to 5 Noise frame per call. Fewer frames may be read if there isn’t enough data in the socket. Each Noise frame is 65 KB so the default setting allocates 65 KB * 5 = 325 KB per connection.

noise_write_buffer_size: usize

Noise write buffer size.

Specifes how many Noise frames are tried to be coalesced into a single system call. By default the value is set to 2 which means that the NoiseSocket will allocate 130 KB for each outgoing connection.

The write buffer size is separate from the read-ahead frame count so by default the Noise code will allocate 2 * 65 KB + 5 * 65 KB = 455 KB per connection.

connection_open_timeout: Duration

Connection open timeout.

How long should litep2p wait for a connection to be opened before the host is deemed unreachable.

substream_open_timeout: Duration

Substream open timeout.

How long should litep2p wait for a substream to be opened before considering the substream rejected.
