Network service configuration.
Fields§
§net_config_path: Option<PathBuf>
Directory path to store network-specific configuration. None means nothing will be saved.
listen_addresses: Vec<Multiaddr, Global>
Multiaddresses to listen for incoming connections.
public_addresses: Vec<Multiaddr, Global>
Multiaddresses to advertise. Detected automatically if empty.
boot_nodes: Vec<MultiaddrWithPeerId, Global>
List of initial node addresses
node_key: NodeKeyConfig
The node key configuration, which determines the node’s network identity keypair.
request_response_protocols: Vec<ProtocolConfig, Global>
List of request-response protocols that the node supports.
default_peers_set: SetConfig
Configuration for the default set of nodes used for block syncing and transactions.
default_peers_set_num_full: u32
Number of substreams to reserve for full nodes for block syncing and transactions. Any other slot will be dedicated to light nodes.
This value is implicitly capped to default_set.out_peers + default_set.in_peers
.
extra_sets: Vec<NonDefaultSetConfig, Global>
Configuration for extra sets of nodes.
client_version: String
Client identifier. Sent over the wire for debugging purposes.
node_name: String
Name of the node. Sent over the wire for debugging purposes.
transport: TransportConfig
Configuration for the transport layer.
max_parallel_downloads: u32
Maximum number of peers to ask the same blocks in parallel.
sync_mode: SyncMode
Initial syncing mode.
enable_dht_random_walk: bool
True if Kademlia random discovery should be enabled.
If true, the node will automatically randomly walk the DHT in order to find new peers.
allow_non_globals_in_dht: bool
Should we insert non-global addresses into the DHT?
kademlia_disjoint_query_paths: bool
Require iterative Kademlia DHT queries to use disjoint paths for increased resiliency in the presence of potentially adversarial nodes.
ipfs_server: bool
Enable serving block data over IPFS bitswap.
yamux_window_size: Option<u32>
Size of Yamux receive window of all substreams. None
for the default (256kiB).
Any value less than 256kiB is invalid.
Context
By design, notifications substreams on top of Yamux connections only allow up to N
bytes
to be transferred at a time, where N
is the Yamux receive window size configurable here.
This means, in practice, that every N
bytes must be acknowledged by the receiver before
the sender can send more data. The maximum bandwidth of each notifications substream is
therefore N / round_trip_time
.
It is recommended to leave this to None
, and use a request-response protocol instead if
a large amount of data must be transferred. The reason why the value is configurable is
that some Substrate users mis-use notification protocols to send large amounts of data.
As such, this option isn’t designed to stay and will likely get removed in the future.
Note that configuring a value here isn’t a modification of the Yamux protocol, but rather a modification of the way the implementation works. Different nodes with different configured values remain compatible with each other.
