Module protocol 

Defines the networking protocol used at each stage in a connection. Consists of a series of messages that are sent across the network at the different connection stages.

When a node connects to a network for the first time, it must follow a seed protocol, which provides it with a list of network hosts to connect to. To establish a connection to another node, nodes must send version and version acknowledgement messages. During a connection, nodes continually get address and get-address messages to inform each other about what nodes are on the network. Nodes also send out a ping and pong message which keeps the network from shutting down.

Protocol submodule also implements a jobs manager that handles the asynchronous execution of the protocols.

Modules

protocol_address

Protocol for address and get-address messages.

protocol_base

Base trait for implementing P2P protocols

protocol_generic

Generic protocol to receive specified structure messages.

protocol_jobs_manager

Manages the tasks for the network protocol.

protocol_ping

Protocol for ping-pong keepalive messages.

protocol_registry

Interface for registering arbitrary P2P protocols

protocol_seed

Seed server protocol. Seed server is used when connecting to the network for the first time. Returns a list of peers that nodes can connect to.

protocol_version

Protocol for version information handshake between nodes at the start of a connection. This is the first step when establishing a p2p conn.

Functions

register_default_protocols

Register the default network protocols for a p2p instance.
