Module internet2::transport

LNP transport level works with framed messages of defined size. This messages can be put into different underlying transport protocols, including streaming protocols (like TCP), or overlaid over application-level protocols like HTTP, Websockets, SMTP (for high-latency communication networks). Current mod implements such overlays and provides TCP with the required framing functionality (this variant is called FTCP). It also integrates with ZMQ such that the upper level can abstract for a particular transport protocol used.

Modules

ftcp	Framed TCP protocol: reads & writes frames (corresponding to LNP messages) from TCP stream
socket_addr	Module supports transport-level addressing, i.e. the one used before encryption/decryption of the actual data are taking place. These addresses is mostly used internally and does not include information about node public key (for that purpose you need to use session-level address structures like NodeLocator and NodeAddress).

Constants

FRAME_PREFIX_SIZE	Size of the frame prefix which is not included into payload size, consisting of the 2-bytes message size data and 16-byte MAC of the payload length
FRAME_SUFFIX_SIZE	Size of the frame suffix represented by a 16-byte MAC of the frame payload
MAX_FRAME_PAYLOAD_SIZE	Maximum size of the frame payload which may be expressed by two bytes
MAX_FRAME_SIZE	Maximum size of the transport frame; chosen in compliance with LN specs

Traits

Duplex	Marker trait for types that can provide a concrete implementation for both frame parser implementing RecvFrame and frame composer implementing SendFrame. These types must also implement [Bipolar], i.e. they must be splittable into the receiving and sending half-types.
RecvFrame	Frame receiving type which is able to parse raw data (streamed or framed by an underlying overlaid protocol such as ZMQ, HTTP, Websocket).
SendFrame	Frame sending type which is able to compose frame with a given raw data and send it via an underlying overlaid protocol such as ZMQ, HTTP, Websocket.
