UDTP

UDTP (Up/Down Transport Protocol) is a transport layer protocol that contains mechanisms for ensuring transmission quality with guaranteed delivery in packet-based networks with an explicitly organized connection.
UDTP provides the following types of services for apps:
* bandwidth allocation with transmission latency control;
* ordered delivery of user data;
* guaranteed data delivery;
* asymmetrical (up/down) data transmission;
* multiplexing / de-multiplexing of user data;
* support of forward error correction in data transmission;
* data encryption support during transmission;
* data transfer support in the form of a file, stream or message;
* resilience to failures and changes on the network level;
* mobile users support;
* support for multicast and broadcast connections on both sides;
* no duplicates during data delivery;
* real-time and time-insensitive data transfer support in a single communication channel.
UDTP is an integrated part of IPv17 network model, which differs from the reference model of open systems interconnection (ITU X. 200).
