RIST Reliable Internet Stream Transport

Tabs

Overview

The Reliable Internet Stream Transport (RIST) protocol allows the use of the Internet as a cost-effective, reliable, low-latency contribution link. Developed jointly by an aggregate group of experts and built on top of existing RFC standards, RIST benefits from cumulative years of real-world experience. RIST leads to a more technically robust solution than any single vendor can ever create – no matter the application, use case, or environment it is deployed in.

Features

Developed jointly by an aggregate group of experts and built on top of existing RFC standards
Allows direct, low-cost usage over interconnected data networks with the reliability of expensive, high-commitment dedicated connections
Easily available as a software option in numerous Cobalt encoder and decoder products
Supported RIST Simple Profile features include:
• Reliable delivery over the Internet, using ARQ to recover from packet loss.
• Tunable end-to-end latency to adapt to a variety of link conditions.
• Retransmission throttling for link stability.
• Support for multi-link operation including:
- Bonding (traffic can be divided into multiple links, whose capacity is combined).
- Seamless Switching (traffic can be replicated over multiple links and merged at the receiver – if one
of the links goes down there is no effect on the signal).
Supported RIST Main Profile features include:
• Tunneling:
- Combine one or more streams into a single UDP session.
- Open only one UDP port, which can be done either at the sender or the receiver side.
• Encryption: protect your valuable content over the Internet. Both AES-128 and AES-256 modes are
supported. (*)
• Authentication: both sides of a connection can authenticate each other, ensuring that only authorized
endpoints can communicate. Both RSA and ECDSA authentication modes are supported. (*)
(*) Encryption and authentication not available for the 9223 and BBG-1123 encoder series.
