Real-Time Innovations (RTI) has updated its Connext software framework to support the development and deployment of remotely-operated autonomous systems. 

Autonomous systems typically operate in inaccessible, remote, or hazardous environments. Examples include underwater drones, remotely-accessible medical devices, space systems, and construction and mining robots. Since artificial intelligence cannot handle all situations, these applications must use remote operators to supervise and intervene in difficult scenarios.

Connext has been used widely in many driverless car development platforms, which has demonstrated the need for high reliability and real-time performance even though connectivity in these inhospitable environments is often unreliable and low bandwidth. Thi scan be over local, wide area, public and private networks.

 Connext 6.1 introduces features to enable easy real-time remote operation over any network. For instance, if the network connection changes as the system moves, connectivity is seamless without reconnecting, secure without renegotiating, and reliable without losing information. Thus, remote operations can continue in real time without interruption.

Connext 6.1 supports and optimizes fast communications across highly variable local (LAN) and wide-area networks (WAN) and does not require software changes to support diverse network types. Its Application Programming Interfaces (API) abstracts the underlying networks, allowing developers to target any environment.

New capabilities in Connext 6.1 include real-time WAN transport that provides reliable, low latency and secure communication over lossy, low bandwidth, and public networks. It supports Network Address Translation (NAT) traversal and mobile applications with changing Internet addresses.

A Cloud Discovery Service simplifies deployment of dynamic systems in which applications, assets, and their network addresses may not be known at configuration time. It provides a means for applications to discover each other and directly communicate, peer-to-peer. This minimizes latency and maximizes throughput. It is far superior to traditional centralized broker solutions.

Built-in data compression improves efficiency over bandwidth-constrained networks. Compression maximizes bandwidth use, lowering overhead and latency while increasing throughput. A choice of compression algorithms and levels allows optimization of processor versus network utilization for different payload types.

Support for .NET Core 5 lets developers use C# and run their applications on any platform that supports .NET Standard 2.0. In addition to Windows, this includes Linux, macOS and the Unity game engine using in simulation systems.

A new System Designer tool provides a graphical way to easily and intuitively specify the configuration and interfaces in a Connext-based system. This helps ensure that applications adhere to a common architecture and can interoperate in a plug-and-play manner. 

Administration Console includes enhanced graphical views to make it easier to visualize the components of live large-scale systems and their interconnectivity. This allows OEMs and systems integrators to better observe behavior during test and deployment, and to more quickly identify configuration or network problems.
