AI Technical Summary
Industrial automation systems face challenges in efficiently processing a large number of short messages due to limited filtering capabilities of network adapters at higher protocol layers, leading to unnecessary strain on subscriber systems, particularly when using common and cost-effective network adapters.
Implementing a method where first automation devices send payload data to multicast groups, with second automation devices registering as participants and using network adapters with Express Data Path Sockets (XDP Sockets) to forward datagrams to a filter unit, allowing control applications to specify forwarding criteria directly, thereby bypassing the operating system processing.
Enables efficient processing of user data using widely available and cost-effective network cards by implementing subscriber-side filter units near the network adapter, reducing load on network stacks and ensuring deterministic communication behavior.
