LINX (IPC)

LINX is a new generation of the OSE Link Handler for Inter-process communications (IPC) that provides higher performance and more robust functionality developed by ENEA AB in Sweden. LINX was released as free and open-source software, subject to the requirements of the GNU General Public License (GPL), version 2.

Utilizing direct message passing, LINX scales from DSPs and microcontrollers to 64-bit CPUs. LINX is independent of the underlying processor, operating system, or interconnect, supports control and data plane applications over reliable and unreliable media.

LINX also supports any distributed system topology, from a single processor on a single blade, to large networks with complex cluster topologies deployed on hundreds of processors in a multi-rack system.

LINX enable application processes distributed across multiple operating systems, CPUs, and interconnects to communicate, as if they were running on the same CPU under the same operating system. LINX provides the same services to the application regardless of hardware, operating system, physical interconnect, and network topology.

LINX utilizes an innovative address map for connections that greatly enhances flexibility and scalability. Unlike other IPC models, which must maintain the entire system address map on every node in the system, LINX nodes store only the addresses needed for active connections.
