JSOR features and design (Linux only)
JSOR provides support for plain and NIO stream socket applications, IPv6, and an optional method for allowing RDMA-enabled servers to accept TCP clients. By intercepting socket stream calls, JSOR manages all control operations and data routing for a Java™ application.
- RMDA-enabled Java plain and NIO stream sockets
- Support for IPv6
- TCP/IP fall back support for RDMA server sockets
- Extensive call tracing at the JSOR native level
You enable JSOR by specifying a system property when you start your application, which specifies the server or client configuration file. For more information about enabling JSOR, see Enabling Java Sockets over Remote Direct Memory Access (JSOR) (Linux only).
- Fast data path
- The JSOR library uses the OpenFabrics Software (OFS) userspace verbs module to communicate directly with the RDMA network interface adapter. This route is typically used for sending data. For more information about using userspace verbs, see Userspace verbs access.
- Slow control path
- The JSOR library interacts with a device-dependent kernel verbs module for controlling and managing the RDMA resource objects. This path is used mainly for establishing connections.
