Data Distribution Service in Linux Kernel Module

The Publish/Subscribe (Pub/Sub) paradigm has become a key component of the Navy Open Systems Architecture (OA) initiative. The finalization of the Data Distribution Service (DDS) specification by the Object Management Group has solidified a common approach for performing data centric distributed computing for real-time applications. However, there are potential latencies induced in the data exchanges that occur through DDS compliant product as a result of the context switching that occurs as the computing device switching between user and kernel space. This SBIR is focused on determining the feasibility of implementing the DDS specification as a Linux Kernel Module (LKM). If a successful, DDS LKM can be created, the resultant performance of this implementation vice a DDS that is solely resident in the user space will also be measured. Additionally, Lakota is proposing the incorporation of functionality within this Kernel module that will support Adaptive Resource Management to ensure that the requested Quality of Service agreements are maintained.
