  1. XLayer: A Cross-Layer Communications Substrate for Tactical Environments Marco Carvalho, Ph.D.Research ScientistInstitute for Human and Machine CognitionUniversity of West Florida

  2. Outline • Motivation • Technical Approach and Design • Services and Applications • Related Projects and Transitions • Upcoming Experiments and Demonstrations

  3. Motivation

  4. Project Objectives Goal: To Investigate, design and Implement a modular and cross-layer communications substrate for Tactical Environments. Proposed Capabilities: • Seamless IP-like communications between nodes that may be connected through heterogeneous protocols and data links. • Efficient and predictable mechanisms for detection, addressing and discovery of platforms and services. • Monitoring of network and link capacity and reliability, enabling advanced QoS support and the online adaptation of applications. • Enhanced routing, transport and dissemination mechanisms that are tolerant to node failures, network disruptions, and link delays. • Provide an extensible two-way interface between applications and underlying communications infrastructure

  5. Proposed Approach

  6. Interface Integration Models • Goal: A modular (and easily configurable) architecture that supports different modes of integration between the platform, the communications infrastructure and applications.

  7. The XLayer Architecture

  8. Core Services • Message Propagation Service • Node Monitoring • Resource Information Sharing • Adaptive Service Discovery • Adaptive Platform Discovery • Network Management • Group Management • NetTAP (virtual sniffing) • Transport Service • Multi-path and adaptive transport. • Dissemination Service

  9. Interfacing with the Network XLayer Adaptors: Adaptors are internal cross-layer objects that represent external devices such as network interfaces, GPS) within the cross-layer. Apps (Adaptor) Host XLayer Controller App1 App2 Cross-Layer Service Adaptor Adaptor Radio X

  10. Interfacing with ApplicationsThe XLayer Proxy • The XLayer Proxy is a client API that allowsapplications to use a XLayer Service. • Available in C++ and Java. • The XLayer Proxy can make use of both local and remote XLayer Service instances. (Proxy) Host App1 App2 Cross-Layer Service Radio X
