Outline Technology Overview Stack Overview Project’s goal The Protocol Analyzer Future Work

Stack Overview Based on OSI 7-Layers Network Reference model with some modification to match the specific requirements of command and control applications

Stack Overview The Yitran protocol stack consists of : Physical layer consisting of the physical interface to the power line media Media access control layer providing Y-Net stack interface for lower layer communication services Network Layer providing Y-Net stack interface for advanced networking services such as admission, routing and addressing Higher layers are implemented by third part companies for various applications

Outline Technology Overview Stack Overview Project’s goal The Protocol Analyzer Future Work

Project’s Goal Verify the implementation of the Stack in the embedded environment Analyze the protocol algorithms from different aspects: Correctness Performance Calibration Improvement The higher layers of the stack were not tested nor implemented and the results and tools of this project will significantly assist in future development and tests

Outline Technology Overview Stack Overview Project’s goal The Protocol Analyzer Future Work

The Protocol Analyzer Host Application that interfaces with a packet sniffer in order to parse, display and analyze incoming traffic

The Protocol Analyzer Functions and Services: Packet Parsing Packet Display User Control Analysis Abilities

The Protocol Analyzer Packet Parsing Identifies different protocol versions and acts accordingly using configuration files – Each protocol will have an XML configuration file Layer parse is dynamic (the packets may not have upper layers)

The Protocol Analyzer Packet Display & User Control The display shows for each packet: Rx time Serial number Fields, subfields and contents Display filter according to different parameters as: Addresses Packet types Data Types

The Protocol Analyzer Analysis Abilities The following statistical data is saved to text files: Network Congestion Network Topologies Network Statistics Error Statistics Station Statistics Station ID Network ID Num Of FP Num Of PE Num Of Disconnections 1 322 12336 3267 21 2245 5644 22 6788 346 2 31 454 5649 564

Outline Technology Overview Stack Overview Project’s goal The Protocol Analyzer Future Work

Future Work Finalize implementation of the protocol analyzer Algorithmic tests using different topologies and scenarios High load tests Data Analysis Comparison of results with simulation results Suggestion of further improvements according to the analysis of the algorithms
