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

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

8. 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

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

10. 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

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

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

14. 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)

15. 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

16. 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
