Nework Management

• Functional model (User-oriented)
• Configuration Management
• Fault Management
• Performance Management
• Security Management
• Accounting Management

10
System Definition

• Logger

11
System Definition

• Fault Management
• Logs all alarms and events
• Simple Network Management Protocol (SNMP)
• Primary Goal
• Monitoring of the main components of the Wave
  Dragon Control System
• Monitoring of alive status
• Status information is to be presented graphically
• System Administrators and Clients
• Secondary Goal
• Process the sample file from the DAQ system

12
Object Oriented Analysis and Design

• Advantages
• Structure
• Reduces complexity
• Complete method (Covers Analysis and Design)
• Repeted development
• Suited for software development

13
Object Oriented Analysis and Design

• Analysis
• Problem domain
• Part of the real world that is managed by the
  system.
• Application domain
• Organization that manages, monitors and controls
  the problem domain

14
Object Oriented Analysis and Design

• Design
• Component
• Processes
• Model Component
• Function Component
• Interface Component

• Results
• Discussion

17
Wave Dragon Management System

• Presentation of the system

18
Wave Dragon Management System

• Presentation of the system
• Two Tier management model
• Fault Management
• Remote monitoring
• SNMP management proxy server
• Distributed approach
• Versatile system
• Logger focus
• Standard PC configuration (Linux box)
• Scalability

19
Wave Dragon Management System

• Event driven system
• SNMPv2
• Transport Mapping (TCP)
• SNMPv3 migration (security)

20
Management System Design

• Method Object Oriented Design (OOD)
• Components
• Logger Manager
• Processes
• Concurrency synchronicity
• Active Objects assigned a process
• Multi programming (threads)
• FIFO queue solve concurrency problems
• Model
• Management Information Base (MIB)

21
Management System Design

• Functions
• Logger

22
Management System Design

• Functions
• Manager

23
Management System Design

• Interfaces
• PLC
• UPS
• PC

24
Results

• Prototype
• Logger implemented
• Except PLC pinger
• Manager partly implemented
• Capable of receiving Trap information
• Primary goal fulfilled according to the system
  definition
• SNMP based Wave Dragon management system
  developed and prototype tested
• It Works!

25
Discussion

• Enhanced Management features
• Configuration Management
• Change control programs/algorithms
• Get current software/hardware configuration
• Security Management
• Control access level
• Logging of administrator logins and changes
• Security
• Administrator login through VPN (configuration)
• Migration to SNMPv3

26
Discussion

• The Wave Dragon Management System facilitate
  enhanced performance
• Remote monitoring
• Performance monitoring
• Capable of monitoring multiple Wave Dragons
• Integrated scalability
• Warning system
• Public access to power production statistics
• Enhanced focus on wave energy as an electricity
  source
