3. Comparison ICON / CCN
Conceptual! Implementation!
• Node model (PIT, FIB, store)! !
• Forwarding engine model! !
• Flow control!
Similar to CCN!
• Sequencing!
• Security!
• Decision engine (strategy layer):! • Microsoft.NET / Mono!
• Different rule management! • Modular architecture!
• Additional functionality (data • Serialization (protobuffer)!
Different from CCN! synchronization)! • Dependency Injection!
• Adapted to opportunistic networks! !
