|
|
|
|
This document breaks down the Phase 3 implementation plan into specific tasks to be completed. Each task represents a discrete unit of work that can be implemented and tested independently.
|
|
|
|

|
|
- [ ] Create `RoutingTable` interface for route storage and retrieval
|
|
- [ ] Define `IMessageRouter` interface with core routing methods
|
|
- [ ] Create `RoutingStrategy` enum for different routing approaches
|
|
- [ ] Define `RoutingConfig` interface for router configuration
|
|
|
|
## 2. Basic Routing Table Implementation
|
|
|
|
- [ ] Implement `BasicRoutingTable` class

|
- [ ] Add utility methods for finding optimal routes
|
|
- [ ] Create comprehensive unit tests for routing table
|
|
|
|
## 3. Message Priority and Batching
|

- [ ] Create `FloodMessageRouter` for broadcast-style delivery
|
|
- [ ] Implement `ShortestPathRouter` for optimized routing
|
|
- [ ] Add `RandomRouter` for testing and simulation
|
|
- [ ] Create strategy factory for dynamic strategy creation
|
|
- [ ] Test each strategy independently and in combination
|
|
|
|
