# Session 16: Gateways
|
||
|
||
## Summary
|
||
|
||
Gateway connections — inter-cluster message routing. Gateways enable NATS super-clusters where messages flow between independent clusters.
|
||
|
||
## Scope
|
||
|
||
| Go File | Features | Feature IDs | Go LOC |
|
||
|---------|----------|-------------|--------|
|
||
| server/gateway.go | 91 | 1263–1353 | 2,816 |
|
||
| **Total** | **91** | | **2,816** |
|
||
|
||
## .NET Classes
|
||
|
||
- `GatewayHandler` — gateway connection management
|
||
- `GatewayCfg` — gateway configuration
|
||
- `ServerGateway` — per-server gateway state
|
||
- `GatewayInterestMode` — interest/optimistic mode tracking
|
||
- `GwReplyMapping` — reply-to subject mapping for gateways
|
||
- `ClientConnection` (partial — gateway-specific methods)
|
||
|
||
## Test Files
|
||
|
||
| Test File | Tests | Test IDs |
|
||
|-----------|-------|----------|
|
||
| server/gateway_test.go | 88 | 600–687 |
|
||
| **Total** | **88** | |
|
||
|
||
## Dependencies
|
||
|
||
- Session 01 (Foundation Types)
|
||
- Session 07 (Protocol Parser)
|
||
- Session 08 (Client Connection)
|
||
- Session 09 (Server Core Part 1)
|
||
- Session 11 (Accounts — for interest propagation)
|
||
- Session 14 (Routes)
|
||
|
||
## .NET Target Location
|
||
|
||
- `dotnet/src/ZB.MOM.NatsNet.Server/Gateway/`
|
||
|
||
## Notes
|
||
|
||
- Gateway protocol has optimistic and interest-only modes
|
||
- Account-aware interest propagation is complex
|
||
- 88 tests — thorough coverage of gateway scenarios
