Table 2 Open implementation issues for federated FiWi-MANET deployments
From: Multi-domain SDN controller federation in hybrid FiWi-MANET networks
Scenario | Covered by OpenFlow | Features | What is needed to be addressed | Evolving | Impact |
|---|---|---|---|---|---|
Load balancing | Yes | High-throughput | Flow tables installed in devices | Fast | MANET: high FiWi: high |
Fair bandwidth allocation | No | Fairness | Hardware extensions to support SDN deployment in MANET devices and OpenFlow extensions to provide fairness monitoring | Not so fast | MANET: high FiWi: medium |
Traffic engineering | No | Low latency, low jitter | OpenFlow extensions to support more complicated decisions (e.g., LTE framing characteristics adjustment) | Slowly | MANET: high FiWi: medium |
Energy management | No | Energy savings | Hardware abstractions to support power management | Very slowly | MANET: high FiWi: medium |
