| Pair | Difference |
|---|---|
| IP address vs port | Interface/network delivery vs process endpoint |
| TCP vs UDP | Ordered byte stream with recovery vs datagrams without built-in delivery recovery |
| rwnd vs cwnd | Receiver capacity vs network congestion allowance |
| Flow control vs congestion control | Receiver protection vs shared network protection |
| Open loop vs closed loop | Prevention without runtime congestion feedback vs measurement/feedback/reaction |
| Delay vs jitter | Time taken vs variation in time taken |
| Leaky queue vs token bucket | Stores data to smooth output vs stores permission to allow bounded bursts |
| Shaper vs policer | Delays nonconforming traffic vs measures and applies mark/drop policy |
| SCTP streams vs multihoming | Separate message-ordering streams vs alternate endpoint addresses/paths |
For the observed TCP question, draw establishment, data transfer and termination, and explain the arrows. Separate sequence-number calculation drills are optional; they were not asked in the supplied papers.
