### Good Performance
Utilization: channel should be efficient

Fairness: channel should be evenly divided.

```
x = throughput of node
N = number of nodes
```

**Goal: Ensure high utilization and high fairness**

:::success
1. Utilization: channel is efficient
2. Fairness: channel is divided evenly
3. Bounded wait: upper bound on wait before successful transmission
4. Dynamism: handle variability
5. Scalability: work for a large number of users
