Deployment Issues (4/4)
Dealing with heterogeneity:
- The proposed scheme can be operated in a network which doesn’t provide service differentiation.
- It requires constant monitoring to detect service differentiation on a connection path.
- In a network which supports service discrimination, the number of priority packets transmitted between successive drops is greater than the number of best-effort packets.
- When this is not the case, the source turns off the marking and the windowing algorithm, reverting to normal TCP.
