TCP considerations
Timer initial value can lead to spurious retransmissions
- Need to make the timer configurable or user needs to be aware of the problems
Congestion management: handoff interpreted as loss by Van Jacobson’s algorithm
- Use of SACK option helps: prevents unnecessary retransmissions
- Transparency => mechanisms outside the network layer. Eg snoop protocol
Transmission and timeout freezing on wireless links
TCP spoofing or connection segmentation
