Transport Layer
Participation in power-efficient communication schemes
- Need to carefully consider the trade-offs between coding at the link layer and retransmission at the transport layer to optimize use of overall communication resources - may dictate mixed-loss operation at transport
Adaptation to changing network conditions
- May require QOS-responsive reliable transport
- Efficient accommodation of link outages
- Explicit congestion signaling and prompt response
- Robust error trend indication with appropriate response
Data rate asymmetry in in-situ satellite communications
- Must be able to accommodate >100:1 asymmetries
- Without degrading use of the high-rate side
- While still performing useful functions on the :1 side
