If I understand correctly, the cellular companies do some hairy, hairy manipulations of TCP in order to preserve data connections across cell towers.
Do we need a better protocol for cell data and would this improve throughput and latency?
- topranks 8y agoNot true. Your TCP traffic is encapsulated in a GTP tunnel from the head end to the local tower / aggregation point. The network looks after moving / switching the endpoint of the tunnel as you move from cell to cell. Basically all the hard stuff is done to make the tunnel endpoint roam from cell to cell. Your TCP stream, inside the tunnel, doesn't realise anything is happening and doesn't need to change in any way to keep working.
