- A New TCP for Persistent Packet Reordering
- Most standard implementations of TCP perform poorly when packets are reordered. This paper proposes a new version of TCP that maintains high throughput when reordering occurs and yet, when packet reordering does not occur, is friendly to other versions of TCP. The proposed TCP variant, or TCP-PR, does not rely...
