idea:
modify network layer software at base station
|
|
|
| n |
changes
are transparent to MH and FH
|
|
|
|
– |
no
changes in TCP semantics (unlike I-TCP)
|
|
|
|
– |
less
software overhead (packets pass TCP layer only twice)
|
|
|
|
– |
no
application relinking on mobile host
|
|
|
| n |
modifications
are mostly in caching packets and
|
|
|
|
performing
local retransmissions across the wireless link
|
|
|
by
monitoring (snooping) on TCP acks
|
|
|
| n |
results
are impressive:
|
|
|
|
– |
speedups
of up to 20 times over regular TCP
|
|
|
|
– |
more
robustness when dealing with multiple packet losses
