WAP1.x would
take an advantage if content size were small,

HTTP/TCP would
take an advantage if content size were large.

500byte(64kbps):
WTP1.x is better than HTTP/TCP.

Reason
|
|
|
|
1. |
Because TCP slow
start algorithm prevents making full use of network
|
|
|
resources in the
slow start phase, WTP is better than TCP in case of
|
|
|
small contents.
|
|
|
|
2. |
WTP responder
can send the number of packets based on the window
|
|
|
size, but the WTP
responder has to wait until the subsequent
|
|
|
acknowledgement
is received. That waiting time results in the increase
|
|
|
of total response
time.
|
|
|
|
3. |
TCP performance
is better when transmitting large contents because
|
|
|
dynamic flow
control mechanism works well provided that the large size
|
|
|
of buffer is
prepared in the client.
