| Summary: | This paper presents the findings on TCP
performance measurements in the LA process during
the deployment of GPRS CS1 and CS2 coding schemes
and after the activation of two more coding schemes,
CS3 and CS4. The measurements are done under
various network scenarios based on users’ physical
locations in one of Malaysia’s commercially deployed
live GPRS networks. End-to-end evaluation of FTP
application is used for the assessment together with
tracing at the GPRS air interface. The results show
that TCP works well in the LA process and can cope
with the frequent switching between the coding
schemes without any problem. Throughput
performance is observed to be stable in all scenarios.
The activation of higher coding schemes aided by TCP
tuning also proves to be beneficial by the 23% increase
in average throughput seen for urban areas. |
