Comparison of Web traffic performance in W-CDMA mobile satellite systems
Bibliographic record
Abstract
We analyze and compare the performance of Web traffic in two 3G W-CDMA mobile satellite systems, namely GEO and MEO systems assuming random frame error rate (FER). The effect of using two different data rates (i.e. 64 kbps and 144 kbps), two TCP initial window (2*512 and 4*512 bytes) and segment sizes (512 and 1460 bytes) on Web page download time are examined for the two systems. Simulation results presented here show that for 144 kbps data rate the Web traffic requires a FER/spl les/5*10/sup -3/ to avoid any significant increase in Web page download time. The results strongly suggest the use of a data rate /spl ges/144 kbps in order to avoid unacceptable increase in Web page download time in the two mobile satellite systems. The results also show that the MEO system (15000-km altitude) provides only slight reduction in Web page download time in comparison to that in the GEO system. Hence, this slight improvement in Web page download time alone might not merit the selection of MEO over GEO satellites taking into consideration the complexity and the risk associated with the AEO system. Similarly, using larger TCP segment size such as 1460 bytes provides a small but significant reduction in Web page downloads time in comparison to that of 512 bytes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
