| Abstract | The reliability of the K11-Band satellite network operation suffers during the rainy season where packet errors occur more frequently. At the transmission level, to make the network operational through the rain, one could adjust the coding rate to of Forward Error Correction (FEC), however, this is not practical in practice. In this study, it is proposed that to make the network operational uninterrupted during such a condition, a reduced traffic rate should be controlled by the network interface layer. Instead of relying on the flow control at the protocol level, we propose to change the physical packet sizes by modifying the maximum transmission units (MTUs). From experiments on TCP/IP networks, it is observable that the MTU is linearly related to the Round-Trip-Time (Rrr). Thus, under the rainy condition, where the RTT tends to increase as well as the average bit rate generated by users, we propose to reduce the MTU in order to reduce the load on the transmission network. |
