Realization of reliable high speed data transfer over UDP with continuous storage

摘要

When speaking about high speed transfer, generally one thinks of 1–10 Gbps throughput. At the same time in case of a low performance device, 10–20 Mibps is also considered as high speed. The present case discusses the MOD5270 Ethernet module by Netburner Inc. for the 147,5 MHz processor of which it was a challenge to achieve this speed. The plan was to achieve 48 Mibps, however, according to the manufacturer this device is capable of reaching only about half of this speed. This fact was proven over TCP, so only the UDP was able to fulfill the given requirements. In that case the task was to recover the lost packets, therefore our own protocol was developed.
