Abstract: The traditional TCP/IP stack requires verification and regeneration of the CRC code in every router to detect transmission errors. For IPv6 packet transmission over high speed networks, this task is redundant because of the very rare transmission error and thus introduces unnecessary latency. The CRC Extension Header (CEH) was proposed to eliminate the unnecessary duplication of error detection. Since IPv6 packets are transmitted over Ethernet, the packet size ranges from 1280 up to 1500 bytes. In the near future, the size will increase with the advance of underlying technology such as 100 Gigabit Ethernet. This paper studies the effect of various IPv6 packet sizes with the implementation of CEH on the processing time and network latency. Experiments were done by transmitting various IPv6 packet sizes over high speed networks. The results showed that higher packet sizes increases processing time and network latency.

Keywords: Routing, TCP/IP, IPv6, error correction.
