IP fragmentation can cause excessive retransmissions when fragments encounter packet loss and reliable protocols such as TCP must retransmit all of the fragments in order to recover from the loss of a single fragment.
For more information on IP Fragmentation, please visit the below link:
https://en.wikipedia.org/wiki/IP_fragmentationJumbo frames are packets that are larger than the standard Ethernet frame size of 1,500 bytes. These larger frames can improve network performance by reducing overhead and increasing throughput, but they can also introduce issues such as packet fragmentation and compatibility problems.
If you are experiencing packet loss when accessing AWS resources, there are several potential causes. One possible issue is that the jumbo frames being used on your network are not compatible with the AWS network infrastructure. In this case, you may need to adjust your network configuration to resolve the issue.
Of the options provided, the most likely solution is to consider lowering the Maximum Transmission Unit (MTU) for your network. The MTU is the largest size of packet that can be transmitted over a network, and it is typically set to the default value of 1,500 bytes. If you are using jumbo frames, you may need to lower the MTU to ensure that packets are not being fragmented when sent to AWS resources. Fragmentation can lead to packet loss and other performance issues.
Removing the "Do not Fragment" flag on packets is unlikely to solve the problem, as this flag is typically used to prevent packet fragmentation. If you remove the flag, you may increase the likelihood of packet fragmentation and further exacerbate the packet loss issue.
Using Direct Connect can also improve network performance by providing a dedicated, private connection between your network and AWS resources. However, this solution is not necessarily related to the jumbo frames issue and may not solve the problem on its own.
Calling AWS support may be necessary if you are unable to resolve the issue through other means, but it is not a specific solution to the problem of packet loss when using jumbo frames.
In summary, if you are experiencing packet loss when accessing AWS resources and using jumbo frames on your network, the most likely solution is to consider lowering the MTU for your network to prevent packet fragmentation.
