What type of packet would have frame size 64Byte?

[osw200051]

Dear Expert,

When i carry the throughput test, there are usually have different frame size, such as 64Byte, 128Byte, 256 Bytes .....1518Byte.

My questions are:

1. Only this size can happen on the data network? can I have the packet size such as 90 Bytes?

2. What type of service that would have frame size 64Byte? such as keepalive packet? voice packet?

Thanks.

Hello,

anything 64 bytes and above is possible. 64 bytes is the minimum Ethernet frame size. If you see packets that small (64 bytes) it could be ARP traffic. Do you have a packet analyzer such as Wireshark available ?

Hi Georg Pauwen,

That means ARP frame would small then 64 Bytes?

But why the Netscout tester only can test 64, 128, 256, 512,1024, 1280, 1518 frame size but not other?

Or on the data network world, there are only exist the above frame size ?

Cannot fully comment on Netscout, but it might be grouping variable sized frames into "buckets" of sizes. Ethernet frames can vary in size, by byte, from the minimum to the maximum size.

Thanks Joseph,

Got your point.
