Are they compatible in frame format and can they form a composite network without the need to broadcast frames? Could not find anything concrete about this.
- Well, in Wikipedia about 100 gbit it is written: " When developing the PHY-part of the standard, the goals were set: to preserve the format of 802.3 Ethernet frames using the 802.3 MAC format; " - Mike
- Our teacher believes that it is not, and information is not found on this subject - helldrg
- What is meant by Ethernet? pure 802.3? Judging by the general information, the frame format is stored at the MAC level. In principle, you can search for the 802.3b specification for 100GbE - pnp2000
- @ vnn198, still have not answered this question, how can I find the answer, if you want to accomplish your goal here. I hope I am close to him) - helldrg
- @helldrg In terms of specifications, the frame format is compatible with 802.3, i.e. This is all a family of Ethernet, I am not so well versed in networks at a low level, but the only thing that comes to mind from the incompatible is Jumbo Frames - pnp2000

Frame formats for Ethernet are generally compatible across the entire Ethernet family, you can simply switch frames from 100 Gbps to 10 Mbps (you may have to do this in two steps, although the 100G switch may not support another 10 Mbps ). Any channel level functions (L2) are usually compatible with any physical level (L1) determining the environment and speed. Hardware hardware determines whether these technologies are compatible or not. The minimum frame size for Ethernet is 64 bytes, and for 100 Gigabit Ethernet 512 bytes. In general, these two technologies are compatible.
