Jumbo frames are Ethernet frames with a payload size larger than the standard maximum transmission unit (MTU) of 1500 bytes. This larger payload allows for more data to be transmitted in a single frame, potentially increasing network throughput and reducing CPU overhead on network devices. The typical size of a jumbo frame can range from 9000 bytes up to 9600 bytes, although the exact maximum size can vary depending on the network hardware and configuration.

Implementing jumbo frames requires support from all network devices along the data path, including network interface cards (NICs), switches, and routers. If any device in the path does not support jumbo frames, or if its MTU is not configured to match, the frames will likely be fragmented or dropped, leading to network performance degradation or connectivity issues. Careful configuration and testing are essential when deploying jumbo frames.

The primary benefit of jumbo frames is improved efficiency for high-bandwidth, low-latency applications such as storage area networks (SANs), high-performance computing clusters, and video streaming. By reducing the number of frames needed to transmit a given amount of data, jumbo frames decrease the processing overhead associated with frame encapsulation, decapsulation, and checksum calculations. However, for general-purpose networks with a mix of traffic, the benefits may be less pronounced, and the potential for fragmentation issues can outweigh the advantages.
