Hi Experts,

Can anyone explain what jumbo frames means in layman's term?
What does it do, and what does it used for?

Hi d34dp00l13,

Jumbo frames is when the payload of every network package is larger then 1500 bytes.

The wiki article is quite good.

All data transfered on ethernet (network) are binary.
 Data are transfered in packets which are called ethernet frames.

Jumbo frames are ethernet frame bigger than 1500 bytes

Jumbo frame are used to increase network throughput and decrease  CPU overhead

It basically reduce the number for frame to send over network.

It is mostly is used in configuration

1. BACK-to BACK server(where Network card of both server are connected directly)
2. Server to Switch (All network component must support the jumbo frame, that is switch and network card of server)

The jumbo frame configuration are mostly used in datacenter for communication between storage and other servers.

Hello,

In TCP/IP, data is transmitted over the network in "frames". The maximum amount of data in a given frame is referred to as the MTU or maximum transmission unit.

Typically a standard max MTU is 1500 bytes or less. Jumbo frames are anything larger than that, most often 9000 bytes.

Since there are overheads associated with each frame such as CRC checksum, etc. it is possible to transmit large payloads more effectively (less CPU overhead) with jumbo frames, increasing network performance/throughput. Most often they are used for iSCSI SAN storage traffic or NFS shares.

To work correctly, jumbo frames must be supported all the way across the network. For example if using jumbos for iSCSI storage traffic, then SAN, switches and servers must all be configured for jumbo frames. Otherwise any device with a 1500 MTU will drop the traffic along the way.

Nobody mentioned it reduces packet overhead, which is how it actually increases throughput.
