In-flight encryption and compression overview

The in-flight encryption and compression features of Fabric OS allow frames to be encrypted or
compressed at the egress point of an ISL between two Brocade switches, and then to be decrypted
or decompressed at the ingress point of the ISL. These features use port-based encryption and
compression. You can enable the encryption and compression feature for both E_Ports and
EX_Ports on a per-port basis. By default this feature is initially disabled for all ports on a switch.
NOTE
The in-flight encryption and compression features are supported for any port speed, but only on
16G-capable E_Ports and EX_Ports on the Brocade 6510 and 6520 switches and the Brocade DCX
8510 Backbone family.
The purpose of encryption is to provide security for frames while they are in flight between two
switches. The purpose of compression is for better bandwidth use on the ISLs, especially over long
distance. An average compression ratio of 2:1 is provided. Frames are never left in an encrypted or
compressed state when delivered to an end device. Both ends of the ISL must terminate in
16G-capable FC ports.
Encryption and compression can be enabled at the same time for an ISL, or you can enable either
encryption or compression selectively.
three Brocade switches. One link is configured with encryption and compression, one with just
encryption, and one with just compression.
