What is Flex Ethernet?

FlexE is a key technology used in various industries for high density requirements to deliver faster network speeds vs emerging Ethernet solutions. It provides a generic mechanism for supporting a variety of Ethernet MAC rates that may or may not correspond to any existing Ethernet PHY rate. This includes MAC rates that are both greater than (through bonding) and less than (through sub-rate and channelization) Ethernet PHY rates used to carry FlexE.

FlexE dissociates Ethernet rate on the client end from the actual physical interface by introducing a new shim through IEEE defined MAC and PCS layers.

What is FlexE

FlexE Capabilities

Bonding of Ethernet PHYs

  • Combine a group interface to create higher rate clients
  • Support higher bandwidth service

FlexE Bonding 

Sub-rating of Ethernet PHYs

  • Ability to under-fill an interface
  • Ability to match the client or service rate to transport network

FlexE Sub Rating

Channelization within a PHY or a group of bonded PHYs

  • Aggregate lower rate clients onto an interface
  • Scalable alternative to VLANs
