FLEX Ethernet協(xié)議標(biāo)準(zhǔn)，OIF ABSTRACT: The Flex Ethernet (FlexE) Implementation Agreement 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) the Ethernet PHY rates used to carry FlexE. This can be viewed as a generalization of the Multi-Link Gearbox implementation agreements, removing the restrictions on the number of bonded PHYs (MLG2.0, for example, supports one or two 100GBASE-R PHYs) and the constraint that the FlexE clients correspond to Ethernet rates (MLG2.0 supports only 10G and 40G clients).
