PME Aggregation Function
PME Aggregation Function (PAF) is a computer networking mechanism defined in Clause 61 of the IEEE 802.3 standard, which allows one or more Physical Medium Entities (PMEs) to be combined to form a single logical Ethernet link. The PAF is located in the physical coding sublayer (PCS), between the media access control (MAC)-PHY Rate Matching function and the Transmission Convergence (TC) sublayer.
