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. It interfaces with the PMEs across the λ-interface, and to the MAC-PHY Rate Matching function using an abstract interface. PAF is an optional function that was defined before 2007 for two IEEE 802.3 interfaces: 2BASE-TL and 10PASS-TS, both of which were Ethernet in the first mile (EFM) copper PHY .
