Abstract
Virtualized Synchronous Ethernet systems and methods include, in a network element supporting a plurality of slices over a common Ethernet physical (PHY) connection, determining a common PHY frequency; for a specific slice of the plurality of slices, obtaining a bit-level accurate count (C) over a accumulation window; and determining a client clock for the specific slice based on the common PHY frequency and the bit-level accurate count (C). The systems and methods can include receiving the bit-level accurate count (C) from a second network element for synchronization therewith. The bit-level accurate count (C) over the given accumulation window can be determined utilizing accumulators and the client clock can be determined utilizing Digital Phase Lock Loops (DPLLs).
