A GFP frame filter is provided to filter GFP frame data based on extracted GFP header data. The header data comprises EXI, PTI, and UPI fields. The header data can also comprise a generic header that can be customized to provide additional GFP frame filtering applications. The GFP frame filter comprises a plurality of programmable filters arranged to process GFP header data in parallel according to various programmable filter configurations. The plurality of programmable filters can be configured to operate in conjunction in a particular sequence.

GFP frame filter

A system and method of delineating GFP data. The GFP framer comprises a candidate generator for generating an array of core header candidates from a data word received on a data bus, a candidate processor for generating a plurality of candidate tours and a frame delineator for identifying a candidate tour as an active tour and delineating the boundaries of the GFP frames defined by the active tour. Each core header candidate defines a reference position of one of the plurality of candidate tours. Each of the plurality of candidate tour comprises a record of core header positions for a series of GFP frames from the data word.
