Generic Framing Procedure (GFP) is a multiplexing technique defined by ITU-T G.7041. This allows mapping of variable length, higher-layer client signals over a circuit switched transport network like OTN , SDH / SONET or PDH .
Fundamental to FT is its ability to stop the proliferation [2] of similar but subtly different components, an issue plaguing software engineering, for which programming language constructs (subroutines, classes, or templates/generics) or add-in techniques such as macros and generators failed to provide a practical, scalable solution.

Virtual concatenation leverages the X.86 or Generic Framing Procedure (GFP) protocols in order to map payloads of arbitrary bandwidth into the virtually concatenated container. The Link Capacity Adjustment Scheme (LCAS) allows for dynamically changing the bandwidth via dynamic virtual concatenation, multiplexing containers based on the short ...
A common practice in telecommunications, for example in T-carrier, is to insert, in a dedicated time slot within the frame, a noninformation framing bit that is used for synchronization of the incoming data with the receiver. In a bit stream, framing bits are predictable (do not carry information), and occur at specified positions in the frame ...
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
Other recent SONET/SDH enhancements include Link Capacity Adjustment Scheme (LCAS), and the Generic Framing Procedure (GFP). In conjunction with LCAS and GFP, Virtual Concatenation gives the advantage of splitting the required bandwidth equally among a set number of sub paths called Virtual Tributaries (VT).
OTUk [3] is the section and includes framing, TTI, BIP8 and GCC0 bytes. FEC – The standard FEC code (described in G.975 ) is a Reed–Solomon coding calculated across the payload (OPU) columns. This allows detection and correction of bit errors due to signal impairments during transmission.
