Generic Framing Procedure (GFP)
GFP Summary
GFP has been standardized to better optimize the transport of Ethernet and
other data services over SONET, taking into account both the pros and cons
of ATM and PPP/HDLC framing mechanisms. As described in this section,
GFP represents a robust mapping mechanism that allows for the mapping
of multiple client-data types into SONET/SDH payload (SPEs). This
technology has been embraced by network equipment and service
providers as it provides an efficient way of providing interoperable
data-services transport over the existing SONET/SDH install base. The
versatility provided by GFP allows SONET/SDH networks to offer transport
services for a multiple of services, as shown in figure below.
