The Xilinx GFP core provides a fully compliant Generic Framing Procedure solution, enabling next generation Ethernet over SONET and Data over SONET applications.
The Xilinx GFP core solution fully implements the International Telecommunication Union’s Generic Framing Procedure recommendation (G.7041/Y.1303). All protocols defined by the ITU’s Telecommunication Standardization Sector (ITU-T) are supported, including Ethernet, PPP, RPR, GE, Fibre Channel, FICON, ESCON, and DVB-ASI. The GFP core includes the capability to perform end-to-end frame delineation, and supports both client management and data frames. The GFP core can be configured for frame-mapped, transparent, or mixed-mode operation on a per-channel basis, enabling multi-line, multi-service cards and systems in Ethernet-over-SONET or Data-over-SONET applications.
关键特性
- Fully compliant with ITU-T G.7041 GFP recommendation
- Supports frame-mapped, transparent, and mixed-mode operation
- Supports both null and linear frames, enabling one to ten unique channels
- Enables multi-line/multi-protocol MSPP's, i.e. 10x 1-GE => OC-192
- Individually optimized for OC-48 or OC-192 applications
- Supports both client data frames and client management frames
- Supports dynamic reconfiguration, error insertion, and status monitoring via host interface
- Separate MAP and UNMAP cores support unique ingress/egress path requirements
- Utilizes Xilinx standard LocalLink interface for easy integration
- Fully configurable using the Xilinx CORE Generator tools
In addition to supporting all of the features specified by G.7041, the Xilinx GFP solution provides options to facilitate system-level integration and debugging such as error injection on a per-frame basis for all scrambling and CRC functions. With the Xilinx CORE Generator™ tool, the GFP core can be easily configured to support specific system requirements, including individually optimized cores for OC-48 and OC-192 applications. The GFP core is quickly integrated into design environments using Xilinx’s standard LocalLink interface, and operational modes can be controlled through the optional host interface.
