Generic Framing Procedure - GFP

Storage (tGFP)

• ESCON/SBCON

• FC/FICON

• GE

• Infiniband

Packet (fGFP)

• IP/PPP

• Ethernet/MAC

GFP encapsulation

End-end service framing, PM & SP OAM, demarc

SDH/SONET

DWDM/OTN

Virtual concatenation (VC-n-mv)

End-end bandwidth efficiency, QoS, transparency & path OAM

SDH/SONET wrapping (S-wrap)

Global network compatibility, security, reliability, carrier OAM

TDM

VC-n

PDH/Async hierarchy

• Simple multiservice adaptation

• Robust & efficient packet transport

• Interoperable global standard

  • Mapping to SDH, SONET & OTN

• Efficient network resource utilisation

  • Low GFP overhead
  • No over-provisioning with virtual SDH

• TDM QoS, latency & jitter performance

  • Transparent mode has no buffering

• L2 agnostic

  • Supports RPR, other L2 protocols

• Enables network consolidation

  • Converges next-generation services with existing infrastructure investment
