The Generic Framing Procedure

(GFP) provides an efficient,

scalable and unified mode of

transport for corporate LAN, SAN,Internet access, and other data

transfer applications.

GFP minimizes system bandwidth

requirements. It allows multipleprotocols from different ports or

links to share the same transport

path, resulting in more efficient

use of available bandwidth.

Generic Framing Procedure (GFP)

International standard

Adopted by both ANSI and ITU-T.

Framing protocol to replace framing of native Ethernet protocol.

Efficient framing protocol with a small, fixed overhead Rate adaptation function

Essential for rate-guaranteed services

Efficient OA&P capabilities included

Scales well to higher transport rates

X.86 (LAPS/X.25/HDLC-based) alternatives limited in these areas

Two modes

GFP-F: Frame-based packet-aware, optimized for packet-basedservices. Used for Ethernet services.

GFP-T: Transparent - for 8B/10B encoded protocols with high delaysensitivity. Used for SAN services.

Inverse multiplexing over SONET Logical grouping of non-contiguous SONET channels to create a Virtual

Trunk for transporting data traffic (VCG=virtual concatenation group)

21 STS-1 for full-rate GbE transport

Compatible with standard SONET network infrastructures Only endpoints need to be virtual concatenation aware

Individual SONET channels in a VCG can be groomed onto

available bandwidth and transported independently through the

SONET network Differential delay compensation for diverse paths through the

SONET network

Virtual Concatenation (VCAT)

Eliminates SONET granularity limitations,enabling efficient data transport!
