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.

GFP 是一种先进的数据业务适配的通用协议和 映射 技术，通过它可以透明地将各种不同物理层或逻辑链路层信号适配进入SDH 和 OTN。 FP 提供了比其它适配和映射技术 (如pocketover SDH、链路接入协议， 简单数据链路)更高效和更可靠的传输。 一种面向无连接的新型数据链路，对各种业务提供通用的、高效而又简单的封装协议。 GFP 帧分为用户帧和控制帧。 用户帧包含用户数据帧和用户管理帧。 用户数据帧用于装载用户净负荷，用户管理帧用于装载GFP 连接起始点的 …

3.5 Frame-mapped GFP: A type of GFP mapping in which a client signal frame is received and mapped in its entirety into one or more GFP frames. 3.6 Transparent GFP: A type of GFP mapping in which block-coded client characters are decoded and then mapped into a fixed-length GFP frame and may be transmitted immediately without waiting for

2024年9月12日 · GFP通用成帧规范（Generic Framing Procedure）是一种先进的数据业务适配的通用协议和映射技术， 由国际电联ITU-T的G.7041标准定义。 该技术旨在透明地将各种不同物理层或逻辑链路层信号适配进入SDH（同步数字体系）和OTN（光传送网）等高速物理传输通道中。 以下是GFP通用成帧规范的详细解释： GFP提供了比其他适配和映射技术（如PPP over SDH 、LAPS等）更高效和更可靠的传输方式。 它支持固定或可变长度的数据封装，简化了系统的操 …

This edition of ITU-T G.7041/Y1303 consolidates ITU-T G.7041/Y1303 (10/2008) and its Amendment 1 (01/2009).

2002年11月19日 · As its name implies, transparent GFP supports the transparent transport of 8B/10B control characters as well as data characters. This is a primary advantage of transparent GFP over frame-mapped GFP. In addition, frame-mapped GFP incurs the latency associated with buffering an entire client data-frame, while transparent GFP requires only a few ...

2019年3月11日 · 帧映射模式(GFP-F)是一种PDU-oriented数据流模式，它们可以用映射整个帧的适配方式(Frame-Mapped)等接收到一个完整的帧后再进行处理；具有不同长度、属于不同业务的GFP帧可以时分复用到一个更高速率的信道传输。

2023年4月23日 · 通用组帧规程（GFP，Generic Framing Procedure）是一种数据链路层协议，设计用于高速链路，能够承载多种业务并实现对非同步不定长数据包的高效定界。GFP协议的帧结构包括核心帧头（Core Header）和载荷域（Payload ...

The GFP frame format is designed to support both the multiplexing of multiprotocol PDUs as well as the multiplexing of a number of logical virtual links within the data link. Logical virtual links can be used to support different traffic streams with potentially different higher-layer protocols and with different QoS requirements. Two basic GFP ...

A “generic” mechanism to adapt multiple client traffic types as either: •a physical link (Layer 1) client. •a logical data link (Layer 2) client. into a bit synchronous or octet-synchronous transmission channel.
