Generic framing procedure(GFP) is a new brand of data-packet transmitting protocol on synchronous digital hierarchy(SDH), as well as on optical transport network(OTN).

通用成帧协议（GFP）不仅是光同步数字传输网上的传输协议，而且是光传输网上的新型数据包传输协议，它具有简单、多协议适配等优点。

With the media streaming transporting, the media source incise the media data, form the RTP framing packet, which is the starting point in realizing the real-time streaming transport.

在媒体流传输过程中，首先，数据源对媒体数据的切割、形成RTP封装包是实现实时流式传输的起点。
