Abstract

The invention discloses a velocity adaptation method, which comprises the following steps: receiving an optical fiber channel (FC) signal, and identifying a primitive signal in the received FC signal; calculating continuously present identical primitive signals in the FC signal, and performing velocity adaptation processing on the FC signal if he number reaches a preset threshold. The invention also discloses a velocity adaptation device and a framing protocol transparent mode (GFPT) device. The technical proposal does not specifically identify the primitive in the FC signal, determines the continuous repetition number of the primitive signal, and performs velocity adaptation processing based on the continuous repetition number to simplify the judge manner of the velocity adaptation signal and greatly reduce the realization complexity. Moreover, the processing method does not relate to the determination of the specific primitive signal type to well support the expansion of the FC protocol in future.

Description

technical field

[0001] The invention relates to the technical field of network data transmission, in particular to a rate adaptation method and device. Background technique

[0002] Fiber channel (Fiber channel, FC) services can be transparently encapsulated into a general framing protocol (GFP) frame by using the general framing protocol transparent mode (GFPT) encapsulation technology, and then through the synchronous digital series (Synchronous DigitalHierarchy, SDH), Synchronous Optical Network (Synchronous Optical Network, SONET) or Optical Transport Network (Optical Transport Network, OTN) for transmission. The position of the FC device on the network is as follows: figure 1 As shown, the signal output by the FC device is transmitted to the GFPT device through the FC interface; after being converted by the GFPT device, it is transmitted through SDH / SONET / OTN. The FC device may be a FC switch, a server, a disk array, etc.; the GFPT device may be a dense wavelength div...
