Embodiment Construction

[0028] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the present invention discloses a passive optical fiber network protocol stack acceleration processing method, the method comprising the following steps:

[0030] Step 1. Copy the message header parsing part of the operation management and maintenance (OAM) protocol stack and send it to the underlying driver layer (drive) or hardware abstraction (HAL) layer.

[0031] Step 2. After the driver layer or the hardware abstraction layer obtains the data, it directly parses the header of the message to know the specific function type of the message.

[0032] Step 3. The driver layer or the hardware abstraction layer judges whether the passive optical network message can directly complete the function at the driver layer. If yes, then jump to step 3.1. If not, then jump to step 4. Among them, the passive optical netwo...

Abstract

The invention discloses a passive optical network protocol stack accelerated processing method which comprises the following steps: a message header parsing part of an operation management and maintenance protocol stack is copied and sent to a drive layer at the bottom; the drive layer directly parses a message header to acquire the specific function type of a message after acquiring data; the drive layer directly processes the passive optical network message and sends a reply message when judging that the passive optical network message can directly complete functions at the drive layer, or the drive layer uploads the passive optical network message to an upper layer for processing; and the drive layer directly replies when judging that the message is a specific unknown message and directly discards the message when judging that the message is an unsupported message. A data message is coarsely parsed by the bottom drive layer or a hardware abstraction layer, messages which can be completed by the bottom drive layer are directly processed, unnecessary message transmission is greatly reduced, and the work efficiency of operation management and data maintenance is enhanced.

Description

technical field [0001] The invention provides a passive optical fiber network protocol stack acceleration processing method. Background technique [0002] The existence of the traditional network management protocol stack is often established for the management of optical network unit (Optical Network Unit, ONU) equipment. This kind of protocol stack generally adopts a slow protocol, and there are not many packets generated during management. [0003] But relatively speaking, the protocol stack of Passive Optical Network (PON) is different. Although the positioning of the protocol stack is the network management protocol stack, it also includes the control of the PON module to maintain the PON For the continuous communication of the link, it can be said that the PON protocol stack is not only an upper layer pure data management module, but also includes a lot of hardware management, which is a key new protocol stack. [0004] The current mode of processing this type of data...
