Description
Technical Field
The invention relates to the field of communication, in particular to a method and a system for processing an up cfm message and network data exchange equipment.
Background
Oam (Operation, Administration and Maintenance) technology in the communication field relates to the generation and termination of Up cfm (Up Connectivity Fault Management) messages in cfm (Connectivity Fault Management) messages. Of which cfm is a network-level ethernet oam technology.
In a communication network, the Ethernet oam technology can effectively improve the management and maintenance capability of the Ethernet and ensure the stable operation of the network. The service layer ethernet oam technology cfm is mostly applied to an access convergence layer of a network, and is used for monitoring the connectivity of the whole network and locating the connectivity fault of the network. The cfm messages are divided into Down cfm (downlink Connectivity fault management) messages and up cfm messages, and the up cfm messages are initiated and terminated at up mep (inward maintenance endpoint). mep refers to the maintenance end point of the maintenance domain, which determines the scope and boundary of the maintenance domain. The maintenance end points have directionality and are divided into an outward maintenance end point (downmep) and an inward maintenance end point (up mep). The direction of the maintenance end point indicates the location of the maintenance domain relative to the port. The outward maintenance end point sends out the message through the port where the outward maintenance end point is located, and the inward maintenance end point does not send out the message through the port where the inward maintenance end point is located, but sends out the message through other ports on the equipment.
At present, for the generation and termination of oam messages, except that an up cfm message needs to generate and terminate at an up mep, other oam messages include mpls-tp (Multi-Protocol Label Switching-Transport Architecture) oam messages, bfd (Bidirectional Forwarding Detection) messages and down cfm messages, which are all generated and initiated from a main control board and sent to an opposite-end node main control board through an NNI (network network network interface) line for termination, and only the up cfm message needs to be generated and terminated at the up mep line card, but a set of message generation termination mechanism is generated at the up mep alone, which complicates the hardware and software design of the whole system and consumes more resources, and also brings restriction to line cards for development.

Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
The first embodiment is as follows:
this embodiment provides a method for processing an up cfm packet, please refer to fig. 1, which includes:
step S101: a main control board of the first network data exchange equipment generates a first inward connectivity fault management message according to the configuration parameters of the first inward connectivity fault management message;
step S102: and the first network data switching equipment sends the first inward connectivity fault management message to second network data switching equipment of the opposite terminal.
In this embodiment, the network data switching device may be a bearer PTN network access layer device or the like.
In step S101, the main control board may generate a first inward connectivity fault management packet through the processor and the packet processing circuit, for example, the processor configures parameters of the first inward connectivity fault management packet, and the packet processing circuit generates the first inward connectivity fault management packet according to the configured parameters. Of course, the processor itself may generate the upcfm message according to the configuration parameters, and the upcfm message generated by the processor is generally a slow-speed upcfm message. The message processing circuit may be an FPGA (Field-Programmable Gate Array), a PLA (Programmable logic Array), or the like.
Further, the step S102 may further include the following steps, please refer to fig. 2:
step S201: the main control board of the first network data exchange equipment sends the first inward connectivity fault management message to an inward maintenance end line card on the first network data exchange equipment;
step S202: the inward maintenance end line card receives and processes the first inward connectivity fault management message and then sends the first inward connectivity fault management message to the main control board;
step S203: and the main control board of the first network data switching equipment sends the first inward connectivity fault management message from the inward maintenance end point line card to the second network data switching equipment.
In this embodiment, the main control board of the first network data exchange device may not only generate the up cfm packet, but also complete the termination processing of the up cfm packet. For example, after the first network data switching device receives the second inward connectivity fault management message sent by other network data switching devices except the first network data switching device, the main control board terminates the second inward connectivity fault management message.
Further, the step of receiving, by the first network data switching device, the second inward connectivity fault management message may specifically include the following steps, please refer to fig. 3:
step S301: the main control board of the first network data exchange equipment receives the second inward connectivity fault management message;
step S302: the main control board sends the second inward connectivity fault management message to an inward maintenance end line card on the first network data switching equipment;
step S303: and the inward maintenance end point line card receives and processes the second inward connectivity fault management message and then sends the second inward connectivity fault management message to the main control board on the first network data exchange equipment.
In the above steps S201 to S203 and steps S301 to S303, the main control board is involved in receiving, sending and processing the first up cfm message and the second up cfm message. That is, after receiving the up cfm packet, the main control board needs to process the up cfm packet, for example, terminate the up cfm packet, and send the up cfm packet to the inward maintenance end line card or the second network data switching device. In order to facilitate the main control board to determine the processing mode of the up cfm message, a forwarding direction identifier may be set for the first up cfm message and the second up cfm message, and the following setting may be specifically adopted:
before step S201, that is, before the main control board of the first network data switching device sends the first inward connectivity fault management packet to the inward maintenance end line card on the first network data switching device, the method further includes: setting a first internal forwarding pointing identifier for the first internal connectivity fault management message; the main control board of the first network data switching device sending the first inward connectivity fault management message to an inward maintenance end line card on the first network data switching device includes: the main control board of the first network data exchange equipment judges whether the first inward connectivity fault management message contains a first inward forwarding pointing identifier, and if so, the first inward connectivity fault management message is sent to an inward maintenance endpoint line card on the first network data exchange equipment; after the inward maintenance end point line card receives the first inward connectivity fault management message, the processing of the first inward connectivity fault management message comprises the following steps: removing the first internal forwarding pointing identifier; the method for sending the first inward connectivity fault management message from the inward maintenance end point line card to the second network data switching equipment by the main control board of the first network data switching equipment comprises the following steps: and the main control board of the first network data exchange equipment judges whether the first inward connectivity fault management message contains a first inward forwarding pointing identifier or not, and if not, the first inward connectivity fault management message is sent to the second network data exchange equipment. The first internal forwarding direction identifier may use a separate identifier, or may borrow an attribute parameter existing in the first up cfm packet, for example, an etype (ethernet type) field value of the first up cfm packet. When the main control board just generates a first up cfm message, the etype domain value is set to a value required by the internal link transmission of the first network data exchange device, for example, 0xfefe, where the etype domain value is 0xfefe, which is a first internal forwarding direction identifier, and after the main control board sends the first up cfm message to the inward maintenance endpoint line card, the inward maintenance endpoint line card modifies the etype domain value thereof to a standard etype domain value required by the interaction between the first network data exchange device and other network data exchange devices, that is, 0x8902, so that the etype domain value is no longer 0xfefe, that is, the first internal forwarding direction identifier is removed, and then the main control board sends the first up cfm message to the main control board, and after receiving the first up cfm message, the main control board learns that the etype domain value is 0x8902, thereby determining that the first internal forwarding direction identifier is not present in the first up cfm message, and further determining that the first up cfm message needs to be sent to the second network data exchange device at the opposite end, rather than forwarding it to the inbound maintenance endpoint line card.
In step S202, the processing, by the inward maintenance endpoint line card, of the received first up cfm further includes: and modifying the correlation domain values of the LM (frame loss measurement) and DM (frame delay measurement) functions in the first up cfm message to complete the LM and DM functions of the up cfm message.
In step S301, the sending, by the main control board of the first network data switching device, the second inward connectivity fault management packet to the inward maintenance end line card on the first network data switching device includes: the main control board of the first network data exchange equipment judges whether the second inward connectivity fault management message contains a second inward forwarding pointing identifier or not, and if not, the second inward connectivity fault management message is sent to an inward maintenance endpoint line card on the first network data exchange equipment; after the inward maintenance end point line card receives the second inward connectivity fault management message, the processing of the second inward connectivity fault management message comprises the following steps: setting a second internal forwarding pointing identifier for the second internal connectivity fault management message; after the inward maintenance end point line card sends the second inward connectivity fault management message to the main control board, the step of terminating the second inward connectivity fault management message by the main control board includes: and the main control board of the first network data exchange equipment judges whether the second inward connectivity fault management message contains a second internal forwarding pointing identifier, and if so, executes the final processing of the second inward connectivity fault management message. The second internal forwarding direction identifier may use a separate identifier, or may borrow an attribute parameter existing in the second up cfm packet, for example, an etype (ethernet type) field value of the second up cfm packet. Further, the etype field value of 0xfeff may be set to the second internal forwarding direction identifier. If the etype domain value in the second up cfm message is the standard etype domain value required by the interaction between the first network data exchange device and other network data exchange devices, namely 0x8902, the main control board can judge that the second up cfm message does not include the second internal forwarding pointing identifier through the etype domain value, so that the second up cfm message is determined to be processed to be forwarded to the inward maintenance end point line card instead of being processed to be ended. After the main control board sends the second up cfm message to the inward maintenance end point line card, the inward maintenance end point line card modifies the etype domain value of the second up cfm message into a value required by the internal link transmission of the first network data exchange device, such as 0xfeff, namely, a second internal forwarding direction identifier, and then sends the value to the main control board, and the main control board obtains that the etype domain value is 0xfeff after receiving the second up cfm message, so that the second inward connectivity fault management message is judged to contain the second internal forwarding direction identifier, and the second up cfm message is determined to be processed as a final process instead of being forwarded to other network data exchange devices.
Example two:

Example five:
in this embodiment, a network data exchange device in the present invention is represented by a PTN-bearing network access layer device, please refer to fig. 9 and 10, fig. 9 is a schematic flow diagram of the method for processing an upcfm message provided in the embodiment of the present invention, fig. 10 is a schematic structural diagram of a PTN-bearing network access layer device a and a PTN-bearing network access layer device B in the method for processing an up cfm message provided in the embodiment of the present invention, and the method specifically includes the following steps:
step S901, first, a CPU and an FPGA of a main control board carrying the PTN network access layer device a generate an up cfm message. In order to identify the up cfm message by the exchange chip, defining the etype domain value of the up cfm message as 0xfefe as a first internal forwarding pointing identifier. The up cfm message and the down cfm message are generated by adopting a CPU and an FPGA, and the difference is that etype domain values of the carried messages are different.
The main control board may generate other oam messages, such as bfd message, mpls-tp oam message, and the like, besides the up cfm message and the down cfm message. bfd contains information such as cycle, my descriptor, your descriptor, etc. The mpls-tp oam message contains information such as period, meg id and mep id. The down cfm message and the up cfm message contain information such as period, mel, ma id and mep id.
Step S902, the exchange chip of the main control board bearing the PTN network access layer device A identifies an up cfm message with etype of 0xfefe input from the FPGA or the CPU and forwards the message to a corresponding up mep line card. Other oam messages generated by the main control board are directly sent to the NNI line card (network interface line card) through the switching chip, and then sent to the PTN network access layer equipment B at the opposite end through the NNI line card.
