The existing software and hardware implementations of OAM packet transmission cannot simultaneously guarantee the OAM transmission performance and flexibility.

In view of this, in the first aspect, referring to FIG. 1 , an embodiment of the present disclosure provides a packet transmission control method, including:

In step S110, the trigger configuration information of the current session is read from the trigger configuration space of the current session, wherein the on-chip storage device includes a plurality of trigger configuration spaces, each of the trigger configuration spaces corresponds to a session, and the The current session is one of a plurality of said sessions;

In step S130, when the current session needs to send a message, the session identifier of the current session and the message information of the message to be sent by the current session are written into the on-chip storage device.

In the embodiment of the present disclosure, a trigger configuration space for storing the trigger configuration information of each session is allocated to a plurality of sessions in the on-chip storage device, and the trigger configuration information of the session in the trigger configuration space is controlled by the on-board microcontroller unit (MCU, Software configuration running on the Microcontroller Unit).

In the embodiment of the present disclosure, the protocol type of each session is configurable, and the embodiment of the present disclosure does not specifically limit the configurable protocol type. For example, the protocol types include but are not limited to: Ethernet OAM, Multi-Protocol Label Switching Transport Profile (MPLS_TP, Multi-Protocol Label Switching Transport Profile) OAM, and Bidirectional Forwarding Detection (BFD). In addition, the embodiment of the present disclosure also supports a custom OAM protocol type, and the custom OAM protocol type can be used for protocol extension. It should be noted that, in this embodiment of the present disclosure, when a user-defined OAM protocol type is configured for a session, the session can send any type of packets.

In the embodiment of the present disclosure, each session can send OAM packets of multiple packet types, and the embodiment of the present disclosure does not specifically limit the packet types. For example, the packet types may include Connectivity Verification (CV, Connectivity Verification), BFD, Client Signal Fail (CSF, Client Signal Fail), Automatic Protection Switching (APS, Automatic Protection Switching), Alarm Indication (AIS, Alarm Indication Signal), etc. , and may also be a 2544 message, a Link-State Packet (LSP, Link-State Packet) message, and the like.

In the embodiment of the present disclosure, the hardware logic accesses the trigger configuration space in the on-chip storage device one by one to determine whether each session needs to send a message. Corresponding to each session, the trigger configuration information of the session is read through steps S110 to S130, according to the trigger configuration information, it is judged whether the session needs to send a message, and when a message needs to be sent, the session identifier and The message information of the message to be sent by the session is written into the on-chip storage device, so that the hardware logic further assembles and transmits the message according to the session identifier and message information of the session that needs to send the message in the on-chip storage device. The current session described in steps S110 to S130 is the session corresponding to the trigger configuration space currently accessed by the hardware logic.

This embodiment of the present disclosure does not specifically limit how to access the trigger configuration space in the on-chip storage device one by one. For example, the trigger configuration space in the on-chip storage device can be accessed in a polling manner, and it is determined whether the session needs to send a message. It should be noted that, in the embodiment of the present disclosure, since in the process of accessing the trigger configuration spaces in the on-chip storage device one by one, there is a time interval between accessing the two trigger configuration spaces before and after and judging whether a message needs to be sent, so multiple The session sends packets at the same time to cause burst traffic, thereby effectively smoothing the burst traffic; accessing the trigger configuration space in the on-chip storage device one by one to determine whether the packet needs to be sent can also achieve high-precision packet sending.

The embodiment of the present disclosure does not specifically limit the specific form of the session identifier of the session. For example, the session identifier may be the session number of the session, and the hardware logic reads the trigger configuration space of the sessions one by one through the session numbers of the multiple sessions. As an optional implementation manner, the session identifiers of multiple sessions are session numbers consecutively numbered from 0, and the hardware logic first accesses the trigger configuration space corresponding to session number 0 to determine whether the session of session number 0 needs to send a message; Then add 1 to the session number, access the trigger configuration space corresponding to session number 1, and determine whether the session of session number 1 needs to send a message... and so on, until the trigger configuration space corresponding to the last session number is accessed.

As an optional implementation manner, the on-chip storage device includes a first-in, first-out (FIFO, First InputFirst Output) memory, and in step S130, the hardware logic compares the session identifier of the current session and the message to be sent by the current session. The message information is written into the FIFO memory in the on-chip storage device.

In the message transmission control method provided by the embodiment of the present disclosure, a trigger configuration space for storing trigger configuration information of each session is allocated to a plurality of sessions in the on-chip storage device, and the hardware logic is configured by the on-board micro-control unit by reading The software running on the device configures the trigger configuration information in the trigger configuration space to determine whether each session needs to send a message. The hardware logic can further assemble the message according to the session identifier and message information of the session that needs to send the message in the on-chip storage device. and transmission, so that the processor does not need to spend a lot of resources to process and store the complete message, and the performance is guaranteed; at the same time, in the embodiment of the present disclosure, the protocol type of each session can be configured, and each session can send multiple messages at the same time. It supports custom protocol types and packet types, ensuring flexibility and scalability; by accessing the trigger configuration space in the on-chip storage device one by one to determine whether a packet needs to be sent, it can also effectively smooth burst traffic and achieve high-precision transmission. message.

In the embodiment of the present disclosure, each session can simultaneously send packets of multiple packet types, that is, each session can support multiple packet types. When the hardware logic accesses the trigger configuration space of a session, the packets of multiple packet types supported by the session can be all triggered, partially triggered, or not triggered at all. This embodiment of the present disclosure makes no special limitation on this. In the embodiment of the present disclosure, the trigger configuration information configured in the trigger configuration space of the on-chip storage device includes the packet types supported by the session and trigger conditions for packets of various packet types. By accessing the trigger configuration space of the session, the hardware logic determines whether the trigger conditions of the packets of various packet types are met. When the trigger conditions of the packets of multiple packet types are not met, it is determined that the session does not need to send packets. message, otherwise it is determined that the session needs to send a message.

In the embodiment of the present disclosure, after the OAM connection is established, the OAM entities at both ends will periodically send OAM protocol data units (PDUs, Protocol Data Units) at certain time intervals to detect whether the OAM connection is normal. If the OAM PDU sent by the peer OAM entity is not received within the time, it is considered that the OAM connection is interrupted. In the embodiment of the present disclosure, the trigger configuration space of each session is configured with the sending period of packets of various packet types supported by the session. Wherein, in the same session, the sending period of packets of different packet types may be the same or different, which is not specifically limited in this embodiment of the present disclosure. As an optional implementation manner, when the hardware logic accesses the trigger configuration space of the session, it is judged whether the packets of various packet types meet the triggering conditions according to whether the current moment satisfies the transmission period of the packets of various packet types. Only when the moment when the hardware logic accesses the trigger configuration space of the session meets the sending period of the message, the message information of the message whose sending period is satisfied is written into the on-chip storage device through step S130, and the message is further assembled and transmitted by the hardware logic. , thereby ensuring the sending period of various types of packets.

For example, according to the reference pulse (3.33ms) of the timer, when the reference pulse corresponding to the sending period of the message arrives, it means that the sending period of the message is satisfied.

This embodiment of the present disclosure also supports sending the first packet. It should be noted that, at the beginning of the process of periodically sending a message, the first time a message is sent is the first packet sending.

In step S1213, it is judged whether the sending condition of the message of the message type is satisfied;

In the case that the sending condition of the message of the message type is satisfied, step S1212 is performed;

In the case that the sending condition of the message of the message type is not satisfied, it is determined that the triggering condition of the message of the message type is not satisfied.

Satisfied; it can also judge whether the transmission conditions of the packets are satisfied according to the link failure detection and alarm, and determine whether the transmission conditions of the packets are satisfied when the link failure needs to be detected; it can also be determined according to the loop test of the link It is judged whether the sending conditions of the packets are satisfied. When it is necessary to check whether there is a loop in the link, it is judged that the sending conditions of the packets are satisfied.

In the embodiment of the present disclosure, the software running on the onboard MCU further includes sending enable information in the trigger configuration information configured in the trigger configuration space of the session. The sending enable information can define whether the sending enable of the session is enabled, and the hardware logic Determine whether the session supports sending packets and the type of packets that the session supports by judging whether the sending enable is enabled.
