Detailed Description

In order to make those skilled in the art better understand the technical solution of the present disclosure, the following describes in detail a message transmission control method, a message generation method, a message transmission method, a configuration method, an electronic device, and a computer readable medium provided in the embodiments of the present disclosure with reference to the drawings.

Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, but which may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Embodiments of the present disclosure and features of embodiments may be combined with each other without conflict.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

The inventor of the embodiment of the present disclosure finds that, in the prior art, in order to ensure the flexibility of OAM, a processor needs to spend a large amount of resources to process and store a complete OAM message, resulting in very low OAM sending performance; in order to ensure the sending performance of OAM, the OAM message format needs to be solidified, resulting in poor flexibility and extensibility. The existing software and hardware implementation of OAM message transmission can not ensure the OAM transmission performance and flexibility at the same time.

In view of the above, in a first aspect, with reference to fig. 1, an embodiment of the present disclosure provides a method for controlling packet transmission, including:

in step S110, reading trigger configuration information of a current session from a trigger configuration space of the current session, where an on-chip storage device includes a plurality of trigger configuration spaces, each trigger configuration space corresponds to a session, and the current session is one of the plurality of sessions;

in step S120, determining whether the current session needs to send a message according to the trigger configuration information;

in step S130, under the condition that the current session needs to send a packet, the session identifier of the current session and the packet information of the packet that the current session needs to send are written into the on-chip storage device.

In 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 an on-chip storage device, and the trigger configuration information of the sessions in the trigger configuration space is configured by software running on an onboard Micro Control Unit (MCU).

In the embodiment of the present disclosure, the protocol type of each session is configurable, and the embodiment of the present disclosure does not make any special limitation on the configurable protocol type. For example, protocol types include, but are not limited to: ethernet OAM, Multi-Protocol Label Switching Transport Profile (MPLS _ TP), OAM, Bidirectional Forwarding Detection (BFD). In addition, the embodiment of the disclosure also supports a customized OAM protocol type, and the customized OAM protocol type can be used for protocol extension. It should be noted that, in the embodiment of the present disclosure, when a session configures a customized OAM protocol type, the session may send any type of message.

In the embodiment of the present disclosure, each session can send an OAM message of multiple message types, and the embodiment of the present disclosure does not specially limit the message types. For example, the Packet type may include Connectivity detection (CV), BFD, Client Signal Failure (CSF), Automatic Protection Switching (APS), Alarm Indication (AIS), etc., and may also be 2544 Packet, Link-State Packet (LSP) Packet, etc. In addition, the embodiment of the disclosure also supports a user-defined message type, and the user-defined message type can be used for extension.

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

The embodiment of the present disclosure does not make any special limitation on 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 may be accessed in a polling manner, and it is determined whether a session needs to send a message. It should be noted that, in the embodiment of the present disclosure, in the process of accessing the trigger configuration spaces in the on-chip storage device one by one, two trigger configuration spaces before and after accessing are accessed, and whether a time interval exists when a message needs to be sent is determined, so that burst traffic caused by sending a message at the same time by multiple sessions can be avoided, and thus the burst traffic is effectively smoothed; and the trigger configuration space in the on-chip storage equipment is accessed one by one to judge whether the message needs to be sent or not, and the message can be sent with high precision.

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 a session number of the session, and the hardware logic reads the trigger configuration space of the session one by one through the session numbers of the plurality of sessions. As an optional implementation manner, the session identifiers of the multiple sessions are session numbers which are numbered continuously from 0, the hardware logic first accesses a trigger configuration space corresponding to the session number 0, and determines whether the session of the session number 0 needs to send a message; and then adding 1 to the session number, accessing the trigger configuration space corresponding to the session number 1, and judging whether the session of the session number 1 needs to send messages … … in sequence until accessing the trigger configuration space corresponding to the last session number.

As an optional implementation manner, the on-chip storage device includes a First-in First-out (FIFO) memory, and in step S130, the hardware logic writes the session identifier of the current session and the message information of the message that needs to be sent by the current session into the FIFO memory in the on-chip storage device.

In the embodiment of the present disclosure, each session can simultaneously send messages of multiple message types, that is, each session can support multiple message types. When the hardware logic accesses the trigger configuration space of the session, messages of multiple message types supported by the session can be triggered completely, can be triggered partially, and can not be triggered completely. The embodiment of the present disclosure is not particularly limited in this regard. In the embodiment of the present disclosure, the trigger configuration information configured in the trigger configuration space of the on-chip storage device includes a message type supported by a session and trigger conditions of messages of various message types. And the hardware logic respectively judges whether the triggering conditions of the messages of various message types are met by accessing the triggering configuration space of the session, judges that the session does not need to send the messages when the triggering conditions of the messages of various message types are not met, and judges that the session needs to send the messages otherwise.

Accordingly, in some embodiments, the trigger configuration information includes at least one packet type supported by the current session, and referring to fig. 2, step S120 includes:

in step S121, whether the trigger condition of the message of each message type is satisfied is determined according to the trigger configuration information;

under the condition that the triggering condition of at least one message in the message types is met, judging that the current session needs to send the message;

and under the condition that the triggering conditions of the messages of the multiple message types are not satisfied, judging that the current session does not need to send the messages.

In the embodiment of the present disclosure, after an OAM connection is established, OAM entities at two ends may send OAM Protocol Data Units (PDUs) at certain time intervals as a period to detect whether the OAM connection is normal. In the embodiment of the present disclosure, a sending period of messages of various message types supported by a session is configured in a trigger configuration space of each session. In the same session, the sending periods of the messages of different message types may be the same or different, and this is not particularly 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, whether the messages of various message types meet the trigger condition is determined according to whether the current time meets the sending cycle of the messages of various message types. Only when the time of the triggering configuration space of the hardware logic access session meets the sending period of the message, the message information of the message with the sending period meeting is written into the on-chip storage device through the step S130, and the message is further assembled and transmitted by the hardware logic, so that the sending periods of the messages of various message types are ensured.

Correspondingly, in some embodiments, the trigger configuration information further includes transmission periods of messages of various message types, and referring to fig. 3, step S121 includes:

in step S1211, it is determined whether a transmission period of the message type is satisfied;

under the condition that the sending period of the message type is met, judging that the triggering condition of the message type is met;

and under the condition that the sending period of the message type is not satisfied, judging that the triggering condition of the message type is not satisfied.

The embodiment of the present disclosure does not have to be specially limited to how to execute step S211 to determine whether the transmission period of the message satisfies. For example, when a reference pulse (3.33ms) corresponding to the transmission cycle of the message arrives according to the reference pulse of the timer, it indicates that the transmission cycle of the message is satisfied.

The embodiment of the disclosure also supports the sending of the first packet. It should be noted that, at the initial time of the process of periodically sending the message, the first time sending the message is the first packet sending. In the embodiment of the present disclosure, when a message of a certain message type is sent as a first packet, it is determined that the trigger condition of the message type is satisfied, and the message information of the message whose sending cycle 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.

Accordingly, referring to fig. 3, in some embodiments, before step S1211, step S121 further includes:

in step S1212, it is determined whether the packet of the packet type is sent as the first packet;

if the message of the message type is not the first packet, step S1211 is executed.

In some embodiments, referring to fig. 3, before step S1212, step S121 further includes:

in step S1213, it is determined whether the transmission condition of the message type is satisfied;

executing step S1212 if the sending condition of the packet type is satisfied;

The embodiment of the present disclosure does not make any special limitation on how to determine whether the sending condition of the message is satisfied. For example, whether the sending condition of the message is satisfied can be judged according to monitoring of the link performance, and when packet loss, time delay, jitter and the like of the link need to be measured and various flows need to be counted, the sending condition of the message is judged to be satisfied; whether the sending condition of the message is met or not can be judged according to the link fault detection and alarm, and the sending condition of the message is judged to be met when the link fault needs to be detected; whether the sending condition of the message is met can be judged according to the loop test of the link, and when the loop exists in the link, the sending condition of the message is judged to be met.

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, where the sending enable information can define whether the sending enable of the session is enabled, and the hardware logic determines whether the session supports sending a message and whether the session supports sending a message type by determining whether the sending enable is enabled.

Accordingly, in some embodiments, the trigger configuration information further includes transmission enabling information of the current session, and referring to fig. 3, before step S1213, step S121 further includes:

in step S1214, determining whether the transmission enable of the current session is turned on according to the transmission enable information;

in a case where the transmission of the current session is enabled to be turned on, performing step S1213;

In the embodiment of the disclosure, the sending enable of the current session comprises global enable, and the global enable is started to indicate that the current session supports sending a message; the sending enable further comprises a plurality of session enables, each session enable corresponds to one message type, for example, the session enable comprises CV/BFD enable, CSF enable, APS enable, etc., and the session enable opens the message type corresponding to the current session support.

In the embodiment of the present disclosure, the hardware logic respectively determines whether the messages of various message types satisfy the trigger condition by accessing the trigger configuration space of the session, and determines that the session needs to send the message when the trigger condition of at least one message type of the message is satisfied. At this time, the message meeting the trigger condition is the message that the session needs to send. It should be noted that, there may be one or more message types of messages to be sent in the same session.

It should be noted that, in the embodiment of the present disclosure, when a message is sent, some information generally needs to be carried in the message, for example, the CSF message carries the signal failure reason information sf _ replay. As an optional implementation manner, the hardware logic in the embodiment of the present disclosure generates and transmits a message according to a protocol type of a session, a message type of a message that needs to be sent by the session, and information that the message needs to carry.

Correspondingly, in some embodiments, the packet that the trigger condition satisfies is the packet that the current session needs to send, the trigger configuration information further includes the protocol type of the current session and information to be carried of the packets of various packet types, and the packet information includes the protocol type of the current session, the packet type of the packet that the trigger condition satisfies, and the information to be carried of the packet that the trigger condition satisfies.

In the embodiment of the present disclosure, the hardware logic accesses the trigger configuration space in the on-chip storage device one by one, and determines whether each session needs to send a packet. The embodiment of the present disclosure does not make any special limitation on how to access the trigger configuration space in the on-chip storage device one by one. As an optional implementation manner, the trigger configuration space in the on-chip storage device may be accessed in a polling manner, and whether the session needs to send a message is determined.

Accordingly, referring to fig. 4, in some embodiments, the message transmission control method further includes:

in step S140, according to the configured number of sessions that need to be polled and the polling granularity, reading the trigger configuration information of the next session from the trigger configuration space of the next session of the current session to implement polling on a plurality of sessions, where the polling granularity represents a time interval between two sessions before and after polling.

It should be noted that, in the embodiment of the present disclosure, polling on multiple sessions is performed periodically, and multiple sessions that need to be polled are polled in each polling period. The time interval between two polling operations in the same session can be ensured to be a polling period, so that the sending precision is ensured. For example, the session identifiers of the multiple sessions are session numbers which are numbered continuously from 0, when a polling cycle arrives, the hardware logic first accesses a trigger configuration space corresponding to the session number 0, and judges whether the session of the session number 0 needs to send a message; then adding 1 to the session number, accessing the trigger configuration space corresponding to the session number 1, judging whether the session of the session number 1 needs to send a message … …, and so on until all the trigger configuration spaces corresponding to the session numbers are accessed; the session number to be accessed is then reset to 0 and when the next polling period comes, polling is initiated again starting from session 0.

In the embodiment of the present disclosure, the hardware logic polls a plurality of sessions according to the configured number of sessions that need to be polled and the polling granularity, so that polling moments of the plurality of sessions in one polling period can be uniformly distributed in the polling period, thereby effectively smoothing burst traffic.

As an alternative embodiment, the hardware logic initiates polling for multiple sessions each time a reference pulse of the timer arrives, i.e. the polling period is 3.33 ms.

reference pulse period (1) number of sessions requiring polling x polling granularity

Referring to fig. 4, the packet transmission control method further includes:

in step S150, polling of a plurality of said sessions is initiated in response to a reference pulse.

In the embodiment of the disclosure, the hardware logic initiates polling on a plurality of sessions in response to the reference pulse, which can ensure that the time interval of two polling operations before and after each session is 3.33ms, and can make the error reach nanosecond level; the reference pulse is used as a polling period, so that when the sending period of any message type in a session is met, hardware logic initiates polling on a plurality of sessions, and the sending period of the message can be ensured.

In order to make the technical solutions provided by the embodiments of the present disclosure more clearly understood by those skilled in the art, the technical solutions provided by the embodiments of the present disclosure are described in detail below by specific examples:

example one

In the first embodiment, all sessions are polled, and whether the current session needs to send a message is determined according to the timer and the alarm state. In this embodiment, the current session can send an ethernet OAM message, a TP1731 message, an bfd message, and a message with a custom message type. When the current conversation needs to send the message, the hardware logic writes the basic information of the message needing to be sent into the on-chip storage device, and the basic information of the message needing to be sent comprises the conversation number of the current conversation and the message type of the message needing to be sent.

In the first embodiment, the reference pulse (3.3ms) is used as the polling period. When the reference pulse of the timer comes each time, polling is initiated from the session 0, so that the interval between two polling times before and after each session is ensured to be 3.3ms, the error is in a nanosecond level, and the sending precision is improved.

In the first embodiment, for a scenario with a transmission period of 10ms, 100ms, 1s, etc., since the transmission period is an integer multiple of 3.33ms, the corresponding reference pulse and 3.33ms pulse are pulled high at the same time and last for the whole polling period.

In this embodiment one, the polling granularity and the number of polling sessions are configurable. For example, if the primary frequency is 1Ghz, 128K sessions are used totally, and only 30K sessions in a scene are used, the polling granularity is configured as 100ns, the number of polls is configured as 30K, when a reference pulse (3.3ms) arrives, polling starts from session 0, polls session 1 after 100ns, polls session 2 after 100ns, until the session 30K finishes polling, and the polling time instants of the 30K sessions are uniformly distributed in a time range of 3 ms. Therefore, the burst flow can be effectively smoothed and uniformly distributed no matter how many sessions transmit messages and no matter how many message transmission periods configured by each session transmit messages.

Example two

In the second embodiment, the hardware logic reads message information of a message to be sent from the on-chip storage device, where the message information of the message to be sent includes a session number of a session where the message is to be sent and a message type of the message to be sent; reading package configuration information and a message template according to a session number of a session needing to send a message; then replacing corresponding fields in the message template according to the package configuration information and the message type of the message to be sent, and assembling to generate a message to be transmitted; and writing the message to be transmitted into a cache.

In the second embodiment, messages of different message types in the same session share the same message template, so that the flexibility is ensured, and the cached storage resources and the CPU processing resources are saved. The message template comprises message header contents such as DA, SA, VLAN, tag, ACH and the like, and other user-definable contents. In the second embodiment, the message template is configured according to the cv/bfd message format by default. When a message to be transmitted is generated by assembling, after a message template is read from a cache, if the message to be transmitted is a cv message, the fields of rdi, seqnum and lm _ cnt are replaced; if the message to be sent is bfd message, replacing the fields of diag, sta and checksum; if the message is other messages, fields such as version, opcode, flags, TLV and the like are replaced.

In the second embodiment, the global configuration field in the message template is replaced according to the protocol type and the global configuration, and includes a TC value, a channeltype value, a mel value, and the like of the innermost label.

In the second embodiment, if the message to be sent is a message of a self-defined message type, the message template field is not replaced, and the message template configured by the CPU is directly read as the message to be transmitted, so that the expandability of the message is ensured.
