Description

Message forwarding method, device, equipment and storage medium

Technical Field

The present disclosure relates to the field of network communication technologies, and in particular, to a method, an apparatus, a device, and a storage medium for forwarding a packet.

Background

Since ethernet is by nature a non-deterministic network, in some fields such as industrial automation, automatic driving, and other related fields, the requirement for determinism is high, i.e., even if network traffic is congested, it is necessary to ensure that the delay of high priority traffic is certain.

When network traffic is congested, the bandwidth received by the egress end of the device exceeds the maximum bandwidth that can be borne by the port itself, so that packet loss occurs to the data stream, and thus traffic with high priority is lost and delay is uncertain.

In the related art, a device supporting QoS (Quality of Service) can be divided into a plurality of queues at an egress end, and the egress queues are scheduled in absolute priority, and enter different queues through a priority field in a message, thereby ensuring that a high-priority message enters the egress end first. However, the priority policy depends on the priority field of the packet to perform rough classification, which easily causes packet loss of the packet stream due to unreasonable absolute priority scheduling for the high-priority packet stream, and thus it is difficult to ensure that the delay of the high-priority traffic is determined in an actual application scenario, and the priority policy cannot be applied to an ethernet environment with a high requirement on real-time data transmission.

Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more clearly and completely apparent, the technical solutions in the embodiments of the present disclosure will be described below with reference to the accompanying drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. The embodiments and features of the embodiments in the present disclosure may be arbitrarily combined with each other without conflict. The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

It is to be understood that the description of the embodiments of the present disclosure emphasizes the differences between the embodiments, and the same or similar parts may be referred to each other, so that the descriptions thereof are omitted for brevity.

For example, in a scenario where burst traffic causes congestion, referring to fig. 1, it is assumed that a port a and a port B of a certain network device are respectively an ingress port, a port C is an egress port, broadband rates of the three ports are all 10G, and traffic on the port B is high-priority traffic. When a port a and a port B send data packets to a port C at the same time at the rate of 10G in a certain time period, at this time, the port C loses packets because the received bandwidth exceeds the maximum bandwidth that the port itself can bear, and how to ensure that traffic on the port B is not lost and the time delay is determined in this scenario.

A plurality of queues are distributed on an outlet end of the equipment through QoS, the outlet queues are scheduled in absolute priority, and different queues are arranged through priority fields in messages, so that the high-priority messages are guaranteed to enter the outlet end first. However, the priority policy depends on the priority field of the packet, which easily causes packet loss of the packet stream due to unreasonable absolute priority scheduling for the high-priority packet stream, so that it is difficult to ensure that the time delay of the high-priority traffic is determined in an actual application scenario, and the method cannot be applied to an ethernet environment with a high real-time requirement on data transmission.

Therefore, the embodiment of the present disclosure provides a message forwarding method, which may be applied to a network chip, where the network chip may be an Application Specific Integrated Circuit (ASIC) chip or other chips, and may specifically be adjusted accordingly according to actual situations.

Referring to fig. 2, a method for forwarding a packet according to an embodiment of the present disclosure may include:

a first type of priority of a received message stream is dynamically determined 201.

Wherein the message flow is composed of at least one message with the same message characteristics.

The message characteristics may be determined from at least one field in the message header. For example, a plurality of messages having the same source IP address constitute a message flow.

The message characteristics may also be determined according to an ingress port of the network chip for receiving the message, for example, a message flow is formed by a plurality of messages received by the same ingress port.

The message flow may be an ethernet frame flow, or a message flow composed of other messages, for example, an IP message.

Here, the first type of priority of the message flow is used for representing the priority order of forwarding the message flow by the network chip.

It can be understood that different message flows may have different priorities, for example, for a message flow with a higher importance level, the corresponding priority is higher, and if the importance level is lower, the corresponding priority of the message flow is lower.

In particular, the first type of priority of the received message stream may be dynamically determined, where the first type of priority of the message stream is temporarily determined by the network chip after receiving the message stream, rather than being predetermined before the message stream is sent to the network chip.

The first type of priority of the dynamically determined message flow may be different from the second type of priority indicated by the priority field carried by the message flow itself.

202, when the first type priority of the message flow is the first priority, mapping the message flow to the first outlet channel.

Here, the first type of priority of the packet flow may be divided into a first priority and a second priority, and the first priority is higher than the second priority.

Accordingly, the egress port of the network chip may be divided into a first egress channel and a second egress channel.

The first outlet channel corresponds to the first priority and is used for transmitting the message flow with the first priority.

The second outlet channel corresponds to the second priority and is used for transmitting the message flow with the second priority.

In practical applications, the first priority packet stream may be marked as an EMAC (Express Media Access Control) packet stream, and the second priority packet stream may be marked as a PMAC (preemptible Media Access Control) packet stream.

Specifically, when the first type priority of the packet flow is the first priority, the packet flow is associated with the identifier of the first egress channel, and the packet flow is transmitted to the first egress channel.

And 203, when the first type priority of the message flow is the second priority, mapping the message flow to a second outlet channel.

Specifically, when the first type priority of the message flow is the second priority, the identifier of the second egress channel is associated with the message flow, and the message flow is transmitted to the second egress channel.

204, when the first egress channel is mapped with the packet stream, forwarding the packet stream mapped with the first egress channel from the egress port preferentially over the packet stream mapped with the second egress channel.

Specifically, when a message flow is mapped to the first egress channel, the message flow mapped to the first egress channel is transmitted to the first egress channel, and is preferentially forwarded from the egress port to the outside compared with the message flow mapped to the second egress channel.

In practical applications, when a first egress channel is mapped with a packet stream, the second egress channel may be closed or disabled to stop transmission of the packet stream mapped with the second egress channel, and forward the packet stream mapped with the first egress channel to the outside from the egress port preferentially through the first egress channel.

And after the first outlet channel finishes the transmission of the message flow, starting the transmission of the message flow mapped with the second outlet channel.

In the message forwarding method, the first type priority of the received message flow is dynamically determined, and when the first type priority of the message flow is the first priority, the message flow is mapped to a first outlet channel; when the first type priority of the message flow is the second priority, the message flow is mapped to a second outlet channel; when the first egress channel is mapped with a packet stream, the packet stream mapped with the first egress channel is forwarded from the egress port preferentially over the packet stream mapped with the second egress channel.

Because the first class priority of the message flow is dynamically determined, the priority scheduling of the message flow between the outlet channels is not absolute priority scheduling but dynamic scheduling, so that the rationality of the priority scheduling of the message flow can be realized, and the situation of message packet loss caused by unreasonable scheduling priority is reduced to a certain extent.

Therefore, deterministic forwarding time delay can be provided for the high-priority message from a network chip forwarding pipeline, and the high-priority data stream can be guaranteed not to be influenced even in a congested scene, so that support is provided for an Ethernet environment with high real-time data transmission requirements.

In an embodiment, as shown in fig. 3, the dynamically determining the first type of priority of the received packet stream in step 201 may include:

301, obtaining preset information corresponding to the message flow according to the preset configuration information.

The preset configuration information is stored in the network chip, and the preset configuration information includes different preset information set for different message flows.

Here, different message flows can be distinguished according to message characteristics. The message characteristics may be determined from fields other than the priority field carried by the message stream.

For example, the message characteristics may be one or more of a source IP address, a source port, a destination IP address, a destination port, and a transport layer protocol.

And 302, mapping the preset information in a priority mapping table to obtain the first type of priority of the message flow.

Specifically, after the preset information corresponding to the packet flow is obtained, the priority mapping table may be queried according to the preset information, and the first type priority of the packet flow is determined according to the priority mapping result.

The priority mapping table is preset with a mapping relation between preset information and the first type of priority. The mapping relationship between the preset information and the first-type priority may be a many-to-one relationship.

In the embodiment of the present disclosure, preset information corresponding to a message stream is obtained through preset configuration information, and priority mapping is performed on the preset information, so as to obtain a first type of priority of the message stream. In this way, it can be specified which packet has a higher priority based on the preset configuration information, so that the priority scheduling of the packet flow between the egress channels is not absolute priority scheduling, but dynamic scheduling. Therefore, the rationality of the priority scheduling of the message flow is realized, the situation of message packet loss caused by unreasonable scheduling priority is reduced to a certain extent, and the certainty of the time delay of a high-priority message is ensured.

In an embodiment, as shown in fig. 4, in the step 301, acquiring preset information corresponding to a packet stream according to preset configuration information may include:

401, the message characteristics of the message stream are extracted.

Specifically, the header of the packet flow is analyzed to obtain at least one field in the header, and the packet characteristic of the packet flow is determined according to the at least one field in the header.

Here, at least one field for determining the message characteristics of the message flow may be set according to the actual application requirement, and is not limited specifically here.

In one example, to make deterministic low-latency traffic forwarding unrestricted by the priority field content in the message, at least one field used to determine the message characteristics of the message flow may be different from the priority field in the message flow.

In one example, the message characteristics include: at least one of a source IP address, a source port, a destination IP address, a destination port, and a transport layer protocol.

And 402, matching preset information corresponding to the message characteristics from a pre-configured message matching rule list.

The message matching rule list comprises a plurality of pre-configured table items. And different table entries are used for matching different message characteristics to obtain corresponding preset information.

The message matching rule List may specifically be an Access Control List (ACL). The ACL comprises a plurality of ACL entries, and each ACL entry stores a value of a message characteristic and preset information corresponding to the value of the message characteristic.

Specifically, after the message features in the message stream are extracted, the value of the message feature may be used as a search key, a table entry corresponding to the value of the message feature is searched in a preconfigured message matching rule list, and preset information corresponding to the value of the message feature is matched from the table entry.

For example, taking a source IP address as a message feature, the message matching rule list may be searched according to a value of the source IP address, and when the value of the source IP address belongs to a source IP address range specified by a certain entry, preset information corresponding to the source IP address range in the entry may be determined as preset information corresponding to the value of the source IP address.

It can be understood that, corresponding preset information may also be matched from the message matching rule list by combining a plurality of message features, which is not specifically limited in this disclosure.

In one embodiment, before step 201 is performed, the method may further comprise:

and generating preset configuration information according to the configuration operation information of the preset information corresponding to the message flow.

Specifically, a configuration interface is provided for a user to receive configuration operation information, wherein the configuration interface includes message characteristics of a message flow and preset information options, and the configuration operation information includes a corresponding relationship established on the configuration interface for the message characteristics of the message flow and the preset information options.

In the embodiment of the present disclosure, the preset information corresponding to different message flows is set according to the message characteristics, so that the preset information corresponding to the message flow can be determined subsequently according to the source IP address, the source port, the destination IP address, the destination port, or the transport layer protocol of the message flow, and then the first class priority of the message flow is determined.

In addition, through the setting of the configuration interface, a user can configure the preset information corresponding to different message flows through the configuration interface, so that the configuration requirements of the user on the preset information corresponding to different message flows can be met.

In one embodiment, the preset information includes: transmission priority and/or drop priority.

The preset information corresponding to the packet flow may be a transmission priority.

In practical applications, the higher the transmission priority corresponding to a message flow, the easier the message flow is to be transmitted.

The preset information may be marked using marking information, which may be a text mark, for example, the transmission priority is "first level" indicating that the transmission priority is higher, and the transmission priority is "second level" indicating that the transmission priority is lower. Further, the label information may also be a numeric label or an alphabetical label, or the like.

The preset information corresponding to the packet flow may be a discarding priority. The discarding priority is used for indicating the discarding sequence of the messages when the network is congested.

In practical applications, the drop priority may be expressed using the color of the message. The color of the message has three values, and the discarding priority is Green, yellow and Red from low to high in sequence.

In an example, when the preset information includes a transmission priority and a drop priority, in the step 302, mapping the preset information in a priority mapping table to obtain a first type of priority of the packet flow may include:

and mapping the combination of the transmission priority and the discarding priority in a priority mapping table to obtain the first type of priority of the message flow.

In the embodiment of the present disclosure, the determination of the first class priority of the packet flow does not depend on single preset information, but is determined by mapping in the priority mapping table based on the combination of the transmission priority and the drop priority, so that the first class priority of the packet flow is determined by two kinds of preset information, the priority of the packet flow can be finely divided, and thus, a complex application scenario can be effectively dealt with.

In one embodiment, the method may further comprise:

determining a priority field carried by a message flow; wherein the priority field indicates a second type of priority.

Here, the first type of priority may be higher than the second type of priority.

In step 201, dynamically determining the first type of priority of the received packet stream may include:

and mapping the combination of the priority field and the preset information in a priority mapping table to obtain the first type of priority of the message flow.

Here, the priority field may include: a cos (Code of service) field or a dscp (Differentiated Services Code Point) field.

In the embodiment of the present disclosure, by combining the priority field in the message stream and the preset information corresponding to the message stream acquired according to the preset configuration information, the dynamic priority of the message stream is dynamically determined by combining multiple information, and the reasonability of priority scheduling of the message stream can be further ensured.

Next, referring to fig. 5, an ASIC chip is taken as an example to illustrate a message forwarding method provided in the embodiment of the present disclosure. And the single port of the ASIC chip can simultaneously output PMAC and EMAC, and the ASIC chip preferentially schedules the message flow redirected to the channel corresponding to the EMAC.

As shown in fig. 5, the specific flow of the packet forwarding method is as follows:

1, the message flow performs message matching in an Internet Protocol (IPE) of the ASIC chip through a preconfigured Access Control List (ACL) to obtain a corresponding preset priority and color.

And 2, carrying out flow mapping on the priority and the color matched by the ACL in a priority mapping table, and determining whether the message flow is high-priority flow.

The priority mapping table is preconfigured with first priorities mapped by different preset priority and color combinations.

And 3, when the message flow is determined to be the high-priority flow, redirecting the message flow to a channel corresponding to the EMAC.

And 4, when the message flow is determined not to be the high-priority flow, redirecting the message flow to a channel corresponding to the PMAC.

And 5, the ASIC chip preferentially schedules and redirects the message flow of the channel corresponding to the EMAC.

In the message forwarding method provided by the embodiment of the disclosure, with the aid of an ASIC chip, a single port can simultaneously output 2 MACs (PMAC and EMAC, respectively), and each of the 2 MACs has a corresponding egress channel (channel).

The ASIC chip may match priorities and coloring to the packet flows based on configured ACLs of the user, and may designate a combination of one or more priorities and colors as a high priority channel (i.e., a channel corresponding to the EMAC) according to the priority mapping table.

Therefore, which message goes through the channel with high priority and which message goes through the channel with low priority can be designated based on specific flow, deterministic forwarding delay is provided for the high-priority message from the chip forwarding pipeline, and EMAC data flow with high priority can be guaranteed not to be influenced even in a congestion scene, so that support is provided for an Ethernet environment with high real-time requirement of data transmission.
