Description
Technical Field
The present invention relates to the field of network technologies, and in particular, to a packet forwarding control method, a packet transmission network, an electronic device, and a storage medium.
Background
Network service providers often deploy various transmission lines in a transmission network in order to guarantee quality of service and meet different line requirements of customers in terms of cost, quality, etc.
Common transmission networks include cdn (content Delivery Network), SD-WAN (Software Defined Wide Area Network), and the like, where the SD-WAN is a service formed by applying SDN (Software Defined Network) technology to a Wide Area Network scenario, and the service may be used to connect enterprise networks, data centers, internet applications, and cloud services in a Wide geographic range.
The final purpose of SD-WAN is to use various internet lines to replace expensive private lines such as MPLS (Multi-Protocol Label Switching) lines and physical lines such as SDH (Synchronous Digital Hierarchy) lines, but many enterprises do not completely abandon lines with guaranteed quality of service, but rather tend to deploy hybrid networks, that is, to migrate some relatively unimportant traffic to internet lines on the basis of keeping the original private lines or physical lines transmitting critical service data. Therefore, multiple lines such as a private line, a physical line, and an Internet line may be included between service nodes of the SD-WAN network architecture, for example, between a CPE (Customer Premise Equipment) and a POP (Point of Presence), between a POP and a POP, and in other words, one service node may access multiple lines such as a private line, a physical line, and an Internet line, and currently, when a service node forwards a packet, the service node selects a corresponding transmission line to forward the packet according to a routing policy set by a source IP (Internet Protocol) address or a destination IP address of the packet, and this packet forwarding control manner has at least the following two problems:
firstly, all messages with the same source address or destination address are forwarded through the same transmission line, however, the messages corresponding to the same source address and destination address are not all important service messages, once the non-important service messages occupy expensive lines such as private lines or physical lines, additional cost is generated, and the transmission safety of the important service messages cannot be ensured;
second, in the prior art, the line selected by the central controller or the service node itself according to the source IP or the destination IP is generally a complete transmission line, that is, the line includes a start point, an end point, and all transit nodes passed through.

Detailed Description
In order to solve the problems in the background art, embodiments of the present invention provide a message forwarding control method, a message transmission network, an electronic device, and a storage medium.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
The message forwarding control method provided by the embodiment of the invention is applied to various types of transmission networks, and the embodiment of the invention will be described in detail below by taking an SD-WAN service network as an example.
Referring to fig. 1, which is an application scenario diagram of a packet forwarding control method according to an embodiment of the present invention, a transmission network applied by the packet forwarding control method may be: in an application scenario, the CPE may be configured to communicate with a source end device and/or a destination end device deployed in a client intranet, so as to enable the source end device or the destination end device of the intranet to access a service network constructed by the POP.
The source end and the destination end are used to identify a data sending end and a data receiving end in a data transceiving process, and are generally devices of a client side, such as user equipment, an application server, a data center, and the like.
The access nodes CPE and the transit nodes POP may be deployed in network transit devices, such as switch devices, router devices, servers, and the like.
In an application scenario as shown in fig. 1, a CPE simultaneously accesses a physical dedicated line and an internet line, for example, the CPE and a target server are connected by a physical dedicated line, the CPE and POP1 are connected by an internet line, when the CPE receives a packet sent to the target server (target device) from a source device (not shown in fig. 1), an appropriate line can be selected for the packet to transmit based on the method provided in the embodiment of the present invention, and it is noted that the method provided in the embodiment of the present invention is applicable to any service node in a transmission network that accesses at least two lines, in other words, when forwarding the packet from the CPE, POP2, and POP3, the illustrated POP1 can select an appropriate line to transmit the packet based on the method provided in this embodiment, so that, the autonomous line selection can be performed based on each service node, the flexible adjustment of the transmission line is realized, and the transmission stability is ensured.
Based on the above application scenarios, exemplary embodiments of the present invention will be described in more detail below with reference to fig. 2 to 3, it is understood that the above application scenarios are only shown for the convenience of understanding the spirit and principle of the present invention, and the embodiments of the present invention are not limited in any way herein. Rather, embodiments of the present invention may be applied to any scenario where applicable.
As shown in fig. 2, which is a schematic diagram of an implementation flow of a message forwarding control method provided in an embodiment of the present invention, the message forwarding control method can be applied to any service node (such as CPE, POP1, POP2, and POP3 in fig. 1) accessing at least two transmission lines in a transmission network, and the message forwarding control method includes the following steps:
s11, extracting the message characteristic information of the message to be forwarded, and identifying the service application type of the message to be forwarded according to the message characteristic information.
In specific implementation, a service node (CEP or POP) in the SD-WAN network system receives a message to be forwarded, extracts message characteristic information of the message to be forwarded, and identifies a service application type to which the message to be forwarded belongs according to the extracted message characteristic information.
Specifically, a system kernel in the service node sends a received message to be forwarded to an application layer agent program, the application layer agent program extracts message characteristic information of the message to be forwarded, and identifies a service application type to which the message to be forwarded belongs according to the message characteristic information.
In a preferred implementation, a service node system kernel (such as a Linux kernel) can send a received message to be forwarded to an application layer agent program through an ip _ tables instruction, and the application layer agent program extracts message characteristic information of the message to be forwarded and identifies a service application type to which the message to be forwarded belongs; in another implementation, the system core of the service node may also directly extract the message feature information of the message to be forwarded, and identify the service application type to which the message to be forwarded belongs, which is not limited in the embodiment of the present invention.
In a specific implementation process, the application layer agent program extracts message characteristic information of a message to be forwarded, and identifies a service application type to which the message to be forwarded belongs, which can be implemented based on a DPI (Deep Packet Inspection) technology, so as to set an identification rule according to an actual requirement.
For example, a technician may preset a message identification rule and a feature extraction rule in a service node according to a service requirement of a client to set a mapping relationship between message feature information and a service application type, and an application layer agent may extract the feature information of the message based on the feature extraction rule and identify a service application type to which the application layer agent belongs according to the preset identification rule, where the service application may be different intranet applications, such as an ERP (Enterprise Resource Planning) application, an OA (Office Automation) application, a mail application, a financial management application, and the like, and may also be a video application, a voice application, and the like. Taking an identification rule corresponding to the HTTP protocol and used for identifying a certain video application as an example, if information carried in fields such as a "host" field, a "uri" field, an "origin" field, and the like in a message can be successfully matched with the preset rule for identifying the video application, if the "host" field carries a website or a keyword of the video application, it indicates that the matching is successful, and it is determined that the service application type to which the message feature belongs is the video application. It can be understood that the setting of the service application type can be used for selecting a line for the message subsequently, and therefore, the service application type can be set according to actual requirements, and the present invention is not limited thereto.
And S12, adding a corresponding label to the message to be forwarded according to the corresponding relation between the preset service application type and the label.
In specific implementation, the service node may be configured with a tag corresponding to each service application type in advance, and establish a correspondence between the service application type and the tag, for example, the tag corresponding to the ERP application is set to be a, the tag corresponding to the OA application is set to be b, the tag corresponding to the video conference application is set to be c, and the like. After the application layer agent program in the service node determines the service application type to which the message to be forwarded belongs, the application layer agent program may add a corresponding tag to the message to be forwarded according to a preset correspondence between the service application type and the tag, that is: and adding a label corresponding to the service application type of the message to be forwarded, and sending the message to be forwarded carrying the label to a system kernel.
Specifically, the corresponding label may be added to the packet to be forwarded in the following manner:
the first method is as follows: and determining a socket (socket) corresponding to the message to be forwarded, and setting a label in the socket.
The method is characterized in that a mode of setting a label corresponding to a message to be forwarded in a socket corresponding to the message to be forwarded is adopted, the message to be forwarded does not bring any influence on the message to be forwarded, and the label can automatically fail along with the closing of a socket, so that the label on the socket can act on all messages based on the socket communication.
The second method comprises the following steps: and adding the label into the IP characteristic value of the message to be forwarded.
By adding the label corresponding to the message to be forwarded to the IP characteristic value of the message to be forwarded, if the label is set at the flag bit of the IP message, the line selection of a single message to be forwarded can be realized, that is: the service node can select a corresponding transmission line for each message to be forwarded, so that the line selection is more flexible.
It should be noted that steps S11 and S12 may be implemented in the application layer proxy, and step S13 is implemented in the system kernel of the service node. Steps S11 to S13 may also be implemented in the system kernel of the service node, which is not limited in this embodiment of the present invention.
And S13, forwarding the message to be forwarded according to the route specified in the routing rule corresponding to the label, wherein the route specified by the routing rule is determined based on the service application type corresponding to the label.
In specific implementation, the service node sets a corresponding routing rule in advance based on each label, a transmission line corresponding to the label is designated in the routing rule, a routing rule table is generated, the line designated in the routing rule is determined based on a service application type corresponding to the label, the service application type and the label have a preset corresponding relationship, namely the service application type, the label and the routing rule are in one-to-one correspondence, the routing rule can include a transmission line identifier, and the transmission line corresponding to the corresponding label is uniquely represented by the transmission line identifier.
Specifically, the service node searches a routing rule corresponding to the label added to the packet to be forwarded from the preset routing rule table according to the correspondence between the preset label and the routing rule, and forwards the packet to be forwarded to the next node through the transmission line corresponding to the transmission line identifier specified in the routing rule.
Taking the application scenario of fig. 1 as an example, assuming that a label corresponding to ERP application is a, a label corresponding to OA application is B, the preset label a corresponds to a routing rule 1, and a label B corresponds to a routing rule 2, where a transmission line identifier in the routing rule 1 is a (representing a physical dedicated line), a transmission line identifier in the routing rule 2 is B (representing an internet line), if the label added to the message to be forwarded is a, the message to be forwarded is forwarded using the physical dedicated line corresponding to the transmission line identifier in the routing rule 1 as a, and if the label added to the message to be forwarded is B, the message to be forwarded is forwarded using the internet line corresponding to the transmission line identifier in the routing rule 2 as B.
It should be noted that, in the embodiment of the present invention, a corresponding forwarding exit is set in a routing rule configured on a service node, that is, the service node accesses different transmission lines through different forwarding exits, and only the forwarding exits corresponding to labels in the routing rule are defined, so that the routing rule is only used for controlling which forwarding exit the packet is sent from, and does not control the whole process of packet transmission, in other words, the current service node sends the packet to be forwarded out, a transmission line through which the packet to be forwarded reaches a next service node is selected by the current service node, if the next service node also has at least two lines, then the next node may also select a transmission line for the packet based on the method of the present embodiment, it can be understood that, in the embodiment of the present invention, because the routing rule on each service node is configured separately, then packets belonging to the same service application type may configure different routing rules on different nodes, the method and the device dynamically adapt to the change of each section of transmission line, thereby ensuring the stability of transmission, and being more flexible compared with the mode of selecting the line by an initial node in the prior art.
Before forwarding the message to be forwarded according to the found routing rule, the method further comprises the following steps: and deleting the label added to the message to be forwarded so as to avoid the influence of the label added to the message on the subsequent service node.
Based on the method, the user can preset different transmission lines of the service messages of different service application types according to requirements, for example, important service messages can be set to be forwarded through a private line or a physical private line, and common service messages are set to be forwarded through an internet line, so that the problem that the non-important service messages occupy expensive private lines to generate extra cost is solved, and the transmission safety of the important service messages is improved.
Further, in order to improve transmission stability, in the embodiment of the present invention, the service node may further monitor each line included in the service node, obtain state information of each line according to a preset time period, and update, for any line, the first routing rule corresponding to the line when it is determined that the line satisfies the set condition according to the state information of the line.
In a specific implementation process, when the state of the line is determined not to meet the requirement of the service application type in the first routing rule, a suitable line is selected for the service application type in the first routing rule again, and the first routing rule is updated based on the newly selected line.
Specifically, requirements for business application types may include, but are not limited to including: whether the line is abnormal or not, whether the line is congested or not, whether the line quality is changed or not, and the like. When the state of the line is an abnormal state or a congestion state, or the quality of the line is poor, determining that the state of the line does not meet the requirement of the service application type in the first routing rule, then, the service node selects the line which is most matched with the requirement of the service application type according to the states of all the lines, modifies the line identification in the first routing rule into the most matched line identification, obtains the updated first routing rule, issues the updated first routing rule, and then forwards the message to be forwarded according to the updated first routing rule.
In implementation, whether the line is abnormal or not can be judged through time delay, and whether the line is congested or not can be judged through used bandwidth and residual bandwidth of the line.
Specifically, the service node may send a probe signal to a next service node corresponding to the packet to be forwarded through each line according to a preset time period, record a time delay for each next service node to return a response message through each line, determine that the corresponding line is abnormal if the time delay exceeds a preset time threshold, and determine that the corresponding line is normal if the time delay is less than or equal to the preset time threshold, where the preset time threshold may be set according to an empirical value.
The service node may allocate an available bandwidth to each line according to its physical bandwidth, and in implementation, the service node acquires the used bandwidth of each line according to a preset time period, and may acquire a remaining bandwidth available to each line according to the available bandwidth of each line, and if the remaining bandwidth is less than a preset bandwidth threshold, it determines that the state of the line is a congestion state, and if the remaining bandwidth is greater than or equal to the preset bandwidth threshold, it determines that the state of the line is a non-congestion state, where the preset bandwidth threshold may be set according to actual needs, which is not limited in the embodiments of the present invention.
The preset time period may be set according to the requirement, which is not limited in the embodiments of the present invention.
Further, when the state of the monitored line meets the requirement of the service application type in the first routing rule before updating, if the state of the monitored line returns to normal or is no longer congested, the service node returns the line identifier in the updated first routing rule to the line identifier in the first routing rule before updating.
For example, in fig. 1, when POP1 monitors that physical dedicated line a between POP2 and POP1 is abnormal (or jammed, or has line quality degraded), it may modify line identifier a in routing rule 1 corresponding to label a in POP1 into line identifier B and issue it, or directly delete routing rule 1 corresponding to label a, reset routing rule 1 corresponding to label a, set routing rule 1 as line identifier B of transmission line corresponding to label a and issue it, thus modify the transmission line in routing rule 1 into internet line, further POP1 sends the message to be forwarded to POP2 through internet line between POP2, and when POP1 monitors that physical dedicated line a between POP2 and POP is restored to normal or not jammed, restore modified routing rule 1 to routing rule 1 before update, that is: and modifying the line identification B of the transmission line corresponding to the label a into A.
The message forwarding control method provided by the embodiment of the invention can be directly implemented on a single service node, can realize the guidance of data message flow by the single service node, and can directly reconfigure the local routing rule of the service node when the transmission line needs to be adjusted, without setting the whole routing rule table, so that the flexibility and the efficiency of configuration are higher.
Based on the same inventive concept, the embodiment of the invention also provides a message transmission network, wherein the transmission network comprises a plurality of service nodes, and when the service nodes receive the message to be forwarded, if the message to be forwarded is determined to correspond to at least two forwarding lines, the message to be forwarded is forwarded based on the message forwarding control method.
