Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes a message processing method, a device, an electronic apparatus, and a storage medium according to the present invention with reference to fig. 1 to fig. 4.
Fig. 1 shows a flow chart of a message processing method provided by the present invention, referring to fig. 1, the method includes:
11. acquiring a statistical request of an outgoing direction ACL of a message sent by receiving equipment, wherein the statistical request comprises a VNI field, and the VNI field characterizes a unique identifier of the receiving equipment;
12. matching the VNI fields on the storage information of each structural body in the linked list, and taking the number of successful matching as the statistical number of the outgoing direction ACLs of the messages sent by the designated equipment; the structure body storage information in the linked list comprises: the method comprises the steps that an output direction ACL number of a matched VNI message issued by a sending device, an input direction ACL number of metadata generated by a chip of the sending device for the VNI message, the output direction ACL number of the metadata, the VNI to be matched with an ACL list item and a list tail mark are matched; the transmitting device is a device that transmits a message to the receiving device.
In this regard, an access control list (Access Control List, hereinafter referred to as ACL) is a function commonly used for a switch. The system can control various behaviors of the message and has important position on a message processing pipeline of the exchange chip.
The exchange chip has a plurality of components including an in-direction processing module, an out-direction processing module, an exchange module and the like, and ACLs are classified into different sub-ACL types according to different action modules, including an in-direction ACL, an out-direction ACL and the like. The incoming ACL and outgoing ACL resources are mutually different, and the fields that can be matched and the actions that can be issued and the number of ACLs that can be issued are different.
Chip build ACLs of computer devices (e.g., routing devices) support matching many fields in both the ingress and egress directions, but the matching capabilities of these fields are supported differently in the ingress and egress directions ACLs. The support capability is also different for chips of different devices, for ACLs in the same direction. For example, for some chips, the ingress ACL and the egress ACL may both match the VNI (network identifier) field of the message, and for other chips, the ingress ACL may match the VNI field of the message, but the egress ACL may not match the VNI field of the message. If the user wants to count the message of the designated VNI sent out from a certain port, the user will send an outgoing direction ACL matching message VNI and count, and because some chips do not support the outgoing direction ACL matching the VNI field, the chips will return an error, and the error message is prompted to be unsupported, so that the function that the user wants to realize cannot be realized.
In this regard, the present invention provides a method for processing a message, in order to save the operation cost of a user, so that the user cannot feel the difference between chips, when an outgoing direction module on a chip that does not support an outgoing direction ACL configures an outgoing direction ACL to match a VNI of the message, two ACLs are issued, the first ACL is an incoming direction ACL for matching the VNI of the message, metadata (five-tuple) is generated, the metadata will accompany the message to reach the outgoing direction module, and at this time, a second ACL will hit, the second ACL is an outgoing direction ACL, matches the metadata corresponding to the message, and then the user performs the action desired by the user, such as counting.
In the present invention, for a computer device (the above-mentioned transmitting device), in the process of transmitting a message, the transmitting device performs a complete process of transmitting the message, and the hierarchical structure may be divided into a bottom chip (communication logic portion), a middle layer (business logic portion), and an upper layer (presentation operation portion). In order to achieve the above-mentioned implementation effect, the middle layer needs to create a data structure for the output direction ACL (here, the output direction ACL may be used as a user_entry due to user configuration) of the upper layer matching packet VNI, and record the correspondence between the user_entry and the two ACLs actually issued by the chip (here, the input direction ACL may be used as an ingress_chip_entry due to bottom layer chip configuration), and the output direction ACL may be used as an egress_chip_entry). To cope with a simultaneous configuration of multiple user entries matching different VNIs by the upper layer, a linked list may be constructed to manage these ACLs.
And constructing corresponding structure body storage information according to a preset data structure aiming at each message in the linked list. The structure storage information includes the following information:
an outgoing direction ACL number (user_entry_id) issued by the user, namely an outgoing direction ACL number of the matched VNI message issued by the sending device;
the chip corresponding to the input direction ACL number (ingress_chip_entry_id) for generating metadata, that is, the input direction ACL number for generating metadata for the VNI message created by the bottom chip of the sending device;
an outgoing direction ACL number (egress_chip_entry_id) matching this metadata, i.e., an outgoing direction ACL number matching metadata;
VNIs to be matched by ACL entries;
and unifying the structure body storage information corresponding to the user_entry issued by all users, namely configuring the table tail identification of the last member storage information in the linked list, wherein the storage information represents the last member storage information in the linked list, and the traversing operation in the linked list is convenient. It should be further noted that the table tail identifier is represented by a next_user_entry field, that is, a next_user_entry field is configured in each structure body storage information, and when the next_user_entry field is set to 0, the table tail information that characterizes the corresponding structure body storage information as a linked list is represented. If the next_user_entry field is set to 1, the corresponding structure body storage information is represented by non-table tail information.
In the invention, when the output direction statistics of the VNI message of a certain designated device (namely a designated receiving device) is queried, a statistical request of the output direction ACL of the message sent by the receiving device is obtained, wherein the statistical request comprises a VNI field, and the VNI field represents the unique identification of the receiving device.
Traversing the VNI fields in the statistic request in a linked list, matching the VNI fields on the storage information of each structural body in the linked list, if the VNI fields are the same, the corresponding ingress chip entry in the storage information of the structural body is matched with the VNI to be queried by the upper layer, and generating corresponding metadata after the VNI fields are matched with the VNI to be queried by the upper layer, wherein the count statistics of the designated VNI messages to be queried by the upper layer is the hit number of egress chip entry of the matched metadata in the structural body. Directly calling the chip interface to inquire the hit times of the chip entry in the outgoing direction and returning to the upper layer. I.e. the number of successful matches is used as the statistical number of the outgoing direction ACLs of the messages sent by the designated equipment.
According to the message processing method provided by the invention, the input direction ACL issued by the chip is matched with the message VNI and metadata is added to the message, the output direction ACL is matched with the message execution action of the designated metadata to construct a linked list, the VNI fields to be queried are matched with the VNI fields on the storage information of each structure in the linked list, and the number of successful matching is used as the statistic number of the output direction ACL of the message sent by the designated equipment, so that the aim of matching the output direction ACL with the VNI fields is achieved when some chips do not support the output direction ACL, and the purpose of message statistics can be achieved.
In a further method of the above method, when deleting a VNI message of a specific device (i.e., a specific receiving device), the outgoing ACL number that the sending device plans to delete is acquired at this time.
Traversing the linked list, determining structural body storage information to be deleted in the linked list based on the exit direction ACL number to be deleted, deleting the ACL corresponding to the structural body storage information to be deleted, and deleting the structural body storage information to be deleted in the linked list.
If the structural body storage information to be deleted has the table tail identification, the table tail identification is added to the structural body storage information on the structural body storage information to be deleted based on the serial number of each structural body storage information in the linked list.
In this regard, in the present invention, when the transmission of a message to a certain device is stopped, the ACL that controls the transmission of the message is deleted. At this time, since there is structure storage information for the message transmission in the linked list, in order to avoid an error of the subsequent count, it is necessary to delete the corresponding structure storage information in the linked list and delete the corresponding ACL in the database. During the deletion process, it is also necessary to traverse the linked list. The user_entry_id of each structure body storage information is then compared with the user_entry number to be deleted by the upper layer, and if so, the structure body storage information is deleted in the linked list. If the structure body storage information with the table tail identification is deleted, the table tail identification is configured on other structure body storage information in the linked list at the moment so as to show the integrity of the linked list information and continue to serve the subsequent traversal. Because all members in the linked list are arranged by number, the arrangement is equivalent to the arrangement by number. For this purpose, the next_user_entry field of the structure body storage information of the last piece of structure body storage information to be deleted is set to 0. When each piece of structure body storage information is used as a node, the next_user_entry field is set to 0, which means that the structure body storage information plays a role of a tail node in a linked list, so that a node of a layer above the deleted tail node is used as a new tail node.
According to the method, the corresponding structure body storage information can be deleted rapidly and accurately by traversing the linked list, so that effective management of the information is facilitated.
In a further method of the above method, it should be noted that deletion of the structure stored information in the linked list is performed by:
acquiring an input direction ACL number of metadata generated for the VNI message and an output direction ACL number of matching metadata from structure storage information to be deleted based on the output direction ACL number to be deleted;
based on the input direction ACL number of metadata generated for VNI message and the output direction ACL number of matching metadata, the input direction ACL corresponding to the input direction ACL number of generating metadata is deleted, and the output direction ACL of matching metadata is deleted in the database.
In the present invention, the computer device has the condition of recovering the message sent to a certain receiving device, so in order to avoid the complicated processing procedure and construction failure caused by reconstructing the corresponding structure body storage information in the linked list, the deleted ACL can be temporarily stored in the cache, and the structure body storage information to be deleted can be stored in the auxiliary linked list as the structure body storage information to be recovered. Here, both the cache and the auxiliary linked list serve as carriers for temporarily storing information to be deleted.
In the invention, a recovery time length is configured for each piece of deleted information, if the signal to be recovered is not received in the recovery time length, the information is not needed, and the information is completely deleted from the cache and the auxiliary linked list. And when the deleting time is smaller than the preset restoring time, restoring the deleted ACL to the database, and restoring the structural body storage information to the original position of the linked list based on the structural body storage information to be restored in the auxiliary linked list.
In the further method, the deleted information is controlled, so that the information can be recovered in the effective time, the reutilization of the information is improved, and the repeated construction is avoided.
In a further method of the above method, the following explanation is given to the processing steps of constructing the linked list, specifically as follows:
and acquiring an ACL issued by the newly added transmitting equipment, firstly judging whether the ACL is in an output direction, and when the ACL is in the output direction and the ACL is matched with the message VNI, constructing corresponding structure body storage information for the ACL in the output direction, and storing the structure body storage information in a linked list.
In the present invention, the linked list is necessarily constructed. The aim is to deal with the fact that the upper layer is simultaneously provided with a plurality of user entries matched with different VNIs, so that a linked list can be constructed to manage the ACLs.
When it is determined that the newly added ACL is the first ACL, the characterization has not yet constructed a linked list, i.e., there is no table structure of the linked list. The first time of construction is needed, then the structure body storage information corresponding to the newly added ACL is used as the header information of the linked list, that is, the structure body storage information corresponding to the newly added ACL is the header node of the linked list. And in a certain time, only one structural body storage information still exists in the linked list, and in order to ensure the integrity of the linked list, a table tail mark is added in the structural body storage information at the moment.
Accordingly, when it is determined that the newly added ACL is not the first ACL, it is indicated that it is after generation of other structure storing information, to this end, the structure storing information corresponding to the newly added ACL is placed at the end of the existing linked list as the end information of the linked list, while the end identifier is added in the structure storing information corresponding to the newly added ACL.
Further explaining, in the process of constructing the structure body storage information, recording the VNI, creating an incoming direction ACL of metadata generated by the chip of the sending equipment aiming at the VNI message, and recording the incoming direction ACL number of the metadata generated into the structure body storage information;
the chip of the transmitting device creates an outgoing direction ACL matching metadata, and records the outgoing direction ACL number matching metadata into the structure body storage information.
In the further method, the corresponding relation between the user_entry and the two ACLs actually issued by the chips is recorded through the linked list, so that the direction ACL matching VNI field is not supported by some chips, the query information can be carried out based on the traversal linked list, and the message statistics is realized.
FIG. 2 is a flow chart of constructing and deleting structure storage information for a traverse linked list. The contents of the above-mentioned submitted processes can be intuitively understood with reference to fig. 2, and detailed descriptions of the drawings are not repeated here.
