The invention will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

Example 1

The embodiment provides a table entry issuing method which is applied to a control plane; fig. 1 is a flowchart (one) of an entry issuing method according to an embodiment of the present invention, as shown in fig. 1, where the entry issuing method in this embodiment includes:

s102, obtaining a corresponding relation between a first table item and one or more second service modules, wherein the second service modules are service modules needing to use the first table item;

s104, issuing a first table item to a first service module so that the first service module can perform logic processing according to the first table item; and calling callback functions of one or more second service modules according to the corresponding relation between the first table item and the one or more second service modules.

It should be further noted that, in the step S102, a correspondence between the first table entry and one or more second service modules is obtained, that is, the service module that explicitly needs to use the first table entry is determined, so that the service module is selected from the service modules associated with the first table entry and is used as the second service module, and further is used as the notification object in the process of issuing the table entry.

In step S102, the corresponding relationship between the first entry and one or more second service modules may be recorded, stored or queried in a database, a lookup table, or the like, which is not limited in the present invention.

It should be further noted that, in step S104, the callback function of the one or more second service modules is called, that is, the notification of the one or more second service modules by the control is implemented. In step S104, the first service module performs logic processing according to the first entry, which may specifically be a write operation of the first entry.

In step S104, according to the correspondence between the first table entry and the one or more second service modules, the operation of calling the callback function of the one or more second service modules may be performed while the first table entry is issued to the first service module, or may be performed after the first table entry is issued to the first service module, after the first service module performs logic processing according to the first table entry, the notification processing of the second service module is performed. The invention is not limited in this regard.

It should be further noted that, in the step S102, the operation of obtaining the correspondence between the first entry and the one or more second service modules may be performed before the step S104 is performed, or the step S102 may be performed again after the step S104 is performed or the correspondence between the first entry and the one or more second service modules is supplemented or updated.

By the method for issuing the table entries in the embodiment, the control plane can acquire the corresponding relation between the first table entry and one or more second service modules, wherein the second service modules are service modules which need to use the first table entry; therefore, the control plane can call callback functions of the one or more second service modules according to the corresponding relation between the first table item and the one or more second service modules in the process of issuing the first table item to the first service module so that the first service module carries out logic processing according to the first table item. Therefore, the method for issuing the table entry in the embodiment can solve the problem of low efficiency of issuing the table entry caused by unnecessary notification processing in the process of issuing the table entry in the related technology, thereby improving the efficiency of issuing the table entry and further realizing the effect of rapidly issuing the table entry.

Specifically, before the first table entry is issued, the second service module needing to use the first table entry is obtained in advance, so that the service module which is not started or does not need to use the table entry in the service modules associated with the first table entry is screened, and further, the service module needing to be notified is limited in the second service module in the notification process of the control plane. By avoiding unnecessary notification operation, the efficiency of the list item issuing process can be obviously improved.

In an optional embodiment, the obtaining the correspondence between the first entry and the one or more second service modules includes:

and establishing a lookup table, wherein the lookup table is configured to store the corresponding relation between the first table item and one or more second service modules.

In an optional embodiment, the obtaining the correspondence between the first entry and the one or more second service modules further includes:

a third service module needing to use the first table entry is used as a second service module, so that the corresponding relation between the first table entry and one or more second service modules in the lookup table is updated; the third service module is a service module configured by the control plane at any time.

It should be further noted that, in the above-mentioned alternative embodiment, the third service module is configured to instruct the control plane to perform the service configuration processing at any time as the service module to be configured, where the control plane may need to use a plurality of entries in the process of configuring the third service module, and when the third service module needs to use the first entry, the third service module may be marked as the second service module, so as to update the correspondence between the first entry and one or more second service modules in the lookup table, that is, increase the number and objects of the second service modules corresponding to the first entry.

In an alternative embodiment, the lookup table is configured to store index information of the first entry and identification information of one or more second service modules.

It should be further noted that, in the above lookup table, the corresponding relationship between the first table entry and the second service module may be indicated by storing the index information of the first table entry and the identification information of one or more second service modules. The index information of the first table entry may be an index field of the first table entry, such as an internet protocol (Internet Protocol, IP) field, (Virtual Private Network Routing and Forwarding, VRF) virtual private network routing and forwarding table field, and so on.

In an alternative embodiment, the lookup table is further configured to store status indication information of one or more second service modules, where the status indication information is used to indicate whether the one or more second service modules are turned on in the switch.

It should be further noted that in the above alternative embodiment, the status indication information may indicate whether the second service module is turned on in the switch, and the second service module that is not turned on may not be notified.

In an optional embodiment, the calling the callback function of the one or more second service modules according to the correspondence between the first entry and the one or more second service modules further includes:

Inquiring in a lookup table according to the index information of the first table item to determine the identification information of one or more second service modules corresponding to the first table item, and calling callback functions of the one or more second service modules according to the identification information.

It should be further noted that in the above alternative embodiment, that is, in the process of issuing the first table entry by the control plane, index information of the first table entry, such as an IP field, a VRF field, etc., is obtained, and identification information of the second service module corresponding to the first table entry is determined in the above lookup table by adopting a search or searching manner according to the index field, so that the control plane can call callback functions of one or more second service modules according to the identification information.

In an alternative embodiment, the lookup table is a hash table.

In an alternative embodiment, the callback function of the one or more second service modules is a callback function that the one or more second service modules perform static registration in the initialization stage.

In an optional embodiment, the calling the callback function of the one or more second service modules according to the correspondence between the first entry and the one or more second service modules includes:

Establishing a notification queue, and adding the corresponding relation between the first table item and one or more second service modules to the notification queue;

and calling callback functions of one or more second service modules through the notification queue according to the corresponding relation between the first table item and the one or more second service modules.

It should be further noted that in the above alternative embodiment, in the notification process of the second service module, the control plane is not caused to directly call the callback function of one or more second service modules according to the serial writing manner of the table entry, and a notification queue is pre-established. The notification queue is independent of the issuing of the table entries, specifically, the corresponding relation between the first table entry and one or more second service modules is added into the notification queue, namely, the second service module corresponding to the first table entry needing to be notified is determined in the notification queue, so that callback functions of one or more second service modules are further called through the notification queue, and notification operation can be realized while the control plane continues to issue the subsequent table entries.

Compared with the prior art in which serial writing of the table entries is adopted to cause that the control plane needs to notify all service modules one by one and then issue the subsequent table entries, in the above alternative embodiment, the control plane completes the issue of the first table entry based on the notification of the service modules implemented by the notification queue, and then issues the subsequent table entries, so that the issue time of the whole table entries is further shortened. According to the technical scheme described in the above optional embodiment, the notification mechanism is further improved on the basis that the corresponding relation between the first table entry and one or more second service modules is obtained in advance in the embodiment so as to notify the second service modules, so that the issuing efficiency of the table entry is further improved.

In an optional embodiment, after the foregoing issuing the first entry to the first service module for the first service module to perform logic processing according to the first entry, the method further includes:

in a preset first processing thread, a second table item is issued to a first service module; the method comprises the steps of,

and calling callback functions of one or more second business modules through the notification queue in the newly-built second processing thread.

It should be further noted that, the first processing thread and the second processing thread are different threads, that is, after the control plane completes the issuing of the first table entry, the issuing of the second table entry and the notification processing of the second service module are respectively performed in different threads, where the first processing thread is an original thread for the control plane to issue the table entry, and the second processing thread is a new thread for the notification queue; by adopting the technical scheme described in the above optional embodiment, in the case of further ensuring that the notification processing of the notification queue is independent of the entry issuing processing, the coupling between the notification operation in the notification queue and the rest of the services of the control plane is reduced, so as to avoid possible mutual influence. Fig. 2 is a schematic working diagram of different threads in the table entry issuing according to an embodiment of the present invention, and a process of performing the table entry issuing and notification processing of the notification queue in the different threads is shown in fig. 2.

In an optional embodiment, the adding the correspondence between the first entry and the one or more second service modules to the notification queue includes:

and adding the index information of the first table item and the identification information of one or more second service modules into a notification queue.

In an optional embodiment, the notification queue is further configured to combine, according to the index information of the first entry, identification information of one or more second service modules in the notification queue.

It should be further noted that, in the above optional embodiment, the merging process indicates the notification queue to merge different second service modules corresponding to the first table entry into one operation to perform notification, specifically, when different second service module corresponding identification information exists in different processing orders in the notification queue, the notification queue needs to notify the second service modules according to the identification information in the corresponding processing order according to a preset manner, and through the technical scheme described in the above optional embodiment, the identification information of the second service modules in the different processing orders can be merged to perform notification in one process in the same processing order, so as to further improve notification efficiency of the notification queue.

In an alternative embodiment, the notification queue is a circular (First Input First Output, FIFO) first-in-first-out queue.

In order to further explain the table entry issuing method in this embodiment, the table entry issuing method is described in detail below by way of a specific embodiment.

In this embodiment, an address resolution protocol (Address Resolution Protocol, ARP) entry is taken as an example, i.e., an ARP entry is taken as the first entry in the above embodiment. Fig. 3 is a schematic diagram of an operation of ARP entry issuing according to an embodiment of the present invention, and a process of ARP entry issuing in this embodiment is shown in fig. 3.

In the system initialization stage, each service module statically registers a callback function. The system creates a hash table, where the hash table is used to store a correspondence between an entry and a service module that needs to use the entry, that is, a correspondence between a first entry and a second service module that needs to use a first expression in the foregoing embodiment. Specifically, the hash table stores index fields of the table entry, such as an IP field and a VRF field, and a flag of a service module that needs to use the table entry. Meanwhile, the system also needs to establish a ring FIFO queue for notification.

In the running process of the system, after the control plane configures a corresponding service module, if the service needs to use a certain table item in the hash table, if the service needs to use an ARP module of an ARP table item, the corresponding relationship between the service module and the table item is added to the hash table, and specifically, the number and the objects of the service modules corresponding to the original table item may be updated, or a table item and a corresponding service module may be newly added.

When the control plane learns the ARP table entry, the control plane issues the ARP table entry to an ARP module, the ARP module writes the ARP table entry into a hardware table, and then queries in a hash table by utilizing the index field, and if the hash table is found that other service modules needing to use the ARP table entry exist, the index information of the ARP table entry and the identification information of the corresponding service module are added into an annular FIFO queue. After the ARP module completes writing of the ARP list item, the list item issuing processing of the next-hop ARP list item is exited.

The system establishes a processing thread of the annular FIFO queue, in the processing thread, firstly, merging the service modules corresponding to ARP table items in the annular FIFO queue, specifically traversing all the contents to be processed in the annular FIFO queue, inquiring whether the service modules corresponding to the same ARP table item exist in different operations, if so, merging the service modules corresponding to the same ARP table item in different operations according to a merging rule, and executing according to the latest operation record by adding, updating the operation record and the like; further, if the above-mentioned combined service modules are the same, only the operation of the service modules is combined; if the combined service modules are different, a joining order notification is also required.

After the merging processing is completed, processing the service modules needing to be notified in the annular FIFO queue, and particularly calling callback functions of the service modules needing to be notified in sequence.

From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment. Based on such understanding, the technical solution of the present invention may be embodied essentially or in a part contributing to the prior art in the form of a software product stored in a storage medium (e.g. ROM/RAM, magnetic disk, optical disk) comprising instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the method according to the embodiments of the present invention.

s204, a first table item is issued to a first service module, so that the first service module carries out logic processing according to the first table item; and invoking callback functions of one or more fourth business modules through the notification queue.

It should be further noted that in step S202, the fourth service module is all the service modules associated with the first table entry.

It should be further noted that, in the above step S204, during the notification process of the third service module, the control plane is not caused to directly call the callback function of one or more third service modules according to the serial writing manner of the table entry, but a notification queue is pre-established in step S202. The notification queue is independent of the issuing of the entries, specifically, the correspondence between the first entry and one or more third service modules is added to the notification queue established in step S202, that is, the third service module corresponding to the first entry to be notified is determined in the notification queue, so that the callback function of one or more third service modules is further invoked through the notification queue, that is, the control plane can continue issuing the subsequent entries while implementing the notification operation.

By the method for issuing the table entries in the embodiment, a notification queue can be pre-established, and the corresponding relation between the first table entry and one or more fourth service modules is added into the notification queue; wherein the one or more fourth service modules are service modules associated with the first table entry; furthermore, the control plane may issue a first table entry to the first service module, so that the first service module performs logic processing according to the first table entry; and invoking callback functions of one or more fourth business modules through the notification queue.

Specifically, compared with the prior art in which serial writing of the table entries is adopted to cause that the control plane needs to notify all service modules one by one and then issue the subsequent table entries, in the above alternative embodiment, after the control plane completes issuing the first table entry based on notification of the service modules implemented by the notification queue, the control plane can issue the subsequent table entries, so that the time for issuing the whole table entry is further shortened, and further, the issuing efficiency of the table entries is improved.

In an optional embodiment, the adding the correspondence between the first entry and the one or more fourth service modules to the notification queue includes:

And adding the index information of the first table item and the identification information of one or more fourth service modules into a notification queue.
