[0002] Multicasting is a network technology that allows one or more hosts (i.e., multicast sources) to send a single multicast packet to multiple hosts. It can be understood that multicast technology can save bandwidth resources and reduce network load, and thus has been widely applied in various fields such as video conferencing, online games, and IPTV.

[0012] If the user setting module determines that the message to be processed is not processed for the first time based on the current processing status, detect the first processing rule for performing a preset process on the message to be processed last time;

[0013] Traverse the second processing rules adjacent to the first processing rule in the multi-dimensional linked list, and select target node information for characterizing the second processing rule.

[0014] Optionally, in another embodiment based on the above method of the present application, after traversing the second processing rules adjacent to the first processing rule in the multi-dimensional linked list, further include:

[0015] If the second processing rule adjacent to the first processing rule is not found in the multi-dimensional linked list, return a reply message to the multicast module for informing that the message to be processed has been processed.

[0016] Optionally, in another embodiment based on the above method of the present application, performing a preset process on the message to be processed based on the processing rule characterized by the target node information includes:

[0017] The multicast module performs one of modification processing, unicast processing, replication processing, mirroring processing, multicast processing, and discarding processing on the message to be processed based on the processing rule characterized by the target node information.

[0018] Optionally, in another embodiment based on the above method of the present application, after performing a preset process on the message to be processed based on the processing rule characterized by the target node information, further include:

[0019] The multicast module determines whether the processing of the message to be processed is completed based on the processing result obtained by performing a preset process on the message to be processed;

[0020] If so, send the message to be processed to the message object;

[0021] If not, continue to send a request message to the user setting module for obtaining another node information in the multi-dimensional linked list.

[0022] Optionally, in another embodiment based on the above method of the present application, before the multicast module receives the message to be processed, further include:

[0023] The user setting module obtains an initial multi-dimensional linked list; and,

[0024] Obtain the configuration instruction of the user, and obtain the multi-dimensional linked list based on the configuration instruction and the initial multi-dimensional linked list;

[0025] Wherein, the configuration instruction is used to add corresponding preset rules to at least one node information in the initial multi-dimensional linked list.

[0026] Wherein, according to another aspect of the embodiments of the present application, a device for multicasting a message is provided, which is applied to a switch including a multicast module and a user setting module, and includes:

[0033] In this application, when the multicast module in the switch receives a message to be processed, it sends a request message for obtaining the information of a node in the multidimensional linked list to the user setting module. The request message includes the current processing status of the message to be processed. After receiving the request message, the user setting module selects the target node information that matches the current processing status from the preset multidimensional linked list and returns the target node information to the multicast module. After receiving the target node information, the multicast module performs preset processing on the message to be processed based on the processing rules represented by the target node information.

[0046] Now, various exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0052] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0053] The following in combination with Figures 1-6To describe a method for multicasting packets according to an exemplary embodiment of the present application. It should be noted that the following application scenarios are only shown for the convenience of understanding the spirit and principle of the present application, and the embodiments of the present application are not limited in this regard. On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0054] The present application also proposes a method, apparatus, electronic device, and medium for multicasting packets.

[0055] Figure 1 Schematically shows a flowchart of a method for multicasting packets according to an embodiment of the present application. As Figure 1 shown, this method is applied to a switch including a multicast module and a user setting module, and includes:

[0056] S101, when the multicast module receives a packet to be processed, it sends a request message for obtaining the information of a node in the multidimensional linked list to the user setting module, and the request message includes the current processing status of the packet to be processed.

[0057] S102, after receiving the request message, the user setting module selects the target node information that matches the current processing status from the preset multidimensional linked list, and returns the target node information to the multicast module.

[0058] S103, after receiving the target node information, the multicast module performs preset processing on the packet to be processed based on the processing rules represented by the target node information.

[0059] Among them, the multidimensional linked list proposed in the present application is a storage structure that is non - continuous and non - sequential on the physical storage structure in the switch, and the logical order of data elements is realized through the pointer link order in the linked list.

[0060] In one way, multiple node information can be stored in the multidimensional linked list. And each node information stores one or more processing rules. It can be understood that the processing rules are pre - configured by the user in the multidimensional linked list, such as copying, deleting, mapping, etc. for the packet to be processed. So that the multicast module can obtain in real - time the rules that the user wants to process a certain packet.

[0061] Specifically, as Figure 2 shown, when the packet to be processed enters the data communication network switch device and passes through the multicast module therein, the multicast module will parse the packet, and then combine the corresponding node information in the multidimensional linked list set by the user to implement the preset processing of the input packet.

[0062] In one way, during the multicast control process, this application uses a multi-dimensional linked list analysis method to specifically analyze each node of the multicast linked list, so as to determine the corresponding processing method for the message: unicast, replication, mirroring, multicast, discarding, etc., and then perform corresponding operations on the input message to meet the user's setting requirements, avoiding situations such as missed broadcasts and misbroadcasts.

[0063] Furthermore, this application combines Figure 3 to illustrate the specific steps of the solution:

[0064] Step 1: When the multicast module receives a message to be processed, it sends a request message to the user setting module to obtain the information of a node in the multi-dimensional linked list.

[0065] Among them, the request message includes the current processing status of the message to be processed.

[0066] Step 2: The user setting module receives the request message. Then, step 3 or step 4 is executed.

[0067] Step 3: If the user setting module determines that the message to be processed is being processed for the first time based on the current processing status, it selects the target node information representing the first processing rule from the multi-dimensional linked list.

[0068] In one way, the multicast module can access the user setting module through an initialization address passed in from the input end in the switch. Further, the user setting module processes the input address through various internal look-up table and other logical processes, and returns the processing result (i.e., the information of a certain node in the multi-dimensional linked list) to the multicast module.

[0069] Then, the multicast module parses the return result of the user setting module to determine the corresponding processing of the message to be processed, and outputs the processed message generated after processing. The embodiments of this application can implement the traversal processing of the message to be processed using the multi-dimensional linked list by repeatedly implementing the above steps, so as to complete the multicast processing of the message to be processed.

[0070] In one way, the structure of the multi-dimensional linked list proposed in this application is as Figure 4 shown. For example, if both the l2_ptr and l3_ptr of the current node in the multi-dimensional linked list are not null and there is no temporarily stored l3_ptr, then the current l3_ptr will be temporarily stored and the next access will be to l2_ptr.

[0071] In another way, if both l2_ptr and l3_ptr are not null and there is a temporarily stored l3_ptr, then the current l3_ptr will be ignored and the next access will be to l2_ptr.

[0072] In another way, if l2_ptr is not null and l3_ptr is null, then the next access is to l2_ptr

[0073] In another way, if l2_ptr is null and there is a cached l3_ptr, regardless of the state of the current node l3_ptr, clear the cached l3_ptr and use it as the next node for traversal

[0074] In another way, if l2_ptr is null, l3_ptr is not null and there is no cached l3_ptr, then the next access is to l3_ptr

[0075] In another way, if l2_ptr is null, l3_ptr is also null and there is no cached l3_ptr, then the traversal ends.

[0076] Step 4: When the user setting module determines, based on the current processing state, that the message to be processed is not processed for the first time, detect the first processing rule for the preset processing of the message to be processed last time.

[0077] Step 5: Traverse the second processing rule adjacent to the first processing rule in the multi-dimensional linked list, and select the target node information representing the second processing rule.

[0078] Step 6: If no second processing rule adjacent to the first processing rule is found in the multi-dimensional linked list, return a reply message to the multicast module to inform that the message to be processed has been processed.

[0079] In one way, as Figure 5 shown, message interaction is carried out between the multicast module and the user setting module proposed in this application, and the response message of the user setting module is parsed. According to the parsing result, at least one corresponding processing is performed on the message to be processed, such as: modifying the byte value of part of the message, and then performing processing such as copying, mirroring, multicasting, or discarding.

[0080] Step 7: The user setting module returns the target node information to the multicast module.

[0081] Step 8: The multicast module performs preset processing on the message to be processed based on the processing rule represented by the target node information.

[0082] Step 9: The multicast module determines whether the processing of the message to be processed is completed based on the processing result obtained by performing preset processing on the message to be processed.

[0083] Step 10: If so, send the message to be processed to the message object.

[0084] Step 11: If not, continue to send a request message to the user setting module to obtain information about another node in the multi-dimensional linked list.

[0085] In one way, the management method of packets in the switch using a multi-dimensional linked list in this application can parse and process the response message Response of the user setting module. According to the parsing result, corresponding processing is performed on the input ingress packet, such as unicast, replication, mirroring, multicast, discarding, etc., and it is cached locally for output.

[0086] In one way, as Figure 6 shown, the multicast module will determine whether to continue interacting with the user setting module according to the parsing result. If so, update the initial mcr_ptr address, and then send the message again until the parsing result of the response message returned by the user setting module indicates that the traversal is completed, then the traversal ends and the multicast processing process ends. In another way, it can also be determined by the user setting module that the packet has been processed when the second processing rule adjacent to the first processing rule is not found in the multi-dimensional linked list. And return a reply message to the multicast module to inform that the packet to be processed has been processed.

[0087] In this application, when the multicast module in the switch receives a packet to be processed, it sends a request message to the user setting module to obtain information about a node in the multi-dimensional linked list. The request message contains the current processing status of the packet to be processed; after receiving the request message, the user setting module selects target node information that matches the current processing status from the preset multi-dimensional linked list, and returns the target node information to the multicast module; after receiving the target node information, the multicast module performs preset processing on the packet to be processed based on the processing rule represented by the target node information.

[0088] By applying the technical solution of this application, when the switch receives a packet, it does not directly forward it, but first interacts with the user configuration module to obtain the node information configured by the user in the multi-dimensional linked list for corresponding processing of the packet. So as to perform processing on the packet based on the processing rule reflected by the node information subsequently. Thereby avoiding the problem in the related art that the switch only forwards the packet and cannot perform certain processing on it, which affects the user service processing process.

[0089] Optionally, in another embodiment based on the above method of this application, after receiving the request message, the user setting module selects target node information that matches the current processing status from the preset multi-dimensional linked list, including:

[0090] If the user setting module determines that the message to be processed is processed for the first time based on the current processing status, select target node information for characterizing the first processing rule from the multi-dimensional linked list; or,

[0091] If the user setting module determines that the message to be processed is not processed for the first time based on the current processing status, detect the first processing rule for the previous preset processing of the message to be processed;

[0092] Traverse the second processing rules adjacent to the first processing rule in the multi-dimensional linked list, and select target node information for characterizing the second processing rule.

[0093] Optionally, in another embodiment of the method based on the present application, after traversing the second processing rules adjacent to the first processing rule in the multi-dimensional linked list, it further includes:

[0094] If no second processing rule adjacent to the first processing rule is found in the multi-dimensional linked list, return a reply message to the multicast module for informing that the message to be processed has been processed.

[0095] Optionally, in another embodiment of the method based on the present application, the preset processing of the message to be processed based on the processing rule characterized by the target node information includes:

[0096] The multicast module performs one of modification processing, unicast processing, replication processing, mirroring processing, multicast processing, and discarding processing on the message to be processed based on the processing rule characterized by the target node information.

[0097] Optionally, in another embodiment of the method based on the present application, after the preset processing of the message to be processed based on the processing rule characterized by the target node information, it further includes:

[0098] The multicast module determines whether the processing of the message to be processed is completed based on the processing result obtained by the preset processing of the message to be processed;

[0099] If so, send the message to be processed to the message object;

[0100] If not, continue to send a request message to the user setting module for obtaining another node information in the multi-dimensional linked list.

[0101] Optionally, in another embodiment of the method based on the present application, before the multicast module receives the message to be processed, it further includes:

[0102] The user setting module obtains an initial multi-dimensional linked list; and,

[0103] Obtain the configuration instruction of the user, and obtain the multi-dimensional linked list based on the configuration instruction and the initial multi-dimensional linked list;

[0104] Wherein, the configuration instruction is used to add corresponding preset rules to at least one node information in the initial multi-dimensional linked list.

[0105] By applying the technical solution of the present application, when the switch receives a message, it can be realized that instead of directly forwarding it, it first interacts with the user configuration module to obtain the node information configured by the user in the multi-dimensional linked list for corresponding processing of the message. So as to process the message based on the processing rules reflected by the node information subsequently. Thereby avoiding the problem in the related art that the switch only forwards the message and cannot perform certain processing on it, which affects the user service processing process.

So as to process the message based on the processing rules reflected by the node information subsequently. Thereby avoiding the problem in the related art that the switch only forwards the message and cannot perform certain processing on it, which affects the user service processing process.

[0113] It traverses the second processing rules adjacent to the first processing rule in the multi-dimensional linked list, and selects target node information for characterizing the second processing rule.

Claims

1. A method for multicasting a message, characterized in that, it is applied to a switch including a multicast module and a user setting module, and includes: After the multicast module receives the message to be processed, it sends a request message for obtaining the information of a node in the multidimensional linked list to the user setting module, and the request message includes the current processing status of the message to be processed; After receiving the request message, the user setting module selects target node information that matches the current processing status from the preset multidimensional linked list, and returns the target node information to the multicast module; After receiving the target node information, the multicast module performs a preset process on the message to be processed based on the processing rule represented by the target node information; Before the multicast module receives the message to be processed, it further includes: The user setting module obtains an initial multidimensional linked list; and, Obtains a configuration instruction of the user, and based on the configuration instruction and the initial multidimensional linked list, obtains the multidimensional linked list; Wherein, the configuration instruction is used to add corresponding preset rules to at least one node information in the initial multidimensional linked list.

2. The method according to claim 1, characterized in that, After receiving the request message, the user setting module selects target node information that matches the current processing status from the preset multidimensional linked list, including: If the user setting module determines that the message to be processed is processed for the first time based on the current processing status, it selects target node information for representing the first processing rule from the multidimensional linked list; or, If the user setting module determines that the message to be processed is not processed for the first time based on the current processing status, it detects the first processing rule for the last preset process on the message to be processed; Traverses the second processing rules adjacent to the first processing rule in the multidimensional linked list, and selects target node information for representing the second processing rule.

3. The method according to claim 2, characterized in that, After traversing the second processing rules adjacent to the first processing rule in the multidimensional linked list, it further includes: If no second processing rule adjacent to the first processing rule is found in the multidimensional linked list, it returns a reply message to the multicast module for informing that the message to be processed has been processed.

4. The method according to claim 1, characterized in that, Performing a preset process on the message to be processed based on the processing rule represented by the target node information includes: The multicast module performs one of modification processing, unicast processing, replication processing, mirroring processing, multicast processing, and discarding processing on the message to be processed based on the processing rule represented by the target node information.

5. The method according to claim 1 or 4, characterized in that, After performing a preset process on the message to be processed based on the processing rule represented by the target node information, it further includes: The multicast module determines whether the processing of the message to be processed is completed based on the processing result obtained by performing a preset process on the message to be processed; If so, send the message to be processed to the message object; If not, continue to send a request message for obtaining information of another node in the multi-dimensional linked list to the user setting module.

6. A device for multicasting messages, characterized in that, applied to a switch including a multicast module and a user setting module, and comprising: The multicast module is configured to send a request message for obtaining information of a node in the multi-dimensional linked list to the user setting module when receiving a message to be processed, where the request message includes the current processing status of the message to be processed; and after receiving the target node information, perform a preset process on the message to be processed based on the processing rule characterized by the target node information; The user setting module is configured to select target node information matching the current processing status from a preset multi-dimensional linked list when receiving the request message, and return the target node information to the multicast module; The device is further configured to: Before the multicast module receives a message to be processed, the user setting module obtains an initial multi-dimensional linked list; and, obtain a configuration instruction of the user, and obtain the multi-dimensional linked list based on the configuration instruction and the initial multi-dimensional linked list; wherein the configuration instruction is used to add corresponding preset rules to at least one node information in the initial multi-dimensional linked list.

7. A switch, characterized in that, comprising: a memory for storing executable instructions; and, a processor for executing the executable instructions to complete the operations of the method for multicasting messages according to any one of claims 1-5.

8. A computer-readable storage medium for storing computer-readable instructions, characterized in that, when the instructions are executed by a processor, the operations of the method for multicasting messages according to any one of claims 1-5 are executed.
