Example one
Fig. 1 is a flowchart of a method for forwarding a link aggregation packet in a digital communication chip according to an embodiment of the present invention, where this embodiment is applicable to efficiently implement a case of forwarding a packet of a multicast group including a link aggregation port based on a small amount of configuration information of the link aggregation port, the method may be implemented by a forwarding device of the link aggregation packet in the digital communication chip, the forwarding device of the link aggregation packet in the digital communication chip may be implemented in a hardware and/or software manner, and the forwarding device of the link aggregation packet in the digital communication chip may be configured in the digital communication chip with a data transmission function. As shown in fig. 1, the method includes:
s110, acquiring multicast group information matched with the target message, and identifying at least one alternative physical port matched with the multicast group information in the digital communication chip.
The digital communication chip can be used for data transmission between devices, and one digital communication chip can comprise a plurality of common physical ports, so that when messages are forwarded through the digital communication chip, the messages can be forwarded through the common physical ports, or a plurality of common physical ports can be combined into a link aggregation port with high bandwidth, and the messages are forwarded through the link aggregation port.
In the embodiment of the present invention, the alternative physical port may refer to a physical port capable of being used for forwarding a target packet, the alternative physical port may be a common physical port or a link aggregation port, and each physical port in the link aggregation port may be used as a link aggregation port member port.
The multicast group information matched with the messages with different local area network addresses may be different, and the alternative physical port information for forwarding the target message can be obtained through the multicast group information.
In a specific embodiment, the multicast group information may be represented in a bitmap form, in a bitmap representing the multicast group information, each bitmap position has a mapping relationship with each physical port in the digital communication chip, whether a physical port mapped to each bitmap position is an alternative physical port may be represented by a bit, if a bit in a bitmap position is 1, it may be determined that a physical port in the digital communication chip mapped to the bitmap position is an alternative physical port, and if a bit in a bitmap position is 0, it may be determined that a physical port in the digital communication chip mapped to the bitmap position is not an alternative physical port.
And S120, respectively identifying the alternative physical ports as common physical ports or member ports of the link aggregation ports according to the query result of the link aggregation port identification bits of the alternative physical ports.
Preferably, in order to save the storage space of the link aggregation port identification bit in the digital communication chip, a storage space of 1 bit may be allocated to each physical port in the digital communication chip as the link aggregation port identification bit, and the physical port may be determined to be a common physical port or a member port of the link aggregation port by the identification value of the link aggregation port identification bit of each physical port.
In a specific embodiment, 0 and 1 may be used as an identification value of the link aggregation port identification bit, if the identification value is 0, the physical port belongs to a common physical port, and if the identification value is 1, the physical port belongs to a link aggregation port member port, and the configuration method of the link aggregation port identification bit is not limited to the configuration method used for illustration in this embodiment, and only needs to ensure that a storage space of a small digital-to-analog chip is occupied.
In an actual digital communication chip, there is usually a large amount of multicast group information, and if a link aggregation port identification method in the prior art is used, that is, a multi-bit storage space is allocated to each piece of multicast group information to identify the allocation condition of a link aggregation port, where the storage space of each bit is used to indicate an Identifier (ID) of an aggregation port, for example, 8 link aggregation ports exist in the digital communication chip, it is necessary to use an extra 8-bit storage space to indicate whether a link aggregation port exists in any multicast group, and each bit represents an aggregation port. A large amount of memory space of the digital chip is occupied, which may result in a reduction in communication performance of the digital chip.
The invention creatively provides that each physical port of the digital communication chip is configured with a link aggregation port identification bit for identifying whether each physical port belongs to a link aggregation port member port, and because the number of the physical ports in the digital communication chip is limited and each link aggregation port identification bit can only occupy a storage space of 1 bit, the link aggregation port identification method provided by the embodiment of the invention can effectively save the storage space in the digital communication chip.
S130, forwarding the copied message of the target message through a common physical port or a target member port in a link aggregation port to which a member port of the link aggregation port belongs.
It should be noted that, because the multicast group information matched with the target packet may include a plurality of common physical ports or target member ports in the link aggregation port to which the member ports of the link aggregation port belong, the target packet needs to be replicated, and each common physical port or target member port in the link aggregation port to which the member port of the link aggregation port belongs may forward the replicated packet.
Preferably, if the packet is forwarded through the link aggregation port, only any one member port in the link aggregation port needs to be forwarded, and in order to ensure the flow balance of each member port in the link aggregation port as much as possible, a target member port can be randomly selected from each member port in the link aggregation port to forward the packet.
Therefore, if a certain candidate physical port is identified as a link aggregation port member port, all effective member ports in the link aggregation port to which the physical port belongs can be further acquired, and one member port is randomly selected from all effective member ports in the link aggregation port for forwarding the duplicate packet.
Specifically, for the candidate physical port identified as the member port belonging to the link aggregation port, the link aggregation port information of the candidate physical port may be obtained through the configuration information of the candidate physical port. After the information of the link aggregation port is obtained, the number of effective member ports in the link aggregation port, which can be used for forwarding a message, and all the alternative member ports in the link aggregation port can be obtained through the configuration information of the link aggregation port. Further, the number of the effective member ports can be determined according to the number of the effective member ports, and one member port is randomly selected from the effective member ports to forward the duplicate packet.
In a specific embodiment, if the multicast group information includes a plurality of link aggregation ports, and physical port 1, physical port 2, and physical port 3 belong to one of the link aggregation ports, and only bit of bitmap position where physical port 2 is located is 1, and bit of bitmap position where the other two ports are located is 0, it may be identified that physical port 2 is an alternative physical port. Further, since the physical port 2 belongs to the link aggregation port member port, the identification value of the link aggregation port identification bit of the physical port 2 is 1, and it can be determined that the physical port 2 belongs to the link aggregation port member port by identifying the identification value of the link aggregation port identification bit of the physical port 2. Further, it may be identified from the configuration information of the physical port 2 that the physical port 2 specifically belongs to a specific link aggregation port in the multicast group information. Further, it can be obtained through the configuration information of the link aggregation port that the link aggregation port includes three valid member ports, and all the candidate member ports matched with the link aggregation port are physical port 1, physical port 2, and physical port 3. Further, one of the physical port 1, the physical port 2, and the physical port 3 may be randomly selected to forward the duplicate packet.
The advantages of such an arrangement are: by adopting the selection mode of the message forwarding port in the message forwarding method provided by the embodiment of the invention, when the information of each link aggregation port in the digital communication chip is configured, only each physical port and each link aggregation port are configured, and only a small storage space in the digital communication chip is occupied, thereby solving the problem that the storage space is large because the information of each multicast group needs to be configured with the information of the link aggregation port in the prior art.
According to the technical scheme of the embodiment of the invention, each alternative physical port matched with the multicast group information is identified in the digital communication chip according to the multicast group information matched with the target message, and each alternative physical port belongs to a common physical port or a member port of a link aggregation port, so that the storage space occupied by the physical port information configured in the digital communication chip and the link aggregation port information can be reduced in a mode of forwarding the duplicate message through the target member port in the link aggregation port to which the common physical port or the member port of the link aggregation port belongs, the power consumption of the digital communication chip is reduced, and the performance of the digital communication chip in the process of forwarding the link aggregation message is improved.

When a target member port is required to be selected from the link aggregation port to forward a packet, since the number of the effective member ports is 3, only the target member port is selected from the physical port 1, the physical port 2 and the physical port 3.
The advantages of such an arrangement are: when the state of the member port in the link aggregation port is changed, the message forwarding work can be continued only by changing a few data structures, and the maintenance time of the digital communication chip is effectively saved.
In the previous example, if all the candidate member ports in a certain link aggregation port are the physical port 1, the physical port 2, the physical port 3, and the physical port 4 is switched from the valid member port to the invalid member port, at this time, in addition to the need to perform corresponding correction on the fourth data structure corresponding to the link aggregation port, it is also necessary to traverse through all the multicast groups to obtain the target multicast group using the link aggregation port, and correspondingly refresh the multicast group information related to the target multicast group, that is, if the bitmap position corresponding to the port 4 in the target multicast group information is 1, it is necessary to adjust the bitmap position to 0, and select any one of the port 1, the port 2, and the port 3, and adjust the bitmap position of the selected port to 1.
In a specific embodiment, a 1-bit storage space may be allocated to each physical port in the digital communication chip, and is used for storing a link aggregation port identification bit of the physical port; a 3-bit storage space can be allocated to each physical port in the digital communication chip, and link aggregation port information of each physical port is stored for each physical port belonging to a link aggregation port; a 2-bit storage space can be allocated to each link aggregation port in the digital communication chip, and is used for storing the number of effective member ports matched with the link aggregation ports; the storage space with 20 bits can be allocated to each link aggregation port in the digital communication chip for storing all the alternative member ports matched with the link aggregation ports, and by adopting the storage mode and the storage space allocation mode, the storage space occupied by the link aggregation port information stored in the digital communication chip can be effectively reduced.
Further, after the data structure is set, the method may further include: and updating the data value of at least one of the first data structure, the second data structure, the third data structure, the fourth data structure and the fifth data structure according to the link aggregation port configuration update file.
Specifically, when the state of the physical port in the universal chip is changed correspondingly, an update file may be configured for the link aggregation port, and the data value of at least one of the first data structure, the second data structure, the third data structure, the fourth data structure, and the fifth data structure may be updated according to the update file.
S220, obtaining the target bitmap position of each target bit in the multicast group information in the bitmap form.
In a specific embodiment, if the digital-to-analog chip includes 32 physical ports, the multicast group information in the form of a bitmap may include 32 bitmap positions, and each bitmap position includes a bit represented as 0 or 1.
And S230, identifying at least one alternative physical port matched with each target bitmap position in the digital communication chip according to the mapping relation between the bitmap position and each physical port in the digital communication chip.
In a specific embodiment, in the multicast group information in the form of a bitmap, each bitmap position has a mapping relationship with one physical port in the digital-to-analog chip, and when bit information in at least one bitmap position is 1, at least one physical port having a mapping relationship with a bitmap position whose bit information is 1 is an alternative physical port.
S240, according to the query result of the link aggregation port identification bit of each alternative physical port, identifying the alternative physical port as a common physical port or a link aggregation port member port.
Specifically, if the link aggregation port identification bit of the currently queried target alternative physical port is the first identification value, the target alternative physical port is identified as the common physical port;
and if the link aggregation port identification bit of the currently inquired target alternative physical port is the second identification value, identifying the target alternative physical port as a link aggregation port member port.
S250, acquiring the currently processed member port of the target link aggregation port, and acquiring the target link aggregation port to which the member port of the target link aggregation port belongs.
S260, inquiring the number of the effective member ports matched with the target link aggregation port and all the optional member ports matched with the target link aggregation port.
S270, determining target member ports in all the alternative member ports according to the number of the effective member ports, and forwarding the copied message of the target message through the target member ports.
Wherein, according to the number of the valid member ports, determining the target member port among all the candidate member ports may specifically include:
generating a random number matched with the target message according to the message description information of the target message;
and calculating a remainder obtained by dividing the random number by the number of the effective member ports, and determining a target member port in all the candidate member ports which are sequentially arranged according to the offset of the remainder.
Optionally, the random number matched with the target packet may be generated according to the local area network address information of the target packet and according to a preset random number generation rule, and the range of the random number may be a positive integer greater than 0, but the generation method of the random number and the range of the random number are not specifically limited.
Optionally, if an invalid member port exists in all the candidate member ports and the target member port determined according to the remainder offset is an invalid member port, a new random number may be generated again to determine a new target member port until the determined target member port is a valid member port.
