Fig. 1 is a schematic diagram of a card board architecture in a convergence/diversion apparatus according to an embodiment of the present invention, including at least one input source card board, at least one conversion screen board, and at least one target card board. The source card board is used for receiving messages, the conversion network board is used for carrying out message transmission between the source card boards or between the source card board and the target card board, and the target card board is provided with an output interface used for outputting the messages. In addition, the conversion network board can also be provided with an output interface for outputting messages. The source card board is provided with an input interface for receiving messages, and the conversion network board and the target card board can be both provided with an output interface for the messages.
Two source cards, source card a1 and source card b2, are included in the example of FIG. 1; the two conversion screen plates are respectively a conversion screen plate c3 and a conversion screen plate d 4; two target cards, target card e5 and target card f6, respectively.

Example one
Fig. 2 is a flowchart of a message processing method according to an embodiment of the present invention, where this embodiment is applicable to a case where a message is transmitted in a convergence and offloading device, especially a case where the message is copied and transmitted, and the method may be executed by a terminal, where the terminal has a function of the convergence and offloading device, and the terminal may be a converter, a computer device, or the like. The method is applied to a current clamping plate, wherein the current clamping plate can be a source clamping plate, a conversion screen plate or a target clamping plate, and the method specifically comprises the following steps:
and step 110, judging whether the cross-board forwarding is needed or not according to the received original message.
The current card board analyzes the received message to obtain routing information, whether an outgoing interface of the message is on the current card board is judged according to the routing information, and if the outgoing interface of the original message is not on the current card board, cross-board forwarding is determined to be needed. If cross-board forwarding is required, step 120 is performed. If no cross-board forwarding is required, step 130 is performed.
And step 120, if the cross-board forwarding is needed, adding a target message header to the original message to obtain a target message, wherein the target message header comprises routing information needed by a next hop card of the current card.
And if the cross-board forwarding is needed, adding a target message header to the original message, wherein the routing information included in the target message header can provide reference for the next hop card to determine whether the target message needs to be forwarded in a cross-board mode. The next hop card board for receiving the target message can be determined according to a pre-configured routing table. The next hop card can identify the routing information and determine whether the board needs to be crossed according to the routing information. And the rest is done until the message is sent to the target card. The target card board is provided with a message output interface. After adding the target packet header to the original packet to obtain the target packet, step 140 is executed.
It should be noted that the original message of the current card board may be a target message output by a previous card board of the current card board, and the target message obtained by the current card board may be used as the original message of a next card board. Illustratively, when the target message obtained by the source card board is transmitted to the conversion network board, the target message is used as the original message of the conversion network board.
And step 130, if the cross-board forwarding is not needed, outputting the message content of the original message through the local port of the current card board.
If the cross-board forwarding is not needed, the output interface is located in the current card board, and the current card board outputs the message content of the original message through the local port. If the current card board is a conversion network board or a target card board, the original message received by the current card board includes a target message header added by the previous card board, and the message content at the moment refers to a message with the target message header removed. In other words, the target packet header is used to transmit the routing information required by the next hop of card between the cards in the convergence and shunt device, and the data stream output by the convergence and shunt device does not include the target packet header, so that the packet content of the original packet is output, that is, the packet that does not include the target packet header is output.
And step 140, sending the target message to a next hop card board.
And sending the target message to a next hop card board according to a pre-configured message transmission path.
The message processing method provided by the embodiment of the invention judges whether the message needs to be forwarded across boards or not according to the received original message; if the cross-board forwarding is needed, adding a target message header to the original message to obtain a target message, wherein the target message header comprises routing information needed by a next hop card of the current card; if the cross-board forwarding is not needed, outputting the message content of the original message through the local port of the current card board; and sending the target message to a next hop card board. Compared with the prior art that each card board on a message transmission path needs to be manually configured, the message processing method provided by the embodiment of the invention can determine whether the board spanning is needed or not according to the output interface of the message when the message is transmitted, can automatically add a target message header to the original message when the board spanning forwarding is needed, and can enable a next-hop card board to acquire the transmission path of the target message by adding the routing information needed by the next-hop card board in the target message forwarding, thereby completing the transmission of the target message among different card boards in the convergence and diversion device. The automatic message transmission is realized according to the outgoing interface of the message, the configuration of routing information by accessing each card board by a user is not needed, and the message processing efficiency is improved.
Example two
Fig. 3 is a flowchart of a message processing method according to a second embodiment of the present invention, and as a further description of the foregoing embodiment, a current network card may be a source card board, and determines whether cross-board forwarding is required according to a received original message, where the method includes: judging whether a target multicast tree is hit or not according to address information in the received input message; if the target multicast tree is hit, judging whether cross-board forwarding is needed or not according to the structure of the target multicast tree; correspondingly, if the cross-board forwarding is needed, adding a target message header to the original message to obtain a target message, including: if cross-board forwarding is needed, determining a first multicast tree identifier matched with a switching network board according to a target multicast tree, wherein the switching network board is a next hop card board of a source card board in the target multicast tree; generating a first message header according to the first multicast tree identifier; generating a first message according to the first message header and the input message; correspondingly, the sending of the target message to the next hop card board includes: and sending the first message to the conversion network board according to the port information of the pre-configured conversion network board.
The above method may be carried out by:
step 210, determining whether the target multicast tree is hit according to the address information in the received input message.
After the source card board receives the message, the message is analyzed to obtain address information. And judging whether the target multicast tree is hit or not according to the address information. The address information may be a source address or a destination address of the data packet, and the address information may also be address information of an interface that receives the packet. The mapping relationship between a plurality of address information and the multicast tree may be configured in advance, including the mapping relationship between the address information and the target multicast tree. If the pre-configured address information contains address information obtained by analyzing the message, determining a target multicast tree corresponding to the address information according to a pre-configured mapping relation, and determining that the address information hits the target multicast tree.
And step 220, if the target multicast tree is hit, judging whether cross-board forwarding is needed according to the structure of the target multicast tree.
And if the target multicast tree is hit, acquiring the structure of the target multicast tree. The structure of the target multicast tree is used for describing a card board to which the message needs to be sent, and the card board can be a source card board, a conversion network board and a target card board. And judging whether the target multicast tree contains cards except the current source card. If there is, for example, a card in the target multicast tree including a switch board or a target card, it is determined that cross-board forwarding is required. And if the target multicast tree only contains the source card board, determining not to carry out cross-board forwarding.
Step 230, if cross-board forwarding is required, determining a first multicast tree identifier adapted to the switching network board according to the target multicast tree, and enabling the switching network board to be a next hop card board of a source card board in the target multicast tree.
The target multicast tree can be stored through a data structure such as a linked list, and the current source card board and the next hop card board of the current card board in the target multicast tree can be determined by traversing the target multicast tree.
Optionally, the target multicast tree is composed of multiple cards and their association relationships, so that the first multicast tree identifier of the first multicast tree in which the next-hop card of the current source card is the root node can be determined according to the target multicast tree. The multicast tree identification of each card node as the root node may be recorded in the target multicast tree. And searching the first multicast tree identifier of the first multicast tree of which the next hop card board of the current source card board is the following point by traversing the target multicast tree. And assuming that the next hop card board is the conversion screen board, the root node of the first multicast tree represented by the first multicast tree identifier is the conversion screen board.
Step 240, generating a first header according to the first multicast tree identifier.
The first header includes a combination of one or more of the following parameters: the method comprises the steps of message type, reserved field, global port information, first multicast tree identification, load balancing group identification, data stream identification, hash value and upper layer message protocol identification.
Wherein the message type is used to indicate the type of the first message. The reserved field is used for byte alignment. And if the next hop card has the global port, the message is encapsulated according to the upper layer message protocol identifier, the first message header is removed, and the encapsulated message is output. And if the next-hop card does not contain the global port, continuing to transmit the message until the message is sent to the card with the global port and outputting the message through the global port.
The load balancing group mark is used for indicating that the next hop is a load balancing group formed by a plurality of conversion network boards. And using a plurality of conversion network boards in the load balancing group to process the messages in the data flow in parallel, wherein the plurality of conversion network boards in the load balancing group process the data flow containing the messages in an apportioned mode. The data flow identifier is used for identifying the data flow where the message is located. The data stream identifier may be used to identify packets belonging to the same data stream according to the data stream identifier after the packets are processed by the load balancing group.
The hash value may be a hash value of the IP address in the message, and is used for performing the verification.
Step 250, generating a first message according to the first message header and the input message.
And adding the first message header into the input message to generate a first message.
And step 260, sending the first message to the conversion network board according to the port information of the conversion network board configured in advance.
And the port information of the pre-configured conversion screen is used for sending the data of the current source card to the conversion screen of the next hop. Data transmission is carried out between the source clamping plates and the target clamping plates, and the data transmission is carried out through the conversion screen plates. The port information of the current source card board and the conversion screen board can be configured in advance. For example, a message may be sent to the switching network board from a port of the current source card. The first message can be rapidly and accurately sent to the conversion network board through the pre-configured port information.
In one implementation, step 260, sending the first message to the conversion network board according to the port information of the conversion network board configured in advance, may be implemented as:
determining a next hop network board of a source card board as a balance group according to a target multicast tree, wherein the balance group comprises a plurality of conversion network boards which share the flow of a first message; and respectively sending the first message to the plurality of conversion network boards according to the port information of the plurality of conversion network boards which are pre-selected and configured.
The message processing method provided by the embodiment of the invention can add the first message header to the message in the source card board to generate the first message. The first message header is used for representing the routing information used by the conversion network board. The source card board can generate a first message header more accurately according to the first multicast tree identification of the target multicast tree, and provides more accurate routing information for the switching network board.
Further, before determining whether the target multicast tree is hit according to the address information in the received input message in step 210, the method further includes: acquiring a plurality of pieces of field information of a received input message; and performing access control list ACL lookup according to the plurality of field information, and judging whether the target multicast tree is hit or not according to the address information in the received input message if the access control list ACL lookup is successful.
An Access Control List (ACL) may be configured in advance. The access control list is an access control technology based on packet filtering, and can filter data packets on an interface according to set conditions. The user can pre-configure the access control list according to the use requirement. When the message is input, the table look-up of the access control list is carried out, and if the access control list contains the address information (source address or destination address) in the original message, the original message is determined to be allowed to be processed. Otherwise, if the access control list does not contain the address information in the original message, the forwarding of the original message is cancelled, and the message copying process is ended.
The message can be filtered through the access control list, so that the message copying is more targeted, and the usability is improved. Meanwhile, the access control list can prevent data transmission of unknown data sources, and network security is improved.
In one implementation, the message traffic may be split by the balancing group, and the message traffic is shared by a plurality of switching network boards in the balancing group, so as to improve the message processing speed. At this time, the first message is sent to the conversion network board according to the port information of the conversion network board configured in advance, which can be implemented as follows: determining a next hop network board of a source card board as a balance group according to a target multicast tree, wherein the balance group comprises a plurality of conversion network boards which share the flow of a first message; and respectively sending the first message to the plurality of conversion network boards according to the port information of the plurality of conversion network boards which are pre-selected and configured.
The first message flow can be forwarded through one conversion network board, and a load balancing group formed by a plurality of conversion network boards can also be used. And traversing the target multicast tree, and if the next hop network board of the source card board is a balanced group, determining a plurality of switching network boards included in the balanced group according to the target multicast tree. And respectively sending the first message to a plurality of conversion network boards according to the port information of the conversion network boards configured in advance.
It should be noted that the load balancing group is configured to split the data stream, so that the first messages can be respectively sent to the multiple switching network boards according to a certain proportion, and a total flow of the load balancing group is the same as a flow of an original message received by the source card board.
According to the embodiment of the invention, the problem that the data stream cannot be quickly forwarded to the next hop card board by the conversion screen board due to overhigh flow is avoided through the load balancing group, and the flow processing efficiency is improved.
