Description
Technical Field
The present application relates to the field of network communication technologies, and in particular, to a method and an apparatus for an interface board to transmit a packet.
Background
The interface board is a board card for message transmission based on the exchange chip. The interface board includes a panel port and an internal port, where the panel port is an interface for physically connecting with an external device, for example, the panel port can be connected with the physical interface of the external device by using an optical fiber. The internal port is an interface for connecting with internal components in the equipment where the interface board is located.
The frame type switch is a device composed of a plurality of interface boards, a plurality of network boards and a backplane connector for connecting the interface boards and the network boards, and is mainly used for forwarding messages. Referring to fig. 1, fig. 1 is a schematic diagram illustrating connection between an interface board and a network board in a frame switch.
In practical application, before the interface board and the network board are connected, the throughput of each interface board and the throughput that a single network board can provide for each interface board need to be known, and then the number of the network boards that each interface board needs to be connected is determined.
For example, a frame switch now includes 3 interface boards, which are respectively an interface board 1, an interface board 2, an interface board 3, and 2 network boards, which are respectively a network board 1 and a network board 2. The interface board 1, the interface board 2, and the interface board 3 all have 32 board ports, and the throughput of each board port is 10G, so that it can be determined that the throughput of each interface board is 320G (10G × 32). The net plate 1 and the net plate 2 are respectively connected with 4 internal ports on each interface board, and the net plate 1 and the net plate 2 can provide 40G throughput for each internal port, so that it can be determined that the throughput that the net plate 1 and the net plate 2 can provide for each interface board is 160G (4 x 40G). The number of the screen boards required to be connected by each interface board can be determined to be 2(320G/160G is 2) according to the throughput of each interface board and the throughput that each screen board can provide for each interface board, that is, each interface board needs to be connected with the screen board 1 and the screen board 2, respectively, as shown in fig. 1.
In order to prevent the loop from being generated, the interface board usually aggregates the internal ports connected to the net board to generate an aggregate group. After the interface board receives the packet, in order to ensure that the flows transmitted by the internal ports in the aggregation group are balanced, hash calculation may be performed on the packet to determine the internal port through which the packet is transmitted.
When a certain interface board needs to transmit a received message to the other interface boards, the message needs to be transmitted to the network board connected to the interface board, and then the message is transmitted to the other interface boards through the network board.
For example, as shown in fig. 1, when the interface board 1 needs to transmit a message to the interface board 2 and the interface board 3, the interface board 1 can transmit the message to the interface board 1 and the interface board 2, and since the interface board 2 and the interface board 3 are both connected to the interface board 1 and the interface board 2, the interface board 1 and the interface board 2 can transmit the message to the interface board 2 and the interface board 3. Similarly, when the interface board 2 or the interface board 3 needs to transmit the received message to the other interface boards, the message may be transmitted to the network board connected to the interface board, and then the network board transmits the message to the other interface boards. In fig. 1, since each interface board is connected to each network board, messages that any interface board needs to transmit to other interface boards can be transmitted to other interface boards through the network board connected to the interface board.
When the number of the panel openings of the interface board 1 in fig. 1 is 16, the interface board 2 and the interface board 3 still have 32 panel openings, and the throughput of each panel port is 10G, it can be determined that the throughput of the interface board 1 is 160G, the throughput of the interface board 2 and the interface board 3 is 320G, the screen board 1 and the screen board 2 are respectively connected with 4 internal ports on each interface board, and the net board 1 and the net board 2 can provide the throughput of 40G for each internal interface, it can be determined that the throughput that the net board 1 and the net board 2 can provide for each interface board is 160G, depending on the throughput of each interface board and the throughput that the net board 1 and the net board 2 can provide for each interface board, it can be determined that the interface board 1 only needs to be connected with one screen, the interface board 2 and the interface board 3 both need to be connected with two screens, fig. 2 is a schematic diagram of connection between an interface board and a network board in another frame switch, as shown in fig. 2.
At this time, as shown in fig. 2, when the interface board 1 needs to transmit the received messages to the interface board 2 and the interface board 3, the interface board 1 may transmit the messages to the interface board 1, and then the interface board 1 transmits the messages to the interface board 2 and the interface board 3, respectively. Because the interface board 2 and the interface board 3 are transmitted to the screen board through the internal ports in a balanced manner, that is, the flow rates transmitted to the screen board by the internal ports are balanced, the messages transmitted to the screen board by the interface board 2 and the interface board 3 are shared by the screen board 1 and the screen board 2 on average. When the interface board 2 or the interface board 3 needs to transmit a received message to the interface board 1, the message shared by the interface board 1 can be successfully transmitted to the interface board 1 because of the physical connection between the interface board 1 and the interface board 1, whereas the message shared by the interface board 2 cannot be transmitted to the interface board 1 because of the absence of the physical connection between the interface board 1 and the interface board 2.
In order to ensure that any interface board can successfully transmit a message to other interface boards, in the prior art, the network board connected to the interface board with the least number of connected network boards is used as the network board for message transmission of each interface board, and the internal ports connected to other network boards on other interface boards are manually closed.
For example, as shown in fig. 2, the number of the screen connected to the interface board 1 is 1, and the number of the screen connected to the interface board 2 and the interface board 3 is 2, so that the screen 1 connected to the interface board 1 is used as a screen for transmitting messages by the interface board 1, the interface board 2, and the interface board 3, and then 4 internal ports connected to the screen 2 on the interface board 2 and the interface board 3 are closed.
However, except the internal ports connected to the interface board with the least number of the connection network boards are all used, the internal ports connected to other network boards on the other interface boards can all undertake the message transmission task, and are all closed to be in an idle state at this time, so that the internal ports connected to other network boards on the other interface boards are not fully used, and the internal port resources are wasted.

Example one
In order to solve the problems in the prior art, an embodiment of the present application shows a method for an interface board to transmit a packet, which is applied to a frame switch. Referring to fig. 3, fig. 3 is a flowchart illustrating a method for an interface board to transmit a packet according to an embodiment, and specifically executes the following steps:
step 301: when a message is received, judging the message type of the message;
in this embodiment, the frame switch includes a plurality of interface boards and a plurality of network boards. The interface board comprises a panel port and an internal port, the panel port is used for being connected with external equipment, and the internal port is used for being connected with a screen plate in the frame type switch. The interface board and the network board are usually connected to a plurality of internal ports, that is, a single interface board can transmit messages to a single network board through a plurality of internal ports.
In order to prevent a loop from occurring on an interface board, internal ports connected to a network board are aggregated to generate an aggregation group in a switch chip on the interface board, where the aggregation group includes the internal ports connected to the network board.
In this embodiment, the interface board aggregates the different connected screens to generate corresponding aggregation groups. For example, as shown in fig. 2, the interface board 2 is connected to the screen board 1 and the screen board 2, respectively, and if the interface board 2 is connected to the screen board 1 through the internal port 1, the internal port 2, the internal port 3, and the internal port 4, and connected to the screen board 2 through the internal port 5, the internal port 6, the internal port 7, and the internal port 8, the internal port 1, the internal port 2, the internal port 3, and the internal port 4 can be aggregated to form one aggregation group, and the internal port 5, the internal port 6, the internal port 7, and the internal port 8 can be aggregated to form another aggregation group, that is, the interface board aggregates to form the same number of aggregation groups based on the number of connected screen boards, and the internal port in each aggregation group is the internal port to which the interface board and the.
Since the logic executed by each interface board in the frame switch is the same, the execution logic of each interface board in the frame switch will be described below by describing the logic executed by one interface board.
When any interface board receives the message, the interface board can judge the message type of the message; in the present application, the packet types are divided into two types, the first type is a broadcast type, an unknown unicast type, and a multicast type, and the second type is a known unicast type.
When the interface board receives the first type of packet, it needs to transmit the packet to each other interface board except itself in the frame switch. When the interface board receives the second type of message, only the message needs to be transmitted to the specified interface board.
Because there is no direct physical connection between the interface boards, the message transmission cannot be directly performed, and the message needs to be transmitted indirectly through the network board, therefore, after the interface board determines the type of the received message, it needs to determine the target network board of the message, that is, it needs to determine to which network board or which network boards the message is transmitted.
Step 302: determining a target network board of the message based on the message type;
in this embodiment, each interface board stores the corresponding relationship between each interface board and the connected network board in the frame switch.
After the interface board determines the target interface board of the message according to the type of the received message, the interface board can obtain the network board connected with the board from the corresponding relationship between the board and the network board connected with the board, and obtain the network board connected with the target interface board from the corresponding relationship between the target interface board and the network board connected with the target interface board.
In order to ensure that the message to be transmitted by the interface board can be accurately transmitted to the target interface board, the network board for transmitting the message must be the network board connected to both the interface board and the target interface board.
Therefore, after the interface board obtains the screen board connected with the board and the screen board connected with the target interface board, the interface board can perform intersection operation on the screen board connected with the board and the screen board connected with the target interface board to obtain the target screen board, and the target screen board is the screen board connected with both the board and the target interface board.
When the interface board determines that the type of the received packet is a broadcast packet, an unknown unicast packet, or a multicast packet, the interface board may determine that a target interface board of the received packet is each of the other interface boards except the local board in the frame switch. In order to ensure that the messages received by the interface board can be accurately transmitted to other interface boards, the target network board for transmitting the messages must be the network board connected to each interface board in the frame switch.
For example, as shown in fig. 2, when the interface board 2 interfaces to a broadcast packet, an unknown unicast packet, or a multicast packet, the interface board 2 needs to transmit the received packet to the interface board 1 and the interface board 3. In order to ensure that the received message can be accurately transmitted to the interface board 1 and the interface board 3, the network board for transmitting the message must be the network board connected to all of the interface board 1, the interface board 2, and the interface board 3, and therefore, the target network board of the message received by the interface board 2 is the network board 1.
When the interface board determines that the type of the received message is a known unicast message, the interface board may determine that a target interface board of the received message is a certain designated interface board in the frame switch. The interface board can search for the interface board corresponding to the received message based on the message characteristics in the message. In order to ensure that a message received by an interface board can be accurately transmitted to the interface board corresponding to the message, a target network board for transmitting the message must be a network board connected with both the local board and the interface board corresponding to the message.
For example, as shown in fig. 2, when an interface board 2 interfaces a known unicast message and a target interface board of the message is an interface board 1, since the interface board 1 is connected to the interface board 1 and the interface board 2, the interface board 2 can determine that the interface board transmitting the message is the interface board 1. When the interface board 2 interfaces a known unicast message and the target interface board of the message is the interface board 3, since the interface board 2 is connected to the network board 1 and the network board 2 and the interface board 3 is connected to the network board 1 and the network board 2, the interface board 2 can determine that the network board transmitting the message is the network board 1 and the network board 2.
Step 303: and transmitting the message to the target network board.
In this embodiment, after the interface board determines the target network board, the transmission mode of the message may be determined according to the target network board, and then the message is transmitted to the target network board based on the transmission mode.
In this embodiment, the interface board aggregates the different connected screens to generate corresponding aggregation groups. After the interface board determines the target network board, the interface board can determine the target aggregation group for transmitting the message. In order to fully utilize the internal port resources, the interface board may distribute the received messages to each aggregation group in a balanced manner based on a load balancing principle, and the messages distributed to each aggregation group are transmitted to the network board by each internal port in each aggregation group in a balanced manner.
For example, as shown in fig. 2, when the interface board 2 needs to transmit a message to the interface board 3, an internal port on the interface board 2 connected to the network board 1 aggregates to generate an aggregation group 0, and an internal port connected to the network board 2 aggregates to generate an aggregation group 1. The messages received by the panel ports with odd serial numbers on the interface board 2 are distributed to the aggregation group 0, and the messages received by the panel ports with even serial numbers are distributed to the aggregation group 1. The message distributed to the aggregation group 0 is transmitted to the network board 1 through the internal port thereof in a balanced manner, and the message distributed to the aggregation group 1 is transmitted to the network board 2 through the internal port thereof in a balanced manner.
The application range of the technical scheme provided by the embodiment of the application is not limited by the number of the interface boards and the screen boards.
For example, as shown in fig. 4, fig. 4 is a schematic diagram illustrating connection between an interface board and a network board in another frame switch.
As shown in fig. 4, the interface board 1 is connected to the screen 1, the interface board 2 is connected to the screen 1 and the screen 2, and the interface board 3 is connected to the screen 1, the screen 2, and the screen 3. When any interface board receives broadcast message, unknown unicast message or multicast message, the network board transmitting message is the network board 1. When the interface board 1 receives a known unicast message sent to the interface board 2 or the interface board 3, or the interface board 2 or the interface board 3 receives a known unicast message transmitted to the interface board 1, the network board transmitting the message can only be the network board 1. When the interface board 2 receives a known unicast message transmitted to the interface board 3 or the interface board 3 receives a known unicast message transmitted to the interface board 2, the network boards transmitting the messages may be the network board 1 and the network board 2.
As can be seen from the technical method shown in the first embodiment, when any interface board receives a message, the interface board determines a target interface board of the message according to the type of the message, then determines a target network board for transmitting the message according to the corresponding relationship between the interface board and the network board connected to the interface board and the corresponding relationship between the target interface board and the network board connected to the target interface board, determines a transmission mode of the message according to the target network board, and finally transmits the message to the target network board based on the transmission mode. In the application, in order to fully utilize the internal port, the optimal transmission mode of the message is determined in advance according to the corresponding relation between the interface board and the connection network board thereof and the target network board for transmitting the message when each interface board receives different types of messages, so that the internal port resources on the interface board in the frame switch can be fully utilized compared with the prior art.
