In this embodiment, as shown in fig. 1, a first network bridge 17 and a second network bridge 18 are respectively disposed on a first network card 13 and a second network card 14 of a server 11, a first port 21 of the first network bridge 17 and a first port 23 of the second network bridge 18 are bound into an aggregation port 29 of the server 11, the aggregation port 29 has an interface with an application processor 31, and a second port 22 of the first network bridge 17 and a second port 24 of the second network bridge 18 have an interface with an application loading processor 33.
Step 202, configuring a forwarding flow table on the second bridge of each server to forward the application access request message received by the second network card of each server to the aggregation port of each server.
In this embodiment, a forwarding flow table is configured on the second bridge of each server, and is used to modify the source address of the application access request message, so that the application access request message is forwarded to the aggregation port of each server.
The message processing method provided by the invention is characterized in that a first network card of a server is correspondingly provided with a first network bridge, a second network card of the server is correspondingly provided with a second network bridge, each network bridge comprises two ports, the first port of each network bridge is bound into an aggregation port, the address of the aggregation port is set as the address of the first network card of each server, each aggregation port has an interface with an application processor, the second port of each network bridge has an interface with an application loading processor, a forwarding flow table is configured on the second network bridge of each server, so that an application access request message received by the second network card of each server is forwarded to the aggregation port of each server to complete data interaction between the two servers, and when network load balance is realized, under the condition that one server cannot bind a plurality of network cards by adopting an IEEE802.3ad protocol, normal data communication can be carried out between the servers.
In addition, the gateway device 41 and the gateway device 42 in fig. 1 may be, for example, switches, and the present invention is not particularly limited herein with respect to a specific type of the gateway device.
Fig. 3 is a flowchart illustrating a second embodiment of a message processing method according to the present invention, in this embodiment, based on the system shown in fig. 1, as shown in fig. 3, the method of this embodiment may include:
step 301, receiving an application loading message sent by a second server through a first network card of a first server.
In this embodiment, when the second server sends the application loading message to the first server, the application loading message is sent to the gateway device, and then the gateway device sends the application loading message to the first network card of the first server. The application loading message may be, for example, a pre-boot execution environment PXE message.
Step 302, sending an application load message to the application load processor through a second port of the first bridge of the first server.
In the actual application process, the second server cannot bind the two network cards through the IEEE802.3ad protocol for some reasons, for example, the second server may be directly accessed by a bare computer, the kernel version of the linux Operating System is lower than 2.4, or the Operating System (OS for short) uses other Operating systems that do not support internet access binding. In the prior art, if the second server cannot bind the two network cards, the first server cannot normally communicate with the second server, which results in blocking of services. In this embodiment, by setting the first bridge in the open virtual switching standard mode on the first network card of the first server, after the second server sends the application loading message to the gateway device, the first network card of the first server receives the application loading message and sends the application loading message to the first bridge of the first server. When the first bridge of the first server receives the application loading message, the application loading message is broadcasted from the first port and the second port in a broadcasting mode, because an interface exists between the second port and the application loading processor, the application loading message broadcasted from the first port is automatically discarded, and the application loading message is sent to the application loading processor through the second port of the first bridge of the first server so as to check the application loading message by the application loading processor to verify whether the message is correct or not. Wherein the application loading processor may be implemented by software and/or hardware. The following describes the case of direct bare-metal access to the server 12 in fig. 1 as an example.
When the server 12 accesses the server system, the server 12 automatically installs the operating system through the server 11. In a specific implementation process, after the application loading message is started through the first network card 15 of the server 12, the server 12 sends the application loading message to the gateway device 41, which may be, for example, a switch. After receiving the application loading message, the gateway device 41 sends the application loading message to the server 11 through the first network card of the first server and the second port of the first bridge of the first server.
Step 303, the second port of the first bridge of the first server receives the response message of the application loading message, and sends the response message of the application loading message to the second server through the first network card of the first server.
In this embodiment, after the application loading message is sent to the application loading processor 33 through the second port 22 of the first bridge 17 of the server 11, the application loading processor 33 processes the application loading message to obtain a response message of the application loading message, and sends the response message of the application loading message to the second port 22 of the first bridge 17 of the server 11, and after the second port 22 of the first bridge 17 of the server 11 receives the response message of the application loading message, the response message is sent to the gateway device 41 through the first network card 13 of the server 11, so that the gateway device 41 returns the response message of the application loading message to the second server. After the first network card of the second server receives the response message of the application loading message, it indicates that the application loading message sent by the first network card of the second server is responded, thereby completing the interaction of the application loading message in one period, so that the server 12 can configure the local operating system according to the response message of the application loading message, thereby implementing normal data communication between the first server and the second server, and thus, the first server and the second server can communicate by using any communication protocol as actually required.
It should be noted that, in this embodiment, a first physical channel between two servers is taken as an example of a transmission path of an application loading message, that is, an application loading message is sent through a first network card of a second server and received by the first network card of the first server, similarly, if an application loading message is sent by a second network card on the second server, the application loading message is received through a second network card of the first server and sent to an application loading processor through a second port of a second network bridge of the first server, a response message of the application loading message is received by a second port of the second network bridge of the first server and sent to the second server through the second network card of the first server, that is, a second physical channel between two servers is taken as a transmission path of the application loading message, the specific processing manner is similar to the processing manner in which the first physical channel is used as the transmission path of the application loading message, and is not described here again.
The message processing method provided by the embodiment of the invention comprises the steps of correspondingly arranging a first network bridge on a first network card of a server, correspondingly arranging a second network bridge on a second network card of the server, enabling an interface to exist between a second port of each network bridge and an application loading processor, receiving an application loading message sent by a second server through the first network card of the first server, sending the application loading message to the application loading processor through the second port of the first network bridge of the first server, receiving a response message of the application loading message through the second port of the first network bridge of the first server, sending the response message of the application loading message to the second server through the first network card of the first server, completing data interaction, and achieving the purpose that when network load balance is realized, under the condition that one server cannot bind a plurality of network cards by adopting an IEEE802.3ad protocol, normal data communication can be carried out between the servers.
Fig. 4 is a flowchart illustrating a third embodiment of a message processing method according to the present invention, and this embodiment describes, in detail, an embodiment in which after the interaction of the application loading message is completed, an application access request message is sent to the first server through the first network card of the second server, so that normal data communication is performed between the two servers, and network load balancing is implemented, on the basis of the embodiment illustrated in fig. 3. The structure of the server system applied in this embodiment is similar to that in fig. 1, and is not described herein again, as shown in fig. 4, the method in this embodiment may include:
step 401, receiving an application access request message sent by a second server through a first network card of a first server.
In this embodiment, when the interaction of the application loading message is completed between the first server and the second server, and the first network card of the second server is correspondingly provided with the first network bridge, and the second network card is correspondingly provided with the second network bridge, after the first port of each network bridge is bound to form the aggregation port, the application processor on the second server starts to initiate an application access request, and sends an application access request message to the first server. In practical application, a load balancing policy is further configured on the aggregation port of the second server, and specifically, a binding mode of the aggregation port of the second server may be set as a balance policy balance-xor. The aggregation port of the second server can select whether to send the application access request message to the first server through a first network card of the second server or through a second network card of the second server according to the balance-xor policy. In a specific implementation process, a first Media Access Control (MAC) address of a first network card of a second server and a second MAC address of a second network card of the second server are processed as follows: (the first MAC address is XOR with the second MAC address)% of the number of the network cards in the second server is selected according to the obtained calculation result. For example: in this embodiment, since the number of the network cards in the second server is 2, after performing xor processing on the first MAC address of the first network card of the second server and the second MAC address of the second network card of the second server, if the obtained result is 0, the application access request message is sent to the first server through the first network card of the second server, and if the obtained result is 1, the application access request message is sent to the first server through the second network card of the second server. In this embodiment, an example in which the aggregation port of the second server sends the application access request message to the first server through the first network card of the second server is described.
After the application access request message is sent to the gateway device through the first network card of the second server, the gateway device sends the received application access request message to the first network card of the first server through the first physical channel between the two servers.
Step 402 sends an application access request message to an aggregation port of a first server through a first port of a first bridge of the first server.
In this embodiment, a first network card of the first server is provided with a first bridge, a second network card of the first server is provided with a second bridge, and the first port of each bridge is bound into one aggregation port. And after the first network card of the first server receives the application access request message, the application access request message is sent to the aggregation port of the first server through the first port of the first bridge of the first server.
In step 403, the aggregation port of the first server sends the application access request to the application processor.
In this embodiment, since an interface exists between the aggregation port of the first server and the application processor, after the aggregation port of the first server receives the application access request message, the application access request message is reported to the application processor, where the application processor may be implemented by software and/or hardware. And the application processor processes the received application access request message to obtain a response message of the application access request message.
Step 404, after the aggregation port of the first server receives the response message of the application access request message sent by the application processor, the first network card of the first server or the second network card of the first server is selected to forward the response message of the application access request message to the second server according to the load balancing policy.
In this embodiment, a load balancing policy is configured on the aggregation port of the first server, and after the application processor sends the generated response message of the application access request message to the aggregation port of the first server, the aggregation port of the first server selects, according to the configured load balancing policy, to pass through the first network card of the first server or the second network card of the first server, and sends the response message of the application access request message to the gateway device, so that the gateway device returns the response message of the application access request message to the second server. In a specific implementation process, configuring a load balancing policy on an aggregation port of a first server, which may be implemented by setting a binding mode of the aggregation port of the first server to be a balancing policy balance-xor, and according to the balancing policy, performing the following processing on a first MAC address of a first network card of the first server and a second MAC address of a second network card of the first server: (the first MAC address XOR and the second MAC address)% of the number of the network cards in the first server, and the aggregation port of the first server selects to forward the response message of the application access request message to the second server through the first network card of the first server or the second network card of the first server according to the obtained calculation result. For example: in this embodiment, since the number of the network cards in the first server is 2, after performing exclusive or processing on the first MAC address of the first network card of the first server and the second MAC address of the second network card of the first server, if the obtained result is 0, the response message of the application access request message is forwarded through the first network card of the first server, and if the obtained result is 1, the response message of the application access request message is forwarded through the second network card of the first server.
After the second server receives the response message of the application access request message, it is indicated that the application access request message is responded, that is, the interaction of the application access request message in one period is completed, so that it can be seen that not only normal data communication can be performed between the first server and the second server, but also network load balance between the servers can be realized.
The message processing method provided by the embodiment of the invention receives an application access request message sent by a second server through a first network card of a first server, sends the application access request message to an aggregation port of the first server through a first port of a first bridge of the first server, sends the application access request message to an application processor through the aggregation port of the first server, processes the application access request message by the application processor, sends a response message of the application access request message to the aggregation port of the first server, and the aggregation port of the first server selects the first network card of the first server or a second network card of the first server to forward the response message of the application access request message to the second server according to a load balancing strategy so as to complete data interaction, so that when network load balancing is realized, under the condition that one server cannot bind a plurality of network cards by adopting an IEEE802.3ad protocol, normal data communication can be carried out between the servers, so that the problem of service blockage in the prior art is solved.
