In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Fig. 3 is a flow diagram of the implementation of various traffic handling functions in a network in one embodiment of the invention. Referring to fig. 2 and fig. 3, the following describes in detail a specific implementation process for implementing multiple service processing functions in the present invention with reference to the device of the present invention, where the process specifically includes the following steps:
step 301: a multi-core processor device is provided in a network.
In this step, the multi-core processor device includes a configuration management unit, a packet distribution unit, and a multi-core processor.
Step 302: a License (License) certificate of the multi-core processor device is obtained.
Here, in order to provide different levels of service for different users, one License certificate may be provided by the operator for each user using the multicore processor device.
The License certificate provided by the operator can be directly used for executing the configuration of the subsequent service processing function, so that the information of the service processing function corresponding to each core in the multi-core processor can be recorded.
Step 303: and configuring different business processing functions of each core of the multi-core processor in the multi-core processor equipment by using the License certificate.
In this step, the License certificate is directly used for configuration, and the method specifically includes: when the multi-core processor is started, loading an operating system and service software corresponding to the service processing function for each core in the multi-core processor according to the information of the service processing function corresponding to each core in the License certificate.
In the above step 302, the License certificate provided by the operator may be used to limit the configuration of the subsequent service processing function of the user, that is, only information about the service processing function authorized by the user, instead of the configuration for executing the subsequent service processing function, that is, information about the service processing function corresponding to each core in the multi-core processor is not described, in which case, the process of the step 303 is implemented by replacing the following process:
the method I is realized by using a configuration file, and comprises the following steps:
A. configuration parameters are set in a configuration file of the multi-core processor device in advance, and the configuration parameters are used for representing service processing functions corresponding to cores in the multi-core processor.
B. When the multi-core processor is started, the configuration management unit in the device can read the configuration file from a BOOT (BOOT) start menu, and determines that the configured service processing functions are respectively loaded for each core in the multi-core processor according to the configuration parameters in the configuration file.
C. Before loading the operating system and the service software of the corresponding service processing function for each core, judging whether the information of the service processing function needing to be loaded and configured currently can be found in the authorized service processing function information in the License certificate by the configuration management unit, if so, executing the step D, otherwise, executing the step E.
D. And loading an operating system and service software corresponding to the service processing function for the core in the multi-core processor according to the configuration parameters.
E. And prompting the user of the information of insufficient authority and failure.
The second mode is realized by hardware configuration, and comprises the following steps:
a. setting a hardware configuration parameter on a hardware single board of the multi-core processor device in advance, wherein the hardware configuration parameter represents service processing functions corresponding to cores in the multi-core processor.
b. When the multi-core processor equipment is started, the configuration management unit of the equipment reads the hardware configuration parameters on the hardware single board, and determines the service processing functions which need to be loaded and configured for each core in the multi-core processor respectively at present according to the hardware configuration parameters.
c. Before loading the operating system and the service software of the corresponding service processing function for each core, judging whether the information of the service processing function needing to be loaded and configured currently can be found in the authorized service processing function information in the License certificate by the configuration management unit, if so, executing the step d, otherwise, executing the step e.
d. And loading an operating system and service software corresponding to the service processing function for the core in the multi-core processor according to the hardware configuration parameters.
e. And prompting the user of the information of insufficient authority and failure.
In the second mode, the set hardware configuration parameter may be a status word indicated by the dial switch, for example, it is necessary to set core 0 in the multi-core processor as the router function, and set core 1 of the multi-core processor as the firewall function, and when the status word indicated by the dial switch is predetermined to be 6 and 7, the status word indicated by the dial switch corresponding to core 0 may be set to be 6, and the status word indicated by the dial switch corresponding to core 1 may be 7.
In addition, the set hardware configuration parameters may also be register configuration words of internal devices of the logic device, that is, different functions to be executed by different cores in the multi-core processor are represented by different configuration words. In addition, the set hardware configuration parameters may also be hardware resource configuration parameters of the hardware interface daughter card, that is, different functions that different cores in the multi-core processor need to execute are represented by different parameter values of the hardware resource configuration parameters.
The process of this step 303 is the original configuration performed before the multi-core processor device is started.
Step 304: in the operation process of the multi-core processor, a management terminal connected with the multi-core processor receives a control command which is input by a user and comprises the address of a designated core in the multi-core processor and configuration parameters, and sends the control command to the multi-core processor device.
Step 305: the multi-core processor device sends the control command to the designated core.
Step 306: and the appointed core executes corresponding updating configuration processing according to the received control command.
The processing of steps 304, 305, and 306 is processing performed in the operation process of the multi-core processor device according to the present invention, which needs to update the configuration of a core, such as updating a service processing function or updating a routing forwarding table.
FIG. 4 is a schematic diagram of a first preferred structure of a multi-core processor device in one embodiment of the invention. Referring to fig. 4, in order to implement the processing of step 304 to step 306, a virtual management interface module and a management physical interface are included in the multi-core processor device, wherein the management physical interface is connected to an external management terminal.
Thus, referring to fig. 4, when a user needs to update the configuration of one core, for example, in an initial configuration, the service processing function executed by the core 0 is a firewall function, and the user needs to change the service processing function executed by the core 0 to IPS processing, a control command including a core 0 address and used for configuring the service processing function of the core 0 to IPS processing may be input to the management terminal connected to the multi-core processor device, and the external management terminal sends the control command to the management physical interface of the multi-core processor device; the management physical interface of the multi-core processor device sends the control command to the virtual management interface module; the virtual management interface module sends the control command to the core 0 according to the address of the core 0 carried in the control command, and the core 0 executes corresponding service processing according to the received control command, namely, an operating system and service software for realizing an IPS function are loaded.
In an actual service implementation, when a user inputs a control command to an external management terminal connected to a multi-core processor, the user may directly input the control command in a serial format locally at the management terminal, so that the type of the management physical interface shown in fig. 4 is a serial interface, the control command in the serial format is received and sent, and the control command in the serial format is received and sent by the virtual management interface module shown in fig. 4.
When a user inputs a control command to an external management terminal connected to a multi-core processor, the user may input an ethernet-type control command to the management terminal through a remote input mode, such as logging in a Web interface, so that the type of the management physical interface shown in fig. 4 is an ethernet interface, the ethernet-type control command is received and sent, and the ethernet-type control command is received and sent by the virtual management interface module shown in fig. 4.
Step 307: in the running process of the multi-core processor equipment, the multi-core processor equipment receives a message sent from the outside.
Step 308: and the multi-core processor equipment sequentially sends the messages to each core in the multi-core processor for executing each service processing function for processing according to the preset execution sequence of each service processing function.
FIG. 5 is a schematic diagram of a third preferred structure of a multi-core processor device in one embodiment of the invention. Referring to fig. 5, the multi-core processor device may further include, on the basis of the structure shown in fig. 4, a virtual ethernet interface module connected to all cores that perform a service processing function, so that, with the structure shown in fig. 5, the specific implementation of the step 307 and the step 308 includes:
the message distribution unit receives a message sent from the outside on an external physical interface and sends the message to a core 0 corresponding to the first executed service processing function;
a forwarding table is stored in the core 0, and the forwarding table includes an address (IP address or MAC address) of a core, such as the core 1, corresponding to a next service processing function to be executed, so that, after the core 0 receives a message and performs corresponding service processing on the message, for example, firewall processing, the core 0 encapsulates the address of the core 1 in the message according to the forwarding table, and then sends the message to the virtual ethernet interface module through a virtual logic port pre-allocated to the core 0;
after receiving the message sent by the core 0, the virtual Ethernet interface module sends the message to the core 1 according to the address of the core 1 encapsulated in the message;
if the core 1 is not the last core for executing the service processing function, the core 1 performs processing similar to that of the core 0, that is, firstly, according to the loaded service processing function, corresponding service processing such as antivirus processing is performed on the received message, then, according to a stored forwarding table including the address of the core corresponding to the next service processing function to be executed, the address of the next core is packaged in the message, and the message is sent to the virtual Ethernet interface module through a virtual logic port which is pre-allocated to the core;
after receiving the message sent by the core 1, the virtual Ethernet interface module sends the message to a next core, such as a core n, according to the address of the next core encapsulated in the message;
if the core n is the last core executing the service processing function, the core n performs corresponding service processing on the received message according to the loaded service processing function, and then sends the message to the outside of the multi-core processor device through a physical interface pre-allocated to the core n.
With the structure shown in fig. 5, the present invention can achieve load balancing of a specified service processing function. In this case, in step 303, when configuring the corresponding core for the specified service processing function requiring load balancing, the configuration management unit needs to further configure a plurality of cores in the multi-core processor, where the plurality of cores should have the same address, and the plurality of cores should have the same service processing function requiring load balancing; in the service process, each core corresponding to the same service processing function outputs an idle state signal if the core is idle, and outputs a busy state signal if the core is executing the service processing function;

if the message distribution unit determines that the first executed service processing function is the specified service processing function requiring load balancing, that is, the service processing function can be executed by a plurality of cores including core 0, the message distribution unit may detect status signals output by all cores corresponding to the service processing function, and send a message to core 0 when the status signal output by core 0 is idle;
and the virtual ethernet interface module is configured to, when an address of a core encapsulated in a packet corresponds to multiple cores, first detect status signals output by all cores corresponding to the address, and then send the packet to a core whose status signal is idle.
FIG. 6 is a diagram of a fourth preferred structure of a multicore processor device in one embodiment of the present invention. Referring to fig. 6, the multi-core processor device may also further include, on the basis of the structure shown in fig. 4, a plurality of virtual ethernet interface modules connected between every two cores that need to exchange packets, for example, the virtual ethernet interface module 1 may be set between the core 0 and the core 1 if the core 1 needs to perform antivirus processing after the core 0 performs firewall processing, and the virtual ethernet interface module n may be set between the core n-1 and the core n if the core n needs to perform service processing after the core n-1 performs service processing,
thus, the specific implementation of the above steps 307 and 308 by using the structure shown in fig. 6 includes:
the message distribution unit receives a message sent from the outside on an external physical interface and sends the message to a core 0 corresponding to the first executed service processing function;
the core 0 performs corresponding service processing such as firewall processing on the message, and the core 0 sends the message to the core 1 through the virtual Ethernet interface module 1;
if the core 1 is not the last core for executing the service processing function, the core 1 performs processing similar to that of the core 0, that is, performs corresponding service processing on the received message, such as antivirus processing, and then directly sends the message to the next core through a virtual ethernet interface module between the next core and the next core, and so on until the message is sent to the last core n;
and the n cores n perform corresponding service processing on the received message according to the loaded service processing function, and then send the message to the outside of the multi-core processor equipment through a physical interface which is pre-allocated to the n cores n.
It should be noted that, when configuring a corresponding core for each service processing function, preferably, the configuration management unit in the multi-core processor device may configure a control core and one or more data processing cores for each service processing function, and when configuring a plurality of data processing cores for each service processing function, the plurality of data processing cores may perform various applications such as active/standby or load sharing.
With the structure shown in fig. 6, the present invention can achieve load balancing of a specified service processing function. In this case, in step 303, when configuring the corresponding core for the specified service processing function requiring load balancing, the configuration management unit needs to further configure a plurality of cores in the multi-core processor to perform the same service processing function requiring load balancing; in the service process, each core corresponding to the same service processing function outputs an idle state signal if the core is idle, and outputs a busy state signal if the core is executing the service processing function;
thus, in the above specific implementation process of implementing step 307 and step 308 by using the structure shown in fig. 6:
the message distribution unit is configured to, when it is determined that the first performed service processing function is the specified service processing function that needs load balancing, that is, the service processing function may be performed by a plurality of cores including core 0, then the message distribution unit may detect status signals output by all cores corresponding to the service processing function, and send a message to core 0 when the status signal output by core 0 is idle;
in the subsequent process, each core in the multi-core processor that completes the service processing function is used to detect the status signals output by all cores corresponding to the service processing function when the next executed service processing function is the specified service processing function that needs load balancing, and directly send the message to the core whose status signal is idle through the virtual ethernet interface module between the core whose status signal is idle and the core whose status signal is idle.
It should be further noted that, referring to fig. 2 to fig. 6, in the multi-core processor device provided by the present invention, the configuration management unit may be implemented by using one or more specified cores in the multi-core processor. For example, a core in the multi-core processor is specified to be reserved as a dedicated management configuration unit for completing management control functions of starting, terminating, resource allocation and the like of the device. As another example, it is specified that a core in a multi-core processor that performs one of the service processing functions is multiplexed, that is, the core not only performs its configured service processing function but also is further used as a management configuration unit.
In addition, referring to fig. 2 to fig. 6, in the multi-core processor device provided by the present invention, the message distribution unit may also be one or more designated cores in the multi-core processor. Similar to the implementation of the configuration management unit, the packet distribution unit may specify a reserved dedicated core in the multi-core processor to implement, or may specify to multiplex a core performing a service processing function, for example, if the core 0 is configured to perform firewall processing, the core 0 may be further configured to also serve as the packet distribution unit.
It should be further noted that, when both the management physical interface and the external physical interface in the multi-core processor device are ethernet interfaces, the management physical interface and the external physical interface may be multiplexed.
In short, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
