According to the embodiment of the invention, a distributed processing system and a method based on tag addressing calculation are provided.
Referring now to the drawings and the detailed description of the present invention, as shown in fig. 1-7, a distributed processing system based on tag addressing calculation according to an embodiment of the present invention separates the system processing logic from the specific functional entity, and places the system processing logic in the tag generation system for controlling and arranging; the system comprises a label registration center, a label generation center and a label routing center;
a label registration center: the functional body is provided to the system through a registration center, and a label code which can only correspond to the functional body is generated, so that the label generating system can sense the available label and the label functional body;
and a label generation center: when the system receives the data to be processed, firstly, a tag generation system adds a tag carrying sequence, or called a tag path, to the data to be processed according to a specific service strategy, and the data to be processed carries the tag path and then is transferred to a tag routing center;
label routing center: and entering the corresponding label function body for calculation processing according to the instruction of the label routing center, deleting the corresponding label from the label path after the current label function body is processed, and entering the next label function body for processing according to the instruction of the label routing center, so as to repeat the steps until all the labels are processed.
And dynamically changing a label path through a label generation system to realize the change of processing logic, and realizing the upgrading of functions by replacing the functional main body corresponding to the label. The existing label path can be dynamically edited and adjusted in the label function body processing process, and the dynamic change of the whole processing logic is realized.
A distributed processing system based on tag addressing computation is hereinafter referred to as a system.
In the system, the label generates a section of label code, called label for short, aiming at the functional body, and the corresponding functional body can be uniquely found through the label code. In the system, the tags and the tag function bodies form a pairing relation in a mode of registering the tags and the tag function bodies in the tag registration center, and can be sensed and called by the system.
As shown in fig. 2 (the sequence of label function body registration in the figure is 1. register function body; 2. allocate unique label code to form pairing relation; 3. synchronize pairing relation to generate forwarding route based on label; 4. sense available label function), the label registration center and the label generation center keep available label synchronization relation, and the label information changes and synchronizes to the label generation center in real time. In the system, the system function is increased by adding the label and the label function body. In the system, the label and the label function body are unavailable in a mode of canceling the label and the label function body. In the system, local function body upgrading is realized by modifying the function body corresponding to the label in the label registration center. As shown in fig. 3 (in the diagram, the local upgrade is realized by modifying the tag matching relationship, and the upgrade sequence is 1. register the function LabelA 1-function a; 2. re-register the function LabelA 1-function a'), the function upgrade is realized by matching new functions based on the original tag registration.
When the system receives the information data to be processed, firstly, the label generation center adds a sequence carrying labels, namely a label path, to the information data to be processed according to a specific service strategy.
The label generation center inputs information data payload to the label generation center according to the sequence of the label adding paths of 1; 2. label generation center output information data Label | Label 2| Label 3 payload
In the system, the label path is an ordered combination of a plurality of labels. Generation means, for example, a | C | D | B | F, a, C, D, B, F represents the corresponding tag code. In the system, the purpose of dynamically updating the processing logic can be realized by modifying the carried label path while processing the information data in the label function body. The generation indicates, for example, that the tag path a | B | C | D is edited into a | C | D | B | F, the execution sequence is adjusted by modifying the tag path, and the tag functionality F is added. In the system, the processing logic of the currently processed data is determined by a tag generation system. Different data may generate different label paths. The generation means, for example, that if the access data is from an external terminal, the label path a | B | C | D is generated, and the access data is from an internal network, the label path a | C | D | B | F is generated.
In the system, the label generated in the label registration center is synchronized to the label routing center through the pairing relation between the label and the functional body, and the forwarding route based on the label is generated in the label routing center. In the system, as shown in fig. 4 (in the diagram, an example of the LAbel-based forwarding route, for example, a LAbel-based forwarding route table is LAbel 1: funA: 1.1.1:81 LAbel 2: funB: 1.1.1:90 LAbel 3: funC: 2.2.2.2:80, the address of the functional body a is 1.1.1.1:81, the address of the functional body B is 1.1.1.1:90, and the address of the functional body C is 2.2.2.2: 80), a LAbel-based forwarding route is formed in the center of the LAbel route, and distributed computation processing based on LAbel addressing is realized. When the address of the label function changes, new data is automatically synchronized to the label routing center through the label registration center, as shown in fig. 5 (in the diagram, the label routing update sequence is 1. the address changes; 2. the label and function matching information is updated; 3. the label and function matching information is synchronized, and the label-based forwarding route is regenerated).
In the system, information data is routed to a designated label function body for processing, namely, a corresponding label is popped from a label path, and the completion of the processing of the last label in the label path indicates the completion of the processing of the whole function. The generation indicates, for example, a label path A | C | D | B | F, and the label path changes to A | C | D | B | F, C | D | B | F, D | B | F, B | F, F after being sequentially processed. In the system, in the label function body, the way of the label path can be modified, and the main body processing logic can be dynamically adjusted. The generation represents, for example, a labeled path a | C | D, and the modified labeled path becomes a | D | C. The tag function body inserts the available tag into the tag path to realize the processing of adding the corresponding function body. The generation represents, for example, a labeled path a | C | D, modified to become a | D | C | E. And the label function body deletes the appointed label in the label path to realize the processing of removing the corresponding function body. The generation represents, for example, a labeled path a | C | D, which becomes a | C upon modification of the labeled path.
The label and the label function body can provide a backup label and the label function body, and the function hot standby is carried out when the current label function body breaks down in operation. As shown in fig. 6 (which is a block diagram of an example with a backup tag and a tag function, when the LabelA 1-function a is registered and the LabelA 2-function a is registered, the routing table corresponding to the tag routing center is LabelA1: funA: 1.1.1:81 LabelA2: funA: 1.1.1:90 LabelA1: LabelA 2), the backup tag LabelA1: LabelA2 is configured, and when the LabelA1 corresponding to the routing fails or the corresponding function fails, the tag routing center automatically finds the function corresponding to the LabelA2 to replace the execution.
The label generation system comprises a manual configuration mode and a program dynamic analysis mode. The label path is carried and carried, including embedding into communication protocol fields, as well as embedding into communication payload data.
The tag path may limit the maximum depth, and for tag paths that have reached the maximum number of tags, modification is prohibited. A generation means, for example, that a maximum of 32 layers of the label path are defined, and processing is not continued beyond 32 layers. The label routing center can perform label path circulation detection, corresponds to an infinite reciprocating path, and pops up all labels after reaching a maximum depth threshold value. For example, the label path a is represented, and the label function body a inserts the label a in the processing, so that the system loops the processing, and after reaching the maximum depth 32, pops up all the labels, and ends the current processing flow.
Through a distributed architecture system based on label addressing, very flexible deployment, upgrading, hot standby and extensible capabilities can be achieved.
In one embodiment, as shown in FIG. 7, FIG. 7 is a block diagram of a complete example of tag addressing based computation, the example sequence being 1. implementation functionality is made available in the system by registering with a standard registry; 2. the information data to be processed enters a system, and a sequence carrying a label, namely a label path, is added to the information data to be processed according to a specific service strategy, such as the data to be processed + label A | label C | label B; 3. the label routing center transfers the information data to be processed to a designated functional body for processing according to the label path, and removes a top label LABElA to become the data to be processed + LaBEl C | LaBEl B; 4. the dynamic update of the processing function is realized by modifying the label, inserting the label, deleting the label or replacing the label. The label function body A processes the data to be processed plus label C | label B, after the function is processed, the next processing is continued according to the label routing center indication and the label path, the top label C is removed to become the data to be processed plus label B, the label function body B processes the data to be processed, the next label is found to be absent after the processing, the whole processing flow is ended, the label function body C processes the data to be processed plus label B, and the like.
According to another aspect of the present invention, there is provided a distributed processing method based on tag addressing calculation, as shown in fig. 8, the method including:
the tag functionality registers with the tag registry. (Label function registers in the label registration center, and the display of the label and the label function is available)
And the label generator generates a label path and synchronizes the label matching and the functional body matching information to the label routing center and the label generation center. (establishing applicable label paths based on currently processed data)
The label routing center forwards the label to the designated function according to the label path and pops up the top label. (for the label according to the top of the label path, inquiring the corresponding label function body, and popping up the label, when all labels in the label path are popped up, the system processing is completely finished)
The label function body executes specific functions, processes the next hop label according to the label routing center according to the label path indication, and sequentially reciprocates. (tag execution body operation processing concrete function, and processing next hop tag according to tag route instruction from tag routing center)
The label function body can edit and modify the label path, including label insertion, label deletion and label replacement, so as to achieve the change of the processing function. (besides the label path first given by the label generation center, the label functional body can also modify the existing label path in the running process to achieve the function of dynamically changing the processing flow)
