Traffic processing method, management platform, device, equipment and computer program product

Abstract

The application provides a traffic processing method, a management platform, an apparatus, a device and a computer program product; the method is applied to a cache layer in the management platform; the method comprises the following steps: in the case that a main cache network element of the cache layer receives a traffic request sent by a fast switching network element and does not query first session information which has been cached according to the traffic request, the traffic request is forwarded to a main slow switching network element, so that the main slow switching network element creates second session information according to the traffic request, and the second session information is sent to a standby cache network element of the cache layer through a standby slow switching network element; in the case that the standby cache network element of the cache layer receives the second session information, the second session information is forwarded to the main cache network element, so that the main cache network element sends the second session information to the fast switching network element. The request pressure of the slow switching layer can be reduced, and dynamic expansion and contraction can be realized.

Claims

1. A flow processing method, characterized in that, The method is applied to a caching layer in a management platform; the method includes: When the primary cache network element in the caching layer receives a traffic request from the fast forwarding network element and fails to find cached first session information based on the traffic request, it forwards the traffic request to the primary slow forwarding network element. The primary slow forwarding network element then creates second session information based on the traffic request and sends the second session information to the backup cache network element in the caching layer via the backup slow forwarding network element. The fast forwarding network element is a network element in the management layer of the management platform; the primary slow forwarding network element and the backup slow forwarding network element are network elements in the slow forwarding layer of the management platform. When the backup cache network element in the cache layer receives the second session information, it forwards the second session information to the main cache network element, so that the main cache network element sends the second session information to the fast forwarding network element.

2. The method according to claim 1, characterized in that, The step of forwarding the traffic request to the primary slow-transfer network element includes: Extract the quintuple information from the traffic request and determine the first hash value corresponding to the quintuple; Obtain the first quantity information corresponding to all cache network elements of the cache layer; and obtain the identification information corresponding to the management platform; The primary slow-transfer network element is determined based on the remainder information between the first hash value and the first quantity information, and / or the identification information, and the traffic request is forwarded to the primary slow-transfer network element.

3. The method according to claim 1, characterized in that, The method further includes: If the primary cache network element malfunctions and the backup cache network element receives a traffic request from the fast forwarding network element but fails to find the cached first session information based on the traffic request, the traffic request is forwarded to the primary slow forwarding network element so that the primary slow forwarding network element can create second session information based on the traffic request and send the second session information to the backup cache network element. Upon receiving the second session information, the backup cache network element sends the second session information to the fast forwarding network element.

4. The method according to claim 1, characterized in that, The main cache network element extracts the five-tuple information from the traffic request for the fast forwarding network element, determines the first hash value corresponding to the five-tuple, and obtains it based on the remainder information between the first hash value and the first quantity information corresponding to all cache network elements of the cache layer; The backup cache network element is the adjacent cache network element of the main cache network element.

5. The method according to claim 1, characterized in that, The statement that the cached first session information was not found based on the traffic request includes: Extract the 5-tuple information from the traffic request; the first session information was not found based on the 5-tuple information.

6. The method according to claim 1, characterized in that, The method further includes: When the main cache network element receives the traffic request sent by the fast forwarding network element and finds the first session information based on the traffic request, it sends the first session information to the fast forwarding network element.

7. A management platform, characterized in that, The management platform includes a fast transfer layer, a cache layer, and a slow transfer layer; the cache layer is located between the fast transfer layer and the slow transfer layer. The fast forwarding layer is used to send the received traffic requests to the main cache network element in the cache layer; The caching layer is used to forward the traffic request to the main slow-forwarding network element in the slow-forwarding layer when the main caching network element receives the traffic request sent by the fast-forwarding network element and no cached first session information is found according to the traffic request. The slow-transfer layer is used to create second session information according to the traffic request when the main slow-transfer network element receives the traffic request forwarded by the main cache network element, and send the second session information to the backup cache network element of the cache layer through the backup slow-transfer network element. The caching layer is further configured to forward the second session information to the main caching network element when the backup caching network element receives the second session information, so that the main caching network element sends the second session information to the fast forwarding network element.

8. A flow processing device, characterized in that, The caching layer used in the management platform includes: The first forwarding unit is configured to forward the traffic request to the primary slow forwarding network element when the primary cache network element in the cache layer receives a traffic request sent by the fast forwarding network element and fails to find cached first session information according to the traffic request. This allows the primary slow forwarding network element to create second session information based on the traffic request and send the second session information to the backup cache network element in the cache layer via the backup slow forwarding network element. The fast forwarding network element is a network element in the management layer of the management platform; the primary slow forwarding network element and the backup slow forwarding network element are network elements in the slow forwarding layer of the management platform. The second forwarding unit is used to forward the second session information to the main cache network element when the backup cache network element of the cache layer receives the second session information, so that the main cache network element sends the second session information to the fast forwarding network element.

9. An electronic device, characterized in that, The electronic device includes: Memory is used to store executable instructions or computer programs. A processor, when executing computer-executable instructions or computer programs stored in the memory, implements the method according to any one of claims 1 to 7.

10. A computer program product comprising a computer program or computer-executable instructions, characterized in that, When the computer program or computer-executable instructions are executed by a processor, they implement the method described in any one of claims 1 to 7.
