Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a management method of drainage information, which can be applied to a network framework shown in fig. 1. The network framework comprises a client, a drainage node and a summary node. The method comprises the steps that a drainage node is responsible for flow guiding of clients in a certain area, the clients in the same area are all connected with the drainage node responsible for the area, when an application program running on the client generates network browsing, flow will reach the drainage node first, and the drainage node can determine drainage information based on the flow, wherein the drainage information comprises an IP address of the client, a used port and application information of the application program.
Each drainage node can report the drainage information obtained by the drainage node to the summarizing node at regular time, and the summarizing node receives the drainage information reported by each drainage node and performs summarizing and sorting to obtain the global drainage information.
When the drainage node sends a drainage information request to the summary node, the summary node sends the summarized global drainage information to the drainage node, the drainage node can plan a routing path used by flow sent by each application program on a client according to the global drainage information, and the routing path is used dispersedly, so that optimal distribution can be carried out based on the existing network resources, and the network service quality of the application programs on each client can be effectively ensured.
Referring to fig. 2, a flowchart of a management method for drainage information according to an embodiment of the present invention is provided, where the method is applied to a summary node, that is, executed by the summary node, and the method specifically includes the following steps.
The IP address and the port included in the drainage information are the IP address and the port of the client, where the application information is the application category and the application identifier of the application program running on the client, for example, the application category is a game category, and the application identifier is an identifier of a specific game. The drainage information may also include a transport protocol such that the drainage node selects a corresponding link according to a particular transport protocol. The drainage nodes are distributed in all places, so the summary node can receive the drainage information reported by all the local nodes, and comprehensive summary and arrangement are performed.
Specifically, when receiving network traffic sent by a client in a region in charge, a drainage node performs matching based on local drainage information, and if the matching is successful, stores the drainage information record and prepares to upload; if the matching is unsuccessful, the network traffic can be further identified based on a traffic characteristic identification technology to obtain the application program sending the network traffic, and simultaneously, a source IP address, a port (namely a client IP and a port) and application program information and the like corresponding to the network traffic are stored to prepare for uploading.
When the application program information corresponding to the network flow is obtained by the drainage node, the routing path corresponding to the application program information can be determined based on a preset routing strategy, and forwarding is carried out. Therefore, aiming at the guidance of different application program flows, corresponding routing paths are configured for different application programs so as to ensure the reasonable configuration of resources.
When receiving the drainage information sent by the drainage node, the summary node may check the drainage information and the identity of the drainage node, for example, may verify the type and format of the drainage information, so as to ensure the integrity, validity, and correctness of the data.
The cache unit may use a non-relational database, such as a redis cache or a Memcached cache, etc. Both the redis cache and the Memcached cache belong to a key-value distributed storage system, and have the characteristics of high query speed, large data storage quantity and high support for concurrency.
The invention does not adopt the traditional data storage method, namely, the data storage is carried out by adopting a database (namely, a relational database), but the received drainage information is stored in the cache unit, thereby avoiding the problems of too low response speed, reduced system performance and the like caused by too much pressure of the connection number of the database when a plurality of drainage nodes request simultaneously. The embodiment of the invention adopts a cache mode, can store data in the memory so as to improve the data processing speed, and the data can be directly read and written by the application program without establishing connection, so that the embodiment of the invention has no limitation of the number of the connection and can support a scene of high concurrent requests.
The summary node can store the drainage information in a classified manner, and the specific process can be as follows: determining whether the first data set stored in the cache unit is in the drainage information or not; when the drainage information is stored in the first data set, storing the drainage information in a second data set in the cache unit; and when the drainage information is not stored in the first data set, storing the drainage information in a third data set in the cache unit. The flow guide information received by the summarizing node can be stored in the cache unit according to the process, and then the flow guide information in the second data set and the flow guide information in the third data set are sorted into the first data set according to a first preset period. The specific finishing process is as follows.
Because the drainage information in the second data set already exists in the first data set, when the drainage information in the second data set is sorted into the first data set according to the first preset period, the drainage information does not need to be written into the first data set again, but only the expiration time of the drainage information in the first data set needs to be updated, and the sorted drainage information in the second data set is deleted. When the drainage information in the third data set is sorted into the first data set according to a first preset period, the drainage information in the third data set is written into the first data set, the expiration time of the drainage information is set, and the sorted drainage information in the third data set is deleted. That is, if the drainage information is stored in the second data set in the cache unit, the expiration time of the drainage information in the first data set may be updated according to a first preset period. If the drainage information is stored in a third data set in the cache unit, the drainage information may be stored in the first data set according to a first preset period, an expiration time of the drainage information may be set, and the drainage information in the third data set may be deleted.
When sorting the drainage information in the second data set and the third data set, the second data set may be renamed to a fourth data set, the third data set may be renamed to a fifth data set, and the drainage information in the fourth data set and the fifth data set may be sorted into the first data set according to the sorting process. Meanwhile, an empty second data set and an empty third data set are newly built for storing the next received new drainage information, so that the accuracy of summarizing and sorting the drainage information can be guaranteed, and the accurate storage of the new drainage information can be guaranteed. Each data set in the embodiment of the present invention may adopt a storage manner of a hash table.
Each piece of drainage information is provided with expiration time, the expiration time of the drainage information is prolonged backwards when the drainage information is received again, and the drainage information is deleted when the expiration time of the drainage information expires. When the expiration time of the drainage information is determined, the current time can be prolonged backwards by a preset time to obtain the expiration time, and the reporting time of the drainage information can also be prolonged backwards by a preset time to obtain the expiration time. The reporting time of the drainage information can be the time when the drainage node confirms to obtain the drainage information based on the client flow, or the time when the drainage node reports the drainage information to the summary node.
The embodiment of the invention firstly classifies and stores the received new drainage information, then regularly carries out summarization by stages, and stores the new information which is different from the data set of the summarized information, so that the processing of the new information and the summarization of the information can be processed in parallel, thereby avoiding the situation that when the database is used for storing data, the new information is reported when the historical drainage information is summarized and collated, and the new information is not processed in time due to time consumption of the summarization and the collation, thereby causing the incomplete condition of the response information. The embodiment of the invention can ensure that newly reported drainage information is timely stored in the cache unit, thereby ensuring the integrity of the information in each response and effectively shortening the whole time consumption of new information processing and summarizing.
The drainage node can request the drainage information through a request interface provided by the summary node, and the request interface can simultaneously accept high concurrent requests.
And step 204, sending the global drainage information to the drainage node.
When request information sent by the drainage node is received, the drainage information contained in the first data set and the third data set can be obtained, and the drainage information in the first data set and the third data set is all the drainage information received by the summary node.
In this embodiment of the present invention, the summary node may further generate a backup file at regular time, that is, according to a second preset period, and store the backup file in the database, so as to facilitate error checking and manual verification, where the backup file includes the global drainage information in the cache unit, or in other words, the backup file includes the drainage information included in the first data set and the third data set.
