[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Reference Figure 1 , showing a step flow chart of a request processing method provided in an embodiment of the present invention, which is applied to a direct-connected server, wherein the direct-connected server is deployed in a content distribution network, and the content distribution network also includes at least one back-end real server that is communicatively connected to the direct-connected server.

[0058] In the embodiment of the present invention, the content distribution network may include a direct server (Director Server, DS) and a backend real server (real server, RS).

[0059] The directly connected server may be a server that directly provides services to users, and may be provided with a load balancing plug-in. When receiving a resource access request sent by a user, the load balancing plug-in may be used to allocate a suitable backend real server to the user.

[0060] The backend real server can be a physical server that stores and provides service-related data, which can be located in the data center of the content distribution network. Users cannot access it directly, but need to forward the request to the backend real server through the direct connection server for processing.

[0061] The method may specifically include the following steps:

[0062] Step 101, obtaining a resource access request;

[0063] A user can access a content distribution network through a client to obtain the resources he needs, thereby the user can generate a resource access request through the client and send it to the real server. The resource access request can be used to obtain the resources the user needs from the content distribution network.

[0064] In a specific implementation, the client can send a resource access request to a virtual server network address (Virtual IP Address, VIP) corresponding to the content distribution network to access a direct server (Director Server, DS), thereby completing the sending of the resource access request.

[0065] Step 102, detecting whether the resource access request records a backend real server corresponding to the resource access request;

[0066] In the embodiment of the present invention, in some special scenarios, the user may know the backend real server where the resource he needs is located. In this case, the direct connection server does not need to analyze the resource access request, but can directly determine the backend real server to which the resource access request needs to be forwarded.

[0067] In the case where the user is already aware of the backend real server where the resource he needs is located, he can directly write information related to the backend real server corresponding to the resource access request into the resource access request.

[0068] Therefore, for a directly connected server, before analyzing a resource access request, it can first detect whether the resource access request records the backend real server corresponding to the resource access request to determine whether the resource access request knows the backend real server and whether the resource access request needs to be analyzed.

[0069] Step 103: If the resource access request records the backend real server corresponding to the resource access request, forward the resource access request to the backend real server corresponding to the resource access request.

[0070] In the case where the backend real server corresponding to the resource access request is recorded in the resource access request, it can be considered that the resource access request is from the backend real server where the resource is known. In this case, there is no need to analyze the resource access request, but the resource access request can be directly forwarded to the backend real server corresponding to the resource access request, thereby reducing the time required for the direct-connected server to analyze the resource access request and improving the processing efficiency of the resource access request. At the same time, for the direct-connected server, the burden of analyzing the resource access request can also be reduced to a certain extent.

[0071] Through the request processing method provided by the embodiment of the present invention, a resource access request is obtained; it is detected whether the resource access request records the backend real server corresponding to the resource access request; if the resource access request records the backend real server corresponding to the resource access request, the resource access request is forwarded to the backend real server corresponding to the resource access request. Therefore, for some resource access requests, it is not necessary to search for a suitable backend real server through a directly connected server, but the corresponding backend real server can be directly determined, and the resource access request can be directly forwarded to the backend real server, which effectively improves the processing efficiency of resource access requests.

[0072] In an embodiment of the present invention, the step of detecting whether the resource access request records the backend real server corresponding to the resource access request includes:

[0073] S11, detecting whether the resource access request contains server identification information corresponding to the backend real server;

[0074] In a specific implementation, server identification information can be set for the backend real servers in advance to mark the backend real servers. The client can obtain the server identification information corresponding to the backend real servers in advance, and when the backend real server corresponding to the resource access request is determined, the server identification information can be written into the resource access request. At the same time, it can also avoid the direct retention of the access address of the backend real server, which affects the security of the content distribution network.

[0075] Specifically, the resource access request may be information based on TCP (Transmission Control Protocol). The TCP header may be provided with an optional field, and the server identification information may be written into the optional field of the TCP header.

[0076] Thereafter, the direct connection server may detect whether the resource access request contains server identification information corresponding to the backend real server, so as to determine whether the resource access request needs to be analyzed.

[0077] S12: If the resource access request records server identification information corresponding to the backend real server, determine that the resource access request records the backend real server corresponding to the resource access request.

[0078] If the resource access request records the server identification information corresponding to the backend real server, then it can be considered that the resource access request is the backend real server where the known resource is located. In this case, there is no need to analyze the resource access request, but the backend real server corresponding to the resource access request recorded in the resource access request can be determined directly based on the server identification information corresponding to the backend real server.

[0079] In an embodiment of the present invention, if the resource access request records the backend real server corresponding to the resource access request, the step of forwarding the resource access request to the backend real server corresponding to the resource access request includes:

[0080] S21, if the resource access request records the backend real server corresponding to the resource access request, determine the access address of the backend real server according to a preset backend real server mapping table and the server identification information corresponding to the backend real server;

[0081] Specifically, a backend real server mapping table may be stored in the direct connection server, in which the server identification information corresponding to the backend real server and the association relationship between the access address may be recorded. Therefore, when the backend real server corresponding to the resource access request is recorded in the resource access request, and the backend real server where the resource is located is determined, the access address of the backend real server can be found according to the backend real server mapping table and the server identification information corresponding to the backend real server recorded in the resource access request.

[0082] S22: Use the access address of the backend real server to forward the resource access request to the backend real server corresponding to the resource access request.

[0083] Thereafter, the access address of the backend real server may be used, and the directly connected server may directly forward the resource access request to the access address, thereby forwarding the resource access request to its corresponding backend real server.

[0084] In one embodiment of the present invention, the method further comprises:

[0085] S31, regularly obtaining the operation information of the backend real server in the content distribution network through a preset client.

[0086] In an embodiment of the present invention, in order to directly determine the backend real server corresponding to the resource access request, thereby reducing the time spent by the direct-connected server to analyze the resource access request and improving the processing efficiency of the resource access request, a preset period can be used to obtain the operating information of the backend real server in the content distribution network.

[0087] The operation information may include server identification information corresponding to the backend real server and the resource storage logic of the backend real server. The server identification information may be used to directly write the server identification information into the resource access request when the backend real server is determined, so that the directly connected server can identify the backend real server to which the resource access request needs to be forwarded. The resource storage logic of the backend real server may be a logical way for the content distribution network to allocate resource storage. When the resources to be obtained are known, it may be determined on which backend real servers the content distribution network stores the resources based on the resource storage logic.

[0088] In an embodiment of the present invention, before the step of obtaining a resource access request, the method further includes:

[0089] S41, determining, by the client based on the resource storage logic of the backend real server, the backend real server corresponding to the resource access request, and writing the server identification information of the backend real server corresponding to the resource access request into the server access request.

[0090] In a specific implementation, when a client needs to obtain resources through a content distribution network, the client can first determine, based on the resource storage logic of the acquired backend real server, on which backend real servers in the content distribution network the resources currently required by the client are currently stored. Thus, the client can directly determine the backend real server it needs to access, and directly write the server identification information of the backend real server in the resource access request.

[0091] In one embodiment of the present invention, the method further comprises:

[0092] S51, if the backend real server corresponding to the resource access request is inaccessible, deleting information associated with the backend real server in a preset backend real server mapping table;

[0093] Specifically, if the backend real server corresponding to the resource access request is inaccessible, it can be considered that the backend real server has failed or the response has timed out. In order to avoid the direct connection server repeatedly attempting to forward the resource access request to the abnormal backend real server, resulting in the client being unable to obtain data normally, the information associated with the backend real server can be deleted from the backend real server mapping table.

[0094] In this case, if the directly connected server receives a resource access request, and the resource access request records the server identification information corresponding to the abnormal backend real server, at this time, since the access address of the backend real server corresponding to the server identification information is not found in the backend real server mapping table, the directly connected server can consider that the server identification information corresponding to the backend real server recorded in the resource access request is an error message, and ignore the server identification information.

[0095] In a specific implementation, the directly connected server can periodically send heartbeat detection packets to each backend real server to regularly detect whether the backend real server is operating normally. If a backend real server fails or responds in timeout, the information associated with the backend real server can be deleted from the backend real server mapping table.

[0096] S52, calling the load balancing plug-in in the directly connected server to re-determine the backend real server corresponding to the resource access request.

[0097] After the direct-connection server ignores the server identification information recorded in the resource access request, the direct-connection server can call its preset load balancing plug-in and re-determine the back-end real server that can provide the corresponding resource for the resource access request based on the load balancing scheduling algorithm.

[0098] In one embodiment of the present invention, the method further comprises:

[0099] S61, if the resource access request does not record the backend real server corresponding to the resource access request, call the load balancing plug-in in the directly connected server to determine the backend real server corresponding to the resource access request.

[0100] Specifically, if the resource access request does not record the backend real server corresponding to the resource access request, then it can be considered that the resource access request has not determined the backend real server where the required resources are located. In this case, the direct connection server can call its preset load balancing plug-in to find the backend real server that can provide corresponding resources for the resource access request for the client based on the load balancing scheduling algorithm.

[0101] As a specific example of the present invention, Figure 2 1 is a flowchart of a request processing method provided in an embodiment of the present invention. The method comprises:

[0102] Step 1: Backend real server mapping table configuration, that is, the configuration of the hash table on the load balancing server.

[0103] The administrator of the directly connected server pre-configures the backend real server mapping table through a configuration interface (such as a command line, a Web interface, or an API) to map the identification information (such as an ID, a name) of the backend real server to its real access address (IP address and port number).

[0104] Step 2: Generate client request.

[0105] The client application adds detection logic to regularly obtain the backend real server information of the server cluster, including the backend real server identification information, content distribution network resource storage logic, etc. The client kernel adds a system call to support setting the backend real server identification information on the socket. After setting the backend real server identification information, the backend real server identification information will be added to the tcp header optional field when sending a tcp connection. When the client application sends a request, it first simulates the backend real server storage logic to calculate which backend real server the resource will be stored on. Then the corresponding backend real server identification information is generated, and the backend real server identification information is recorded on the socket through the kernel's new system call. The client application calls the tcp connection system call. Since the backend real server identification information is set for the corresponding socket, the kernel will mark the backend real server identification information RS-C when sending the corresponding resource access request in the form of a tcp data packet.

[0106] Step 3: Request reception and analysis

[0107] The direct connection server adds a backend real server identification information parsing function, and adds a mapping relationship table between the backend real server identification information and the access address of the backend real server. The direct connection server receives a resource access request from a client, and parses the backend real server identification information in the resource access request.

[0108] The backend real server identification information in the resource access request is specified by the client according to business requirements and is used to instruct the direct connection server to which backend real server to forward the request.

[0109] Step 4: Backend real server scheduling

[0110] The directly connected server searches the backend real server mapping table for the corresponding access address, ie, the real IP address and port number, according to the backend real server identification information obtained by parsing.

[0111] If a matching backend real server is found, the direct-connection server forwards the request to the backend real server for processing; if no matching backend real server is found, the direct-connection server can process the request according to a preset default policy or error handling mechanism.

[0112] Step 5: Backend real server health detection and failover

[0113] The directly connected server periodically sends heartbeat detection packets to each backend real server to detect the health status of the backend real server.

[0114] If a backend real server fails or times out, the direct connection server removes it from the backend real server mapping table and forwards subsequent requests to other normal backend real servers.

[0115] The present invention realizes efficient, safe and reliable request scheduling in a content distribution network through a back-end real server mapping mechanism in a direct-connected server. Specifically, the technical solution has the following beneficial effects:

[0116] Efficiency: The fast lookup of the backend real server mapping table is achieved through efficient data structures such as hash tables, which improves the efficiency of request scheduling. By specifying the backend real server access, the traffic interaction between machines is reduced and the service performance is improved.

[0117] Security: The client or internal node only embeds the identifier of the backend real server in the request without directly exposing the real IP address of the backend real server, thus protecting the security of the backend real server.

[0118] Reliability: Directly connected servers support health detection and failover of backend real servers. When a backend real server fails, it can be automatically removed from the backend real server mapping table to ensure service continuity and stability.

[0119] Intelligence: Through dynamic load balancing strategies, directly connected servers can be intelligently scheduled according to the real-time load conditions of the backend real servers and the characteristics of the requests, achieving efficient use of resources and rapid response to requests.
