Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to realize that a client is not limited by a scene when scheduling an edge node, and improve the universality of scheduling, embodiments of the present application provide a scheduling system, method, apparatus, device, and medium.
In the embodiment of the application, the scheduling system comprises a target scheduling center node server and a target edge node server. The target dispatching center node server is used for receiving an access request sent by a client; analyzing the access request, determining a target source IP of the client, and determining a target edge node server corresponding to the target source IP according to the stored corresponding relation between the source IP and the edge node server; the access request is encapsulated by adopting an IP tunnel technology, and the encapsulated access request is sent to the target edge node server; and the target edge node server is used for receiving the encapsulated access request and responding to the access request.
Example 1:
fig. 1 is a schematic structural diagram of a scheduling system according to an embodiment of the present application, where the scheduling system includes: a target dispatch center node server 101 and a target edge node server 102.
The target dispatching center node server 101 is used for receiving an access request sent by a client; analyzing the access request, determining a target source IP of the client, and determining a target edge node server 102 corresponding to the target source IP according to the corresponding relationship between the stored source IP and the edge node server; encapsulating the access request by adopting an IP tunnel technology, and sending the encapsulated access request to the target edge node server 102;
the target edge node server 102 is configured to receive the encapsulated access request, and respond to the access request.
In the embodiment of the present application, a scheduling method in the prior art mainly includes: DNS scheduling, http302 scheduling, and http DNS scheduling. For the DNS scheduling, in the scheduling process, the DNS cannot acquire a source IP of the client, so that city-level and district-level scheduling cannot be performed, and an extended DNS mechanism (EDNS) is also controlled by a LOCAL domain name system (LOCAL Content Delivery Network, LOCAL DNS) of each layer, so that the scheduling range and effect cannot be controlled when global scheduling is performed; for the http302 scheduling, as http jump and first packet delay functions are added in the scheduling process corresponding to the scheduling method, the performance and service quality of the http302 scheduling are too low for a client with high quality requirement, and in addition, when the http jump is performed, the IP of the client is exposed, and a Uniform Resource Locator (URL) needs to be modified, so that the jump process is easily hijacked, and meanwhile, the http302 scheduling does not support the http request; for the http DNS scheduling, a client needs to be configured, and an SDK is installed in the client, so that the application range of the http DNS scheduling is small. In summary, a scheduling method with high universality for all scenes is not available in the prior art.
Based on this, the embodiment of the present application provides a scheduling system, which at least includes a target scheduling center node server 101 and a target edge node server 102.
Specifically, in the embodiment of the present application, when a user has a requirement for accessing a network, an access request may be sent based on a client, where the access request may be an http request or an http request. If the access request is an http request, the access request uses a standard http protocol; if the access request is an https request, the access request uses a standard https protocol.
The target dispatch center node server 101 is a 4-layer efficient forwarding device, and includes a Network Interface Controller (NIC) and a data processing module. The NIC is configured to obtain the access request, and send the access request to the data processing module, so that the data processing module analyzes the access request, and determines a target source IP of the client carried by the access request. Wherein, the target source IP is the IP of LOCAL DNS of the client.
In this embodiment of the present application, a corresponding relationship between a source IP and an edge node server is stored in a target scheduling center node server 101, and after a target source IP carried in an access request is determined, the target scheduling center node server 101 determines, according to the stored corresponding relationship, a target edge node server 102 corresponding to the target source IP in the corresponding relationship, where the target edge node server 102 is an edge node server providing a service for a client sending the access request.
In the embodiment of the present application, the scheduling center node server and the edge node server are in a network segment spanning manner, so the target scheduling center node server 101 cannot directly send the access request of the client to the target edge node server 102, but needs to adopt an IP tunnel technology to forward data in the network segment spanning manner.
Specifically, in the embodiment of the present application, after the target scheduling center node server 101 determines the target edge node server 102, the IP tunneling technique is adopted to encapsulate the received access request, and send the encapsulated access request to the target edge node server 102. The target edge node server 102 responds to the encapsulated access request after receiving the access request.
In the embodiment of the present application, the target edge node server 102 that responds to the access request sent by the client is determined by the target scheduling center node server 101, and the client does not need to perform special processing, and is scheduled without any knowledge, so that the universality of the scheduling method and the use experience of the user are improved.
Example 2:
in this embodiment of the present application, the system includes a plurality of node servers of the scheduling center, and in order to determine the node server 101 of the target scheduling center and implement the access requirement of the client, on the basis of the foregoing embodiment, in this embodiment of the present application, the system further includes:
the client 103 is configured to send a DNS resolution request to a Global Load Balance (GSLB) Server 104;
the GSLB server 104 is configured to receive the DNS resolution request sent by the client 103; analyzing the DNS analysis request, and determining the target source IP of the client 103; determining the target dispatching center node server 101 corresponding to the target source IP of the client 103 according to the stored corresponding relation between the source IP and the dispatching center node server; and sending the target IP of the target dispatching center node server 101 to the client.
In the embodiment of the present application, the scheduling system further includes a GSLB server 104, where the GSLB server 104 stores an IP of each scheduling center node server and a scheduling policy configured in advance by the scheduling configuration system. The scheduling strategy is the corresponding relation between each source IP and the node server of the scheduling center. The corresponding relationship may be that one source IP corresponds to one node server of the scheduling center, or that a plurality of source IPs correspond to one node server of the scheduling center. In order to avoid the waste of resources, a plurality of source IPs generally correspond to one dispatch center node server.
In order to determine a target scheduling center node server 101 among a plurality of scheduling center node servers, when a client 103 has an access requirement, the client 103 sends a DNS resolution request to the GSLB server 104, and after receiving the DNS resolution request, the GSLB server 104 resolves the DNS resolution request to obtain a target source IP of the client 103, which is carried in the DNS resolution request. The GSLB server 104 searches for a scheduling center node server corresponding to the target source IP in the correspondence according to a correspondence between the source IP and the scheduling center node server stored in advance, and determines the scheduling center node server as the target scheduling center node server 101 corresponding to the client 103. The GSLB server 104 obtains the stored target IP of the target dispatch center node server 101 and sends the target IP to the client 103. The client 103 may send an access request to the target dispatch center node server 101 based on the target IP of the target dispatch center node server 101.
Example 3:
in order to implement the scheduling of the client to the edge node server, on the basis of the foregoing embodiments, in this embodiment of the present application, the target scheduling center node server 101 is specifically configured to determine a target area position corresponding to a target source IP according to a pre-stored correspondence between the source IP and the area position; and determining an edge node server corresponding to the target area position according to a pre-stored corresponding relationship between the area position and the edge node server, and determining the edge node server as the target edge node server 102.
In the embodiment of the present application, the target scheduling center node server 101 stores a corresponding relationship between a source IP and an area location, which are configured in advance by a scheduling configuration system, and a corresponding relationship between an area location and an edge server. The corresponding relation between the source IP and the area position is stored in an IP library, and the corresponding relation between the area position and the edge server is stored in a forwarding strategy.
Specifically, in this embodiment of the present application, after receiving an access request sent by a client 103, a target scheduling center node server 101 obtains a source IP corresponding to the client 103 and carried in the access request, searches for a target area position corresponding to the source IP according to a stored correspondence between the source IP and the area position, and searches for a target edge node server 102 corresponding to the target area position in the stored correspondence between the area position and the edge node server.
In the embodiment of the present application, on the premise that the original access request flow of the client 103 is not changed, a scheduling center node server, that is, a 4-layer efficient forwarder setting, is added in the scheduling system, and is used to obtain the target source IP of the client 103. And according to the information pre-stored in the IP library, the location of the target area corresponding to the target source IP is determined, that is, the location information of the client 103 is determined. And determines the target edge node server 102 corresponding to the target area location according to a pre-stored forwarding policy. The forwarding of the access request is completed on the side of the target scheduling center node server 101, so that the client 103 does not have any perception and does not need any special processing, and the target edge node server 102 corresponding to the target area position where the client 103 is located provides service for the client 103.
Based on the above, the embodiment of the application is suitable for most clients based on the standard http protocol or the standard https protocol, realizes high-efficiency and low-cost access to the edge node server, and better realizes the sinking of the edge node server.
Fig. 2 is a schematic diagram of an IP library provided in an embodiment of the present application, and as shown in fig. 2, the IP library stores a corresponding relationship between a source IP and a location of an area. For example, when the source IP is 58.16.1.0/30, the corresponding regional position is prefecture A, and when the source IP is 58.16.1.5/30, the corresponding regional position is prefecture B.
Fig. 3 is a schematic diagram of a forwarding policy provided in an embodiment of the present application, and as shown in fig. 3, the forwarding policy stores a correspondence between an area location and an edge node server, and also stores an IP of the edge node server. For example, the edge node server corresponding to prefecture and county a is edge node server a, and the IP corresponding to the edge node server is IP 1; the edge node server corresponding to prefecture B is edge node server B, and the IP corresponding to the edge node server is IP 2.
Fig. 4 is a schematic diagram of a processing process of a target scheduling center node server for an access request according to an embodiment of the present application, where as shown in fig. 4, a forwarding configuration system issues a forwarding policy to the target scheduling center node server, and the target scheduling center node server receives and stores the forwarding policy. And the NIC of the target dispatching center node server receives the access request sent by the client, and the data processing module of the target dispatching center node server determines a target edge node server corresponding to the client according to the stored IP library and the forwarding strategy. And encapsulating the access request by adopting an IP tunnel technology, and sending the encapsulated access request to the target edge node server.
Example 4:
to implement forwarding of an access request, on the basis of the foregoing embodiments, in an embodiment of the present application, the target scheduling center node server 101 is specifically configured to write the access request into a preset position in an encapsulated IP packet by using an IP tunneling technique according to the pre-stored encapsulated IP packet.
In the embodiment of the present application, the scheduling center node server and the edge node server are in a network segment spanning manner, so the target scheduling center node server 101 cannot directly send the access request of the client 103 to the target edge node server 102, but needs to adopt an IP tunneling technique to forward data in the network segment spanning manner.
The IP tunneling technique encapsulates a complete IP packet into a data portion of another new IP packet, and transmits the data portion to a specified location through a router. The router does not care about the contents of the original protocol being encapsulated in this process. After reaching the device at the destination point, the device at the destination point opens the encapsulated IP message and obtains the original IP message by depending on the own computing capability and the support of the IP tunnel protocol.
Specifically, in the embodiment of the present application, the target scheduling center node server 101 is a tunnel start point of the IP tunnel, and the target edge node server 102 is a tunnel end point of the IP tunnel. The encapsulated IP packet is pre-stored in the target scheduling center node server 101, and before forwarding the access request sent by the client 103 to the target edge node server 102, the target scheduling center node server 101 needs to obtain the encapsulated IP packet, write the access request into a preset position in the encapsulated IP packet, and send the IP packet encapsulated with the access request to the target edge node server 102.
Fig. 5 is a schematic diagram of a process of forwarding data across network segments by using an IP tunneling technique according to an embodiment of the present application, where as shown in fig. 5, an access request carries a network layer header and network layer data, where the network layer header is a target source IP of a client, the network layer data includes a transport layer header and transport layer data, and the transport layer header is a Transmission Control Protocol (TCP). And the target dispatching center node server writes the access request into a preset position in the encapsulated IP message, wherein the preset position is a position used for storing network layer data in the encapsulated IP message. The network layer header of the encapsulated IP packet includes the version of the IP protocol, the IP of the start point of the IP tunnel, the IP of the end point of the IP tunnel, and the checksum. In fig. 5, the version of the IP protocol is the fourth version, the IP at the start of the IP tunnel is the target IP of the target dispatch center node server, and the IP at the end of the IP tunnel is the IP of the target edge node server.
Fig. 6 is an interaction process diagram of the scheduling system according to the embodiment of the present application, and as shown in fig. 6, a client sends a DNS resolution request to a GSLB server. After receiving the DNS analysis request, the GSLB server analyzes the DNS analysis request, determines a target source IP of the client, determines a target dispatching center node server corresponding to the target source IP according to the target source IP and a corresponding relation between the source IP and the dispatching center node server which is stored in advance, and sends the target IP of the target dispatching center node server to the client. And after receiving the target IP, the client sends an access request to a target dispatching center node server according to the target IP. After receiving the access request, the target dispatching center node server analyzes the access request, determines a target source IP of the client, and stores an edge node server corresponding to edge district 1 and an edge node server corresponding to edge district 2 in the target dispatching center node server, and if the target dispatching center node server determines that the target source IP corresponding to the client belongs to edge district 2, the edge node server corresponding to edge district 2 is determined to be the target edge node server corresponding to the target source IP; and encapsulating the access request by adopting an IP tunnel technology, and sending the encapsulated access request to the target edge node server.
