According to the technical scheme provided by the embodiment of the disclosure, the obtained network server address corresponding to the domain name information of the target request in the data request forwarded by the local DNS server and the scheduling parameter of the network server are sent to the local DNS server together, so that the local DNS server can schedule the received data request according to the scheduling parameter of the network server. According to the technical scheme, the scheduling based on the user at the local DNS server is realized by means of the sending of the network server scheduling parameters, so that the scheduling fineness of the CDN can be effectively enhanced, and the efficiency and quality of data request load scheduling are improved.

Fig. 1 shows a flowchart of a data request load scheduling method according to an embodiment of the present disclosure, as shown in fig. 1, the data request load scheduling method includes the following steps S101 to S103:

in step S101, receiving data requests sent by a local DNS server, where the number of the data requests is one or more, and the data requests carry domain name information of a target request;

in step S102, acquiring a network server address corresponding to the target request domain name information according to the data request;

in step S103, a scheduling parameter of the network server is obtained, and a feedback packet is generated based on the address of the network server and the scheduling parameter of the network server and sent to the local DNS server, so that the local DNS server schedules the data request according to the scheduling parameter of the network server.

As mentioned above, with the development of data technology, in order to enable a user to obtain data to be accessed more quickly and accurately, a CDN (Content Delivery Network) has come up, and in order to balance data traffic and load of CDN nodes, scheduling needs to be performed on the CDN. Currently, CDN scheduling is mainly based on DNS server data to achieve traffic load balancing, but since a data request of a user needs to be transmitted to an authoritative server through a Local DNS server, scheduling can only be performed based on a data request generated by the Local DNS server, and user-based scheduling cannot be achieved, so that the CDN scheduling lacks a certain fineness.

In view of the above problem, in this embodiment, a data request load scheduling method is provided, which sends an address of a network server, which corresponds to domain name information of a target request in a data request forwarded by a local DNS server, and a scheduling parameter of the network server to the local DNS server, so that the local DNS server can schedule the received data request according to the scheduling parameter of the network server. According to the technical scheme, the scheduling based on the user at the local DNS server is realized by means of the sending of the network server scheduling parameters, so that the scheduling fineness of the CDN can be effectively enhanced, and the efficiency and quality of data request load scheduling are improved.

In this embodiment, the data request load scheduling method is suitable for an authoritative DNS server or other servers that can communicate with a local DNS server and can acquire a network server address corresponding to a target request domain name. For convenience of description, the following explanation and explanation take the authoritative DNS server as an example.

In an embodiment of the present disclosure, the data request refers to a domain name data request that is sent by a data requestor in a Domain Name System (DNS), at least carries domain name information of a target request that the data requestor wants to access, and wants to acquire an address of a network server corresponding to the domain name information of the target request. The number of the data requests may be one or more. In an embodiment of the present disclosure, the network server address may be, for example, a network server IP address such as a content distribution network node IP address, and the server may include a physical server, or a virtual server based on a virtual machine, a container, or the like, and may further include a server cluster.

In an embodiment of the present disclosure, the data requestor may also be called a domain name data requestor, which refers to a party that issues the domain name data request, for example, the data requestor may be a computer, a handheld device such as a mobile phone, or another device that can issue the domain name data request.

In an embodiment of the present disclosure, the local DNS server is used in a domain name system to communicate with the domain name data requester, receive a domain name data request sent by the domain name data requester, communicate with a higher level DNS server, that is, an authorized authoritative DNS server, and forward the domain name data request sent by the domain name data requester to a server of the authoritative DNS server, where the domain name data request at least carries a domain name information domain name data request of a target request that the domain name data requester wants to access.

In an embodiment of the present disclosure, the authoritative DNS server refers to an authorized DNS server in a domain name system, which is used for communicating with the local DNS server, and processes a domain name data request sent by the local DNS server, converts the domain name data request into a network server address corresponding to the target request domain name information, returns the network server address obtained by the conversion to the local DNS server, and returns the network server address obtained by the conversion to the domain name data requester through the local DNS server, so that the domain name data requester can directly access the network server corresponding to the IP address based on an HTTP protocol according to the received network server address to obtain the desired data. Since the authoritative DNS server is an authorized DNS server, the authoritative DNS server has stored or is capable of obtaining the mapping between different domain names and corresponding network server addresses, for example, by communicating with a network server.

In an embodiment of the present disclosure, the scheduling parameter is a load weight, and the load weight is used to indicate how many data connections the network server can bear, for example, if the load weight of the network server is 100, this means that the network server can bear at most 100 data connections and data transmissions, that is, can establish data connections and transmit data with at most 100 data requesters. In an embodiment of the present disclosure, the scheduling parameter of the network server may be stored in the authoritative DNS server in advance.

In an embodiment of the present disclosure, after obtaining a network server address corresponding to target request domain name information in a data request according to a received data request, a scheduling parameter of the network server may be obtained, and a feedback packet is generated and sent to the local DNS server according to a rule of a preset communication protocol based on the network server address and the scheduling parameter of the network server, so that the local DNS server schedules a data request of the data requester according to the scheduling parameter of the network server. The predefined communication protocol may be, for example, an EDNS (enhanced DNS) protocol, which may support the addition of extension fields, so that more useful information can be sent. Therefore, the local DNS server can realize smooth scheduling based on users, so that the scheduling fineness of a CDN (Content Delivery Network) can be effectively enhanced, and the system stability is enhanced.

In an embodiment of the present disclosure, the EDNS protocol can also increase the number of IP addresses that the authoritative DNS server can return at a single time by means of the custom coding scheme it supports. For example, in the prior art, due to the limitation of the size of the DNS packet, an authoritative DNS server can return only 16 IP addresses to the local DNS server at a time, whereas in the present embodiment, by means of a custom code that can be supported by the EDNS protocol, the number of IP addresses that the authoritative DNS server can return at a time is the number of network servers — the number of IP addresses corresponding to each network server, and assuming that the number of network servers is still 16 and the number of IP addresses corresponding to each network server is 2, the number of IP addresses that the authoritative DNS server can return at a time is 16 — 2 — 32.

In an embodiment of the present disclosure, the data request and the feedback packet are both sent based on a preset command, where the preset command may be a dig command, and the scheduling parameter can be carried in the feedback packet based on an EDNS protocol by using the dig command.

In an embodiment of the present disclosure, before the step of generating a feedback packet based on the address of the network server and the scheduling parameter of the network server and sending the feedback packet to the local DNS server in step S103, the method further includes:

determining the number of the obtained network server addresses;

In order to help the local DNS server to correctly resolve the feedback packet to obtain correct and all network server addresses and avoid situations such as loss of address information of the network server obtained by the resolving, loss of quantity, and the like, the authoritative DNS server determines the quantity of the network server addresses after obtaining the network server addresses corresponding to the domain name information of the target request in the data request, and generates the feedback packet together with the network server addresses and the scheduling parameters of the network server and sends the feedback packet to the local DNS server. The feedback message is obtained according to the specification of the preset communication protocol and has a preset message format.

Fig. 2 shows a flowchart of a data request load scheduling method according to another embodiment of the present disclosure, and as shown in fig. 2, the data request load scheduling method includes the following steps S201 to S203:

in step S201, receiving data requests sent by a data requester, where the number of the data requests is one or more, and the data requests carry domain name information of a target request;

in step S202, sending the data request to an authoritative DNS server based on a preset command, so that the authoritative DNS server obtains a network server address corresponding to the target request domain name information according to the data request;

in step S203, a feedback packet sent by the authoritative DNS server is received and analyzed, and the data request of the data requester is scheduled according to the feedback packet, where the feedback packet includes a network server address corresponding to the target request domain name information and a scheduling parameter of the network server.

As mentioned above, with the development of data technology, in order to enable a user to acquire data to be accessed more quickly and accurately, a CDN has come up with, and in order to balance data traffic and load of CDN nodes, scheduling needs to be performed for the CDN. Currently, CDN scheduling is mainly based on DNS server data to achieve traffic load balancing, but since a data request of a user needs to be transmitted to an authoritative server through a Local DNS server, scheduling can only be performed based on a data request generated by the Local DNS server, and user-based scheduling cannot be achieved, so that the CDN scheduling lacks a certain fineness.

In view of the above problem, in this embodiment, a data request load scheduling method is proposed, which schedules a data request according to a network server address received corresponding to target request domain name information in the data request sent by a data requester and a scheduling parameter of a network server. According to the technical scheme, the scheduling based on the user at the local DNS server is realized by means of the sending of the network server scheduling parameters, so that the scheduling fineness of the CDN can be effectively enhanced, and the efficiency and quality of data request load scheduling are improved.

In this embodiment, the data request load scheduling method is suitable for a local DNS server or other servers that can communicate with an authoritative DNS server to obtain, by means of the authoritative DNS server, a network server address corresponding to a target request domain name. For convenience of description, the local DNS server is explained and illustrated below as an example.

In the embodiment, the local DNS server forwards the received data request sent by the data requester to the authoritative DNS server, enabling the authoritative DNS server to obtain the network server address corresponding to the target request domain name information according to the data request, and sending a feedback message generated based on the address of the network server and the scheduling parameter of the network server to the local DNS server, the local DNS server receiving the feedback message and then analyzing the feedback message, and carries out scheduling and network server address allocation for the data request of the data requester according to the scheduling parameter of the network server and the network server address obtained by analysis, and the data request party can access the corresponding network server according to the distributed network server address based on the HTTP protocol to acquire the data required by the data request party.

In an embodiment of the present disclosure, the network server address may be a network server IP address such as a content distribution network node IP address, and the server may include a physical server, or a virtual server based on a virtual machine, a container, or the like, and may further include a server cluster.

In an embodiment of the present disclosure, the scheduling parameter is a load weight.

In this embodiment, the step of scheduling the data request of the data requester according to the feedback packet in step S203 may be implemented as:

In this embodiment, in order to perform accurate and refined scheduling on the data requester, first determining a first distribution network server that is first allocated to the data requester and a first scheduling parameter of the first distribution network server, then determining whether data connection of the first distribution network server reaches a full load, if not, allocating an address of the first distribution network server to the data requester until the first distribution network server reaches the full load, then determining a second distribution network server according to the above process, acquiring a second scheduling parameter of the second distribution network server, and allocating the address of the second distribution network server to the data requester according to the second scheduling parameter until the network server carried in the feedback message is allocated. In this way, by means of the load weight, a user-based fine and smooth scheduling of the data request load can be achieved, while also contributing to an enhanced system stability.

For example, if the feedback message includes two network servers, i.e., a network server a and a network server B, where the IP addresses of the network server a are IP _ a1 and IP _ a2, the load weight is 100, the IP addresses of the network server B are IP _ B1 and IP _ B2, and the load weight is 10, the local DNS server may allocate the IP addresses IP _ a1 and IP _ a2 of the network server a to the first 100 data requesters, and allocate the IP addresses IP _ B1 and IP _ B2 of the network server B to the subsequent data requesters, until the full load of the network server B is reached.

In an embodiment of the present disclosure, the allocation order of the network servers may be set according to the needs of practical applications, for example, the allocation order may be set as the generation order of the data requests, that is, the network servers are allocated according to the sequence of the data requests, and of course, other orders may also be adopted, which is not specifically limited by the present disclosure.

In an embodiment of the present disclosure, the feedback message further includes the number of the network server addresses.

Therefore, after receiving the feedback message sent by the authoritative DNS server, the local DNS server can extract the number of the network server addresses according to the regulation of a preset communication protocol and a preset message format, and further continuously analyze the feedback message according to the number of the network server addresses to finally obtain all the network server addresses and the scheduling parameters of the network server.

In an embodiment of the present disclosure, the method further includes:

In this embodiment, the local DNS server has a data caching capability and can cache the received data request and feedback packet, so that when a data request having the same destination request domain name information as the cached data request is received from the data requestor within the effective caching time of the data request and feedback packet, the network server address corresponding to the destination request domain name information of the cached data request can be directly sent to the data requestor without being requested from the authoritative DNS server.
