Background

The popularity of 5G networks has proliferated the network bandwidth demand of data centers, and in order to alleviate bandwidth pressure and improve user experience, enterprises often choose a Content Delivery Network (CDN) to accelerate data transmission.

The content distribution network adds a new network architecture in the existing internet to distribute the content of the website to the network edge nearest to the user, so that the user can obtain the required content nearby, and the response speed of the user for accessing the website is improved.

Detailed Description

The present application will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the application are shown. This application may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. The embodiments described above are intended to be a complete and complete disclosure of the disclosure, so as to more fully convey the scope of the disclosure to those skilled in the art.

In the present specification, words such as "comprise" and "comprising" mean that in addition to elements and steps directly and unequivocally stated in the specification and claims, the technical solutions of the present application do not exclude other elements and steps not directly or unequivocally stated.

Terms such as "first" and "second" do not denote an order of the elements in time, space, size, etc., but rather are used to distinguish one element from another.

In this specification, a router refers to a hardware device that connects two or more networks, acts as a gateway between the networks, and is a dedicated intelligent network device that reads the address in each packet and then decides how to transmit. In the following description, the terms "router" and "gateway device" may be used interchangeably unless otherwise specified.

In this specification, a blockchain refers to a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc., and may be understood as a decentralized database in nature, including generating data blocks using cryptography, where each data block includes information related to an application scenario, and may be used to verify the validity of the information and generate a next data block.

In some embodiments of the present application, a blockchain network is constructed with routers or gateway devices as nodes and the website access content is cached (e.g., in a mirror-image backup manner) using the nodes or router nodes (in this specification, the terms "node" and "router node" are used interchangeably unless otherwise specified); meanwhile, access data associated with the cached website access content is added to the data blocks of the respective blockchain nodes or to the blockchain network (in this specification, unless otherwise specified, the operation of adding the access data to the data blocks is equivalent to the operation of adding the access data to the blockchain network). When a node receives a website access request of a terminal device, whether the content of the website to be accessed is cached in a block chain network (namely whether a node caches the content of the website to be accessed) is judged based on access data or data blocks, and if the node exists, the access request is redirected to the corresponding node, so that CDN acceleration is realized. Optionally, if no such node exists, the access request is redirected to the public domain name resolution server. Due to traceability, openness, independence and security of the blockchain data, the CDN service based on the blockchain network has higher reliability and expansibility, and the charging mechanism is more transparent.

In some embodiments of the present application, optionally, when there are multiple nodes caching content of a website to be accessed, one node is selected from the multiple nodes based on one or more of the following items: selecting a node from among the following based on one or more of: i) the matching degree of the IP address of the node and the IP address of the terminal equipment; ii) a distance of a geographical location of a node from a geographical location of the terminal device; and iii) a version number of the content of the website to be accessed cached at the node. Illustratively, an IP address with a higher matching degree with the IP address of the terminal device may be used as the access address, or a node closer to the geographic location of the terminal device may be used as the redirected node, or a node or an address corresponding to the website content with a higher version number may be used as the redirected node or the access address. Alternatively, a composite score may be obtained by giving corresponding weighting factors to the degree of matching of IP addresses, the distance between geographical locations, and the version number of cache contents, and the higher of the composite scores is determined as a node or access address to be redirected.

In some embodiments of the present application, in order to enable the external device to access the website content cached by the node, a corresponding access address is configured as the access data. Alternatively, the router may automatically allocate a public network IP and a port of an external service to the cached content as an access address for IPv4 using the UPnp protocol, and the external device may directly access the cached content based on the access address. In order to solve the problem of lack of IPv4 address resources, the IPv6 protocol is popularized in many countries in the world at present. Alternatively, the access address assigned to the cache contents may be based on the IPv6 protocol, in which case the IP address and port number of the cache contents may be fixed. Alternatively, the access data may also contain the version number of the cached website content and the geographic location of the node.

In some embodiments of the present application, optionally, when a router public network IP address discovers a change (e.g., due to a device reboot, a DHCP lease expire, etc.), access data reflecting the change is added to the data blocks of the respective nodes.

In some embodiments of the present application, optionally, when a new node joins the blockchain network, the data blocks of the nodes in the blockchain network are updated.

The block chain network 10 shown in fig. 1 includes a plurality of nodes 101-110, which may be directly connected together or indirectly connected together through other nodes. It should be noted that the number of nodes shown here is merely exemplary and should not be construed as any limitation to the described embodiments.

Each of the nodes 101-110 in fig. 1 has a block function by which data for accessing website contents via the local node or access data can be added to a data block of the local node. On the other hand, each of the

nodes

101 and 110 further has a routing function, so that information such as access data transmitted by other nodes can be transmitted to more nodes to realize updating of the data blocks in the whole block chain network. A data block as described herein is a data structure for recording access data. Illustratively, each data block is composed of a block header and a block body, the block body records all access data in the block chain network in the previous period, and the function of the block chain is mainly realized by the block header.

In the embodiment shown in fig. 1, the nodes 101-110 are routers or gateway devices configured to store and forward packets between different networks (e.g., between a local area network and the internet). In network communication, the router has the functions of judging network addresses and selecting IP paths, a flexible link system can be constructed in a plurality of network environments, and various subnets are linked through different data packets and medium access modes.

Optionally, nodes 101-110 in fig. 1 are broadband routers. Illustratively, the broadband router may integrate functions of router, firewall, bandwidth control and management, etc., with fast forwarding capability. Most broadband operators bind the MAC address with the ID and IP address of the user so as to perform user internet authentication. The broadband router with the MAC address function can write the MAC address on the network card into the broadband router, and the server can obtain broadband access authentication through MAC address verification during access. Broadband routers typically provide NAT functionality to translate the IP address assigned to each end device within the lan to a legally registered actual IP address of the Internet, so that end devices on the intranet can communicate directly with other hosts on the Internet. When the home broadband router is adopted as a node of the block chain network, the cost can be reduced and the bandwidth utilization rate can be improved by sharing the home broadband. Furthermore, home broadband routers are typically the edge nodes closest to the user equipment and are therefore well suited for building content distribution networks.

The process flow shown in fig. 2 comprises the following steps:

step S201: a blockchain network is constructed that includes routers as nodes. For example, the constructed blockchain network may have the network structure and features shown in fig. 1, which are not described herein again.

The following steps S202-S204 may be performed in parallel after step S201.

Step S202: when an event triggering updating of a data block occurs, a data block update operation is performed in a blockchain network. The events triggering the update of the data block include, but are not limited to, the joining of a new node in the blockchain network, the change of the cache content at the node, the change of the address of the node, and the like. For the update operation, it will be further described with the aid of fig. 3.

Step S203: when an access request from a terminal device is received, a processing operation for the access request is performed in the blockchain network. The processing operation will be further described below with the aid of fig. 4.

Step S204: when receiving a query request from a terminal device, querying data blocks of the blockchain network for historical data of the mobile terminal accessing the Internet via the blockchain network. The operation of processing the query request is further described below with reference to fig. 5.

The process flow shown in fig. 3 includes the following steps:

step S301: when the content of website a is accessed via one of the nodes in the blockchain network (hereinafter node 108 is taken as an example), node 108 will cache the content of website a synchronously. Optionally, the contents of website a are stored at node 108 in a mirror backup.

Step S302: node 108 generates access data associated with the cached content. Optionally, the access data includes an access address configured for accessing the contents of website a cached on node 108. Illustratively, the access address may be an IP address and port number based on the Upnp protocol, or an IP address and port number based on the IPv6 protocol. Additionally optionally, the access data further includes a version number of the cached website content and a geographic location of the node 108.

Step S303: the node 108 writes the access data into the data blocks of the node and other nodes.

Step S304: when the access address configured for the cached content of website a changes at node 108, node 108 will generate corresponding access data.

Step S305: the node 108 adds the access data reflecting the change to the data blocks of the node and other nodes.

Step S306: when a new node (e.g., node 111) is added to the block chain network,

nodes

101 and 110 will update the respective data blocks.

Fig. 4 is a flow diagram of a method for processing an access request according to some further embodiments of the present application.

The process flow shown in fig. 4 includes the following steps:

step S401: one of the nodes (hereinafter, node 106) in the blockchain network receives an access request from the terminal device, where the access request includes an indication of the website a to be accessed.

Step S402: node 106 determines whether any node in the blockchain network caches the contents of site a based on the data blocks stored thereon. If the content of the website A is cached by the node, the step S403 is proceeded, otherwise, the step S404 is proceeded.

Step S403: the access address assigned for the content is returned to the terminal device or the access request is redirected to the corresponding node (e.g., node 108).

In this step, when there are multiple nodes caching the content of the website a to be accessed, as described above, the redirected node or the access address may be determined based on one or more of the following items: the matching degree with the IP address of the terminal equipment, the distance with the geographical position of the terminal equipment and the version number of the content of the website A.

Step S404: node 106 redirects the access request to the public domain name resolution server.

The process flow shown in fig. 5 includes the following steps:

step S501: one of the nodes of the blockchain network (hereinafter, node 106 is taken as an example) receives an inquiry request from the terminal device, where the inquiry request includes an identification ID of the terminal device.

Step S502: the node 106 queries the data chunks stored thereon for historical data for access to the internet via the blockchain network with the terminal device specified by the identification ID.

Step S503: the node 106 returns the query result to the mobile terminal.

In the embodiment shown in fig. 5, the mobile terminal may access the internet via a plurality of nodes in the blockchain network, or the mobile terminal does not access the internet via the node (e.g., node 106) that sent the query request, but since the data block of each node records all the history data of the terminal device accessing the internet via the blockchain network, the mobile terminal may still query the history of its access to the internet via the blockchain network through any one node.

FIG. 6 is a flow diagram of a method for implementing edge computing network acceleration according to further embodiments of the present application.

The method flow shown in fig. 6 is executed by the terminal device and includes the following steps:

step S601: an access request is sent to one of the nodes (e.g., node 106) of a blockchain network that includes a plurality of routers as nodes (which may have, for example, the network structure and characteristics shown in fig. 1), including an indication that website a is to be accessed.

Alternatively, the application of the terminal device may have built-in access policies that designate nodes in the blockchain network as nodes that are preferentially accessed when accessing the internet.

Step S602: and acquiring the content of the website to be accessed based on the access address returned by the node 106. In the example, assume that the contents of website A are cached on node 108, so the access address returned by node 106 will point to node 108. Alternatively, the access address may be an IP address and port number based on the Upnp protocol, or an IP address and port number based on the IPv6 protocol.

Step S603: an inquiry request is sent to one of the nodes (e.g., node 103) of the blockchain network, the inquiry request containing the identification ID of the terminal device. Based on the identification ID, the node 103 may query its stored data block for historical data of the terminal device accessing the internet via the blockchain network as specified by the identification ID.

Step S604: the query result or the history data of the terminal device accessing the internet is received from the node 103.

It should be noted that, in the embodiment shown in fig. 6, the order of the access request sending step and the query request sending step is merely illustrative and not restrictive. Alternatively, steps S603 and S604 may precede steps S601 and S602, or steps S601 and S602 and steps S603 and S604 may be performed in parallel.

Fig. 7 is a schematic block diagram of a typical terminal device. Referring to fig. 7, terminal device 70 comprises a communication unit 710, a memory 720 (e.g., non-volatile memory such as flash memory, ROM, hard drive, magnetic disk, optical disk), a processor 730, a computer program 740 stored on memory 720 and executable on processor 730.

The communication unit 710 serves as a communication interface configured to establish a communication connection between the terminal device and an external device or network (e.g., the block chain network and its nodes shown in fig. 1, etc.).
