Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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.

Before describing the method for accessing internet sites in the internet of view according to the present application, the following description will first describe a manner for accessing internet sites in the internet of view in the related art. In the related art, the internet of view does not have a same-name website of the internet website deployed therein (for example, for a hundred-degree network, the hundred-degree network may be deployed in the internet or in the internet of view, and a service provided by the hundred-degree network in the internet for a user is the same as a service provided by the hundred-degree network in the internet for the user, so the hundred-degree network in the internet of view is a same-name website of the hundred-degree network in the internet of view), and therefore, the user can only access the internet website located in the internet through the terminal of the internet of view.

Based on the above problems, the present application proposes the following technical idea: the method comprises the following steps of erecting an internet website deployed in the internet into the video network, and providing an access method for the internet website located in the video network: when a user accesses a target website through a superior program (such as a browser), whether a homonymous website of the target website exists in a video network is judged preferentially, if so, an IP address of the homonymous website of the target website in the video network is returned to the superior program, so that the user accesses the homonymous website preferentially, and the speed of accessing the internet website in the video network through a video network terminal is higher and the security is higher, so that the speed of responding to a user request can be improved significantly by accessing the homonymous website preferentially; if the target website does not exist, the IP address of the target website in the Internet is returned to the upper-level program, so that the user can access the target website, and the user can be ensured to finally obtain the website service. Therefore, the method for accessing the internet website in the video network can flexibly switch the access mode of the internet website in the video network according to actual requirements, and improves the use experience of users.

FIG. 1 is a schematic diagram of an implementation environment shown in an embodiment of the present application. Referring to fig. 1, in the implementation environment, a browser and a video networking client (the video networking client is a client corresponding to a video networking domain name server) are installed on a video networking terminal, and are in communication connection with the video networking domain name server through the video networking client, the video networking domain name server is in communication connection with an internet domain name server through a data repeater of the video networking and the internet, an internet website a is deployed in the video networking, an internet website a ' is deployed in the internet, the internet website a is a same-name website of the internet website a ', and a service provided by the internet website a for a user is the same as a service provided by the internet website a ' for the user.

The embodiment of the application provides a method for accessing an internet website in a video network, which is applied to a video network client in fig. 1. Fig. 2 is a flowchart illustrating a first method for accessing an internet site according to an embodiment of the present application. Referring to fig. 2, the method for accessing internet sites in a video network provided by the present application includes the following steps:

step S11: and intercepting a DNS request sent by a superior program of the video networking terminal to an Internet domain name server, wherein the DNS request is generated when the superior program requests to access a target Internet website.

In the embodiment of the present application, the upper level program may be understood as the browser in fig. 1. In general, when a user accesses a target internet site through a superior program, the superior program generates a DNS request for an internet domain name server by default, sends the DNS request to the internet domain name server through a series of intermediate forwarding servers, obtains an IP address of the target internet site within the internet, and then accesses the target internet site deployed within the internet through the IP address.

In the embodiment of the application, after the superior program generates and sends the DNS request for the internet domain name server, the video networking client intercepts the DNS request and prevents the DNS request from being sent to the internet domain name server.

Step S12: and modifying the format of the DNS request according to the format of the video networking DNS request to obtain the video networking DNS request.

In the embodiment of the application, after intercepting a DNS request, a client side of the video network modifies the format of the DNS request into a DNS request in the video network format, and the DNS request in the video network format is used for sending to a video network domain name server.

Step S13: and sending the DNS request to a domain name server of the video network.

Step S14: and if a first IP address returned by the domain name server of the video network aiming at the DNS request of the video network is received, returning the first IP address to the superior program in a DNS response mode, so that the superior program accesses the target internet website deployed in the video network according to the first IP address.

In this embodiment of the application, the first IP address is an IP address of a target internet site deployed in the internet of view, and as described above, the target internet site deployed in the internet of view is a same-name site of the target internet site deployed in the internet of view.

After sending the DNS request of the video network to the domain name server of the video network, if the received response packet does not contain the first IP address, it indicates that the same-name website of the target internet website in the video network is not deployed in the video network, that is: the upper program cannot access the target internet website through the video networking approach. On the contrary, if the received response packet contains the first IP address, which indicates that the target internet site is deployed in the video network and is the same name site in the video network, the superior program can access the target internet site through the video network. After the video networking client acquires the first IP address, a DNS response packet is generated according to the first IP address, and the DNS response packet is sent to a superior program. After the DNS response packet is received, the superior program analyzes the DNS response packet to obtain a first IP address, and can access a target Internet website deployed in the video network through a video network according to the first IP address.

In the embodiment of the application, a video network client intercepts a DNS request packet sent by a superior program, the DNS request packet is modified into a DNS request packet in a video network format and sent to a video network domain name server, the video network domain name server inquires a first IP address of a target internet website deployed in the video network, and the first IP address is returned to the superior program through the video network client. According to the method and the device, when a user accesses a target website through a superior program, whether the same-name website of the target website exists in a video network is judged preferentially, if yes, an IP address of the same-name website of the target website in the video network is returned to the superior program, so that the user accesses the same-name website preferentially.

In the embodiment of the present application, if the first IP address is not queried by the domain name server of the video network, then: the method for accessing the target internet site deployed in the internet is provided to ensure that the upper-level program of the video network terminal can still access the target internet site at last, and is shown in fig. 3.

Fig. 3 is a flowchart illustrating a second method for accessing an internet site according to an embodiment of the present application. Referring to fig. 3, an embodiment of the present application may access a target internet site deployed in the internet by:

step S21: and if the first IP address returned by the video networking domain name server aiming at the video networking DNS request is not received, modifying the video networking DNS request into an Internet DNS request.

In the embodiment of the application, if the response packet received by the video network client does not contain the first IP address, the video network DNS request is modified into the Internet DNS request according to the format of the Internet DNS request. If the internet DNS request which is received before is also stored in the video network client, the internet DNS request can be directly read without modifying the video network DNS request into the internet DNS request.

Step S22: and sending the Internet DNS request to the video networking domain name server, wherein the video networking domain name server is used for forwarding the Internet DNS request to the Internet domain name server and receiving a second IP address of the target Internet website returned by the Internet domain name server, and the second IP address is different from the first IP address.

In the embodiment of the application, after modifying the video networking DNS request into the Internet DNS request, the video networking client sends the Internet DNS request to the video networking domain name server, the video networking domain name server sends the Internet DNS request to the Internet domain name server through a data repeater of the video networking and the Internet, the Internet domain name server obtains a second IP address of a target Internet website deployed in the Internet and returns the second IP address to the video networking domain name server, and the video networking domain name server sends the second IP address to the video networking client.

Step S23: and receiving a second IP address returned by the video networking domain name server aiming at the Internet DNS request, and returning the second IP address to the superior program in a DNS response mode so that the superior program can access the target Internet website deployed in the Internet according to the second IP address.

And the video networking client receives a second IP address returned by the video networking domain name server, generates a DNS response packet according to the second IP address, sends the DNS response packet to a superior program, and the superior program analyzes the DNS response packet to obtain the second IP address and can access a target Internet website deployed in the Internet according to the second IP address.

In the embodiment of the application, if the upper-level program cannot access the internet website deployed in the video network, the video network client sends the internet DNS request to the video network domain name server again, and the video network domain name server acquires the IP address of the target internet website deployed in the internet from the internet domain name server, so that the upper-level program can still obtain the target internet website.

In combination with the above embodiments, in an implementation manner, the format of the DNS request may be modified through the following steps, so as to obtain a video networking DNS request, as shown in fig. 4 in detail. Fig. 4 is a flow chart illustrating a method for modifying a format of a DNS request according to an embodiment of the present application. Referring to fig. 4, step S12 specifically includes:

step S121: and acquiring the domain name of the target internet website in the DNS request.

Step S122: if the format of the domain name is the Internet format, modifying the format of the domain name into a video networking format;

step S123: generating the DNS request of the video network according to the modified domain name of the video network format;

step S124: and if the format of the domain name is a video networking format, taking the DNS request as the video networking DNS request.

In the embodiment of the present application, the modification of the format of the domain name may be a modification of a suffix of the domain name. For example: the suffix of the format of the internet domain name is: ". COM", the format of the Internet of view domain name being suffixed by ". V", ". T", ". X", ". Y", etc. For ease of presentation of the various embodiments, the suffix to the format of the view network domain name of the present application is taken as ". V".

Exemplarily, taking the domain name of the target internet website in the DNS request as www.baidu.com, the format of the domain name is in an interconnected grid format, and the suffix ". COM" is modified into ". V", i.e. the domain name www.baidu.v in a view networking format is obtained. And after the WWW.BAIDU.V is obtained, regenerating a DNS request of the video network according to the domain name.

In this embodiment of the application, the superior program may also directly send a DNS request with a domain name format in the video networking format to the video networking client, and at this time, the video networking client resolves the domain name format in the DNS request to be the video networking format, and does not perform format conversion, and may directly use the DNS request as the video networking DNS request.

With reference to the foregoing embodiment, in an implementation manner, after receiving the first IP address sent by the video network client, the upper level program of the video network terminal may access the target internet site according to the first IP address. In the process, the video network client can be used for providing data transfer service between the upper-level program and the target internet website, and specifically comprises the following steps:

acquiring a video networking number corresponding to the first IP address;

In the embodiment of the application, after obtaining a first IP address, a superior program takes the first IP address as a destination address, encapsulates data to be sent into an internet data packet, and sends the internet data packet to a video network client; after receiving the internet data packet, the video network client analyzes the internet data packet to obtain a first IP address, and initiates a request for inquiring the video network number to a video network domain name server (a domain name-IP-video network number relation table is stored in the video network domain name server in advance, and the corresponding video network number can be inquired according to the first IP address sent by the video network client) so as to inquire the video network number corresponding to the first IP address; after receiving the video networking number, the video networking client takes the video networking number as a destination address, and encapsulates the original internet data packet into a video networking data packet again; and finally, the video networking client sends the video networking data packet obtained by encapsulation to a target internet website in the video networking through an autonomous server in the video networking. Meanwhile, the video network client can also receive a video network data packet returned by a target internet website in the video network through an autonomous server in the video network, decapsulate the video network data packet to obtain an internet data packet, and return the internet data packet to a superior program. In other words, the upper-level program and the target internet website in the video network can mutually transmit internet data through the video network transparent transmission function.

In the embodiment of the application, after the superior program obtains the first IP address, the internet data packet is transmitted to the target internet website through the transparent transmission function of the video network, so that the internet data is transmitted in the video network by using the video network communication technology, and the characteristics of safety and quickness based on the video network communication technology are realized, so that the communication efficiency between the superior program and the target internet website is improved, the speed of responding to the user to access the target internet website is improved, and the use experience of the user is improved.

The embodiment of the application also provides a method for accessing the internet website, which is applied to the video networking domain name server in fig. 1. Fig. 5 is a flowchart illustrating a third method for accessing an internet site according to an embodiment of the present application. Referring to fig. 5, a third method for accessing an internet site in the present application includes the steps of:

step S31: receiving a target DNS request sent by the video networking client, wherein the target DNS request is generated after the video networking client processes the DNS request, and the DNS request is generated when a superior program of the video networking terminal requests to access a target Internet website;

step S32: analyzing the target DNS request to obtain a domain name of the target internet website;

step S33: if the format of the domain name is a video networking format, inquiring a pre-stored domain name-IP corresponding relation table to obtain a first IP address matched with the domain name;

step S34: and returning the first IP address to the video network client, wherein the video network client is used for sending the first IP address to the superior program so that the superior program can access the target Internet website deployed in the video network according to the first IP address.

In the embodiment of the application, a domain name server of the video network receives a target DNS request sent by a client of the video network, and resolves the target DNS request to obtain a domain name therein. If the format of the domain name is judged to be the video networking format, a locally stored domain name-IP corresponding relation table is inquired, a first IP address corresponding to the domain name in the video networking is obtained, and the first IP address is returned to the video networking client, so that a superior program can access a target Internet website deployed in the video networking through a video networking way.

Fig. 5A is a schematic diagram of a domain name-IP correspondence table according to an embodiment of the present application. Illustratively, in fig. 5A, the IP corresponding to the domain name baidu is 10.0.0.1, and the IP corresponding to the domain name google is 10.0.0.2.

The detailed description of the above steps S31-S34 can also refer to the above description.

With reference to the foregoing embodiment, in another implementation manner, if the domain name server of the video network does not query the first IP address, the domain name server of the video network may further perform the steps shown in fig. 6, so as to ensure that the upper-level program of the video network terminal can finally access the target internet website. Fig. 6 is a flowchart illustrating a fourth method for accessing an internet site according to an embodiment of the present application.

2. Video networking packet definition

2.1 Access network packet definition

The data packet of the access network mainly comprises the following parts: destination Address (DA), Source Address (SA), reserved bytes, payload (pdu), CRC.

As shown in the following table, the data packet of the access network mainly includes the following parts:

DA

SA

Reserved

Payload

CRC

wherein:

the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;

the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);

the reserved byte consists of 2 bytes;

the payload part has different lengths according to different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;

the CRC consists of 4 bytes and is calculated in accordance with the standard ethernet CRC algorithm.

2.2 metropolitan area network packet definition

The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.

In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x 0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.

As shown in the following table, the data packet of the metro network mainly includes the following parts:

DA

SA

Reserved

label (R)

Payload

CRC

Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
