Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The transparent transmission method provided by the embodiment of the invention is applied to the video network. Unlike the internet architecture, in order to improve the security of the network in the video network, the local area networks in the video network are isolated from each other, and the network node relationship is unknown. In each local area network, a video network access server, a video network domain name server, a domain name inquiry terminal, a web page server and other devices can be included. The video network access server is used for providing a transparent transmission service, one terminal number can access a local area network where another terminal number is located through the transparent transmission service, and an IP (Internet Protocol) address for locally using the transparent transmission service is associated with a remote terminal number. The domain name server of the internet of view is used for managing domain names in a local area network where the domain name server is located, and domain name registration, domain name resolution and the like can be provided for Hyper Text Transfer Protocol (HTTP) services in the internet of view. The domain name server of the video network can be hardware or software, for example, a monitoring access service system server can be used as the domain name server of the video network. The domain name is the name of a computer or a group of computers on the Internet (network) composed of a string of characters separated by dots, and is used for positioning and identifying the computer during data transmission. For example, www.baidu.com is the domain name. The domain name query terminal refers to a device which can access the video network, such as a device provided with a browser.
Next, the transparent transmission method in the embodiment of the present invention will be described in detail.
Example one
Referring to fig. 1, a flowchart illustrating steps of a transparent transmission method according to a first embodiment of the present invention is shown. The transparent transmission method of the embodiment of the invention can be applied to a video network access server in a local area network. The domain name inquiry terminal, the first video network domain name server and the video network access server in the embodiment of the invention are positioned in the same local area network, and the destination end of the transparent transmission is positioned outside the local area network.
The transparent transmission method of the embodiment of the invention can comprise the following steps:
When a domain name query terminal located in a certain local area network wants to access web servers located in other local area networks, the domain name query terminal can initiate domain name query to a first video network domain name server located in the local area network so as to query information of the web server corresponding to a target domain name. The first video network domain name server acquires the terminal number of the transparent transmission destination end corresponding to the target domain name inquired by the domain name inquiry terminal and the information of the webpage server corresponding to the target domain name. The first video network domain name server informs the video network access server in the local network of which domain name inquiry terminals currently apply for domain name inquiry, and sends the IP address of the domain name inquiry terminal and the terminal number of the transparent transmission destination terminal to the video network access server in the local network.
The video network access server receives the IP address of the domain name inquiry terminal and the terminal number of the transparent transmission destination terminal sent by the first video network domain name server in the local domain network. The video network access server can know the domain name inquiry terminal which is going to initiate the access request subsequently according to the IP address of the domain name inquiry terminal, and can know the destination terminal which is going to forward the access request sent by the domain name inquiry terminal subsequently according to the terminal number of the destination terminal which is transmitted transparently, therefore, the video network access server establishes the mapping relation between the IP address and the terminal number, and allocates the access resource for the domain name inquiry terminal.
And step 102, the video network access server returns the information of the access resource to the domain name inquiry terminal through the first video network domain name server.
After allocating the access resource for the domain name query terminal, the access server of the video network returns the information of the access resource allocated for the domain name query terminal to the domain name query terminal. The video network access server returns the information of the access resource to the first video network domain name server, and then the information of the access resource is returned to the domain name inquiry terminal through the first video network domain name server.
After receiving the information of the access resources allocated to the domain name inquiry terminal by the video network access server, the domain name inquiry terminal can establish connection with the video network access server according to the information of the access resources allocated to the domain name inquiry terminal by the video network access server and send an access request to the video network access server. And after receiving the access request sent by the domain name inquiry terminal, the video network access server determines the terminal number corresponding to the domain name inquiry terminal according to the stored mapping relation.
And 104, the video network access server transparently transmits the access request by taking the terminal number as a destination end.
In the embodiment of the invention, before the domain name inquiry terminal initiates the webpage access request, the first video network domain name server informs the video network access server of the IP address of the domain name inquiry terminal and the terminal number of the transparent transmission destination terminal, so that the video network access server can know which domain name inquiry terminal is to initiate the access request in advance and allocate access resources for the domain name inquiry terminal which is to initiate the access request in advance to prepare services. The access resources are dynamically allocated and automatically negotiated based on the use requirements of the domain name inquiry terminals, and a plurality of domain name inquiry terminals in the same local area network can commonly use the transparent transmission service of the same video network access server, so that the efficiency of the video network access server is effectively improved, and the transparent transmission efficiency is improved.
Example two
Referring to fig. 2, a flowchart illustrating steps of a transparent transmission method according to a second embodiment of the present invention is shown. The transparent transmission method of the embodiment of the invention is applied to the access server of the video network in the local area network.
The transparent transmission method of the embodiment of the invention can comprise the following steps:
The video network comprises a video network core server, wherein the video network core server is a central device of the video network and is used for forwarding a video network instruction, establishing a video multicast address, allocating a video stream and the like. The video networking domain name server may be communicatively coupled to a video networking core server. All devices used in the video network are required to perform network access operation. For example, the network can be accessed through a virtual terminal number, and the virtual terminal number registers the online state on a video network core server through a video network access protocol and is ready to receive or send a video network instruction. When the network is accessed, the video network core server broadcasts a network access instruction and receives a response network access instruction sent by the network access equipment. The video network domain name server is used as a special network access device, so that the response network access instruction sent by the video network domain name server can carry indication information indicating that the network access device is the video network domain name server, and the video network core server can mark the network access device as the video network domain name server according to the indication information. The core server of the video network may store the IP address of each domain name query terminal after network access, the terminal number of the domain name query terminal, and information of each domain name server after network access, where the information of the domain name server of the video network may include one or more of the following information: IP address, terminal number, domain name list, etc. The equipment which is accessed to the network in the video network has a unique terminal number, and the equipment can communicate based on the terminal number.
The domain name inquiry terminal initiates domain name inquiry to a first video network domain name server, and the first video network domain name server acquires the terminal number of a transparent transmission destination end corresponding to a target domain name inquired by the domain name inquiry terminal and the information of a webpage server corresponding to the target domain name.
If the mode that the video network access server allocates the access resources for the domain name query terminal in advance is not adopted in the embodiment of the invention, the first video network domain name server returns the information of the web server corresponding to the acquired target domain name to the domain name query terminal. The domain name inquiry terminal initiates an access request to the video network access server, the video network access server configures the domain name inquiry terminal and the web server to form a one-to-one mapping relation, and other domain name inquiry terminals can not access the web server through the video network access server.
If the mode that the video network access server allocates the access resources for the domain name inquiry terminal in advance is adopted, the first video network domain name server does not return the information of the web server corresponding to the target domain name to the domain name inquiry terminal temporarily, but sends the IP address of the domain name inquiry terminal and the terminal number of the destination terminal of the transparent transmission to the video network access server. After receiving the IP address of the domain name inquiry terminal and the terminal number of the destination end transmitted through, which are sent by the first domain name server, the video network access server establishes the mapping relation between the IP address and the terminal number, and allocates access resources for the domain name inquiry terminal. Wherein the allocated access resource may include a physical resource (such as a port) for connecting with the domain name querying terminal, a computing resource (such as a cache, etc.) for forwarding the access request, and the like.
In an alternative embodiment, a task queue may be preset in the access server of the internet of view, and the access server of the internet of view stores the mapping relationships through the task queue, and one mapping relationship may be understood as a transparent transmission task. Therefore, after the mapping relationship between the IP address and the terminal number is established, the video network access server inserts the mapping relationship into the tail of a preset task queue. Under a normal condition, a domain name query terminal which receives information of access resources allocated by a video network access server first initiates an access request to the video network access server, and if a mapping relation corresponding to the domain name query terminal is at the front position of a task queue, the time required for finding a terminal number corresponding to the domain name query terminal in the task queue is less, so that the processing efficiency of the video network access server is improved in a way of storing the mapping relation through the task queue.
And the video network access server returns the information of the access resource allocated to the domain name inquiry terminal to the first video network domain name server. After receiving the information of the access resource, the first video network domain name server returns the IP address of the video network access server, the information of the access resource and the information of the web server corresponding to the target domain name to the domain name inquiry terminal.
The information of the access resource returned by the access server of the video network may include a port number of a port allocated for the domain name query terminal. The information of the web server may include an IP address and a port number of the web server.
After receiving the information of the IP address and access resource of the video network access server (the port number allocated to the domain name query terminal by the video network access server) and the IP address and port number of the web server corresponding to the target domain name, the domain name query terminal may establish a TCP (Transmission Control Protocol) connection with the video network access server according to the IP address of the video network access server and the port number allocated to the domain name query terminal by the video network access server. The domain name query terminal generates an access request (for example, the access request may be an HTTP request), and the access request may include an IP address of the domain name query terminal, an IP address and a port number of the web server, and the like. And the domain name inquiry terminal sends the access request to the video network access server through the TCP connection established between the domain name inquiry terminal and the video network access server.
After receiving a webpage access request sent by a domain name inquiry terminal, the video network access server searches for a terminal number corresponding to the domain name inquiry terminal according to the IP address of the domain name inquiry terminal. In an optional implementation manner, if the mapping relationship is stored according to the manner of the task queue, the access server of the internet of view searches the terminal number corresponding to the domain name query terminal from the head of the task queue according to the IP address of the domain name query terminal.
And step 204, the video network access server transparently transmits the access request by taking the terminal number as a destination end.
The access server of the video network can know the destination terminal to which the access request sent by the domain name inquiry terminal is to be transmitted according to the terminal number corresponding to the searched domain name inquiry terminal. The video network access server can be in communication connection with the destination end of the transparent transmission based on the terminal number of the destination end of the transparent transmission through the video network instruction. The access request includes complete link layer-application layer protocol content, and the view network access server may utilize the access resource (specifically, may include a computing resource) allocated for the domain name query terminal, and use the content of the entire access request (including all data from the link layer to the application layer) as the load of the view network instruction. The video networking instruction may include a Media Access Control (MAC) address of the video networking Access server as a source MAC address, a terminal number of the video networking Access server as a source terminal number, and a terminal number of the transparent destination terminal as a destination terminal number. And the video networking access server sends the video networking instruction to a video networking core server, and the video networking core server sends the video networking instruction to the transparent transmission destination terminal after receiving the video networking instruction and analyzing to obtain the terminal number of the transparent transmission destination terminal.
After receiving the video networking instruction, the transparent transmission destination terminal analyzes the video networking instruction to obtain the load, namely the access request, and can forward the access request to the corresponding web server through the information (IP address and port number) of the web server included in the access request. Therefore, the access request sent by the domain name inquiry terminal is sent to the corresponding webpage server. And after receiving the access request, the webpage server obtains corresponding webpage data and returns the webpage data.
In an optional implementation manner, the destination of the transparent transmission may be a second domain name server of the video network in the local area network where the web server corresponding to the target domain name is located.
After sending out the access request, the access server of the video network completes the transparent transmission service required by the domain name query terminal in the current access, so that the access server of the video network can release the access resources allocated to the domain name query terminal, so that other domain name query terminals can use the access resources. The video network access server also deletes the mapping relation corresponding to the domain name query terminal so as to release the corresponding memory in the task queue, and the next sequence of the mapping relation corresponding to the domain name query terminal in the task queue is positioned at the front position of the queue.
EXAMPLE III
Referring to fig. 3, a flowchart illustrating steps of a transparent transmission method according to a third embodiment of the present invention is shown. The transparent transmission method provided by the embodiment of the invention is applied to a first video network domain name server in a local area network.
The transparent transmission method of the embodiment of the invention can comprise the following steps:
When a domain name query terminal located in a certain local area network wants to access a web server located in another local area network, the domain name query terminal can initiate domain name query to a first video network domain name server located in the local area network so as to query information of the web server corresponding to a target domain name. The first video network domain name server acquires the terminal number of the transparent transmission destination end corresponding to the target domain name inquired by the domain name inquiry terminal and the information of the webpage server corresponding to the target domain name. And the first video network domain name server sends the IP address of the domain name inquiry terminal and the terminal number of the destination terminal of the transparent transmission to the video network access server.
After receiving the IP address of the domain name inquiry terminal and the terminal number of the destination end transmitted by the first video network domain name server, the video network access server establishes the mapping relation between the IP address and the terminal number, allocates access resources for the domain name inquiry terminal, and returns the information of the access resources to the first video network domain name server.
After receiving the information of the access resource returned by the video network access server, the first video network domain name server returns the IP address of the video network access server, the information of the access resource and the information of the web server corresponding to the target domain name to the domain name inquiry terminal.
And the domain name inquiry terminal sends an access request to the video network access server according to the information of the access resource, and after receiving the access request, the video network access server determines a terminal number corresponding to the domain name inquiry terminal according to the mapping relation and transparently transmits the access request by taking the terminal number as a destination terminal.
