Description

Redirection method and device

Technical field

The present invention relates to the field of communications technologies, and in particular, to a redirection method and apparatus.

Background technique

The player plug-in and player application are required when the user views the Internet video online through the browser. When playing a video, the browser first initializes the player plug-in, and the player plug-in executes the player application, requests video from the video server, and performs pauses, drags, and the like.

At present, most video websites can simultaneously use multiple video servers to provide video services to users at the same time. In order to effectively utilize resources, load balancing technology is usually used to load the video requests of users to each video server evenly. The process in which the load balancing server selects the video server is called content routing.

In the prior art, there are two kinds of content routing technologies, namely: content routing based on DNS (Doma in Name System) technology and content routing based on redirection technology.

Currently, the client's browser caches the IP address of the domain name resolved during the content routing process. When providing video services for users, if DNS-based content routing is used, the browser caches the IP address of the video server currently serving the customer; if content routing based on redirection technology is used, the browser caches Is the IP address of the load balancer. Within the browser's caching period, requests for any content under the same domain in the same web page will use the IP address in the cache. That is to say, when the video server currently provided for the client fails, the player does not re-initiate the DNS domain name resolution request, and the current video service will be interrupted, thereby affecting the user experience when watching the video.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 1, the first embodiment of the present invention provides a redirection method, including:

Step 11: The player receives the video content pointed by the first URL (Uniform Resource Loca tor) sent by the first video server. The first URL refers to a URL corresponding to the video content currently used by the user. For example, the user is currently watching the URL ht tp through the player: //video, demos i te. com/demo. The video content pointed to by mp4, then the ht tp: //video, demos i te. com/demo. Mp4 can be called the first URL here.

In this embodiment, the player obtains the video content pointed by the first URL sent by the first video server, which is obtained by means of content routing. In this step, the player can obtain the video content pointed by the first URL sent by the first video server in at least the following two ways.

Method 1: DNS-based content routing

In this mode, as shown in Figure 2, this step mainly includes the following process:

Step 111: When the player requests the video content pointed to by the first URL, the browser first initiates a DNS domain name resolution request to the DNS server, and parses the IP address represented by the domain name in the first URL.

Step 112: The DNS server sends the DNS domain name resolution request to the load balancer.

Step 113: The load balancer selects a suitable video server according to the distance between each video server and the client where the player is located, and the current resource usage of each video server, and sends the IP address of the video server to the player through the DNS domain name resolution response. . For convenience of description, in this embodiment, the selected video server is referred to as a first video server.

Step 114: The player sends a video request to the first video server according to the IP address of the first video server.

Step 115: The first video server sends the video content pointed by the first URL to the player.

Method 2, content routing based on redirection technology

In this mode, as shown in Figure 3, this step mainly includes the following process:

Step l l la, when the player requests the video content pointed to by the first URL, the browser first

The DNS server initiates a DNS domain name resolution request and parses the IP address represented by the domain name in the first URL.

Step 112a: The DNS server sends the IP address of the load balancer to the player through a DNS resolution response.

Step 113a: The player sends a video request to the load balancer according to the IP address of the load balancer. Step 114a, the load balancer is based on the distance between each video server and the client where the player is located, A suitable video server, that is, a first video server, is selected for each video server's current resource usage. Then, the load balancer sends a redirect message to the player, including the IP address of the first video server in the redirect message, and notifying the player to use the IP address of the first video server as the redirected IP address.

Step 115a: The player sends a video request to the first video server according to the IP address of the first video server.

Step 116a: The first video server sends the video content pointed by the first URL to the player. Of course, in a specific application, the player may have other ways to obtain the video content pointed by the first URL sent by the first video server, which is only an example.

Step 12: The player detects an working state of the first video server.

In this embodiment, the player can detect the number of bytes of video content pointed to by the first URL received from the first video server within a predetermined time; when the number of bytes received within the predetermined time is 0 The working state of the first video server is abnormal. When the number of bytes received in the predetermined time is not 0, the working state of the first video server is normal.

The predetermined time may be arbitrarily set, for example, 1 minute or the like. Of course, the player can also detect the working state of the first video server by other means.

Step 13: When the player detects that the working status of the first video server is abnormal, obtaining a second URL according to the first URL.

In this step, the player may add a prefix to the first URL to obtain the second URL. For example, the first URL is ht tp: //video, demos i te. com/demo. mp4 , and the second URL can be obtained by adding the prefix "new23415" to the first URL, which is ht tp: //new23415. video, Demos i te. com/ demo. mp4.

Of course, there may be other ways to modify the first URL, as long as the first URL and the second URL can be distinguished, which is merely an example.

Step 14: The player sends a video request, where the video request includes the second URL, so that the video server that receives the video request can obtain the first URL pointing according to the second URL in the video request. Video content. Since the second URL is not cached in the browser, the player will use the second URL to re-route the content. The process of performing content routing may also adopt content routing based on DNS technology or content routing based on redirection technology.

In the process of performing content routing, after receiving the DNS request of the DNS server or receiving the video request that the player includes the second URL, the load balancer needs to remove the prefix in the second URL to obtain the first A URL, then select the video server, and send the selected IP address of the working video server to the player.

Then, the player sends a video request including the second URL to a video server with a working state selected by the load balancer, so that the video server receiving the video request can be based on the video request. The second URL acquires the video content pointed to by the first URL. The video server that receives the video request includes a second video server as described below. Of course, it may also include a first video server whose working status is restored to normal.

Step 15. The player receives the video content pointed by the first URL sent by the second video server.

The second video server obtains the second URL according to the video request, removes the prefix of the second URL, obtains a first URL, and obtains the first URL according to the first URL. Video content. Then, the video content pointed by the first URL is sent to the player.

It can be seen from the above that in the case that the working status of the first video server is abnormal, the video content pointed by the first URL can still be obtained by the second video server, thereby ensuring the continuity or completeness of the video content pointed by the first URL. Sex. Therefore, with the redirection method of the embodiment of the present invention, the user does not interrupt when viewing the video content, thereby improving the user experience of watching the Internet video online.

Of course, in order to further ensure that the player can obtain the video content pointed to by the first URL, after step 13, the connection with the first video server can also be disconnected.

Step 23: When the working status of the first video server is abnormal, the player re-requests the video content pointed by the first URL by using the first URL.

In this step, the player can re-request the video content pointed to by the first URL to any video server. However, according to step 21, since the IP address of the first video server or the IP address of the load balancer is cached in the browser of the client, the player may move to the first video server or the load balancer to further improve the efficiency. Re-requesting the video content pointed to by the first URL.

When the IP address of the first video server is cached in the browser of the client, the specific process of the player re-requesting the video content pointed by the first URL to the first video server may include: the player according to the first video server The IP address sends a video request to the first video server, and then the first video server resends the video content pointed to by the first URL to the player. The first video server may resend the video content pointed by all the first URLs to the player, or in order to further improve the user experience, only the video content pointed to by the first URL obtained from the player may be The content after the interruption continues to be sent to the player.

When the IP address of the load balancer is cached in the browser of the client, the specific process of the player re-requesting the video content pointed to by the first URL to the load balancer may be:

The player sends a video request to the load balancer based on the IP address of the load balancer. The load balancer selects a suitable video server (the third video server in this embodiment) according to the distance between each video server and the client where the player is located, the current resource usage of the video server, and the like. The load balancer sends a redirect message to the player, includes the IP address of the third video server in the redirect message, and informs the player to use the IP address of the third video server as the redirected IP address, and then the player goes to the third The video server sends a video request and the third video server sends the video content to the player.

The third video server may resend the video content pointed by all the first URLs to the player, or in order to further improve the user experience, only the first player from the player may be The content after the video server obtains the interruption of the video content pointed to by the first URL continues to be sent to the player.

In the process of selecting a suitable video server by the load balancer, the load balancer may send a status request message to each video server, and each video server reports its own status through the status response message, and then the video server selects according to the status response message. The right video server. Alternatively, each video server may periodically report its own status information, and the video server selects a suitable video server according to the status information.

Step 24: When the re-request fails, the player obtains the second URL according to the first URL. For the specific process of this step, refer to the description of step 13 in the first embodiment of the present invention.

Step 25: The player sends a video request, and the second URL is included in the video request, so that the video server that receives the video request can obtain the first URL pointing according to the second URL in the video request. Video content.

The specific process of this step can be referred to the description of step 14 in the first embodiment of the present invention.

Step 26: The player receives the video content pointed by the first URL sent by the second video server.

For the specific process of this step, refer to the description of step 15 in the first embodiment of the present invention.

It can be seen from the above that in the case that the working status of the first video server is abnormal, the player can re-request the video content pointed to by the first URL or obtain the video content pointed by the first URL by modifying the URL, thereby ensuring the video content. The continuity or integrity of the video content pointed to by the first URL. Therefore, with the redirection method of the embodiment of the present invention, the user does not interrupt when viewing the video content, thereby improving the user experience of watching the Internet video online.
