Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
Before describing the embodiment of the present invention, a brief description is first given to a transmission process of P2P CDN service data. Specifically, when using the P2P CDN service, the intelligent gateway first needs to apply for an Internet data channel (Internet WAN) from the operator, and transmit P2P CDN service data by relying on the Internet data channel provided by the operator, that is: the intelligent gateway is connected with a corresponding server through the internet data channel and downloads data from the server or uploads data to the server, and the process has the following problems: on one hand, the uplink network bandwidth of the internet data channel is limited by the uplink network bandwidth configured by an operator, so that the process of uploading data by a user is often influenced by the limitation of the uplink network bandwidth, and the transmission efficiency of the uploaded data is low; on the other hand, in the process of downloading data, besides the P2P CDN service data, the internet data channel also contains various other types of service data, and these service data may occupy more or less transmission resources of the internet data channel and cannot distinguish the priority of each service data, which results in a long time delay for a user to download data through the internet data channel and a low transmission efficiency of the downloaded data.
Based on the existing problems, an embodiment of the present invention provides a P2P CDN service processing method, which is shown in fig. 1 and includes:
step S101: and the first intelligent gateway receives a video-on-demand instruction which is sent by the terminal through the first WAN connection and carries a video-on-demand information identifier.
Specifically, the first WAN is connected to an Internet WAN that the user applies for from the operator. The terminal can be a terminal device which can be connected with the first intelligent gateway and performs data interaction with the first intelligent gateway. For example, a mobile terminal such as a mobile phone or a tablet computer, or a PC (personal computer) terminal such as a notebook computer. And the terminal sends data to the first intelligent gateway through the Internet WAN or acquires the data from the first intelligent gateway.
In this step, the terminal sends a request order carrying a request information identifier to the first intelligent gateway through the Internet WAN of the first intelligent gateway, and the first intelligent gateway receives the request order through the Internet WAN. The on-demand information identifier may be information identifiers related to P2P CDN service data, such as video information, audio information, or web page information in the P2P CDN service. The on-demand information identification can uniquely identify the on-demand information.
For example, if the user a wants to watch the video 1 while browsing the video webpage by using the mobile phone, an on-demand instruction carrying the video 1 identifier is sent to the first intelligent gateway by using the mobile phone.
Step S102: and the first intelligent gateway sends the on-demand information identifier to the CDN platform.
Step S103: the CDN platform determines the connection information of at least one second intelligent gateway according to the on-demand information identifier; the connection information includes: a VLAN (Virtual Local Area Network) ID of the second intelligent gateway or an IP address of the second intelligent gateway.
Specifically, the first intelligent gateway sends an on-demand information identifier sent by the terminal to the CDN platform, and after receiving the on-demand information identifier, the CDN platform determines at least one second intelligent gateway according to the on-demand information identifier and determines connection information of the at least one second intelligent gateway. When the number of the second intelligent gateways is one, all data of the on-demand information corresponding to the on-demand information identifier are stored locally on the second intelligent gateway; when a plurality of second intelligent gateways are provided, partial data of the on-demand information corresponding to the on-demand information identification is locally stored in each second intelligent gateway, and all the partial data of the on-demand information identification stored in all the second intelligent gateways can obtain all the data of the on-demand information after being combined.
When determining the connection information of at least one second intelligent gateway, the CDN platform may first determine whether the first intelligent gateway and the second intelligent gateway access the same OLT (optical line terminal), and in a specific implementation, the manner of determining whether the first intelligent gateway and the second intelligent gateway access the same OLT may be set by a person skilled in the art according to an actual situation, for example, may determine whether a VLAN ID of the first intelligent gateway and a VLAN ID of the second intelligent gateway are within the same preset interval range (which is set by the person skilled in the art, but not limited by the present invention), if so, determine that the first intelligent gateway and the second intelligent gateway access the same OLT, otherwise, access different OLTs.
If the determined result is that the first intelligent gateway and the second intelligent gateway are accessed to different OLTs, the CDN platform acquires the IP address of the second intelligent gateway and sends a connection message carrying the IP address of the second intelligent gateway to the first intelligent gateway; if the determined result is that the first intelligent gateway and the second intelligent gateway have the same access to the OLT, the CDN platform queries a local database for the VLAN ID of the second intelligent gateway reported in advance by the second intelligent gateway, and sends a connection message carrying the VLAN ID of the second intelligent gateway to the first intelligent gateway. In a specific implementation, the reporting, by the second intelligent gateway to the CDN platform in advance, of the VLAN ID of the second intelligent gateway may specifically be: before executing the step, the second intelligent gateway receives a plug-in sent by the terminal in advance and installs the plug-in, so that the plug-in adds a second WAN connection only for the P2P CDN service on the second intelligent gateway through an underlying API (Application Program Interface), generates a VLAN ID corresponding to the second WAN connection, and reports the VLAN ID to the CDN platform as the VLAN ID of the second intelligent gateway. Further, the CDN platform receives the VLAN ID of the second intelligent gateway reported by the second intelligent gateway, and the CDN platform may store the correspondence between the VLAN ID of the second intelligent gateway and the second intelligent gateway in the local database, and after the second intelligent gateway is determined, obtain the VLAN ID of the second intelligent gateway according to the correspondence.
Step S104: and the first intelligent gateway receives a connection message which is sent by the CDN platform and carries the VLAN ID of the second intelligent gateway or the IP address of the second intelligent gateway.
Step S105: and the first intelligent gateway sends a data request message to the second intelligent gateway according to the connection message.
If the connection message carries the VLAN ID of the second intelligent gateway, the first intelligent gateway sends a data request message to the second intelligent gateway according to the VLAN ID;
if the connection message carries the IP address of the second intelligent gateway, the first intelligent gateway sends a data request message to the second intelligent gateway according to the IP address;
wherein, the data request message carries the request information identifier.
Step S106: and the second intelligent gateway responds to the data request message so that the first intelligent gateway can acquire target data corresponding to the on-demand information identifier from the second intelligent gateway through second WAN connection.
If the first intelligent gateway sends a data request message to the second intelligent gateway according to the VLAN ID, the second intelligent gateway responds to the data request message so that the first intelligent gateway can acquire target data corresponding to the on-demand information identification from the second intelligent gateway through a second WAN connection corresponding to the VLAN ID of the second intelligent gateway; or,
and if the first intelligent gateway sends a data request message to the second intelligent gateway according to the IP address, the second intelligent gateway responds to the data request message so that the first intelligent gateway can obtain the IP address of the second intelligent gateway, then the second intelligent gateway is positioned according to the IP address of the second intelligent gateway, and the target data corresponding to the on-demand information identifier is obtained from the second intelligent gateway through the second WAN connection of the second intelligent gateway.
Step S107: the first intelligent gateway inserts the target data into the first WAN connection so that the terminal can obtain the target data through the first WAN connection.
The second WAN connection is used for transmitting P2P CDN service data between the intelligent gateways, so that, after the first intelligent gateway obtains target data corresponding to the on-demand information identifier from the second intelligent gateway through the second WAN connection, the first intelligent gateway inserts the target data into the first WAN connection, that is, forwards the target data to the Internet WAN, so that the terminal obtains the target data through the Internet WAN.
Optionally, since the first WAN connection (i.e. Internet WAN) includes other types of service data besides the P2P CDN service data, before the step is executed, in order to enable the terminal to preferentially acquire the target data in the first WAN connection, the processing priority of the target data may be set to be the highest processing priority among the processing priorities of the data in the first WAN connection, so that the terminal can preferentially acquire the target data through the Internet WAN.
Therefore, in the P2P CDN service processing method provided in the embodiment of the present invention, after obtaining the on-demand information identifier from the terminal through the first WAN connection, the first intelligent gateway may send the on-demand information identifier to the CDN platform, so as to obtain, from the CDN platform, the VLAN ID of the second intelligent gateway or the IP address of the second intelligent gateway of the target data corresponding to the on-demand information identifier sent by the CDN platform according to the on-demand information identifier, then obtain, according to the VLAN ID or the IP address, the target data corresponding to the on-demand information identifier from the second intelligent gateway through the second WAN connection, and insert the target data into the first WAN connection, so that the terminal obtains the target data through the first WAN connection. Therefore, the embodiment of the invention can acquire or upload the target data through a second WAN connection dedicated to transmitting the P2P CDN service, and can insert the target data in the second WAN connection into the first WAN connection, so that the terminal can acquire the target data from the first WAN connection, thereby effectively avoiding the influence of the limitation of the uplink network bandwidth when the intelligent gateway uploads data, and the occurrence of the situation that the P2P CDN service data and other types of service data share the internet data channel, and improving the transmission efficiency of the P2P CDN service data.
