Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure proposes a communication method, which can improve the effectiveness of network acceleration, and is described below with reference to fig. 1.
Fig. 1 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 1, the method of this embodiment includes: steps S102 to S108.
In step S102, a reply message of the DNS (Domain Name System) is received.
In some embodiments, the home gateway receives an access request of a user, forwards the access request of the user to the communication device of the present disclosure, and the communication device sends a request message to the DNS and receives a reply message of the DNS. The DNS performs operations such as domain name resolution, and the technology belongs to the prior art and is not described any more. The request message carries the domain name which the user requests to access, and the reply message comprises: and the IP address corresponding to the domain name which the user requests to access. The communication device may also acquire the reply message of the DNS by means of interception or the like.
Further, the domain name of the user to be accelerated may be received, for example, the user configures the domain name of the application or website to be accelerated through a client or a Portal page, and the configuration information is uploaded to the communication device. The communication device sends the domain name to be accelerated or the matching rule of the domain name to the home gateway and writes the domain name into the home gateway. When the home gateway receives an access request of a user for a domain name to be accelerated, the access request is forwarded to the communication device. The matching rule of the domain name is, for example, a keyword of the domain name. The home gateway can determine the domain name which the user requests to access as the domain name to be accelerated through keyword matching.
In step S104, time delay information of the IP address corresponding to the domain name through the normal path and the accelerated path is detected, respectively, and a corresponding network path is selected for the domain name.
In some embodiments, the regular path is the transmission path of traffic without accelerating the traffic. Conventional paths include, for example, paths from a metro network Core Router (CR) to the IP address. The acceleration path includes, for example, a path from an LNS (Layer 2Tunneling Protocol Access manager) to the IP address.
In some embodiments, when the reply packet includes a plurality of IP addresses, that is, when the domain name resolution obtains a plurality of IP addresses, the delay information from the conventional path to each IP address through the acceleration path is detected, and the network path with the lowest delay and the corresponding IP address are selected for the domain name. If the time delay of the metropolitan area network CR reaching the IP address is lower, selecting a path of the metropolitan area network CR reaching the IP address as a network path corresponding to the domain name; and if the time delay of the LNS server to reach the IP address is lower, selecting the IP address with the lowest time delay in the resolution result and the corresponding acceleration path as the network path corresponding to the domain name.
In step S106, when the selected network path is an acceleration path, the acceleration policy is sent to the home gateway.
And under the condition that the selected network path is a conventional path, the home gateway is not required to carry out configuration of an acceleration strategy, and the flow corresponding to the domain name is still transmitted normally. Therefore, the accelerating strategy does not need to be issued, and only the reply message of the DNS needs to be forwarded to the home gateway.
In some embodiments, in the case that the selected network path is an acceleration path, the acceleration policy includes: the IP address corresponding to the network path. Under the condition that the DNS reply message carries a plurality of IP addresses, the DNS reply message may be reassembled to carry the IP addresses corresponding to the network paths. After the acceleration policy is sent to the home gateway, the home gateway may store the IP address in the acceleration policy.
Further, the acceleration policy may further include tunnel configuration information corresponding to the network path. The tunnel configuration includes, for example: configuration information of an L2TP (Layer 2Tunneling Protocol) tunnel or a PPTP (Point to Point Tunneling Protocol) tunnel. The configuration information of the L2TP tunnel or the PPTP tunnel is, for example, a user name, a password, etc. corresponding to the tunnel. The home gateway can establish a tunnel according to the tunnel configuration information and send the traffic corresponding to the domain name to the corresponding IP address through the tunnel. The tunnel configuration information may be issued through an acceleration policy, or may be sent to the home gateway by the communication device when the home gateway is initially configured or when the user configures a domain name to be accelerated. The tunnel configuration process is completed before the traffic is transmitted through the tunnel, and the execution sequence is not limited.
In step S108, the home gateway transmits traffic corresponding to the domain name according to the acceleration policy.
In some embodiments, the home gateway stores the IP address in the acceleration policy, for example, and traffic of the domain name requested to be accessed by the subsequent user is transmitted to the corresponding stored IP address through the acceleration path (e.g., acceleration tunnel). When the user initiates the access to the domain name corresponding to the IP address again, the home gateway forwards the access request and receives the reply information returned by the communication device, wherein the reply information carries the stored IP address. The home gateway continues to transmit the traffic with the destination address being the saved IP address through the acceleration path.
In the method of the embodiment, the IP address corresponding to the domain name requested by the user is analyzed by acquiring the reply message from the DNS, and the delay information from the conventional path to the IP address through the acceleration path is detected, so as to determine the network path corresponding to the domain name. The home gateway only needs to receive and configure the acceleration strategy, does not need to analyze DNS messages and the like, and reduces the expense of the home gateway. By detecting the time delay of different paths, the effectiveness of network acceleration is improved, the flexibility of strategy configuration can be accelerated, and the resource occupation of the acceleration path is reduced.
In order to adapt to the changing network environment, the acceleration policy, the configuration of the home gateway, and the like need to be updated, which is described below with reference to fig. 2.
Fig. 2 is a flow chart of further embodiments of the communication method of the present disclosure. As shown in fig. 2, the method of this embodiment includes: steps S202 to S220.
In step S202, the user configures a domain name corresponding to the application or website to be accelerated, and sends the domain name to be accelerated to the communication device.
The user configures, for example through a client or Portal page, a domain name of an application or website to be accelerated.
In step S204, the communication device writes the domain name matching rule to be accelerated into the home gateway.
The matching rules include, for example, the domain name to be accelerated or the keywords of the domain name to be accelerated.
In step S206, the communication device sends an acceleration function start instruction to the home gateway, and accordingly, the home gateway starts the acceleration function in response to the acceleration function start instruction.
The acceleration function start instruction includes, for example: and accelerating tunnel configuration information corresponding to the path. The tunnel configuration information includes, for example: the username and password of the L2TP tunnel or point-to-PPTP tunnel, etc. The communication device may start the acceleration function of the home gateway in response to the domain name to be accelerated configured by the user, or may start the acceleration function of the home gateway through the issuing process of the acceleration policy in the subsequent process, which is not limited to the illustrated example. The acceleration function of the home gateway is started in advance, the subsequent configuration time is shortened, the flow can be accelerated in time, and the efficiency is improved.
In step S208, the home gateway receives an access request initiated by a user, and determines whether the access request is for a domain name to be accelerated according to a matching rule. If so, step S210 is performed, otherwise step S209 is performed.
The home gateway determines whether the access request is for the domain name to be accelerated by matching the stored matching rule.
In step S209, the home gateway initiates a request message to the DNS.
In step S210, the home gateway transmits the request packet to the communication device, and the communication device forwards the request packet to the DNS.
The home gateway does not need to send the request message to the communication device every time through the matching rule, thereby reducing the signaling overhead.
In step S212, the communication device receives a reply message returned by the DNS.
The reply message carries the IP address corresponding to the domain name to be accelerated.
In step S214, the communication device detects delay information of the IP address corresponding to the domain name to be accelerated through the normal path and the acceleration path, respectively, and selects a corresponding network path for the domain name to be accelerated. If the selected network path is a regular path, step S215 is performed, otherwise, step S216 is performed.
The reply message may carry a plurality of IP addresses corresponding to the domain name to be accelerated, and the time delay from the metropolitan area network CR to each IP address, the IP address with the lowest selection time delay from the LNS server to each IP address, and the corresponding acceleration path are respectively detected as the network path corresponding to the domain name.
In step S215, in the case that the selected network path is a normal path, the communication device forwards the reply packet of the DNS to the home gateway.
In step S216, in the case that the selected network path is an acceleration path, the communication device sends the reply message and the acceleration policy to the home gateway.
The acceleration policy includes, for example, an IP address corresponding to the selected network path, and a corresponding aging time. The communication device can also recombine the reply message, carry the IP address corresponding to the taken network path, and send the reply message to the home gateway.
In step S218, the home gateway stores the acceleration policy.
The home gateway stores the IP address and the corresponding aging time.
In step S220, the home gateway accelerates the traffic corresponding to the stored IP address through an acceleration path within the corresponding aging time.
The aging time is, for example, a time period, and when the aging time corresponding to the IP address expires, the home gateway may delete the IP address and the corresponding aging time, and then transmit the traffic of the user through the conventional path.
The steps in the method are the process that the user initially configures the domain name to be accelerated and the communication device configures the home gateway. In case the acceleration policy has been configured at the home gateway for the domain name the user wants to accelerate, the steps as shown in fig. 3 may be performed.
Fig. 3 is a flow chart of further embodiments of the communication method of the present disclosure. As shown in fig. 3, the method of this embodiment includes: steps S302 to S306, which may be performed after step S212.
In step S302, the communication device determines whether the domain name the user requests to access has configured the corresponding acceleration policy and whether the current time is within the corresponding aging time range, if so, step S304 is executed, otherwise, steps S214 and the following steps are executed according to the above embodiment.
In step S304, the communication device transmits a reply message of the reassembled DNS to the home gateway.
The reply message of the recombined DNS comprises the IP address in the configured acceleration strategy. The communication device does not need to reissue the acceleration policy.
In step S306, the home gateway accelerates the traffic corresponding to the stored IP address through the acceleration path within the corresponding aging time.
And the home gateway still sends the traffic corresponding to the domain name to be accelerated to the stored IP address through the acceleration path within the aging time.
After the aging time is over, both the communication device and the home gateway may delete the corresponding aging time information or the acceleration policy. And the user initiates a request for the domain name to be accelerated again, and the processing is carried out according to the methods of the steps S208 to S220.
In some embodiments, the user may delete or modify the domain name to be accelerated. The user sends a domain name deletion request to the communication device through the home gateway. And the communication device issues an acceleration strategy deletion command to the home gateway. The home gateway deletes the acceleration strategy corresponding to the domain name to be deleted by the user, and then transmits the flow corresponding to the domain name to be deleted through a conventional path.
In some embodiments, the user may directly configure the IP address corresponding to the application or website to be accelerated, and the IP address may be directly written into the home gateway as an acceleration policy. And the home gateway accelerates the flow corresponding to the IP address through an acceleration path.
The method of the embodiment selects an effective network path for the domain name to be accelerated by the user, can optimize the application access effect, selects the optimal scheme when the user accesses the configured domain name, does not have the condition of acceleration but not acceleration, and simultaneously avoids the occupation of the resources of the LNS server by the flow. The aging time updating acceleration strategy is configured, so that the configuration is flexible, and the acceleration rules are ensured to be updated according to the requirement instead of long-term static storage. And the analyzing function of the DNS message is moved up to the platform side, the performance expense of the home gateway is small,
some application examples of the communication method of the present disclosure are described below.
(1) The user configures the domain name www.example.com as the domain name to be accelerated, and the domain name www.example.com or the keyword is issued to the home gateway for storage.
(2) The home gateway matches www.example.com the key in all DNS request messages and sends the request message to the control platform.
(3) The communication device obtains www.example.com the domain name resolution result, i.e. the corresponding IP address, and the time delay of detecting the corresponding IP address from the metro network CR and the LNS server corresponding to the user is smaller than the time delay of detecting the corresponding IP address from the metro network CR and the LNS server corresponding to the user. If the access time delay between the metropolitan area network CR and the IP address is low, directly sending a DNS reply message to the home gateway; otherwise, on the basis of replying the message, the message is sent to the home gateway, wherein the message contains the IP address with the lowest time delay, and the acceleration strategy is sent to the home gateway. The speed-up policy includes the IP address with the lowest latency and the corresponding aging time (e.g., 15 minutes).
(4) In the next 15 minutes, the traffic accessed www.example.com by the user enters the acceleration tunnel according to the acceleration policy, during which the DNS message is still sent up, but the previous message can be directly replied.
(5) After 15 minutes, the acceleration policy has aged and automatically deleted, and if the user no longer accesses www.example.com, the previous acceleration policy will not be used, and if the user accesses www.example.com again, the communication device re-executes steps (3) and following after receiving the DNS message.
