Description
Technical Field
The invention relates to the technical field of network acceleration, in particular to an application acceleration method and system based on a dynamic routing protocol.
Background
DNS is the underlying protocol for the Internet and can be used to perform domain name to IP address translation.
In the prior art, intelligent DNS resolution can realize that different IP addresses are selected for DNS response according to a source IP address, for example, when a netcom user performs DNS query, an IP address of a netcom server is preferentially returned. However, there are the following problems:
firstly, manual configuration is needed, and the configuration amount is large. Intelligent DNS resolution requires configuration to be performed on a DNS server, and a DNS server administrator needs to know which IP addresses from which DNS requests return which resolved IP addresses. This has a very high requirement on the administrator of the DNS server, and particularly in the case of domain name hosting, when a certain DNS server undertakes resolution of hundreds of thousands of domain names, it is very heavy to complete similar configuration work one by one, and it is easy to make an error.
Second, less than optimal results. Assume that the intelligent DNS system returns A, B two IP addresses to the unicom user, where a is the preferred IP address. A. The order of B is usually self-determined by the DNS server, i.e. the DNS server detects that it accesses a faster on its own, but this does not mean that the end user accesses a faster as well.
In the prior art, a dynamic routing protocol is composed of a group of related protocols, and the purpose of the dynamic routing protocol is to establish a routing autonomous system in a certain area. In the autonomous system, the routing table does not need to be configured manually, and the routing table is automatically learned by using a related routing learning algorithm. However, the dynamic routing protocol is only a routing probe with a destination IP address as an object, and does not involve an upper layer application, so that optimization cannot be performed for a specific application.

Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. 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 invention.
Example 1
Referring to fig. 1 and fig. 2, embodiment 1 of the present invention provides an application acceleration method based on a dynamic routing protocol, including:
s1, receiving, by the DNS acceleration module 2, a DNS request of a given domain name initiated by the end user 1, and when the DNS request reaches the DNS acceleration module 2, querying the DNS cache 4 integrated in the DNS acceleration module 2:
s11, a) if the DNS cache 4 of the DNS acceleration module 2 queries the requested DNS record, the DNS acceleration module 2 performs a DNS response to the terminal user 1;
s12, b) if the DNS cache 4 of the DNS acceleration module 2 does not inquire the DNS record of the request, passing the DNS request to the DNS server 6;
s2, receiving DNS resolution and DNS response of the DNS server 6 to the DNS request through the DNS acceleration module 2, when the DNS response passes through the DNS acceleration module 2, the DNS acceleration module 2 resolving the server IP address in the DNS response message, and looking up the resolved server IP address in the routing table 5, if the lookup is successful, then:
s21, c) the DNS acceleration module 2 sorts the analyzed server IP addresses from small to large according to the connection speed in the routing table 5, and reconstructs DNS response messages according to the sorting;
s22, otherwise, d) the DNS acceleration module 2 informs the dynamic routing module 3, and the dynamic routing module 3 judges the connection speed of the analyzed server IP address.
In S21 of this embodiment, the reconstructed DNS response message is sent to the end user 1, and the content of the DNS response message is written into the DNS cache 4. In S22, the dynamic routing module 3 determines the connection speed of the resolved server IP address through detection and selection.
In this embodiment, the method further includes updating the connection speed result of the server IP address determined and analyzed by the dynamic routing module 3 into the routing table 5, and updating the connection speed result of the server IP address determined and analyzed by the dynamic routing module 3 into the DNS cache 4.
In the practical application process of the invention, the invention can be applied to a classic gateway firewall deployment mode, and the gateway is required to complete the function of P2P recognition by simultaneously passing the internet traffic and DNS traffic of the terminal user 1 through the gateway. The DNS acceleration module 2, the DNS cache 4, the routing table 5 and the dynamic routing module 3 are used as an application accelerator to perform application acceleration.
Assume that end user 1 needs to access application a, whose corresponding domain name is service. The end user 1 initiates a DNS query of service aaa com to the DNS server 6, which query passes through the DNS acceleration module 2. When receiving the DNS request, the DNS acceleration module 2 needs to perform DNS cache 4 lookup, and there are two cases at this time:
in case one, a record of service aaa com is recorded in the DNS cache 4, and the record is directly returned to the terminal user 1 as a DNS reply packet, and the whole acceleration process is completed;
in case two, if no record of service aaa com is recorded in the DNS cache 4, the DNS request packet is passed to the DNS server 6.
In case two, after the DNS server 6 receives the DNS request, DNS resolution is performed, and a resolution result is returned. Assuming that the resolution result is two IP addresses 1.1.1.1/1.1.1.2, wherein 1.1.1.1 is the best result considered by the DNS server 6 and is the preferred IP address, the DNS resolution result also passes through the DNS acceleration module 2.
After receiving the DNS reply message, the DNS acceleration module 2 sequentially performs the following operations:
(1) analyzing the DNS response message to sequentially analyze two IP addresses of 1.1.1.1 and 1.1.1.2;
(2) the DNS acceleration module 2 looks up the records in the routing table 5 for 1.1.1.1 and 1.1.1.2, and if found, proceeds to (4); otherwise, the DNS acceleration module 2 informs the dynamic routing module 3 to search the connection speed of the two IP addresses analyzed in the step (1);
(3) after receiving the service request of the DNS acceleration module 2, the dynamic routing module 3 performs route detection and selection, mainly determining the connection speed of 1.1.1.1 and 1.1.1.2. The calculation result of the dynamic routing module 3 will be updated to the routing table 5. Here, it is assumed that "connection speed (1.1.1.1)" is 20 and "connection speed (1.1.1.2) is 10". Here, the larger the "connection speed" is, the longer the time to the corresponding destination is;
(4) and the DNS acceleration module 2 sorts the IP addresses analyzed in the step (1) from low to high according to the connection speed in the routing table 5, and reconstructs DNS response messages according to the sequence. In this example, the order of the IP addresses in the reconstructed DNS reply message will become 1.1.1.2/1.1.1.1;
(5) the reconstructed DNS response message is sent to the terminal user 1; at the same time, the content of the response message, i.e. the "key-value" pair < service.aaa.com,1.1.1.2/1.1.1 > is written into the DNS cache 4.
(6) If the dynamic routing module 3 detects an update of the route, for example, it finds that "connection speed (1.1.1.1)" is 15 "and" connection speed (1.1.1.2) "is 30" for a certain period of time. Besides the need to update the routing table 5, the DNS cache 4 needs to be notified to update the DNS cache 4, and the cached < service.aaa.com,1.1.1.2/1.1.1.1> is updated to < service.aaa.com,1.1.1.1/1.1.1.2 >.
(7) After receiving the DNS response, in this example, 1.1.1.2/1.1.1.1, the end user 1 will first select the first IP address for service access, that is, access the application server 1.1.1.2, instead of the first IP address 1.1.1.1 returned by the DNS server 6, thereby achieving the effect of application acceleration.
In summary, the present invention receives, through the DNS acceleration module 2, a DNS request of a given domain name initiated by the end user 1, and when the DNS request reaches the DNS acceleration module 2, queries the DNS cache 4 integrated in the DNS acceleration module 2: if the DNS cache 4 of the DNS acceleration module 2 inquires the requested DNS record, the DNS acceleration module 2 carries out DNS response on the terminal user 1; if the DNS cache 4 of the DNS acceleration module 2 does not inquire the DNS record of the request, the DNS request is released to a DNS server 6; receiving DNS analysis and DNS response of a DNS server 6 to a DNS request through a DNS acceleration module 2, when the DNS response passes through the DNS acceleration module 2, analyzing a server IP address in a DNS response message by the DNS acceleration module 2, searching the analyzed server IP address in a routing table 5, if the searching is successful, switching to the DNS acceleration module 2 to sort the analyzed server IP address from small to large according to the connection speed in the routing table 5, and reconstructing the DNS response message according to the sorting; otherwise, the DNS acceleration module 2 notifies the dynamic routing module 3, and the dynamic routing module 3 determines the connection speed of the resolved server IP address. The invention can dynamically reflect the change of the route to the DNS result in an adaptive system, thereby accelerating the access speed of the application; DNS service configuration is not easy to make mistakes, and can be dynamically changed, so that a DNS system is also self-adaptive and more intelligent.

a DNS server 6, configured to receive a DNS request released by the DNS acceleration module 2 if a DNS record of the request is not queried in the DNS cache 4 of the DNS acceleration module 2; the DNS server 6 performs DNS resolution and DNS response on the DNS request;
the DNS acceleration module 2 receives the DNS response, the DNS acceleration module 2 analyzes the server IP address in the DNS response message, the analyzed server IP address is searched in the routing table 5, if the searching is successful, the DNS acceleration module 2 sorts the analyzed server IP address from small to large according to the connection speed in the routing table 5, and the DNS response message is reconstructed according to the sorting;
and the dynamic routing module 3 is configured to determine a connection speed of the analyzed server IP address after the failure of searching the analyzed server IP address in the routing table 5.
