The embodiment of the invention provides a SaaS access optimization method, and referring to FIG. 2, FIG. 2 is a flow chart of a first embodiment of the SaaS access optimization method.
In this embodiment, the SaaS access optimization method includes the following steps:
step S10: and acquiring the domain name of the SaaS service to be accessed according to the DNS request.
It should be noted that, the execution body of the embodiment is a SaaS access optimized router, and may be other devices that may implement the same or similar functions, which is not limited in this embodiment, and the SaaS access optimized router is described as an example in this embodiment.
In an implementation, the DNS (Domain Name server, domain name service) request is sent by the user host, and the router may determine the domain name to access the SaaS service according to the sending of the user host.
Specifically, obtaining the domain name of the SaaS service to be accessed according to the DNS request specifically includes: when receiving the SaaS service request, determining to-be-accessed SaaS service; and when a DNS request sent by a user host is received, acquiring the domain name of the SaaS service to be accessed according to the DNS request.
It should be understood that the SaaS service request is initiated by a user at the back end of the enterprise exit router, and when the user needs to access the SaaS service, the SaaS service request is initiated, so that the SaaS service that the user needs to access, i.e. the SaaS service to be accessed, can be determined according to the SaaS service request. After the user sends the SaaS service request, the user host initiates a DNS request according to the SaaS service to be accessed, so that the IP address of the SaaS service to be accessed can be inquired through the DNS request, and when the exit router receives the DNS request sent by the user host, the domain name of the SaaS service to be accessed can be read out according to the DNS request.
Step S20: and inquiring the initial transmission optimization channel of the SaaS service to be accessed according to the domain name, and importing the DNS request into the initial transmission optimization channel.
It should be understood that a mapping relationship is established between the domain name and the transmission optimization channel of the SaaS service to be accessed, and the related transmission optimization channel can be configured in advance according to the domain name.
In this embodiment, for example, a transmission optimization channel of a SaaS service to be accessed with a domain name of a.com is set as an optimization channel 1, a transmission optimization channel of a SaaS service to be accessed with a domain name of b.com is set as an optimization channel 2, and the like, which is not limited in this embodiment, and a mapping relationship between the domain name and the transmission optimization channel of the SaaS service to be accessed is established, so that the transmission optimization channel of the SaaS service to be accessed can be quickly queried according to the domain name, and is used as an initial transmission optimization channel of the SaaS service to be accessed, and meanwhile, a received DNS request is imported into the initial transmission optimization channel.
Step S30: and when the DNS response of the initial transmission optimization channel is received, acquiring a network identification address pool.
It should be noted that, after the DNS request is led into the initial transmission optimization channel, the egress router monitors the DNS response in the initial transmission optimization channel in real time, and when the DNS response of the initial transmission optimization channel is received, the network identification address pool can be obtained according to the DNS response of the initial transmission optimization channel, where the network identification address pool is an IP address pool IP1, IP 1= [ IP1, IP2, ].
Further, the step of acquiring the network identifier address pool when the DNS reply of the initial transmission optimization channel is received specifically includes: detecting whether domain name response exists in the DNS response when the DNS response of the initial transmission optimization channel is received; and when detecting that the domain name response exists in the DNS response, extracting a network identification address pool from the domain name response.
It should be understood that when the egress router receives the DNS reply of the initial transmission optimization channel, it needs to determine whether there is a domain name reply according to the DNS reply, and when the egress router detects that there is a domain name reply, it parses the domain name reply, and extracts the network identifier address pool from the domain name reply. When the exit router receives the DNS response of the initial transmission optimization channel, resolving the DNS response to obtain CNAME (alias), then initiating a DNS request to the CNAME again, and monitoring the DNS response of the CNAME at the same time, thereby extracting a network identification address pool according to the DNS response of the CNAME.
Step S40: and obtaining a target transmission optimization channel according to a preset routing table and the network identification address pool.
In this embodiment, the preset routing table is a mapping relationship table between a network identifier address pool and a target transmission optimization channel, which are established in advance, and the final target transmission optimization channel can be obtained according to the preset routing table and the network identifier address pool.
Step S50: and obtaining a construction data packet, wherein the construction data packet comprises a target identification address.
After receiving DNS response returned by the exit router, the user host constructs a data packet with the destination address as the destination identification address.
For example, a packet with a destination address ip1 is constructed, where ip1 belongs to the network identifier address pool. And after the user host computer is constructed, obtaining a constructed data packet, and sending the constructed data packet to the port router.
Step S60: and when the target identification address of the constructed data packet is a preset address, importing the constructed data packet into the target transmission optimization channel based on the preset routing table so as to access the service flow of the SaaS service to be accessed.
It should be understood that, after the egress router receives the configuration data packet sent by the user host, the configuration data packet may be parsed, a target identifier address of the configuration data packet may be determined, and whether the target identifier address of the configuration data packet is a preset address is determined, where the preset address is set in advance, for example, ip1 in the network identifier address pool, and when the target identifier address is the preset address, the configuration data packet may be imported into the target transmission optimization channel according to the preset routing table, so as to access the traffic flow of the SaaS service to be accessed.
According to the embodiment, a domain name of a SaaS service to be accessed is obtained according to a DNS request; inquiring an initial transmission optimization channel of the SaaS service to be accessed according to the domain name, and importing the DNS request into the initial transmission optimization channel; when receiving the DNS response of the initial transmission optimization channel, acquiring a network identification address pool; obtaining a target transmission optimization channel according to a preset routing table and the network identification address pool; obtaining a construction data packet, wherein the construction data packet comprises a target identification address; when the target identification address of the construction data packet is a preset address, the construction data packet is imported into the target transmission optimization channel based on the preset routing table so as to access the service flow of the SaaS service to be accessed, and the optimized routing of the corresponding SaaS service can be completed by acquiring the domain name of the SaaS service without providing an IP address pool in advance or manually resolving the domain name, so that the configuration of the SaaS service is simplified, the problem of updating the IP address pool is solved, and the DNS request also passes through the obtained target transmission optimization channel, thereby improving the resolving accuracy.
Referring to fig. 3, fig. 3 is a flow chart of a second embodiment of the SaaS access optimization method of the present invention.
Based on the above-mentioned first embodiment, the SaaS access optimization method of this embodiment further includes, before the step S40:
step SA1: and acquiring the original network identification address pool data and the routing data.
It should be noted that, the original network identification address pool data is a large amount of network identification address pool data collected in the earlier stage, and the routing data is a large amount of collected routing data.
Step SA2: and obtaining the next hop data of the route according to the route data.
In a specific implementation, after the route data is collected, a route next hop of each route can be obtained according to each route in the route data, so that route next hop data is obtained in a summarizing mode.
Step SA3: and establishing a first mapping relation between the network identification address pool and the route next hop according to the original network identification address pool data and the route next hop data to obtain a preset routing table.
It should be understood that after the original network identification address pool data and the route next hop data are obtained, a mapping relationship between the network identification address pool and the route next hop, that is, a first mapping relationship, may be established according to the original network identification address pool data and the route next hop data, so as to obtain a preset routing table that characterizes the relationship between the network identification address pool and the route next hop. The first mapping relation is dynamically generated according to the original network identification address pool data and the route next hop data.
Specifically, after the preset routing table is established, the next route hop corresponding to the different network identifier address pools can be obtained by querying the preset routing table, and the step of obtaining the target transmission optimization channel according to the preset routing table and the network identifier address pools specifically includes: obtaining a target transmission optimization channel according to a preset routing table and the network identification address pool; inquiring a preset routing table based on the network identification address pool to obtain a next route hop corresponding to the network identification address pool; and taking the route next hop as a target transmission optimization channel.
After a preset routing table is queried according to the network identification address pool, a next route jump corresponding to the network identification address pool as a target address can be obtained, and the next route jump is used as an optimal transmission optimization channel, namely a target transmission optimization channel. And constructing a routing table to enable a next hop of the route corresponding to the network identification address pool to be used as a target transmission optimization channel.
The embodiment obtains the original network identification address pool data and the routing data; obtaining route next-hop data according to the route data; and establishing a first mapping relation between the network identification address pool and the route next hop according to the original network identification address pool data and the route next hop data to obtain a preset route table, modifying the corresponding route table through the corresponding relation between the record domain and the IP, so that the destination address is the route next hop of the network identification address pool and is the optimized channel, and improving the optimized effect.
Referring to fig. 4, fig. 4 is a schematic flow chart of a third embodiment of the SaaS access optimization method of the present invention.
Based on the first and second embodiments, step S60 of the SaaS access optimization method of the present embodiment specifically includes:
step S601: and receiving the construction data packet and analyzing the construction data packet.
Step S602: and obtaining the target identification address of the construction data packet according to the analysis result.
It should be understood that the destination identifier is included in the configuration data packet, so that after the egress router receives the configuration data packet sent by the user host, the configuration data packet may be parsed, so that the destination identifier of the configuration data packet may be obtained according to the parsing result.
Step S603: and when the target identification address of the construction data packet is the address in the network identification address pool, determining the target identification address of the construction data packet as a preset address.
In a specific implementation, when the destination identification address of the construction data packet is an address in the network identification address pool, the destination identification address of the construction data packet is determined to be a preset address. For example, if the destination identifier address of the constructed data packet is IP1, and IP1 belongs to the network identifier address pool IP1, it is determined that the destination identifier address of the constructed data packet is a preset address.
Step S604: and taking the route next hop corresponding to the network identification address pool as a target transmission optimization channel based on the preset routing table.
It should be understood that when the destination identifier address of the constructed data packet is a preset address, a route next hop corresponding to the destination identifier address may be obtained according to the constructed preset routing table, so that the route next hop is used as the destination transmission optimization channel.
Step S605: and importing the constructed data packet into the target transmission optimization channel, and accessing the service flow of the SaaS service to be accessed through the target transmission optimization channel.
After determining the optimal transmission optimization channel, the configuration data packet is imported into the target transmission optimization channel, so that the configuration data packet can be transmitted, and the service traffic of the SaaS service to be accessed can be accessed through the target transmission optimization channel.
The embodiment analyzes the construction data packet by receiving the construction data packet; obtaining a target identification address of the construction data packet according to the analysis result; when the target identification address of the construction data packet is the address in the network identification address pool, determining that the target identification address of the construction data packet is a preset address; taking the route next hop corresponding to the network identification address pool as a target transmission optimization channel based on the preset routing table; and importing the construction data packet into the target transmission optimization channel, accessing the service flow of the SaaS service to be accessed through the target transmission optimization channel, and modifying a corresponding routing table to enable the next hop of the reason of the target address IP to be the final optimization channel so as to improve the optimization effect of the SaaS access.

The original transmission optimization channel data refers to transmission optimization channels configured for different SaaS service data to be accessed, for example, the transmission optimization channel data configured for the SaaS service to be accessed with the access domain name of a.com is an optimization channel 1, the transmission optimization channel data configured for the SaaS service to be accessed with the access domain name of b.com is an optimization channel 2, and the like. As shown in fig. 6, fig. 6 is a graph of the relationship between domain names and transmission optimized channels and egress routers. According to the user demand, the transmission optimization channel with the domain name of a.com is set as an optimization channel 1, the transmission optimization channel with the domain name of b.com is set as an optimization channel 2, and the transmission optimization channels of other domain names can be set according to the user demand.

Step S13: setting a transmission optimization channel corresponding to the SaaS service to be accessed in the original transmission optimization channel data based on the domain name of the SaaS service to be accessed.
After obtaining the domain name of the SaaS service to be accessed, a transmission optimization channel corresponding to the SaaS service to be accessed can be set in the original transmission optimization channel data according to the domain name of the SaaS service to be accessed, the transmission optimization channel corresponding to the SaaS service to be accessed can be set according to the user requirement, for example, the transmission optimization channel with the domain name of a.com is set as an optimization channel 1, the transmission optimization channel with the domain name of b.com is set as an optimization channel 2, and the like, so that the transmission optimization channels corresponding to the domain names are set according to the user requirement.
Step S14: and establishing a second mapping relation between the domain name of the SaaS service to be accessed and the transmission optimization channel.
