Detailed Description
At present, the second generation internet IPv4 (internet protocol version 4) technology has limited network address resources, which seriously affects the application and development of the internet in various regions, and the IPv4 technology can only realize man-machine conversation. The address capacity of the IPv6 technology is far greater than that of the IPv4 technology, which not only solves the problem of the number of network address resources, but also clears obstacles on the limit of the number of devices connected to the internet except computers, and furthermore, the IPv6 technology can be extended to conversations of non-computer things. Therefore, aiming at the defects of uneven address distribution and poor continuity of the IPv4 address of the IPv4 protocol in the prior art, the present disclosure provides a method and an apparatus for scheduling a traffic entry based on the IPv6 (internet protocol version 6) protocol, so as to facilitate users in different regions to access a website server to obtain content, so as to solve the problem that the service quality of the website server is affected due to the fact that the speeds of accessing servers deployed in different regions are very different when the network environments used by users in different regions are different.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
In an aspect of the present disclosure, a method for scheduling a traffic entry based on an IPv6 protocol is provided, fig. 1 is a schematic step diagram of a method for scheduling a traffic entry based on an IPv6 protocol according to an embodiment of the present disclosure, and fig. 2 is a schematic flow diagram of a method for scheduling a traffic entry based on an IPv6 protocol according to an embodiment of the present disclosure, as shown in fig. 1 and fig. 2, the method includes:
step S1, dividing each IPv6 address into at least one address field, wherein each address field corresponds to a region;
the IPv6 address is composed of a 128-bit binary, with 8 fields, each field having 4 characters. Generally, the first three segments represent the divisions of the territory. Therefore, the method divides the first three sections of the IPv6 address according to different values, divides each IPv6 address to obtain at least one address section, and corresponds each address section to a region. Based on the characteristics of the IPv6 address, the geographic positions of adjacent IPv6 addresses in the same region are not far away. In addition, each territory typically has an access mechanism for assigning IPv6 addresses to other servers or non-computer objects in the territory. As defined in RFC 1881(IPv6 address allocation management), IANA (internet assigned numbers authority) assigns IPv6 address segments to regional or other types of access agencies which in turn assign smaller address segments to network providers or other sub-access agencies which in turn assign addresses to other organizations such as business companies, individuals, etc. requesting IPv6 addresses.
Therefore, based on the distribution principle of the IPv6 address, the access mechanism of the address can be determined according to the first 3 segments of the IPv6 address, and the region of the access mechanism is queried, so that the region can be determined, and a data table of the region corresponding to the IPv6 address can be created by using the data.
Furthermore, data units of IPv6 addresses corresponding to website servers and cache servers in various regions can be established, so that the IPv6 address of the website and the cached IPv6 address can be obtained more conveniently;
step S2, at least one cache server is arranged in each region, and the cache IPv6 address of each cache server is obtained;
in order to reduce the access traffic pressure of a target website and the time spent by a user when accessing a website server, at least one cache server is arranged in each region for caching data, and the cache IPv6 address of each cache server is also obtained in advance, so that the subsequent user can directly access the cache server conveniently.
S3, acquiring the IPv6 address of the website server accessed by the user according to the domain name accessed by the user;
generally, a user inputs a domain name of a website to be accessed, and a computer acquires an IPv6 address of a website server corresponding to the domain name through domain name resolution.
Step S4, judging whether the access content of the user is cached in a cache server of a region corresponding to the local IPv6 address of the user: if the access content of the user is cached in a cache server in a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the cache IPv6 address of the cache server; if the access content of the user is not cached in a cache server of a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the website IPv6 address of the website server, acquiring the access content, and caching the access content into at least one cache server in the region corresponding to the local IPv6 address;
the flow inlet scheduling method based on the IPv6 protocol can be based on a cloud platform, the cloud platform can adopt OpenStack technology, and DNS (domain name system) scheduling service is provided. When a user surfs the internet through a browser, the user needs to access a DNS to analyze a domain name, the DNS is used for scheduling multi-activity deployed applications and contents, the domain name analysis IPv6 addresses are classified according to the scale of the content type, and the flow is optimally scheduled by referring to the geographic position and the service quality of the IPv6 address. The scheduling strategy is as follows: and the local cache of the access content reduces the flow of accessing the original website server, saves the bandwidth cost of the website, and improves the service quality and the service availability of the website.
More specifically, first, in a cache server of a region corresponding to the local IPv6 address of the user itself, it is searched whether or not access content that the user needs to access is cached.
And if the access content is a video file, transmitting the access content in a segmented distribution mode. The video file is the video streaming media content with large flow. The streaming media has no requirement on the integrity of the edge content, and the cache node can push the content in real time only by storing a small number of programs or program segments, so that complete service is provided for users. When the content requested by the user is only partial or none, the system adopts the distribution technology to carry out rapid distribution of the content.
If the access content is a picture file, transmitting the access content in a partial distribution mode. The picture files are content with medium flow scale, the hit rate of the edge system can be improved by partial distribution technology, if 10% of the content is fully copied, 20% of the content is copied by 50% and 50% of the content is copied by 10%, the system can achieve the hit rate of more than 95%, the load of a backbone network is greatly reduced, and the distribution performance is excellent.
If the access content is a text file, all distribution modes are adopted for transmission. The text file is the content with small flow scale, the complete content is cached to the local node by adopting the whole distribution technology, and the user can directly access and obtain the complete content.
And if the access content of the user is cached in a cache server in a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the cache IPv6 address of the cache server. And when the user accesses the cache server, the priority of the cache server in the busy state is set to be low, and the priority of the cache server in the idle state is set to be high.
That is, when the access content of the user is cached in the cache server in the region corresponding to the local IPv6 address of the user, the busy/idle state of the cache server is determined, and then the cache IPv6 address of the idle cache server is set as the access IPv6 address of the user, and the idle cache server is preferably used for the user to access.
Furthermore, when the cache servers in the region where the user is located are all in a busy state, the access IPv6 address of the user is set as the service IPv6 address of any cache server capable of normally providing service. That is to say, the cache server capable of providing services normally can be randomly selected, and the IPv6 address of the cache server can be set as the access IPv6 address of the user, so that the cache server can provide better access for the user, and the situations that the cache server is abnormally shut down and has too long waiting time and cannot be transmitted are avoided.
If the access content of the user is not cached in a cache server in a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the website IPv6 address of the website server, acquiring the access content, and caching the access content into at least one cache server in a region corresponding to the local IPv6 address. In some embodiments, the access content may also be cached in all cache servers in the domain corresponding to the local IPv6 address, so that when a user in the domain corresponding to the local IPv6 address accesses the access content, the access content may be obtained from any cache server in the domain.
That is, when the access content of the user is not cached in the cache server, the access IPv6 address of the user is set as the website IPv6 address of the website server, and after the user acquires the access content, the access content is cached in at least one idle cache server in a region corresponding to the user, so that adverse effects caused when only one cache server is available and the cache server cannot work normally are prevented.
In this process, when the user accesses the cache server, the priority of the cache server in the busy state is set to be low, and the priority of the cache server in the idle state is set to be high. After that, when the cache server caches the access content, the cache server having a high priority preferentially caches the access content. Furthermore, when the cache servers are all in a busy state, the access IPv6 address of the user is set to be the service IPv6 address of any cache server capable of providing services normally, that is, the cache server capable of providing services normally can be selected randomly, and the IPv6 address of the cache server is set to be the access IPv6 address of the user, so that the cache server can provide better access for the user, and the problems that the cache server is abnormally shut down and the like, so that the waiting time is too long and transmission is not possible are avoided.
In another aspect of the embodiments of the present disclosure, a scheduling apparatus for a traffic entry based on an IPv6 protocol is further provided, fig. 3 is a schematic structural diagram of the scheduling apparatus for a traffic entry based on an IPv6 protocol in the embodiments of the present disclosure, and as shown in fig. 3, the apparatus includes a partitioning module, a DNS resolution module, and an IPv6 address scheduling and allocating module.
The dividing module is used for dividing each IPv6 address into at least one address segment, each address segment corresponds to a region, each region at least has one cache server for caching data, and each cache server corresponds to a cache server IPv6 address.
Based on the distribution principle of the IPv6 address, the access mechanism of the address can be determined according to the first 3 segments of the IPv6 address, and the region of the access mechanism is inquired, so that the region can be determined, and a region data table corresponding to the IPv6 address can be created by using the data.
In addition, in order to reduce the pressure of website access traffic and the time spent by the user in accessing the website server, at least one cache server is arranged in each region for caching data, and the cache IPv6 address of each cache server is also obtained in advance, so that the subsequent user can directly access the cache server conveniently.
Further, the dividing module may further include a data unit including IPv6 addresses corresponding to the web server and the cache server in each region, through which the cache IPv6 address and the cache IPv6 address can be conveniently acquired.
The DNS analysis module is used for acquiring the IPv6 address of the website server accessed by the user according to the domain name accessed by the user;
generally, a user inputs a domain name of an access website to be accessed, and a computer first obtains the IPv6 address of the website server corresponding to the domain name.
An IPv6 address scheduling and allocating module, configured to determine whether access content of a user is cached in a cache server in a region corresponding to a local IPv6 address of the user: if the access content of the user is cached in a cache server in a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the cache IPv6 address of the cache server; if the access content of the user is not cached in a cache server in a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the website IPv6 address of the website server, acquiring the access content, and caching the access content into at least one cache server in a region corresponding to the local IPv6 address.
The traffic inlet scheduling device based on the IPv6 protocol may be based on a cloud platform, and the cloud platform may employ an OpenStack technology. When a user surfs the internet through a browser, the user needs to access a DNS to analyze a domain name, the DNS is used for scheduling multi-activity deployed applications and contents, the domain name analysis IPv6 is classified according to the scale of the content type, and the flow is optimally scheduled by referring to the geographical position and the service quality of IPv 6. The scheduling strategy is as follows: and the local cache of the access content reduces the flow of accessing the original website server, saves the bandwidth cost of the website, and improves the service quality and the service availability of the website.
More specifically, first, in a cache server of a region corresponding to the local IPv6 address of the user itself, it is searched whether or not access content that the user needs to access is cached.
According to the type of the access content, different transmission modes are adopted so as to achieve a more efficient transmission effect. If the access content is a video file, transmitting the access content in a segmented distribution mode; if the access content is a picture file, transmitting the access content in a partial distribution mode; if the access content is a text file, all distribution modes are adopted for transmission.
And if the access content of the user is cached in a cache server in a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the cache IPv6 address of the cache server. And when the user accesses the cache server, the priority of the cache server in the busy state is set to be low, and the priority of the cache server in the idle state is set to be high. That is, when the access content of the user is cached in the cache server in the region corresponding to the local IPv6 address of the user, the busy/idle state of the cache server is determined, and then the cache IPv6 address of the idle cache server is set as the access IPv6 address of the user, and the idle cache server is preferably used for the user to access.
Furthermore, when the cache servers in the region where the user is located are all in a busy state, the access IPv6 address of the user is set as the service IPv6 address of any cache server capable of normally providing service. That is to say, the cache server capable of providing services normally can be randomly selected, and the IPv6 address of the cache server can be set as the access IPv6 address of the user, so that the cache server can provide better access for the user, and the situations that the cache server is abnormally shut down and has too long waiting time and cannot be transmitted are avoided.
If the access content of the user is not cached in a cache server in a region corresponding to the local IPv6 address of the user, setting the access IPv6 address of the user as the website IPv6 address of the website server, acquiring the access content, and caching the access content into at least one cache server in a region corresponding to the local IPv6 address. That is, when the access content of the user is not cached in the cache server, the access IPv6 address of the user is set as the website IPv6 address of the website server, and after the user acquires the access content, the access content is cached in at least one idle cache server in a region corresponding to the user, so that adverse effects caused when only one cache server is available and the cache server cannot work normally are prevented. In some embodiments, the access content may also be cached in all cache servers in the domain corresponding to the local IPv6 address, so that when a user in the domain corresponding to the local IPv6 address accesses the access content, the access content may be obtained from any cache server in the domain. In this process, when the user accesses the cache server, the priority of the cache server in the busy state is set to be low, and the priority of the cache server in the idle state is set to be high. After that, when the cache server caches the access content, the cache server having a high priority preferentially caches the access content. Furthermore, when the cache servers are all in a busy state, the access IPv6 address of the user is set to be the service IPv6 address of any cache server capable of providing services normally, that is, the cache server capable of providing services normally can be selected randomly, and the IPv6 address of the cache server is set to be the access IPv6 address of the user, so that the cache server can provide better access for the user, and the problems that the cache server is abnormally shut down and the like, so that the waiting time is too long and transmission is not possible are avoided.
