Description

Method and device for improving cache spitting flow, computing equipment and storage medium

Technical Field

The invention relates to the technical field of Internet HTTP (hyper text transport protocol), in particular to a method and a device for improving cache spitting flow, computing equipment and a storage medium.

Background

With the development of the internet in recent years, the number of internet users, the application types of the internet, the network bandwidth and the like all show explosive growth, and have great influence on the society and the lives of people. In the next 5 years, the internet traffic in China increases by more than 40% each year, and in contrast, although broadband construction also increases, the service traffic has increased far beyond the speed of bandwidth increase, and the existing bandwidth and the visible increase in the future are far from meeting the phagocytosis of the network bandwidth by the application of large-traffic continuous occupied bandwidth.

In order to respond to the challenge of rapid increase of Internet traffic, mainstream operators around the world start to build a CDN/Cache network, and the purpose of the CDN/Cache network is to add a new network architecture to the existing Internet, and publish the content of a website to the "edge" of the network closest to a user, so that the user can obtain the required content nearby, thereby solving the problem of congestion of the Internet network, improving the response speed of the user accessing the website, and solving the problem of slow response speed of the user accessing the website due to small network bandwidth, large user access amount, uneven website distribution, and the like.

In the Cache network flow guiding, Local DNS forwards domain name query of a user terminal to a Cache network in a DNS forwarding mode, and the Cache network provides service for users and improves response speed. For large network operators such as China Mobile, the types of access services of users are rich, and Cache acceleration needs to be performed on hot spot services. The existing Cache operation method mainly utilizes DNS log data to inquire domain names with a large DNS resolution amount of users, adds the domain names into a Cache network, and provides acceleration service for the service domain names. DNS log data can only provide times for analyzing different domain names by a user DNS, and the method can not accurately capture large-flow domain name services of the user and provide acceleration service for hot spot services of the user when a Cache network is operated.

In the hot spot confirmation, the DNS log data counts the DNS process of each user, that is, the source IP of the initiating user requests a domain name and a resolved address, and the statistics of these data can only calculate the DNS resolution times of each domain name. After initiating the DNS resolution to obtain the server IP, the user interacts with the server through the HTTP protocol to obtain the access content, so the DNS resolution times cannot represent that the service is a hotspot service.

The proposal utilizes the field in the HTTP protocol to capture the domain name with large flow, and combines the DNS log and the cacheable analysis to perform cache acceleration processing on the host in the cache white list. Fig. 1 is a schematic flow chart of a method for increasing cache spitting traffic according to an embodiment of the present invention.

As shown in fig. 1, in step S100, a full-user HTTP ticket may be generated based on HTTP headers, where the full-user HTTP ticket includes content lengths and host identification information extracted from each HTTP header.

The content length is the length of the content in the message except the header. The HTTP message comprises an uplink message, namely a request message, and a downlink message, namely a response message, the HTTP request message comprises a request method, a request URL, an HTTP protocol and version, a message header and a message body, and the HTTP response message comprises a message protocol and version, a state code and state description, a response header and a response body. The HTTP message header comprises Cache-Control, Content-Type, Content-Length, Content-Charset, Port, Host and the like, and field information such as Content Length-Length, Host and the like can be extracted from the HTTP message header to generate a full-user HTTP ticket, wherein the HTTP ticket is recorded information of HTTP access requests of all users in a certain area. Wherein, the host can be IP, port number or domain name.

According to an embodiment of the present invention, the HTTP message of the user can be obtained by analyzing the deep analysis message data.

The DPI deep analysis message can complete analysis, protocol identification and content identification of the user data message by identifying and analyzing uplink and downlink data packets of the user, and obtain valuable information such as a destination URL (uniform resource locator). And may match control rules based on identified traffic classes or parsed keywords.

According to an embodiment of the invention, the user HTTP message may be identified by the probe device. For example, message recognition may be performed using a probe device TMA (tower mounted amplifier) that is in series on the metro network egress link.

According to an embodiment of the invention, the message header corresponding to the HTTP message successfully analyzed can be imported into a ticket acquisition system to generate a full amount of user HTTP tickets, and the HTTP message unsuccessfully analyzed can be attributed to junk data.

The call ticket collection system can be realized by using C # language and FTP downloading, and can collect port data in real time.

According to an embodiment of the invention, the identified HTTP message can be transmitted to the call ticket collection server through the port mirror image, so that the convergence of the request message and the response message is realized.

The port mirror image is to copy a message of a designated port (source port), vlan (source vlan) or CPU to another port (destination port), the destination port can be connected to the data monitoring device, and the data monitoring device can analyze the message copied to the destination port, so that the request message and the response message can be gathered. Network monitoring and troubleshooting can also be performed, for example, if the B port is a mirror image of the a port, the network data packet of the a port can be acquired on the B port through some common tools, and whether abnormal network traffic exists on the a port can be analyzed through the acquired data packet.

According to an embodiment of the invention, a data table taking the data stream ID of each user HTTP access process as a row and the field extracted from the HTTP message header as a column can be used as a full-user HTTP ticket. The request and response in the HTTP access process, and the data read/write operation on the network can be completed using data streams.

The HTTP ticket is a session level detail record of a signaling process and a service transmission process generated after processing based on the internet full data, and includes all internet access information of a user, which may include quintuple information, HTTP message information, and the like.

Fig. 2 is a schematic diagram illustrating a full-user HTTP ticket according to an embodiment of the present invention. As shown in fig. 2, fields such as a website name, a Host, a PORT, and a total number of URLs may be extracted, data streams generated in one HTTP process initiated by the same user may be named as ID 1, data streams for all users in a certain area are listed in sequence, and a data table with data stream IDs as rows and extracted HTTP fields as columns is generated.

As shown in fig. 1, in step S200, the content lengths of the same host may be summed based on the HTTP tickets of all users, so as to obtain the total content length of each host.

For example, HTTP tickets can be uploaded to a data processing system in an FTP manner with day as granularity, and the total content length of each host can be obtained by performing summation operation on content-lengths of different data stream IDs belonging to the same host field, and can be used as a basis for traffic sequencing.

In step S300, the total content lengths may be sorted by taking the host as a granularity, and the hot spot traffic host is determined. Fig. 3 shows a schematic diagram of traffic ordering for domain name dimension according to an embodiment of the invention.

According to an embodiment of the invention, the total content length can be arranged in a descending order, the first N hosts are used as hot spot flow hosts, and N is the number of cacheable hosts estimated by combining the network service capability of the cache.

For example, according to the network service capability, N may be a ratio of the number of system design connections to the average number of connections per domain name, and topN hosts are selected as the hotspot traffic hosts.

In step S400, cache acceleration processing may be performed on the hotspot traffic host.

According to an embodiment of the present invention, the present province rate of each hot traffic host may be determined in combination with the DNS log, the hot traffic host whose present province rate is smaller than the predetermined threshold is added to the cache white list, the hot traffic host whose present province rate is not smaller than the predetermined threshold is added to the cache black list, and cache acceleration processing is performed on the hosts in the cache white list.

The provincial rate may be a ratio of the number of times that the user DNS resolves to the province to the total number of times that the user DNS resolves.

For example, the attribution of the hot spot traffic host is judged, and if the province rate > is 50%, the host attribution is province; if the province rate is less than 50%, the host belongs to the province. Because the Cache cannot accelerate the in-provincial resources, the Cache blacklist is added if the host is the in-provincial resources, and the Cache whitelist is added if the host is the out-of-provincial resources.

According to an embodiment of the present invention, a port may be extracted from each HTTP packet header, cacheability of a hot traffic host is determined according to port information, and a hot traffic host having a port 80 proportion of 100% is added to a cache white list, and/or a hot traffic host having a port 80 proportion of not 100% is added to a cache black list.

For example, since the Cache network only serves resources with port 80, if the proportion of the port 80 under the host is 100%, the Cache white list is added, otherwise, the Cache black list is added.

Fig. 4 shows a schematic flow diagram of a provincial large flow domain name cache according to an embodiment of the invention. As shown in fig. 4, a DPI is used to capture uplink and downlink messages of a user, a successfully captured paired HTTP message header is imported into a call ticket collection system, and a unsuccessfully captured paired HTTP message header is used as spam data. Extracting fields needing to be reserved in an HTTP message header, wherein the fields comprise content-length/host/cache-control/port and the like, and taking the HTTP message with unsuccessful extraction as junk data. And acquiring a hot spot flow host, and performing summation operation on content-length belonging to the same host to obtain flow sequencing taking the host as granularity, namely accurately capturing the hot spot flow host and not processing non-hot spot flow hosts. And judging the analysis attribution of the host, adding a cache blacklist if the host is an intra-province resource, and adding a cache whitelist if the host is an extraprovince resource. And judging the cacheability of the host, if the ratio of the port under the host to 80 is 100%, adding a cache white list, and if not, adding a cache black list.
