Description
Technical Field
The invention relates to the field of QUIC message processing, in particular to a QUIC message processing method, a QUIC message processing device, a readable storage medium and gateway equipment.
Background
The WEB Protocol has undergone the evolution from HTTP1.0 to HTTP3, wherein the H3 (short for HTTP 3) Protocol has changed greatly, and the transport layer Protocol is not based on TCP (Transmission Control Protocol) any more, but is changed to a QUIC (fast UDP Internet Connection Protocol) Protocol based on UDP (User Datagram Protocol). The QUIC protocol realizes reliable transmission, solves the problem of head-of-line blocking, supports connection migration and flexible congestion control, and realizes the establishment of 0-RTT (Round-Trip Time) connection based on TLS1.3 (transport layer security protocol 1.3, english full name TransportLayerSecurity 1.3). The QUIC protocol has various characteristics, obviously improves the network transmission quality and is very suitable for the acceleration scene of a near-customer edge network. For example, a CDN (Content Delivery Network, which is an intelligent virtual Network built on the basis of an existing Network, depends on edge servers deployed in various places, and enables a user to obtain required Content nearby through functional modules of load balancing, content distribution, scheduling and the like of a central platform, so as to reduce Network congestion and improve user access response speed and hit rate) is an acceleration product in a cloud scenario, and the access experience of an actual user can be improved by significantly reducing client edge access delay through the QUIC protocol upgrade.
However, there are two major versions of the QUIC protocol in its development: gQUIC and iQUIC. Currently, existing gateway devices (e.g., CDN ingress gateways) all choose a standard implementation, and it is difficult to support both protocols simultaneously. Although the gQUIC protocol stack with a high version can be compatible with the two protocols, the use of the transplanted gQUIC protocol stack for processing the iQUIC message results in poor flexibility and efficiency and higher maintenance cost.
Therefore, the gateway device in the related art has a problem that it is incompatible or poorly compatible with different types of QUIC protocols, and no effective solution has been proposed so far.
The above information disclosed in the background section is only for enhancement of understanding of the background of the technology described herein. The background art may therefore contain certain information that does not form the known prior art to those skilled in the art.

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
It should be noted that the terms "first", "second", and the like in the description and claims of the present invention and the accompanying drawings are used for distinguishing different objects, and are not used for limiting a specific order.
Fig. 1 is a QUIC message processing method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, receiving a QUIC message from a target terminal device;
step S104, analyzing the QUIC message, and determining the type of the QUIC protocol to which the QUIC message belongs;
and step S106, processing the QUIC message by using a corresponding QUIC protocol stack according to the type of the QUIC protocol to which the QUIC message belongs.
By adopting the QUIC message processing method of the scheme, after the QUIC message from the target terminal equipment is received; and analyzing the QUIC message, determining the QUIC protocol type of the QUIC message according to the analysis result of the QUIC message, and processing the QUIC message by using a corresponding QUIC protocol stack according to the QUIC protocol type of the QUIC message. Therefore, after receiving messages with different protocol types, the QUIC protocol types of the messages can be identified and distributed to the corresponding QUIC protocol stacks for processing, so that the QUIC message processing method can simultaneously support multiple different types of QUIC protocols, and can process the messages with the corresponding protocol types through the corresponding protocol stacks more flexibly and efficiently, and has good compatibility with the different types of QUIC messages. For example, whether the QUIC message belongs to the gQUIC protocol or the iQUIC protocol can be distinguished, and of course, the method is also applicable to other types of QUIC protocols. The QUIC message processing method can solve the problem that gateway equipment in the related technology is incompatible or poor in compatible effect on different types of QUIC protocols, and effectively improves the universality of gateway products.
The target end device may be any type of networked device, among others. A Protocol stack, also called Protocol stack, is a specific software implementation of a computer network Protocol suite, and the Protocol stack is different for different types of QUIC protocols.
As described above, the determination of the QUIC protocol type to which the QUIC message belongs is based on the analysis result of the QUIC message, and in order to more accurately determine the QUIC protocol to which the QUIC message belongs based on the analysis result of the QUIC message, in this embodiment, the analyzing the QUIC message and the determining of the QUIC protocol type to which the QUIC message belongs includes: analyzing the QUIC message to obtain message attribute information; and determining the QUIC protocol type of the QUIC message according to the message attribute information.
In practical implementation, the message attribute information is information representing the attribute of the QUIC message itself, and is required to be able to determine the QUIC protocol type of the QUIC message, and specifically, it may include various information. For example, in this embodiment, the message attribute information includes the first byte of the QUIC message; after the QUIC message is analyzed to obtain message attribute information (including the first byte of the QUIC message), determining the type of the QUIC protocol to which the QUIC message belongs according to the message attribute information comprises the following steps: determining whether the QUIC message is a long message or a short message according to the first byte; and under the condition that the QUIC message is not a long-short message, determining that the type of the QUIC protocol to which the QUIC message belongs is a gQUIC protocol.
The first byte of the QUIC message is the first byte of the QUIC message, which is the first 8 bits of the head of each QUIC message, can be directly extracted from the QUIC message, and can judge whether the message is a long message or a short message according to the bits. The long and short messages refer to that the format of the message is a long message or a short message, and the message belongs to the long and short messages as long as the format of the message is one of the long message and the short message. For two mainstream gQUIC protocols and iQUIC protocols, the iQUIC protocol always adopts a format of a long and short message, and the gQUIC protocol only follows the format of the long and short message in a Q043 version and later versions. In this embodiment, whether the QUIC message is a long-short message or not can be determined according to the first byte of the message, considering that the gQUIC protocol and the iQUIC protocol are most commonly used, if the QUIC message is not in the format of the long-short message, the protocol to which the QUIC message belongs is temporarily determined as the version before Q043 of the gQUIC protocol, so that the type of the QUIC protocol to which the QUIC message belongs is determined as the gQUIC protocol, and then the gQUIC protocol is transferred to the protocol stack of the gQUIC for processing. Therefore, screening and processing of a part of QUIC messages are conveniently realized. Of course, the determination result that the QUIC message is determined to be the gQUIC message by determining that the QUIC message is not a long or short message is a temporary determination result, and the determination result is accurate in the case of only considering the gQUIC protocol and the iQUIC protocol, and needs to be further verified in the case of other protocols.
After the QUIC message is subjected to the judgment and the shunting processing, if the QUIC protocol type of the QUIC message is determined to be the gQUIC protocol, the processing of the QUIC message by using the corresponding QUIC protocol stack according to the QUIC protocol type of the QUIC message comprises the following steps: and processing the QUIC message by using a gQUIC protocol stack. As described above, the determination result that the QUIC packet protocol that is determined not to be the long and short packet type is the gQUIC protocol is a temporary determination result, and in the case that the protocol includes both the gQUIC protocol and the iQUIC protocol, it is determined that an error may occur, and therefore, when the gQUIC packet is processed by the gQUIC protocol stack, a processing failure may occur, and at this time, the packet may be damaged or the determination error of the protocol to which the packet belongs (i.e., the packet does not belong to the gQUIC protocol) may occur, and in the case that the gQUIC packet is processed by the gQUIC protocol stack, the QUIC packet may be determined to be an abnormal packet. Therefore, on the basis of conveniently realizing the message type judgment and the shunt processing, abnormal messages can be found in time, and the reliability of QUIC message processing can be effectively improved.
After judging whether the QUIC message is a long-short message or not by adopting the first byte of the QUIC message, if the QUIC message is the long-short message, the type of the QUIC protocol to which the QUIC message belongs can not be directly determined, and under the condition, the determination of the type of the QUIC protocol to which the QUIC message belongs according to the message attribute information comprises the following steps: determining the message type of the QUIC message, wherein the message type is a long message or a short message; acquiring protocol type judgment information from the QUIC message according to the message type; and determining the QUIC protocol type of the QUIC message according to the protocol type judgment information. That is, under the condition that it is determined that the QUIC message is a long or short message, the specific type of the QUIC message is further determined, that is, whether the QUIC message is a long message or a short message is determined, which is very easy to implement in the field, after the specific message type is determined, corresponding protocol type determination information is extracted from the QUIC message according to different message types, that is, the protocol type determination information is extracted differently according to different message types, so that it is ensured that the extracted protocol type determination information can be used for accurately determining the QUIC protocol type to which the QUIC message belongs.
Specifically, after the above message type determination is made, the following two situations may occur:
for the first case, the message type is a long message, and at this time, the protocol type judgment information includes protocol version information; determining the QUIC protocol type of the QUIC message according to the protocol type judgment information comprises the following steps: and determining the QUIC protocol type of the QUIC message according to the protocol version information. That is, after determining that the message type is a long message, the protocol version information is extracted from the QUIC message, and according to the specific format of the long message, the protocol version information is recorded in a specific field, so that on the basis of knowing that the message is a long message, the protocol version information can be easily extracted, and according to the protocol version information, the QUIC protocol type to which the message belongs can be conveniently determined.
For the second case, the message type is a short message, and at this time, the protocol type judgment information includes target connection ID information; determining the QUIC protocol type of the QUIC message according to the protocol type judgment information comprises the following steps: acquiring a session table of an iQUIC protocol stack; searching target connection ID information from a session table; under the condition that the target connection ID information is found, determining that the QUIC protocol type of the QUIC message is an iQUIC protocol; and under the condition that the target connection ID information is not found, determining that the QUIC protocol type of the QUIC message is a gQUIC protocol. That is, after determining that the packet type is a short packet, the method is different from the above-mentioned long packet processing method, specifically, the short packet is encrypted and cannot be viewed in plaintext, so that the processing cannot be performed by the above-mentioned method for processing the long packet. The QUIC connection process of the iQUIC protocol is further explained here: initiating a handshake message for the first time, similar to tcp handshake, and the difference is that the QUIC is not based on a quadruplet but based on a DCID as a connection identifier, after connection, session information is established and stored in the server, and the corresponding DCID is also stored in a session table in an iQUIC protocol stack, where the session table is a session table. Under the condition that the message type of the QUIC message is determined to be a short message, in order to further judge whether the QUIC message belongs to a gQUIC protocol or an iQUIC protocol, a DCID is extracted from the QUIC message, the DCID is information which can be directly obtained, after the DCID of the QUIC message is taken, the DCID is searched from a session table of an iQUIC protocol stack, if the DCID is searched, the situation that the iQUIC message with the same connection exists before is shown, the protocol type of the new QUIC message is determined to be the iQUIC protocol, if the DCID is not searched, the protocol type of the QUIC message is determined to be the gQUIC protocol, because the corresponding DCID is stored in the session table only when the iQUIC protocol is connected for the first time, and the gQUIC protocol does not perform the processing. Therefore, the specific protocol type of the QUIC short message can be conveniently and accurately determined by the mode of searching the DCID in the session table of the iQUIC protocol stack.
As shown in fig. 3, after the QUIC message processing method described above is used, the same VIP can be used: the PORT monitors different types of QUIC messages (gQUIC messages and iQUIC messages), for example, after the gQUIC messages and the iQUIC messages enter the gateway device with an IP of 127.0.0.1 through a 443 PORT, the above-mentioned QUIC message processing method is executed through a protocol splitter (a piece of software running on the gateway), so as to determine the protocol type of each QUIC message, and further distribute the protocol type to a corresponding protocol stack (gQUIC protocol stack or iQUIC protocol stack). The QUIC message processing method can solve the problem that the gateway equipment in the prior art cannot simultaneously support different types of QUIC protocols, and effectively improves the universality of gateway products.
Secondly, as shown in fig. 2, according to an embodiment of the present invention, there is also provided a QUIC message processing apparatus, including: the receiving unit is used for receiving the QUIC message from the target terminal equipment; the analysis unit is used for analyzing the QUIC message and determining the type of the QUIC protocol to which the QUIC message belongs; and the processing unit is used for processing the QUIC message by using a corresponding QUIC protocol stack according to the type of the QUIC protocol to which the QUIC message belongs.
The QUIC message processing device of the embodiment of the invention receives the QUIC message from the target terminal equipment by the receiving unit; the analysis unit analyzes the QUIC message, determines the QUIC protocol type of the QUIC message according to the analysis result of the QUIC message, and the processing unit further uses the corresponding QUIC protocol stack to process the QUIC message according to the QUIC protocol type of the QUIC message. Therefore, after receiving messages with different protocol types, the QUIC protocol types of the messages can be identified and distributed to the corresponding QUIC protocol stacks for processing, so that the QUIC message processing method can simultaneously support multiple different types of QUIC protocols, and can process the messages with the corresponding protocol types through the corresponding protocol stacks more flexibly and efficiently, and has good compatibility with the different types of QUIC messages. For example, whether the QUIC message belongs to the gQUIC protocol or the iQUIC protocol can be distinguished, and of course, the method is also applicable to other types of QUIC protocols. The QUIC message processing method can solve the problem that gateway equipment in the related technology is incompatible or poor in compatible effect to different types of QUIC protocols, and effectively improves the universality of gateway products.
The target end device may be any type of networked device, among others. A Protocol stack, also called Protocol stack, is a specific software implementation of a computer network Protocol suite, and the Protocol stack is different for different types of QUIC protocols.
As described above, the basis for determining the type of the QUIC protocol to which the QUIC message belongs is the analysis result of the QUIC message, and in order to more accurately determine the QUIC protocol to which the QUIC message belongs based on the analysis result of the QUIC message, in this embodiment, the analysis unit includes: the analysis module is used for analyzing the QUIC message to obtain message attribute information; and the first determining module is used for determining the QUIC protocol type of the QUIC message according to the message attribute information. In practical implementation, the message attribute information is information representing the attribute of the QUIC message itself, and it is required to be able to determine the QUIC protocol type to which the QUIC message belongs, and specifically, it may include various information. For example, in this embodiment, the message attribute information includes the first byte of the QUIC message; the first determining module includes: the first determining submodule is used for determining whether the QUIC message is a long message or a short message according to the first byte; and the second determining submodule is used for determining that the type of the QUIC protocol to which the QUIC message belongs is the gQUIC protocol under the condition that the QUIC message is not a long-short message. The first byte of the QUIC message, namely the first byte of the QUIC message, is the first 8 bits of the head byte of each QUIC message, can be directly extracted from the QUIC message, and can judge whether the message is a long message or a short message according to the bit. The long and short messages refer to that the format of the message is a long message or a short message, and the message belongs to the long and short messages as long as the format of the message is one of the long message and the short message. For two mainstream gQUIC protocols and iQUIC protocols, the iQUIC protocol always adopts the format of a long and short message, and the gQUIC protocol only follows the format of the long and short message in the Q043 version and later versions. In this embodiment, the first determining module may determine whether the QUIC packet is a long or short packet according to a first byte of the packet, and if the QUIC packet is not in the format of the long or short packet, the first determining module may determine the protocol to which the QUIC packet belongs as a version before Q043 of the gQUIC protocol, determine the QUIC protocol to which the QUIC packet belongs as the gQUIC protocol, and then transfer the gQUIC protocol to a protocol stack of the gQUIC for processing.
The processing unit includes: the processing module is used for processing the QUIC message by using a gQUIC protocol stack under the condition that the type of the QUIC protocol to which the QUIC message belongs is determined to be the gQUIC protocol; and the second determining module is used for determining the QUIC message as an abnormal message under the condition that the gQUIC protocol stack fails to process the QUIC message. If the QUIC protocol type of the QUIC message is determined to be the gQUIC protocol, the gQUIC protocol stack is used for processing the QUIC message; when the gQUIC protocol stack processes the QUIC message, the situation of processing failure may occur, at this time, the message may be damaged or the protocol determination of the message is wrong, and when the gQUIC protocol stack fails to process the QUIC message, the QUIC message is determined to be an abnormal message. Therefore, on the basis of conveniently realizing the message type judgment and the shunt processing, abnormal messages can be found in time, and the reliability of QUIC message processing can be effectively improved.
After judging whether the QUIC message is a long-short message or not by adopting the first byte of the QUIC message, if the QUIC message is the long-short message, the type of the QUIC protocol to which the QUIC message belongs can not be directly determined, and in this case, the first determining module comprises: the third determining submodule is used for determining the message type of the QUIC message under the condition that the QUIC message is a long message or a short message; the acquisition submodule is used for acquiring protocol type judgment information from the QUIC message according to the message type; and the fourth determining submodule is used for determining the QUIC protocol type of the QUIC message according to the protocol type judging information. That is, under the condition that it is determined that the QUIC message is a long or short message, the specific type of the QUIC message is further determined, that is, whether the QUIC message is a long message or a short message is determined, which is very easy to implement in the field, after the specific message type is determined, corresponding protocol type determination information is extracted from the QUIC message according to different message types, that is, the protocol type determination information is extracted differently according to different message types, so that it is ensured that the extracted protocol type determination information can be used for accurately determining the QUIC protocol type to which the QUIC message belongs.
Specifically, after the above message type determination is made, the following two situations may occur:
under the condition that the message type is a long message, the protocol type judgment information comprises protocol version information; and the fourth determining submodule is used for determining the QUIC protocol type of the QUIC message according to the protocol version information. That is, after determining that the message type is a long message, the protocol version information is extracted from the QUIC message, and according to the specific format of the long message, the protocol version information is recorded in a specific field, so that on the basis of knowing that the message is a long message, the protocol version information can be easily extracted, and according to the protocol version information, the QUIC protocol type to which the message belongs can be conveniently determined.
Under the condition that the message type is a short message, the protocol type judgment information comprises target connection ID information; the fourth determination submodule is configured to: acquiring a session table of an iQUIC protocol stack; searching target connection ID information from a session table; under the condition that the target connection ID information is found, determining that the QUIC protocol type of the QUIC message is an iQUIC protocol; and under the condition that the target connection ID information is not found, determining that the QUIC protocol type of the QUIC message is a gQUIC protocol. That is, after determining that the message type is a short message, the method is different from the above-mentioned long message processing method, specifically, the short message is encrypted and cannot be viewed in a data, so that the processing cannot be performed by the above-mentioned long message processing method. The QUIC connection process of the iQUIC protocol is further explained here: initiating a handshake message for the first time, similar to tcp handshake, and the difference lies in that the QUIC is not based on quadruplet but based on DCID as a connection identifier, after connection, session information is established and stored in the server, and the corresponding DCID is also stored in a session table in the iQUIC protocol stack. Under the condition that the message type of the QUIC message is determined to be a short message, in order to further judge whether the QUIC message belongs to a gQUIC protocol or an iQUIC protocol, a DCID is extracted from the QUIC message, the DCID is information which can be directly obtained, after the DCID of the QUIC message is taken, the DCID is searched from a session table of an iQUIC protocol stack, if the DCID is searched, the situation that the iQUIC message with the same connection exists before is shown, the protocol type of the new QUIC message is determined to be the iQUIC protocol, if the DCID is not searched, the protocol type of the QUIC message is determined to be the gQUIC protocol, because the corresponding DCID is stored in the session table only when the iQUIC protocol is connected for the first time, and the gQUIC protocol does not perform the processing. Therefore, the specific protocol type of the QUIC short message can be conveniently and accurately determined by the mode of searching the DCID in the session table of the iQUIC protocol stack.
Third, the embodiment of the present invention also provides a readable storage medium, on which computer instructions are stored, wherein the computer instructions, when executed by a processor, implement the above-mentioned QUIC message processing method.
Finally, the embodiment of the invention also provides gateway equipment, which comprises a memory and a processor, wherein the memory stores computer instructions, and the computer instructions are executed by the processor to realize the QUIC message processing method. The gateway device may be any gateway device that uses gQUIC protocol and iQUIC protocol, for example, in a preferred embodiment, the gateway device is an ingress gateway of the CDN.
