Example two

Fig. 2 is a flowchart of another processing method of a communication request according to the second embodiment of the present invention, where the technical solution of the embodiment of the present invention is further optimized based on the foregoing alternative technical solutions.

Further, the allocation weight based on each candidate link is further refined into the allocation of the target link for the communication request from each candidate link according to the bandwidth required by the communication request and the aggregation type to which the communication request belongs, and whether the residual bandwidth of a single candidate link meets the bandwidth required by the communication request is determined according to the current state data of each candidate link; if not, taking the allocation weight of each candidate link as the allocation probability of the corresponding candidate link, and selecting at least two target links from each candidate link for the communication request by adopting the allocation probability; determining the specific weight of data on the target links by adopting the distribution weights of at least two target links, fragmenting the data to be transmitted of the communication request according to the data ratio to obtain at least two data fragments, and distributing the at least two data fragments to the at least two target links so as to improve the network utilization rate, the safety, the reliability and the stability. It should be noted that, in the present embodiment, parts not described in the present embodiment may refer to the related expressions of other embodiments, which are not described herein.

As shown in fig. 2, another method for processing a communication request according to an embodiment of the present invention specifically includes the following steps:

S210, determining the bandwidth required by the communication request according to the application program, the IP address, the interface and the transmission protocol to which the communication request belongs.

S220, determining the aggregation type of the communication request according to the application program, the transmission protocol and the data volume of the communication request.

Specifically, in response to the received communication request, the bandwidth to which the communication request belongs may be determined according to the application program, the IP address, the interface, and the transmission protocol to which the communication request belongs; the type of aggregation to which the communication request belongs may be determined based on the application, transmission protocol, and amount of data to which the communication request belongs.

The aggregation type to which the communication request belongs can be used for representing whether the communication request is suitable for aggregation, and the aggregation types to which different communication requests belong can be manually pre-designated or can be obtained dynamically by further analyzing the communication request.

And determining the bandwidth required by the communication request and the aggregation type of the communication request according to the data information of the communication request so as to facilitate the follow-up work according to the acquired information of the communication request.

S230, determining whether the residual bandwidth of each candidate link meets the bandwidth required by the communication request according to the current state data of each candidate link aiming at the communication request with the aggregation type suitable for aggregation.

And S240, if not, taking the allocation weight of each candidate link as the allocation probability of the corresponding candidate link, and selecting at least two target links from the candidate links for the communication request by adopting the allocation probability.

Specifically, in the case that the aggregation type to which the communication request belongs is suitable for aggregation, whether the residual bandwidth of the single candidate link meets the existence of the bandwidth required by the communication request can be judged according to the current state data of each candidate link. If not, that is, if there is no bandwidth that the remaining bandwidth of the single candidate link satisfies the bandwidth required by the communication request, at least one candidate link needs to be provided for the bandwidth required by the communication request, then the allocation weight of each candidate link can be used as the allocation probability of the corresponding candidate link, and at least two target links are selected for the communication request from each candidate link according to the allocation probability obtained at the moment.

When the target link is selected according to the allocation probability, the allocation weight of each candidate link may be used as the allocation probability of the corresponding candidate link, or the allocation probability may be obtained by performing weighted calculation on the allocation weight. For example, if the allocation weights of the candidate links are respectively 10%, 20%, 30% and 50%, where the allocation weights of the candidate links are regarded as the allocation probabilities of the corresponding candidate links, the corresponding allocation probabilities may be determined to be 9.1%, 18.2%, 27.3% and 45.4%, so as to equalize the data on the candidate links, and then at least two target links are selected for the communication request from the candidate links based on the allocation probabilities.

According to the method, for the communication request suitable for aggregation, under the condition that the current state data of each candidate link does not have the bandwidth required by the single candidate link to meet the bandwidth required by the communication request, according to the provided determination method of the allocation weights of the candidate links, the obtained allocation weights are used as the allocation probability of the corresponding candidate links, and at least two target links are selected for the communication request, so that the communication request is conveniently selected to be suitable for the target links, and efficient transmission of the data is realized.

In addition, in an implementation manner of an alternative embodiment, based on the allocation weight of each candidate link, a target link is allocated to the communication request from each candidate link according to the bandwidth required by the communication request and the aggregation type to which the communication request belongs, and the method further includes: if the residual bandwidth of the single candidate link meets the bandwidth required by the communication request, taking the allocation weight of each candidate link as the allocation probability of the corresponding candidate link, and selecting a unique target link from each candidate link by adopting the allocation probability; the data to be transmitted of the communication request is assigned to the selected target link.

Specifically, if there is a bandwidth that the remaining bandwidth of a single candidate link satisfies the bandwidth required by the communication request, that is, for a communication request with a single link aggregation type, the allocation weight of each candidate link may be used as the allocation probability of the corresponding candidate link, and the obtained allocation probability is used to select a unique target link from each candidate link for the communication request, and then allocate the data to be transmitted of the communication request to the selected target link. In particular, for the communication request with the single link aggregation type, the selection manner of selecting the unique target link for any communication request based on each candidate link is not limited.

For a communication request with a single link aggregate type, the allocation weight of each candidate link can be used as the allocation probability of the corresponding candidate link, and the allocation probability is adopted to select a unique target link for the communication request from the candidate links; and distributing the data to be transmitted of the communication request to the selected target link so as to facilitate distributing a proper target link for the communication request of the single link to carry out data transmission work of the data to be transmitted.

S250, determining the proportion of data on the target links by adopting the distribution weights of at least two target links, fragmenting the data to be transmitted of the communication request according to the data ratio to obtain at least two data fragments, and distributing the at least two data fragments to the at least two target links.

Specifically, based on the allocation weights of at least two target links, the specific gravity of the data on the target links can be determined, then the data to be transmitted of the communication request is fragmented according to the data ratio, at least two data fragments can be obtained, and the at least two data fragments are allocated to the at least two target links.

For example, in S240, the method may further include determining the specific gravity of the data on the corresponding target link based on the obtained allocation weights of the at least two target links, and then slicing the data to be transmitted of the communication request according to the data ratio to obtain at least two data slices, and allocating the at least two data slices to the at least two target links, so as to facilitate development of the subsequent work.

And S260, executing the communication request by adopting the distributed target link.

Specifically, based on the assigned target link, the communication request may be performed based thereon. The embodiment of the invention does not limit the execution mode of the communication request based on the allocated target link.

According to the embodiment of the invention, the bandwidth required by the communication request is determined according to the application program, the IP address, the interface and the transmission protocol to which the communication request belongs; determining the aggregation type of the communication request according to the application program, the transmission protocol and the data volume of the communication request; for a communication request with the aggregation type suitable for aggregation, determining whether the residual bandwidth of a single candidate link meets the bandwidth required by the communication request according to the current state data of each candidate link; if not, taking the allocation weight of each candidate link as the allocation probability of the corresponding candidate link, and selecting at least two target links from each candidate link for the communication request by adopting the allocation probability; determining the specific weight of data on the target links by adopting the allocation weights of at least two target links, fragmenting the data to be transmitted of the communication request according to the data ratio to obtain at least two data fragments, and allocating the at least two data fragments to the at least two target links; if the residual bandwidth of the single candidate link meets the bandwidth required by the communication request, taking the allocation weight of each candidate link as the allocation probability of the corresponding candidate link, and selecting a unique target link from each candidate link by adopting the allocation probability; distributing the data to be transmitted of the communication request to a selected target link; executing the communication request by adopting the distributed target link; the technical scheme provided by the embodiment of the invention is convenient for improving the network utilization rate, safety, reliability and stability by dynamically determining the distribution weight of each candidate link, selecting the target link based on the distribution weight and executing the communication request.

Example III

The processing method of the communication request set forth in the present invention is better understood and known by those skilled in the relevant arts, and the overall processing logic of the communication request is further illustrated.

In an implementation manner of a specific embodiment, as shown in a schematic diagram of a module design architecture provided in an embodiment of the present invention in fig. 3A, the module design architecture includes a multilink aggregation terminal and a multilink aggregation server. In particular, data transmission is performed between the multilink aggregation terminal and the multilink aggregation server through a plurality of communication links. The multi-link aggregation terminal comprises an intelligent data distribution/classification module, a link state detection module, a multi-link aggregation module and an encryption module; the multilink aggregation server comprises an encryption module and a multilink aggregation module.

After a communication request of a user enters a system, the communication request is distinguished through an intelligent data distribution/classification module, the module can classify the current communication connection through information such as an application program, a target IP (Internet protocol) and an interface of the communication data, a transmission protocol, a response time length and the like according to the configuration items of the requested network data, history data and actual scene requirements, and the module judges the distribution processing of different security level information: direct forwarding, forwarding after encryption processing by using a specified mode, forwarding by using multi-link aggregation, and forwarding after multi-link aggregation after encryption processing by using a specified mode. Network data including, but not limited to, applications, transmission protocols, response time, communication bandwidth; the history data includes, but is not limited to, local history records, and can be obtained by modifying network data based on an iterative learning algorithm of machine learning.

The encryption module is responsible for key management and encryption and decryption calculation of data, and the multilink aggregation module is used for calling and participating in the encryption and decryption calculation of communication data according to configuration requirements, so that the encryption module can be used for representing the security level in the data transmission process. The multi-link aggregation module can judge different processing modes of the data according to the intelligent data distribution/classification module, calls the encryption module to encrypt and decrypt the data corresponding to the requirement, and distributes one or more links for each communication according to the states of a plurality of links which can be used. In the communication process, the module does not need to aggregate the transmitted data, and selects a proper link for transmission and reception; the data to be transmitted in an aggregation way is segmented or combined, a plurality of links are selected to forward and receive the data, and data transmission is carried out between a transmission control protocol (Transmission Control Protocol, TCP) protocol and a multilink aggregation server. Among other things, TCP is a connection-oriented, reliable, byte stream based transport layer communication protocol intended to accommodate a layered protocol hierarchy supporting multiple network applications. Reliable communication services are provided by means of TCP between pairs of processes in host computers connected to different but interconnected computer communication networks. TCP assumes that it can obtain simple, possibly unreliable datagram services from lower level protocols. In principle, TCP should be able to operate over a variety of communication systems from hardwired to packet-switched or circuit-switched networks. The link state monitoring module can track the link state information such as the communication rate, the packet loss rate, the network fluctuation and the like in each link in real time, provides a basis for dynamically adjusting the distribution proportion of each link to be sent to the intelligent data distribution/classification module, and improves the utilization rate of each communication link.

Particularly, the multilink aggregation server side synchronizes encryption configuration of the multilink aggregation terminal, calls an encryption module to encrypt and decrypt data corresponding to the requirement, segments or combines the data, forwards and receives the data through a plurality of links, and uses a TCP protocol to transmit the data with the multilink aggregation terminal.

That is, the intelligent data distribution/classification module adopts a mode of combining a machine learning algorithm and configuration to realize the allocation of security level, required bandwidth reservation, communication priority and the like to the communication request entering the system, and the machine learning algorithm used by the module can train a large amount of communication data in a network and automatically learn and update according to the historical operation data of the equipment; the method can predict the data such as information security level, occupied network bandwidth, requirement on network delay, active duration and the like used by the newly-appearing communication request in the network; the configuration item may configure security level and communication priority of communication requests focused on IP, application, port, such as: real-time traffic may be of higher priority than non-real-time traffic; for large communication data volume, such as large file transmission, video communication, video conference and the like, whether the request is suitable or not and whether multiplexing is needed or not is judged.

The multilink aggregation module comprises a multilink dynamic allocation algorithm which can dynamically adjust the data transmission rate of each link according to the real-time bandwidth condition of each link, ensure that the data transmission rate of each link has better compatibility, avoid the problems of congestion, data packet loss and the like, and ensure the data transmission efficiency of the whole network; the algorithm can dynamically allocate one or more proper links for communication according to the priority of different communication requests, the expected occupied network bandwidth, the requirement on network delay, the expected active time length and other attributes, and if a certain link fails or the bandwidth is insufficient, the algorithm can dynamically adjust the link used by the communication connection so as to ensure the continuity and high availability of communication, namely, the link is updated in real time. When links are allocated, an optimized allocation strategy is adopted, links which just meet the requirements of the links are allocated to one request, and the residual link bearing capacity is ensured to be balanced as much as possible, so that the subsequent communication request can be ensured to be allocated to the appropriate links.

When determining a link according to data information to which a communication request belongs, there are three cases, respectively illustrated as follows:

Case one: when all links are idle, a communication request enters the system, the intelligent data distribution/classification module judges whether the communication request is suitable or needs to be aggregated, the bandwidth needed by the communication request is normally used in the guarantee period, the network delay used by the communication request is not influenced, the security level of the communication request is not influenced, and then the multi-link aggregation module distributes links for the communication request according to the result given by the intelligent data distribution/classification module: if the request is a request that does not require aggregation, such as: a login request; the multilink aggregation module allocates a link to the communication request according to the current link state, namely the allocation weight of the candidate link, and then completes the subsequent communication process of the communication request through the link; if the communication needs to be aggregated, such as: large file transmission/downloading, video communication and the like, the multi-link aggregation module allocates a link to the communication request according to the current link state if a single link bandwidth can meet the bandwidth required by the communication request, allocates a plurality of links to the communication request if a single link cannot meet the bandwidth required by the request, ensures that the communication bandwidths of the links meet the requirement of the communication request, and then completes subsequent communication of the communication request through the allocated one or more links.

And a second case: when all links are busy, a communication request enters the system, the intelligent data distribution/classification module still needs to determine whether the communication request is suitable or needs to be aggregated, the bandwidth needed to be used by the communication request is normally used in the guarantee period of the communication request, the network delay used by the communication request is not affected, the security level of the communication request is not affected, and then the multi-link aggregation module distributes links for the communication request according to the result given by the intelligent data distribution/classification module: if the request is a request that does not require aggregation, such as: a login request; the multilink aggregation module selects a link with residual communication capacity from busy links according to the current link state to the communication request, and then completes the subsequent communication process of the communication request through the link; if the communication needs to be aggregated, such as: large file transmission/downloading, video communication and the like, a multi-link aggregation module allocates a link to a communication request according to the current link state if a single link residual communication bandwidth can meet the bandwidth required by the communication request, if no single link meets the bandwidth required by the request, a system analyzes the communication pressure of each link, allocates a plurality of links to the communication request, reasonably allocates communication shares on each link according to the communication condition and bearing capacity of each link, ensures that the communication bandwidths of the links meet the requirements of the communication request, and then completes subsequent communication of the communication request through one or more allocated links; if all the links have large communication pressure and the residual communication capacity does not meet the bandwidth required by the request, the system also allocates a plurality of links to the communication request according to the current communication condition and the link network state of each link, distributes the communication pressure of the communication request according to the state of each link, and then uses a slow sending and queuing strategy to finish more higher-level communication requests as much as possible, thereby ensuring the high availability of the system.

Case three: when all links are busy, if the network state of one communication link suddenly worsens, that is, when the sudden fault cannot work normally, the multi-link aggregation module updates the routing table and distributes weights according to other link states, picks the links with the residual communication capacity to the request in the communication link, completes the subsequent communication process through the newly distributed links, and distributes at least one proper communication link according to the attribute of the request. The allocation weights include, but are not limited to, current available bandwidth, response time, packet loss rate and other current communication states and stability. The stability is that the fluctuation range of the bandwidth, the fluctuation range of the response time length and the fluctuation range of the packet loss rate are evaluated through historical communication data, and then the stability is obtained.
