The following will describe in detail.

Example 1

Referring to fig. 1, fig. 1 is a flow chart illustrating a method for offloading congestion control according to an embodiment of the present invention. The method for offloading congestion control described in fig. 1 is applied to a network communication system, such as a local server or a cloud server for offloading congestion control management, which is not limited in the embodiments of the present invention. As shown in fig. 1, the method of offloading congestion control may include the operations of:

101. And acquiring congestion control information to be processed.

In the embodiment of the present invention, the first congestion control information includes at least 1 congestion control scheme information.

103. And carrying out optimization processing on the first unloading congestion control information to obtain target unloading congestion control scheme information.

It should be noted that, the congestion control information to be processed characterizes a congestion control protocol for network communication. Further, the congestion control protocol includes an active congestion control protocol and a passive congestion control protocol.

It should be noted that, the foregoing congestion control scheme information is coarse-grained, that is, the network communication scheme for offloading congestion control scheme information is of a framework nature. Further, the target offload congestion control scheme information is fine-grained, that is, the network communication scheme of the target offload congestion control scheme information has an explicit communication path, and the transmission rule of the data flow is clear.

It should be noted that, after obtaining the target unloading congestion control scheme information, the unloading congestion control of the data flow may include the following ways:

The data flow enters a buffer memory of a message management module from an access module interface;

after the data flow is arbitrated by the message management module, the data flow reaches the message distributor (built in the message management module);

the message distributor sends the memory resource with spare stored data and the spare read-write processing unit to the data transmission connection management module after confirming the memory resource with spare stored data and the spare read-write processing unit.

The data transmission management module stores the data transmission management module, establishes a memory resource queue in the data distribution unit and sends a connection request to the receiving end;

after receiving the request, the receiving end establishes a corresponding new memory resource queue in the receiving connection management module and returns connection reservation feedback information.

After receiving the connection reservation feedback information, the data stream is sent to a read-write processing unit distributed by a previous message distributor for processing.

The read-write processing unit takes data from the memory through the memory access module in a mode of directly accessing the memory according to the address information carried by the data stream and encapsulates the data into a data packet;

then the data packet is injected into a receiving end of the data subsystem through the access module;

after receiving the data packet, the receiving end writes the data packet into the memory in a mode of directly accessing the memory through the buffer write-back module, and informs the receiving connection management module of updating the byte number;

And the receiving connection management module judges that the data stream transmission completion signal is generated after all the data streams are received, and releases the memory resource queue according to the data stream transmission completion signal.

The receiving end comprises any one of a transmission connection management module, a receiving processing module and a receiving connection management module, and the embodiment of the invention is not limited.

Therefore, the method for unloading congestion control described by the embodiment of the invention is beneficial to reducing the CPU load, improving the congestion unloading efficiency and accuracy, further improving the network communication efficiency and reducing the system security risk.

when the second matching judgment result is negative, triggering and executing control protocol basic information in the control protocol information to be matched sequentially from left to right to be target control protocol basic information;

when the second matching judgment result is yes, triggering and executing to sequentially determine the control protocol information to be matched from the first list information of the control protocol matching relation table;

and determining a control basic template sequence corresponding to the target coordinate point information as a target control basic template sequence.

It should be noted that, the above-mentioned determination of the matching relationship between the basic information of the target control protocol and the congestion control information to be processed may be based on consistency of names of the protocols or on consistency of numbers of the protocols, which is not limited by the embodiment of the present invention.

It should be noted that, the intersection point of the second list information and the target row list information represents the intersection point of the target row and the second column in the same table. Further, the control protocol matching relation table includes a first column and a second column. Further, the first list information corresponding to the first column represents control protocol information, and the second list information represents a control basic template sequence corresponding to the control protocol information. Further, the control basic template sequence is composed of a plurality of sequence numbers, such as 12345,3456.

In yet another alternative embodiment, as shown in fig. 4, a congestion unloading system includes a control subsystem and a data subsystem; wherein,

the input end of the memory access module is respectively connected with the external environment, the output end of the data transmission management module and the output end of the buffer write-back module, and the output end of the memory access module is respectively connected with the external environment, the input end of the message management module and the input end of the data transmission management module; the input end of the data transmission management module is also respectively connected with the output end of the message management module, the output end of the transmission connection management module and the output end of the receiving processing module, and the output end of the data management module is also respectively connected with the input end of the sending arbitration module, the input end of the transmission connection management module and the input end of the receiving processing module; the output end of the sending arbitration module is respectively connected with the input end of the network interface module, the input end of the transmission connection management module and the input end of the receiving connection management module; the input end of the transmission connection management module is also connected with the output end of the receiving processing module, and the output end of the transmission connection management module is also respectively connected with the input end of the sending arbitration module, the input end of the buffer write-back module and the input end of the receiving processing module; the input end of the receiving processing module is also connected with the output end of the network interface module, and the output end of the receiving processing module is also respectively connected with the input end of the receiving connection management module and the input end of the buffer write-back module; the output end of the receiving connection management module is connected with the input end of the buffer write-back module;

the reservation feedback template is used for indicating the receiving connection management module to perform feedback processing on the resource application information received by the transmission connection management module so as to generate reservation feedback information; the reservation feedback information is used for indicating the memory access module to send a data stream according to the data specification in the reservation feedback information; the data specification includes a data stream transmission time interval, and/or a data volume size;

the sending scheduling template is used for indicating to adjust the data stream sending mode of the sending end; the transmitting end comprises a transmission connection management module and/or a transmission arbitration module and/or a transmission connection management module;

It should be noted that, the reservation application in the reservation application template is completed by the transmission connection management module, and the reservation feedback in the reservation feedback template is completed by the receiving connection management module.

The adjustment of the transmission scheme of the data stream at the transmitting end is to schedule between the transmission mode (speculative transmission mode and non-speculative transmission mode) and the transmission timing. Further, the scheduling space of the transmitting end is large, including scheduling when one data stream is just transmitted to select the next data stream to transmit, switching another data stream to have scheduling when one data stream is transmitting, and determining scheduling when transmitting in the form of a speculative transmission mode or a non-speculative transmission mode. Further, in the present application, the adjustment of the sending mode of the data stream at the sending end is implemented by decoupling between the message management module and the receiving processing module and switching the data stream in sending.

Furthermore, the foregoing implementation of adjusting the data stream transmission mode of the transmitting end by decoupling between the message management module and the receiving processing module is specifically: the condition that the data stream is fetched from the message management module is set to be that the memory resource for storing the data exists (without needing an idle processing unit), and the transmission connection management module is set to establish the memory resource for storing the data for all the data streams in local time, so that effective dispatching can be performed, and the transmission connection management module maintains a memory resource queue for storing the data and a read-write processing unit state queue in the data transmission management module so as to make more efficient decisions. In addition, the transmission connection management module needs to add corresponding information according to a control method in specific congestion control information to be processed, modify information carried by a connection request into a reservation request and maintain a corresponding state machine. Thus, all data streams are converged into the transmission connection management module after entering the data subsystem, and the transmission connection management module can schedule all data streams according to the state machine, select one of them for transmission (or speculatively transmit) or switch the data streams being transmitted.

Further, the switching of the data stream during transmission includes suspending and restarting the data stream, adding a buffer area in a downstream module of the receiving processing module, and implementing a speculative transmission function by using a semi-connection mode.

Specifically, the suspension and restart of the data flow may implement switching of the sending data flow in congestion control, for example, a high priority flow preempting a low priority or a trusted flow preempting no credit, etc. Although the reservation application is pipelined, the delay of the memory access module from the data stream entering the read-write processing unit to the first data packet is not negligible, which means that the overhead of the network card for switching the data stream for transmission is the delay of the memory access module, namely, the time-switched space is used.

Specifically, adding a buffer area in a downstream module of the read-write processing unit (data transmission management module) includes, when the read-write processing unit assembles a data packet and sends the data packet to the sending arbitration module, the sending arbitration module first stores the data packet in a buffer area. The scheduler performs scheduling according to a control method in specific congestion control information to be processed, such as the shortest remaining optimal or end-to-end credit scheduling. When the data packets of a plurality of streams are in the same buffer zone, no additional overhead is generated when the transmission streams are switched, which is a space-time switching method. Although adding a buffer to the data subsystem temporarily stores the data packets, the buffer is not the first location where the network card finds the stream to arrive. The network card first discovers the data flow in the message management module and then passes through a plurality of modules. This means that the several steps of discovering the data flow, issuing the reservation request and sending the schedule are not at the same time and at the same location in the data subsystem, where there is the possibility of finer granularity multi-level scheduling.

Specifically, the use of the semi-connection mode to realize the speculative transmission function includes that under the semi-connection protocol in congestion control information to be processed, a transmitting end directly transmits a data packet without connection establishment, no connection request is generated, and the transmitting end transmits a write completion event after the transmission is completed, wherein the event carries the length information of a data stream; the receiving connection management module of the receiving terminal network card inserts the related information of the data flow into the memory resource queue of the receiving terminal for storing data when the data packet or the event from the data flow is received for the first time, releases and returns the reservation feedback information to the transmitting terminal when the received data quantity is equal to the length carried by the writing completion event. The semi-connected mode of the data subsystem is utilized to support the speculative transmission process and is used in combination with the fully connected mode. While introducing a semi-connected mode increases the complexity of the state machine to which the transport connection management module corresponds, the accuracy and usability of such an architecture is higher.

It should be noted that, the adjustment of the reservation feedback information in the receiving and scheduling template further includes adjustment of a dynamic priority flow table, that is, a priority is set according to the length of the data flow, and whether to return a message to the sending end is determined according to the remaining length.

The adjustment of the data stream transmission rate is achieved by adjusting the number of transmission packets in a period. Furthermore, for the rate limiting function implemented in the network interface module, a sliding transmission window is provided in the network interface module, the sliding speed of the window is fixed, the size of each window can be obtained according to the limited rate and the sliding speed of the window, and the network interface module controls the data stream transmission rate by controlling the size of the window.

In yet another alternative embodiment, determining the first offload congestion control information based on the congestion offload system and the target control base template sequence includes:

determining target template information from a control subsystem in the congestion unloading system based on control base template sequence number information in a target control base template sequence;

sequentially arranging target templates in the target template information from top to bottom based on the arrangement sequence of the control basic template sequence number in the control basic template sequence number information to obtain template list information;

For any target template in the template list information, filling an execution module corresponding to the target template into a right side list of the target template based on the execution corresponding relation between the target template and the data subsystem to obtain target template module corresponding information corresponding to the target template; the number of the target execution modules in the corresponding information of the target template modules is between 1 and 3;

carrying out scheme construction on the corresponding information of all the target template modules to obtain first unloading congestion control information; each target template in the unloading congestion control scheme information in the first unloading congestion control information corresponds to a target execution module; the number of the unloading congestion control scheme information and the number of the target execution modules in the target template module corresponding information are in a combination relation.

It should be noted that each template in the control subsystem corresponds to a unique serial number. For example, the serial number of the reservation application template is No. 1, the reservation feedback template is No. 2, the speculative transmission template is No. 3, and the receiving and dispatching template is No. 4, if the serial number of the control basic template is 1234 in sequence, the reservation application template, the reservation feedback template, the speculative transmission template and the receiving and dispatching template are determined to be target templates, and the reservation application template, the reservation feedback template, the speculative transmission template and the receiving and dispatching template are sequentially arranged in a template list from top to bottom according to the arrangement sequence of 1234.

It should be noted that, the scheme construction of the corresponding information of all the target template modules is to sequentially select one target template module from the target templates, and then sequentially arrange all the selected target template modules to form an unloading congestion control scheme information. Further, each template in the control subsystem corresponds to at least 1 execution module, and after the target template is determined, the corresponding execution modules are sequentially filled into a right side list of the target template from left to right according to the data transmission sequence of the data subsystem, so that the corresponding information of the target template module corresponding to the target template is obtained.

It should be noted that, after the combination relation characterizes the target execution modules corresponding to each target template, a corresponding amount of unloading congestion control scheme information can be obtained. For example, when the number of target execution modules corresponding to the first target template is 3, the number of target execution modules corresponding to the second target template is 2, and the number of target execution modules corresponding to the third target template is 1, the amount of the offload congestion control scheme information is

In an optional embodiment, the receiving connection management module performs adjustment processing on the subscription feedback information, and includes:

the receiving connection management module identifies a data stream sending time interval in the reserved feedback information to obtain a target time interval;

the receiving connection management module determines the transmission time of the data stream based on the length of the data stream;

and when the time judgment result is negative, ending the flow.

It should be noted that, the data stream transmission time interval characterizes the time interval of the data stream injected into the network from the memory access module.

It should be noted that, the transmission time of the resource application information characterizes the transfer time of the resource application information from the access module to the transmission connection management module in the network.

In this optional embodiment, as an optional manner, the determining the data stream transmission time based on the data stream length includes:

acquiring the minimum transmission data stream length and the corresponding data stream time value;

dividing the data stream length by the minimum transmission data stream length to obtain a length dividing value;

and multiplying the target length divided value by the data stream time value to obtain the data stream transmission time.

and carrying out scheme information perfect processing on the congestion control scheme information to be optimized and unloaded based on the congestion control information to be processed, so as to obtain the target congestion control scheme information to be unloaded.

It should be noted that, the determining the to-be-optimized unloading congestion control scheme information randomly determines one unloading congestion control scheme information from the first unloading congestion control information as the to-be-optimized unloading congestion control scheme information.

It should be noted that, the above scheme information improvement processing of the congestion control scheme information to be optimized includes data updating of the information such as the data transmission path, the total length of the data stream, the credit packet corresponding to the data, the data storage address, etc. in the congestion control information to be optimized, which may be automatically completed by the system or fed back to the user, and the information is generated after the user fills in one by one and feeds back to the system to decode the data.
