Description
Technical Field
The invention relates to a network data interaction method.
Background
Modern internets mostly employ store-and-forward packet switching technology, and a three-tier ISP architecture, in which computer networks can be divided into wide area networks, metropolitan area networks, local area networks, etc., according to the scope of the application.
With the rapid development of the aerospace field in China, the existing aerospace design institute and the subordinate professional processing system thereof are distributed in all regions of the country. Nowadays, the real-time collaborative data demand for the same model of equipment is increasing. Compared with the original multi-region centralized office system of designers, the establishment of a set of special high-speed wide area network cross-network-segment data interaction system can appropriately release the original limitations of regions, manpower, fields and the like, and greatly improve the processing efficiency of multi-region collaborative office.
The existing network data interaction method cannot effectively ensure the real-time processing in different places.
Disclosure of Invention
In view of the above problems, the present invention provides a high-speed network software processing system based on a dedicated wide area network, which is used to transmit and process information to be tested in real time or quickly. The system combines DES optimization algorithm and software data processing optimization, and is applied to a suitable ground integrated system in parallel to improve DES encryption and decryption processing rate.
How to rapidly interact data in a remote independent network based on a cross-network end, the purpose of the invention can be realized by the following technical scheme:
optimizing the environment of the special network equipment:
analyzing the characteristics of a large amount of special data interaction in the system, and designing a special high-speed wide area network cross-network segment network environment:
1) the method comprises the following steps of designing a special network environment of direct-transmission data by utilizing the uniqueness of physical MAC addresses in all hosts, connecting the hosts through a switch, storing and maintaining a host MAC address table, and storing and maintaining all host MAC address tables through the switch by the data so as to ensure the accuracy and the uniqueness of the direct-transmission data interaction path;
2) aiming at the problem of large number of system hosts in a cross-network-segment wide area network, the positioning efficiency is too low and the limitation is strong through MAC addressing in a unilateral way, and through the arrangement of IP addresses in regions and processing characteristics of all processing hosts, an ARP table of the corresponding relation between the IP addresses of the hosts and the MAC addresses is maintained regularly.
The method flexibly utilizes the characteristics of the MAC and the IP, ensures the uniqueness of the host, improves the addressing efficiency by maintaining the ARP table, and effectively reduces the data interaction time.
Optimizing the total network time delay:
the total network delay is composed of transmission delay, propagation delay, processing delay and queuing delay.
In order to reduce the total delay, the network architecture and the software transceiving mechanism need to be optimized one by one according to the environmental characteristics, so as to reduce each delay.
And (3) sending time delay:
the sending time delay is the time required by the host or the router to send the data frame, and in order to optimize the time delay, the length of the data frame is reasonably set, and the sending rate is increased.
Propagation delay:
the propagation delay is the time that the electromagnetic wave needs to take to propagate a certain distance in a channel, and the transmission rate of the electromagnetic wave is a fixed value.
The method achieves the purpose of reducing the propagation delay by reasonably designing the network link and reducing the propagation distance.
Processing time delay:
the processing delay is the time required for processing when a packet is received by a host or a router.
The method mainly aims at processing time delay, optimizes network layout and designs a reasonable processing software platform to reduce the processing time delay generated by interaction of all branch systems. The method comprises the following design steps of assigning a processor to process network data through software, fully utilizing all resources of a platform to achieve the purpose of accelerating:
1) the data storage and forwarding are carried out while the data packet is exchanged, and as the data only forwards the packet but not the message, a long message needs to be cut into a plurality of packets with reasonable lengths so as to optimize the processing delay of single packet data;
2) the software puts the packed data into a virtual queue to accelerate the processing efficiency of real-time data;
3) and a virtual real-time response mechanism is set, and the states of the pre-processed data packet, the CPU processing core number and the processed data packet are updated through a virtual runtime service mechanism, so that all resources in the computer can be reasonably utilized within the shortest time efficiency, and the orderliness of the processed data is ensured.
Through actual measurement, the data interaction of the optimized platform is increased to 2-3 times, and the phenomenon of network packet loss is almost avoided.
Queuing delay:
queuing delay is the time a packet waits in the input queue and output queue of a router, and its size generally depends on the current traffic volume of the network.
The method sets a network data interaction processing software system which is responsible for a queue queuing waiting mechanism and a data in-out queue sequence when specially processing each data interaction.
The whole network data interaction processing software system is divided into three parts: a data input queue mode, a data queue queuing mechanism and a data output queue mode.
1) When data packets to be interacted sent by different source ends enter the router, the network data interaction processing software system triggers the real-time response system, distributes respective independent configuration codes according to a pre-configured data interaction mapping table, and then enters a data stack of a response class to wait for subsequent data processing.
2) In each data stack buffer area, the processing software optimizes each data queue according to different configuration codes, prevents queue blockage caused by periodic voice and image data and ensures real-time transmission of each control command, wherein the software needs to call a real-time response system to be inserted into the corresponding queue position again according to the configuration code identification every time new data enters a queuing queue. In order to improve the queuing processing efficiency, the method adopts a layer-by-layer classification mode, optimizes a retrieval path through a multilayer classification retrieval mode, and reduces the queuing delay consumed by retrieval.
3) When different data are output from the queues through the router, the real-time response system dynamically refreshes the queues, ensures that the packets currently out of the queues are the data with the highest priority, indexes the data configuration identification, and directly sends the data to the designated destination address.
Due to the adoption of the technical scheme, the high-speed processing system for network data interaction has the following advantages compared with the traditional network system:
real-time performance: compared with the traditional network system, the time consumption of the invention is greatly reduced. Compared with the traditional direct connection type network mode, after the network processing software system is used, the network receiving and sending rate can be improved by about 20%, periodic data and real-time control data can be distinguished, and real-time sending of control instructions is guaranteed.
Flexibility: the invention is mainly based on a network rapid processing software system, a core system is set to distribute and operate one by depending on all levels of configuration forms which are manually preloaded, all preloaded forms can be reloaded according to the change of a real-time environment, any software configuration item is not required to be added, and the design is flexible and simple.
Portability: the invention is mainly based on a network rapid processing software system, and the core operation configuration form can be reloaded after being modified in a background. All physical interaction layers of network transceiving of the whole operating system adopt a universal network protocol, and a user can change a replacement configuration form according to new requirements to finish system transplantation.
The cost is saved, compared with tens of thousands of expenditure investment and time cost of hardware debugging, the whole network rapid processing software system only needs to consume the initial software research and development cost. On the premise of not calculating hardware design loss, the whole system can only be used for the only calculation network condition state after being developed, and if the state and the like are changed, extra research and development cost and time are required to be invested for hardware modification and debugging. The network rapid processing software system designed by the invention is based on a software mode and has strong universality and easy operability. In addition, the modular design enables many changes to be made only by simple configuration of a user according to the description, so that the adaptation requirement of the whole new environment can be met, and the cost of expenses and time is greatly saved.
