The method comprises the steps that a high-speed data processing platform based on a domestic operating system kernel mode manages a data link according to tasks and can support local and remote control of the tasks; the task management software and the data receiving and forwarding software exchange data in a shared memory mode, so that the task statistical information is reported;
In order to avoid that a switch automatically releases a multicast link due to the fact that data are not sent for a long time when UDP multicast communication is carried out, task management software sends link monitoring information according to a 1 second/packet cycle when no data are sent; meanwhile, in order to facilitate users to know the transmission state of the task in time, the task management software supports the transmission function of the overall multitask report, and automatically sends forward/return transmission state report information to the task management software after receiving a forward/return transmission state report calling command;

(5) System performance index
a) the actual test return high-speed data distribution performance reaches 2 × 725 Mbps;
b) After the storage function is added, the processing speed of the whole machine reaches 2 × 680Mbps +20 Mbps. A
The realization process of the high-speed network IO kernel multi-protocol support comprises the following steps:
the high-speed data processing platform based on the kernel state of the domestic operating system can support high-speed backward data services and medium-low speed forward backward data services, three communication protocols of TCP, UDP unicast and UDP multicast are simultaneously supported among the ground station data transmission terminal, the data receiving and forwarding software of the data processing platform and the user center, and the specific mode is set through a configuration file so as to meet the requirements of later data forwarding services. When the task management software starts a task, reading a task configuration file and informing the data receiving and forwarding software to start a data forwarding task, wherein a high-speed data receiving module and a data forwarding module of the data receiving and forwarding software respectively create a corresponding TCP/UDP unicast/UDP multicast communication socket according to configuration information, and data receiving and sending processing is completed.
The TCP protocol guarantees reliable transmission of data mainly by the following mechanisms:
in terms of data correctness and legality, TCP uses a checksum function to check whether data has errors, and the checksum is calculated during sending and receiving;
In the aspect of ensuring reliability, an overtime retransmission and piggybacking confirmation mechanism is adopted;
In flow control, a sliding window protocol is used, which specifies that for unacknowledged packets within a window, retransmissions are required.
The UDP protocol is divided into a unicast mode and a multicast mode, wherein the unicast mode refers to that a data source and a data target are both unicast addresses (a host IP), and point-to-point data transmission is realized similar to a TCP protocol; multicast is a host IP as a data source, where a group of hosts receives data at a logical group address, and point-to-multipoint network connection is implemented between a sender and a receiver, and is applied more in a scenario where the master and the slave receive data simultaneously.
According to the requirement of service development, when the PDXP data frame is forwarded by a subsequent task through a TCP protocol, the bound transcoding processing of a data packet is required. The index is not realized in the high-speed distribution of 2 × 150Mbit/s at present, and the main reason is that the data packet sticking phenomenon exists when the TCP protocol is adopted for data transmission. In order to solve or avoid the problems of TCP package sticking and unpacking, the escape processing module of the data receiving and forwarding software adopts a 'data forwarding delimiting escape' technology.
the realization process of improving the transcoding performance of data forwarding delimitation is as follows:
When the data source of the invention transmits data, 1 byte unsigned number is respectively added at the head and the tail of a data frame, which are called as a data domain Head (HD) and a data domain Tail (TA), the data domain head and the data domain tail are both filled with a 16-system number 7EH, all data between the data domain head and the data domain tail are required to be transformed during transmission, all effective data with the value of 7EH are replaced by 7D5EH, and all effective data with the value of 7DH are replaced by 7D5DH, which is the encoding of the data. When the data transmission device receives the data, the data transmission device carries out reduction processing on the data, firstly searches for a data field head and a data field tail delimiter of '7 EH', and then converts all data between the data field head and the data field tail, namely all '7D 5 EH' are replaced by '7 EH', all '7D 5 DH' are replaced by '7 DH', and the decoding is carried out on the data. After the transcoding processing is adopted, even if the phenomena of packet sticking and unpacking occur in a TCP transmission layer, a complete data can be analyzed out by accurately utilizing the characteristic marks of the frame head and the frame tail in an application layer, so that the problem of data disorder during multi-user data forwarding is solved.
because the consumption of the CPU in the process of the escape processing is very large, the current program implementation mode is difficult to reach the data transmission index after the escape processing is finished. Through analysis, the main reason for improving the escape performance is that the processing links are all executed in series, and the platform is supposed to realize 2 × 640Mbit/s escape processing in a multi-stage pipeline parallel processing mode.
After a high-speed data processing platform based on a domestic operating system kernel state receives a return network data packet sent by a ground station data transmission terminal, all data needs to be stored in a specified data storage directory so as to facilitate subsequent analysis and processing; in order to ensure that other servers can implement business operations such as post-data analysis, archiving, file class retransmission and pushing and the like based on received return data, a shared file system is adopted by a data storage module of data receiving and forwarding software (provided with a Linux operating system), and all data is stored through a file storage server (provided with a Solaris operating system).
the Linux & Solaris cross-platform data file sharing is realized by the following steps:
the high-speed data processing platform adopts a domestic kylin Linux operating system to store data, adopts an FTP (file transfer protocol) to realize remote file transmission with a Sun file server, finishes the falling storage of the data by the Sun file server, and provides file access service for other servers through a QFS (quad Flat server) file system.
the invention is not described in detail and is within the knowledge of a person skilled in the art.
