Problems solved by technology
These two methods can improve the reliability of communication, but the problem is also very obvious: greatly increasing the complexity of the system, especially increasing the complexity of the implementation of the receiving end is unacceptable in practical engineering applications, because many The network management system uses a ready-made access platform, and customers will definitely not adopt the method of modifying the system for the above-mentioned patents, so its practical effect is greatly reduced

Embodiment Construction
[0026] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0027] see figure 1 , the sender 1 and the receiver 2 transmit data through an unreliable transmission channel, and the two can be in a peer-to-peer relationship, or in a client layer / server relationship. The sender 1 is the initiator of the communication, responsible for organizing the data packets and sending the data to the unreliable transmission channel; the receiver 2 is the receiver of the data packets, and completes the reception and processing of the data packets sent by the sender. see figure 2 , the sender 1 includes an initialization module 101 , a data packet sending module 102 , a data packet generating module 103 and a data packet buffer queue 104 .
[0028] Take the transmission reliability control process of TRAP in the SNMP protocol as an example, please refer to figure...

The invention discloses a method to increase single-way communication reliability under the condition of an unreliable communication environment. The method mainly relates to a data transmission performed by a sender and a receiver of single-way communication through an unreliable transmission channel. The sender, being as a communication initiator, is responsible for organizing a data package and sending the data to the unreliable transmission channel; the receiver is the accepter of the data package, and accomplishes the receiving and the processing of the data package sent by the sender. Through adjusting the sending course, the invention can increase the reliability of the single-way communication to a great extent, in particular, under the circumstance of mass data, the invention evenly sends the data according to a certain time interval, thereby well adjusting the network flow quantity, alleviating the condition of the network blockage, and having a very obvious effect on reducing the package-lost rate; in addition, as the invention gives consideration to both the data package delayed-storage number and the size of the package sent out every time, the influence on the effectcan be controlled in an acceptable range, the communication reliability is increased under the circumstance of completely not adding any work to the receiver.
Description
technical field [0001] The invention belongs to the field of unreliable data communication transmission preprocessing, and in particular relates to a method for improving the reliability of one-way communication in an unreliable communication environment. Background technique [0002] Communication protocols can be divided into reliable transmission and unreliable transmission from the perspective of reliability. Some network management standards choose unreliable communication protocols as the underlying transmission support in order to take into account factors such as efficiency and implementation simplicity. For example, the unreliable UDP protocol is used in the SNMP protocol (Simple Network Management Protocol, Simple Network Management Protocol) (User Datagram Protocol, User Datagram Protocol). When choosing unreliable transport, there is a possibility of packet loss, especially when the network is busy. One-way transmission Due to the lack of interaction between th...
