Problems solved by technology

[0007] The above-mentioned retransmission method provided by the prior art usually adopts a fixed response time threshold and a fixed number of retransmissions, which will lead to redundant request messages when the communication delay between the server and the client is constantly changing. In the case of retransmission, retransmission of too late request message and premature abandonment, etc., the efficiency of message retransmission is low

Embodiment Construction

[0025] A method and device for sending a message provided by an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] The message sending method provided by the embodiment of the present invention improves the existing message resending mechanism. The message sending method that the embodiment of the present invention provides, not only can be applicable to RADIUS server and RADIUS client to solve the problem of low retransmission efficiency of RADIUS protocol message between RADIUS server and RADIUS client in the prior art, A skilled person can easily imagine that the message retransmission method provided by the embodiment of the present invention can also be applied to the retransmission of messages using other non-connection-oriented protocols that lack reliability, so as to improve the efficiency of message retransmission.

Abstract

The invention discloses a method and device for transmitting messages. The method comprises the following steps: executing the transmit operation of messages according to the preset number of transmissions of a single message and the preset response time threshold of each transmission; counting the actual response time of each transmitted message in the current period; calculating the average value of the actual response times of all the transmitted messages in the current period, adjusting the number of transmissions of each message and the response time threshold of each transmission according to the calculated average value; and executing the next period of transmit operation of messages according to the adjusted number of transmissions and the adjusted response time threshold of each transmission. By using the method and device of the invention, the dynamic adjustment of the number of transmissions of messages and the response time threshold of each transmission can be realized according to the actual network communication state, thus increasing the retransmission efficiency of messages.

Description

technical field [0001] The invention relates to the field of network data communication, in particular to a message sending method and device. Background technique [0002] In many existing network protocols such as the Remote Authentication Dial In User Service (RADIUS) protocol, the RADIUS protocol for interaction between a client (often called a RADIUS client) and a server (often called a RADIUS server) Packets are often transmitted using a User Datagram Protocol (UDP). [0003] Because UDP lacks reliability and is a non-connection-oriented protocol, it is easy to cause protocol packets transmitted using UDP, such as RADIUS protocol data packets, to be lost during network transmission. The RADIUS client and RADIUS server often pass through several second and third layers. The stability of the network connection cannot be guaranteed. The communication delay between the client and the server may change with the change of the network environment and the processing capabili...
