Problems solved by technology

If the other party cannot receive this message for some reason, the party receiving the last message will not be able to complete the negotiation process, and the negotiation will fail after reaching the maximum number of retransmissions
[0010] According to the above analysis, there are some problems in the existing retransmission mechanism, so that the negotiation parties cannot negotiate successfully in some situations where they could continue to negotiate.

Embodiment Construction

[0040] like Figure 4 As shown, the device for determining the retransmission strategy in negotiation in the present invention includes the following devices:

[0041] ●The input device is used to receive the messages received by the local end.

[0042] ●The retransmission counting device is used to store the number of times a message is sent.

[0043] ●The timing decision device is used for deciding to execute a retransmission task after a specified time interval.

[0044] ●The message analysis device is used to analyze whether the message received by the local end meets the condition of retransmission. The message analysis device is the most important device in the device, and its method of judging whether the message meets the retransmission condition is in line with the expanded retransmission scenario based on the new principle of retransmission.

[0045] ● The output device is used to output the judgment result of whether retransmission is required.

[0046]Both the ...

Abstract

The invention relates to a device and relative method for confirming the consulted retransmit strategy, wherein said device comprises: an input device, a retransmit account device, a timing decider, a report analyzer and an output device; can received the report; the retransmit account device is used to store the send times of one report; the timing decider is used to execute one retransmit service in an appointed time space; the report analyzer is used to analyze if the received report meets the retransmit condition; the output device outputs the judge result of retransmission; and the timing decider and the report analyzer are matched with the retransmit account device to decide the judged result. The invention can add the retransmissions without affecting the safety, to improve the consult success.

Description

technical field [0001] The present invention relates to the field of network communication, specifically, the present invention is a method and equipment for determining a retransmission policy in negotiation. Background technique [0002] With the widespread application of the IP protocol, the security of the IP protocol network has gradually become a concern of people. The IP protocol itself is an open protocol and does not contain security features. Plaintext IP packets may be tampered with, eavesdropped, or forged during transmission, and their security is seriously threatened. [0003] IPsec (IP Secunty) is a security mechanism on the IP layer, which provides protections such as confidentiality, integrity, and anti-replay for IP data packets. Security Association SA (Security Association) is a set of policies used by IPsec to protect data packets, including confidentiality and integrity algorithms, keys, etc. used. [0004] IPsec SAs can be manually configured or est...
