Problems solved by technology

[0005] The object of the present invention is to provide a data block out-of-order testing method and device based on RFC6349, the method and device process out-of-order data blocks by caching and processing the data serial number and the initial expected data serial number to solve The problem of large buffer space is required, and when receiving out-of-sequence serial numbers, three confirmation serial numbers are sent directly and continuously, triggering fast retransmission at the sending end to solve the problem of low data transmission efficiency

Abstract

The invention provides an RFC6349-based data block out-of-order test method and apparatus. The method comprises the following steps: receiving an initial expected data sequence number and a data sequence number sent by a data block sending state machine; matching the data sequence number with the initial expected data sequence number; when the data sequence number is matched with the initial expected data sequence number, updating the initial expected data sequence number to serve as the initial expected data sequence number of the next time; and when the data sequence number is not matched with the initial expected data sequence number, caching the data sequence number and the initial expected data sequence number. By adoption of the method and apparatus provided by the invention, the data do not need to be cached, so that the cache space is saved.

Description

technical field [0001] The invention relates to the field of RFC6349 testing, in particular to a method and device for out-of-sequence testing of data blocks based on RFC6349. Background technique [0002] In the TCP transmission protocol, data is transmitted in blocks. Due to the inherent delay of the network itself, the choice of transmission paths, and the processing time of devices, etc., the TCP data blocks or data packets originally sent in order will be delayed when they arrive at the receiving end. It may become out of order, the first one may arrive later than the last one, and it may be discarded in the network. In this case, the data needs to be reorganized out of order and retransmitted. The existing out-of-order processing method generally caches out-of-order data blocks until the data block with the expected sequence number is received, and then submits these continuous data blocks to the upper application for processing. Therefore, the existing out-of-order pr...
