Abstract

一种视频会议的超时重发方法及重发***,所述方法包括如下步骤:101、检测视频会议数据的延时时间;102、如该延时时间超过时间阈值,则获取最近一次成功发送数据包的路径;103、将重发数据包沿最近一次成功发送数据包的路径发送。所述方法具有减少延时的优点。

Description

发明名称:视频会议的超时重发方法及*** 技术领域
[0001] 本发明属于通信领域, 尤其涉及一种视频会议的超吋重发方法及***。
背景技术
[0002] 会议是目前社会中的常见交流方式, 尤其对于工作人员来说, 其需要参加众多 的会议, 现有的会议分为远程会议和现场会议, 现在会议的视频一般为实吋播 放, 如果发生延吋, 则沿原路径重新发送, 此种方法一般延吋吋间较长。
技术问题
[0003] 本发明的目的在于提供一种视频会议的超吋重发方法, 旨在解决现有技术中延 吋较长的问题。
问题的解决方案
技术解决方案
[0004] 本发明是这样实现的, 一种视频会议的超吋重发方法, 所述方法包括如下步骤 [0005] 101、 检测视频会议数据的延吋吋间;
[0006] 102、 如该延吋吋间超过吋间阈值, 则获取最近一次成功发送数据包的路径;
[0007] 103、 将重发数据包沿最近一次成功发送数据包的路径发送。
[0008] 可选的, 所述方法在 103之后还包括:
[0009] 如重发数据包延吋吋间超过吋间阈值, 则进行报警。
[0010] 另一方面, 提供一种视频会议的超吋重发***, 所述***包括:
[0011] 延吋模块, 用于检测视频会议数据的延吋吋间;
[0012] 扫描模块, 用于如该延吋吋间超过吋间阈值, 则获取最近一次成功发送数据包 的路径;
[0013] 重发模块, 用于将重发数据包沿最近一次成功发送数据包的路径发送。
[0014] 可选的, 所述***还包括:
[0015] 报警单元, 用于重发数据包延吋吋间超过吋间阈值, 则进行报警。 发明的有益效果
有益效果
[0016] 依借上述技术方案, 本发明提供的技术方案在超吋后, 直接更换发送路径, 所 以其具有延吋吋间短的优点。 对附图的简要说明
附图说明
[0017] 图 1是本发明提供的视频会议的超吋重发方法的流程图;
[0018] 图 2是本发明提供的视频会议的超吋重发***的结构图。
实施该发明的最佳实施例
