Abstract

本发明涉及通信技术领域，尤其涉及一种光突发数据包传输方法及装置，用于解决OBS网络中基于多信道传输光突发数据包导致丢包率较高的技术问题；本发明实施例中，源边缘节点可向目的边缘节点发送信息查询控制包，每个接收到该信息查询控制包的核心交换节点都要对其中携带的使用信息进行处理，从而最后到达目的边缘节点时，信息查询控制包中携带的就是整条链路的使用信息，目的边缘节点再把该使用信息发送回源边缘节点，源边缘节点可根据该信息确定用于传输光突发数据包的信道。这样，从传输光突发数据包之前就确定好整个传输路径中所能够使用的信道的情况，尽量避免光突发数据包在传输到中途时因信道不够用而被丢弃，减小OBS网络中的丢包率。
