【摘要】 本文通过分析OTN网络的客户信号映射过程,采用了一种基于GFP通道标签的电交叉方法,用于将GFP码流映射进ODUflex单元。并且,在此基础上,设计了一种基于贪婪算法的交叉调度算法用于GFP码流的交叉复用,该算法兼顾了OTN网络传输处理的有效性和灵活性。在最极端的情况下,可以提高OTN网络50%的带宽利用率。更多还原

【Abstract】 This paper analyzes the client signal mapping process of the OTN network and proposes a method of electrical cross and multiplex based on the GFP channel ID.This method is used to mapping GFP client signals into ODUflex.Furthermore,we design an algorithm according to the greedy algorithm used to the cross and multiplex of GFP client signals.Taking into account the flexibility and effectiveness of OTN,in the worst case,it increases the bandwidth utilization of OTN by 50%.更多还原
