    • PROBLEM TO BE SOLVED: To connect Ethernet (R) to SONET (Synchronous Optical NETwork) by redundant structure. SOLUTION: The network connection device is constituted as the redundant structure by link aggregation over the boundary between the Ethernet (R) and the SONET by providing mapping/demapping parts 34, 36 each of which performs mapping/demapping of EOS (Ether Over SONET) frame in the middle of a plurality of links made redundant using the link aggregation of the Ethernet (R) and performing collection and distribution frames for the EOS frame in an EOS integration part 38 provided on the SONET side.

    • 要解决的问题:通过冗余结构将以太网(R)连接到SONET(同步光网络)。 解决方案:通过提供映射/解映射部件34,36,通过在Ethernet(SONET)和SONET之间的边界上的链路聚合来将网络连接设备构成为冗余结构,每个映射/解映射部件执行EOS(Ether 在多个链路的中间,使用以太网(R)的链路聚合进行冗余并且在设置在SONET侧的EOS集成部分38中执行用于EOS帧的收集和分配帧的多个链路中的帧)。 版权所有(C)2010,JPO&INPIT
