增强光传输网络的灵活性是支持基于分组的网络中的动态业务负载的关键要求。如今，通过静态点对点传输连接链接的分组交换机实现了灵活性。广泛的同步模式、线路编码方案和前向纠错(FEC)帧在传输层禁止灵活性。我们引入了一种新的光传输概念，它将分组聚合与多点对点线路编码和前向纠错处理相结合。该概念避免了诸如波长交换之类的其他聚合交换技术的二次全网状可伸缩性问题。它结合了分布式以太网交换机的灵活性和前沿光纤传输系统的性能。
Enhanced flexibility in optical transport networks is a key requirement to support dynamic traffic load in packet-based networks. Today, flexibility is achieved by packet switches linked by static point-to-point transport connections. Wide-stretched synchronization patterns, line coding schemes, and forward error correction (FEC) frames prohibit flexibility right at the transport layer. We introduce a new optical transport concept that combines packet aggregation with a multipoint-to-point line coding and FEC processing. This concept avoids the quadratic full mesh scalability problem of other aggregated switching technologies such as, e.g., wavelength switching. It combines the flexibility of a distributed Ethernet switch and the performance of a leading edge optical transport system.
