摘要： Embodiments of the present invention route a wavelength division multiplexed signal across multiple communication paths using skew characteristics of at least some of the communication paths. The network is a wavelength division multiplexed optical transport network. The plurality of communication paths involves different signal and path attributes such as a plurality of carrier wavelengths, optical carrier groups, physical communication paths (different nodes, different fibers along a same path, or any combination of the foregoing), or any other differentiating factors between two paths.

摘要： Client signals to be transported in a transmission network, particularly an optical transmission network, may have different payload envelope rates and are digitally mapped on the client egress side into first transport frames (also referred to as iDTF frames, or intra-node or internal digital transport frames), at the client side for intra-transport within terminal network elements (NEs) and further digitally mapped into second transport frames (also referred to as DTFs or digital transport frames) for inter-transport across the network or a link which, through byte stuffing carried out in the first transport frames so that they always have the same frame size. As a result, the system of framers provides for a DTF format to always have a uniformly universal frame rate throughout the network supporting any client signal frequency, whether a standard client payload or a proprietary client payload, as long as its rate is below payload envelope rate of the client signal. At the client signal ingress side, the signal are digitally demapped from the second transport frames (DTF format) into the first transport frames where the stuff bytes are removed and accordingly processed at an intermediate node element before further transport, or digitally demapped from the first transport frames (iDTF format) to reproduce or reassemble the client signal or signals comprising the client payload at the client payload envelope rate for reception at the client's equipment. Among various features disclosed, two predominate features are (1) a single channel or network rate for transport of all signals between network elements (NEs) and end terminal network elements and (2) the digitally wrapping of different types of payloads into N client side or first frames using stuff bytes to render each client side frame size equal to a predetermined value. Then the stuffed first frames are wrapped into line side or second frames for transport over the network at the same high speed line rate for all digitally wrapped client signals. The client side framers may be, for example, running at the lowest signal rate encountered, to digitally wrap then into parallel N client signals or digitally wrap a client signal multi-sected into N parts, where these two different client signals have different payload rates.
摘要翻译：要在传输网络，特别是光传输网络中传输的客户端信号可以具有不同的有效载荷包络速率，并且在客户端出口侧被数字地映射到第一传输帧（也称为iDTF帧，或节点内部或内部数字传输帧），在客户端用于在终端网元（NE）内进行内部传输，并进一步数字地映射到第二传输帧（也称为DTF或数字传输帧），用于通过网络进行跨传输，或链路，通过在第一个传输帧中执行的字节填充，使得它们总是具有相同的帧大小。因此，成帧器系统提供了一种DTF格式，在整个网络中始终具有统一的通用帧速率，支持任何客户端信号频率，无论是标准客户机有效载荷还是专有客户端有效载荷，只要其速率低于有效载荷客户端信号的速率。在客户端信号入口端，信号从第二传输帧（DTF格式）被数字地解映射到第一传输帧中，其中填充字节被去除，并且在进一步传输之前在中间节点元素处进行处理，或者从第一传输帧进行数字解映射传输帧（iDTF格式）以客户端的有效载荷包络速率再现或重新组合客户端信号或包括客户端有效载荷的信号，以便在客户端的设备处接收。在所公开的各种特征中，两个主要特征是（1）用于在网络元件（NE）和终端终端网络元件之间传输所有信号的单个信道或网络速率，以及（2）将不同类型的有效载荷数字地包装到N个客户端或使用填充字节的第一帧来呈现每个客户端帧大小等于预定值。然后，填充的第一帧被包装成线路侧或第二帧，以便以相同的高速线路速率在网络上传输用于所有数字包装的客户端信号。客户侧构造器可以例如以遇到的最低信号速率运行，以数字方式将其并入N个客户端信号，或将多个客户端信号数字地包围N个部分，其中这两个不同的客户信号具有不同的有效载荷率。

摘要： A system, apparatus and method are described for controlling the gain across one or more amplifier nodes within an optical span. In one embodiment, a fast local amplifier constant gain control loop is provided that maintains a constant gain across an amplifier node for each of the channels within an optical signal. A slow link level gain setting control loop is provided to set and/or adjust the target gain on the amplifier node(s). A gain adjust sequence is performed by the slow link level gain setting control loop to adjust the target gain(s) in response to various events and mechanisms. A "time of flight" protection method is also provided to ensure consistency between the fast local amplifier gain control loop and the slow link level gain setting control loop.
