摘要： Methods and systems are provided for controlling elements in a signal path of a communication network to accommodate changes in the rate of a client signal. In particular, during the bandwidth resizing (BWR) portion of ITU-T Recommendation G.7044 Hitless Adjustment of ODUflex(GFP) protocol (HAO), the nodes in the chain along the ODUflex(GFP) signal path change their output rates in parallel such that FIFO over/underflow is avoided in the nodes. Certain embodiments provide mechanisms to synchronize and stabilize the nodes in a verifiable manner.

摘要： A method and apparatus are described for signaling the phase and frequency of constant bit rate (CBR) clients over a network or fabric. An incoming CBR client stream is segmented into variable sized segments, such as packets or general framing protocol (GFP) frames, and is regenerated on the other side of a fabric or network phase-locked to the incoming stream. Regeneration of the CBR client clock is based solely on segment sizes, and in the case of GFP frames, the rate of the SONET Path or OTN ODUk stream carrying the GFP frames. No overhead bytes are inserted into the GFP frames to convey phase and frequency information. The method disclosed is important for reducing the cost and complexity of communications networks by allowing CBR clients to be transported with low jitter and wander without requiring the source and sink network elements to be phase-locked to a common stratum reference.
摘要翻译：描述了一种用于通过网络或结构信令恒定比特率（CBR）客户端的相位和频率的方法和装置。传入的CBR客户端流被分段成可变大小的段，例如分组或通用帧协议（GFP）帧，并且在被锁定到输入流的结构或网络的另一侧上重新生成。 CBR客户端时钟的再生完全基于段大小，在GFP帧的情况下，是携带GFP帧的SONET路径或OTN ODUk流的速率。 GFP帧中没有插入开销字节来传送相位和频率信息。所公开的方法对于通过允许CBR客户端以低抖动和漂移传输而不需要将源和接收网络元件锁相到公共层参考来减少通信网络的成本和复杂性是重要的。
