摘要： Embodiments of the present invention provide a method and system for reserving a connection's home path resources and restoring the connection on a link that includes a reserved priority bandwidth. A bandwidth advertisement indicating that the reserved priority bandwidth is available is analyzed and a restoration request requesting to route the connection on the link is sent. The reserved priority bandwidth is used to route the connection when the connection has a reserved home path on the link. When the connection has a reserved home path not on the link, a determination is made as to whether a normal priority bandwidth on the link is available and whether the connection is unrestorable on another link. The reserved priority bandwidth is used to temporarily route the connection when normal priority bandwidth on the link is unavailable and the connection is unrestorable on another link.

摘要： A method and system for determining timers in a High Level Data Link Control (HDLC) Traffic Manager (HTM) state machine are disclosed. According to one aspect, the invention provides for determining a transit delay between two nodes by sending a first packet having a delay measurement byte to a second node that is on a link between the first node and the second node. A measured delay value is determined based on the delay between a time of sending the first packet to the second node and receiving a second packet from the second node. The timer values of the HTM state machine are set based on the measured delay value.

摘要： The present disclosure provides Network Element (NE) clock synchronization using Optical Transport Network (OTN) delay measurement systems and methods such as described in ITU-T G.709 (December 2009) “Interfaces for the Optical Transport Network (OTN)” and G.798 (October 2010) “Characteristics of optical transport network hierarchy equipment functional blocks”. OTN provides a Delay Measurement (DM) function to measure fiber path latency between two network elements to within microsecond accuracy. The convergence of packet switching and OTN transport into the same network element allows the sharing of this information between the two applications. The OTN delay measurement value can be used to synchronize two network element clocks to within microsecond accuracy without the need for a costly GPS synchronization solution or reduced accuracy NTP solutions.

摘要： The present disclosure provides systems and methods for inserting pseudo-noise in a data stream based on an unacceptable input data sequence in an optical network thereby preventing unnecessary loss of frame in SONET/SDH or Optical Transport Network (OTN) systems. The present disclosure includes a SONET/SDH or OTN framer, a transceiver, and a method for detecting an unacceptable data sequence or pattern and inserting a keep-alive or pseudo-noise sequence in the data sequence to maintaining framing on subsequent network elements, framers, transceivers, etc. For example, the present invention, upon receiving an unacceptable pattern of zeros or low ones density caused by a loss of signal condition or the like, may insert a pseudorandom noise pattern into the transmitted frame. This allows the downstream network element to continue a frame lock on the incoming signal, and thus keep the frame overhead and data communications channels from being lost.
摘要翻译：本公开提供了用于在光网络中基于不可接受的输入数据序列在数据流中插入伪噪声的系统和方法，从而防止SONET / SDH或光传输网络（OTN）系统中的帧的不必要的丢失。本公开包括SONET / SDH或OTN成帧器，收发器和用于检测不可接受的数据序列或模式以及在数据序列中插入保持活动或伪噪声序列以在后续网络元件，成帧器，收发机等。例如，本发明在接收到由信号条件等的丢失引起的不可接受的零或不足的密度模式时，可以将伪随机噪声模式插入发送的帧中。这允许下游网络元件在输入信号上继续帧锁定，并且因此保持帧开销和数据通信信道丢失。

摘要： An Optical channel Data Unit flex (ODUflex) resizing method, node, and network include determining that the ODUflex needs resizing, wherein the ODUflex is configured in the network on a current path between the node and a second node in the network; when the resizing is a decrease, reducing a size of the ODUflex by i) a resize decrease operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation; and, when the resizing is an increase, increasing a size of the ODUflex by i) a resize increase operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation. The method provides hitless resizing without using ITU Recommendation G.7044/Y.1347 (10/11) and can perform the reducing or the increasing changing bandwidth of the ODUflex by approximately 100 G in less than a second.

摘要： The present disclosure provides Optical Transport Network (OTN) port protection systems and methods using flexible switch criteria. Specifically, the OTN port protection systems and methods provide linear protection in OTN such as 1+1 Protection with Automatic Protection Switching (APS) and/or 1+1 Subnetwork Connection Protection (SNCP) Protection. The OTN Port Protection with flexible switch criteria allows a user to provision a protection application on an OTN Port and select a switch criteria, Section Monitoring, Path Monitoring, or Tandem Connection Monitoring, without considering the provisioning state of an Optical channel Data Unit level k (ODUk) entity. The ODUk entity may either be cross-connected in the LO case or terminated in the HO case. The ODUk entity may be provisioned independently, after the port protection has been established.
