摘要： A method, performed in a network that includes a group of nodes, includes identifying a path through a set of the nodes, where each node, in the set of nodes, has a data plane and a control plane; establishing a control plane tunnel, associated with the path, within the control plane of the nodes in the set of nodes; establishing a data plane tunnel, associated with the path, within the data plane of the nodes in the set of nodes, where the data plane tunnel is associated with the control plane tunnel and established through the same set of nodes; and transmitting a control message through the control plane tunnel to change a state of the data plane tunnel.

摘要： Consistent with the present disclosure, a communication system is provided in which client data is received and provided in frames for transmission within the system. The frames include an overhead portion as well as locations that include the client data. The frames further include phase data or “virtual justifications” that periodically correct the difference between the phase represented by the data locations in the wrapper and the actual accumulated client phase. The phase data or virtual justifications, however, are decoupled from the data path. Therefore, without complicating the data path, the phase data may be sent more frequently and with finer granularity than the actual justifications. Virtual justifications or phase data are communicated via a “virtual justification control channel” which may part of the frame overhead. Moreover, there is no need for an actual “virtual justification opportunity” in the frame, because no data is actually sent in conjunction with the virtual justifications.

摘要： A propagation delay in the transmission of a frame from an initiator node to a peer node is determined by initially identifying a frame number and byte offset of a first incoming frame from the peer node at a time when the initiator node outputs a portion of a transmitted frame. The portion of the transmitted frame may be the first byte of a sub-frame within the transmitted frame. At the peer node, the frame number and byte offset of a second frame to be supplied to the initiator node is identified at a later time when the frame portion transmitted by the initiator node is received by the peer node, and such information is transmitted to the initiator node. Thus, since the frames output and received by the initiator node are typically of fixed duration, the frame number and byte offset of the incoming frame represent the time when the initiator node outputs the frame portion (a transmit time). In addition, the frame number and byte offset of the second frame represents the time at which the frame portion is received by the peer node (a receive time). Accordingly, by comparing the frame numbers and byte offsets of the first and second frames received from the peer node, a difference between transmit and receive times or propagation delay can be obtained.

摘要翻译： 通过在发起者节点输出发送的一部分的时间，首先识别来自对等节点的第一输入帧的帧号和字节偏移来确定帧从发起者节点传输到对等节点的传播延迟 帧。 发送帧的部分可以是发送帧内的子帧的第一个字节。 在对等节点，由发起方节点发送的帧部分由对端节点接收到的时候，识别要提供给发起方节点的第二帧的帧号和字节偏移，并将这些信息发送到 启动器节点。 因此，由于由发起者节点输出和接收的帧通常是固定持续时间，所以入局帧的帧号和字节偏移表示发起者节点输出帧部分的时间（发送时间）。 此外，第二帧的帧号和字节偏移表示对等节点接收帧部分的时间（接收时间）。 因此，通过比较从对等节点接收到的第一和第二帧的帧号和字节偏移，可以获得发射和接收时间之间的差异或传播延迟。

摘要： A line card in a network node having a local memory coupled to a local controller and local logic circuit. The local memory in the line card stores state information for signals processed by the line card itself, as well as state information for signals processed by other line cards. The logic circuit and controller implement a same fault detection and signal processing algorithms as all other line cards in the group, to essentially effectuate a distributed and local hardware based control of automatic protection switching (APS) without interrupting a central processor. The line card also performs error checking and supervisory functions to ensure consistency of state among the line cards.
