摘要： A method of managing a ring network. Bandwidth utilization metrics indicative of traffic flows within the network are derived. An optimal seam location is calculated based on the bandwidth utilization metrics. A channel block can be implemented at the calculated optimal seam location. The optimal seam location can be selected to balance traffic flows in the network, and can be updated as the distribution of traffic evolves over time.

摘要： A Carrier Ethernet method includes receiving a request to initiate an Ethernet Operations, Administration, and Maintenance (OAM) session at a local device, setting up the OAM session at the local device responsive to the request, transmitting a Protocol Data Unit (PDU) from the local device to a remote device with information related to the OAM session and the request contained therein, and receiving the PDU at the remote device and setting up the OAM session at the remote device based on the information in the PDU. The OAM session can include Ethernet Frame Loss Measurement and can be initiated only at the local device without requiring operator involvement at the remote device

摘要： Systems and methods with dynamic Connectivity Fault Management (CFM) and Continuity Check Messages (CCMs) that enable dynamic configurations to avoid limitations associated with static reconfigurations. Variously, a network, a method, and a network element are configured to implement a dynamic CFM method for dynamic notifications and actions taken based thereon between Maintenance End Points (MEPs). The systems and methods may also include a CCM attribute adjustment method between two MEPs, a CCM suspension and/or resumption method between two MEPs, and a MEP auto-discovery and leaving method. Advantageously, the systems and methods may be utilized in a variety of contexts including controlled maintenance, in-service software upgrades, network congestion, discovery of new remote MEPs, and the like to enable dynamic configurations between MEPs. The systems and methods may also apply to Carrier Ethernet, Multiprotocol Label Switching-Transport Profile (MPLS-TP), and the like.

摘要： Systems and methods for ring protection switching in a network based on selectively blocking and unblocking a port include forwarding traffic via the port over a data channel that utilizes a first service identifier, wherein the data channel is routed in the network along a closed loop; and selectively blocking and unblocking traffic on the port to provide the ring protection switching over the closed loop, wherein the selectively blocking and unblocking is performed based on a management channel that utilizes a second service identifier that is a different type from the first service identifier.

摘要： A node includes a first port configured to be selectively blocked and unblocked; a second port configured to be selectively blocked and unblocked; a forwarder between the first port and the second port; a management channel between the first port and the second port, wherein the selective blocking and unblocking of the first port and the second port is based on the management channel; and a data channel between the first port and the second port, wherein the data channel utilizes an arbitrary service identifier. A method can include operating a ring with Ring Protection Switching comprising a forwarding mechanism and a blocking mechanism that are independent and decoupled entities therebetween, wherein the ring includes a management channel and a data channel that each utilize an arbitrary service identifier.

摘要： A method and system provide in-band protection switch signaling in a communication system arranged as a point-to-multipoint tree. The point-to-multipoint tree includes a root node communicatively coupled to a plurality of leaf nodes through both a working link and a protection link. Data is transferred through a current link of the point-to-multipoint tree. The current link is either the working link or the protection link. A fault is detected in the current link in the point-to-multipoint tree. Each leaf node in the point-to-multipoint tree is notified of the fault using the current link. Upon receiving the notification, the root node and each leaf node switch to the other link of the working link and the protection link.
