Patent number: 10623293Abstract: 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.Type: GrantFiled: January 7, 2016Date of Patent: April 14, 2020Assignee: Ciena CorporationInventors: Jie Hu, Marc Holness, Cory Gordon, Mradula Neginhal, Madhavi R. Joshi, Asheesh Jadav

Patent number: 10142203Abstract: Ethernet fault management systems and methods using programmable Type-Length-Value (TLV) offsets combine software-based Operations, Administration, and Maintenance (OAM) protocol support with hardware-based fault management support to delegate generation and processing of OAM protocol messages to hardware devices with the software-based protocol support used to program hardware based on fixed offsets in the OAM protocol messages. The hardware can be designed to be flexible since the hardware can be agnostic to the logic within the OAM protocol which would reside in the software. The Ethernet fault management systems and methods combine the flexibility of software-based approaches with the speed and efficiency of hardware-based approaches.Type: GrantFiled: February 19, 2016Date of Patent: November 27, 2018Assignee: Ciena CorporationInventors: Asheesh Jadav, Cory D. Gordon, Madhavi R. Joshi, Venkata Satya Mahesh Jetti, Sri Siri Vineela Kukkadapu, Kelly D. Fromm
