Abstract
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.
