GPON OAM using IEEE 802.1ag methodology

摘要

Operations, administration and management (OAM) functions in a passive optical network (PON) can be performed by providing a system of flow points (i.e., software entities), such as those along the lines of the Maintenance End Points (MEPs) and Maintenance Intermediate Points (MIPs) described in the IEEE 802.1ag specification, which communicate connectivity fault test messages with each other. The flow points can be provided in the Optical Line Terminal (OLT) and Optical Network Terminator (ONT). Alternatively or in addition, flow points can be provided in a subscriber gateway coupled to the ONT. The flow points issue test messages, to which other flow points can respond with information regarding the state of network connectivity.

1. A connectivity fault management system coupled via a passive fiber network (PON) to an optical interface, the system comprising:
a processor operable to configure a single segment of the PON, comprising an Optical Line Terminal and an Optical Network Terminator connected to a single optical interface of the PON, as: a plurality of subscriber levels in the same domain, each level comprising a plurality of Maintenance End Points (MEPS) and Maintenance Intermediate Points (MIPs), and each MEP within a subscriber level operable to exchange connectivity fault test messages with MEPs on the same subscriber level that are associated with corresponding PON logical data paths identified by port identifications (Port-IDs) within an exchanged connectivity fault test message and MIPs.
