System And Method For Correlating Carrier Ethernet Connectivity Fault Management Events
First Claim
1. A computer-implementable method for managing network connectivity faults, comprising:
- generating a first set of network device information related to a first receiving managed endpoint (MEP) failing to respond to a multicast message broadcast by an originating MEP within a predetermined period of time;
processing the first set of network information to generate a first set of MEP network event information;
generating a second set of network device information related to a second receiving managed endpoint (MEP) failing to respond to the multicast message within the predetermined period of time;
processing the second set of network information to generate a second set of MEP network event information; and
performing comparison operations between the first and second sets of MEP network event information to determine if said second MEP network event is a child of said first MEP network event.

Abstract
A method, system and computer-usable medium are disclosed for suppressing managed endpoint (MEP) child events in a network. A MEP multicast message is broadcast by an originating MEP. Responses received from peer MEPs within a selected time interval are processed to determine their respective IP address, MAC address, and VLAN. If this information is not currently stored in a table of peer MEP device information associated with the originating MEP, then it is added. The responding MEP is then marked in the peer MEP device table as having responded. Peer MEP devices that have responded to previous multicast messages, but have now failed to respond within the selected time interval, are determined. A MEP network event is generated, comprising the IP address of the device containing the MEP, the MAC address for inward-facing MEPs, the MAC address of the associated bridge, the port addresses for outward-facing MEPs, and associated VLAN information. If another MEP network event occurs, the MAC address of the MEP and its VLAN information is determined. If the VLAN associated with the current MEP network event contains a MAC address associated with a prior MEP network event, then the MEP network event is designated as a child MEP network event and suppressed. Otherwise, the MEP network event is designated as a parent MEP network.
