Problems solved by technology

Since the broadcast causes the inspection frame to be published on all VLAN ports, the unicast information intended to be a specific domain becomes the broadcast information in the entire VLAN, thereby causing a potential security violation by breaking the separation of OAM domains

Embodiment Construction

[0020] Embodiments of the invention are now described with reference to various examples of how the invention is best made and used. Like reference numerals are used to designate like or corresponding parts throughout the description and several views of the drawings, wherein the various parts are not necessarily drawn to scale. Referring now to the accompanying drawings, in particular figure 1 , described here is an embodiment of an end-to-end Ethernet OAM network 100 with multiple OAM domains, in which a solution for reducing OAM frame leakage according to an aspect of the present invention is provided. As shown, the Ethernet OAM network 100 includes a layered network environment including a first user equipment network 102A and a second user equipment network 102B forming part of its terminal, the first user equipment network 102A and the second user equipment network 102A Device network 102B is connected to core transport network 108 through respective access networks 106...

Abstract

A system and method for reducing frame leakage in a VLAN defined in an Ethernet OAM network. Upon receiving a unicast OAM frame at a Maintenance Intermediate Point (MIP) entity, a first database is queried to verify it the frame's destination address (DA) is provided therein. If not, a second database is queried to verify the frame's source address (SA) is associated with a Maintenance End Point (MEP) entity provided therein. If so, OAM domain level information corresponding to the MEP entity is obtained and a multicast MAC address associated with the OAM domain level is determined. The incoming OAM frame's DA is then replaced with the multicast MAC address for forwarding the frame to a set of port addresses restricted to the OAM domain level.
