<p>A mirroring configuration employs an alternate usage of an existing messaging protocol and mechanism for propagating mirroring control for remote mirroring of data streams. A source routing entity, i.e. a router or switch through which the mirrored stream passes, identifies the stream as available for monitoring. The enabled stream propagates from a source network device, typically from a router port, to a mirroring destination in addition to the addressed destination. A stream identifier emulates an identifier from an alternate usage, such as a multicast group identifier for a multicast protocol, and activates mirroring by inserting the stream identifier in publish and join messages of the multicast protocol.</p> |
