Abstract
Systems and methods for sinking port mirrored from one or more identified flows of data to any node in a network are provided. Moreover, the network is configured to convey the mirrored data to the sink, without the need for any facilities expressly dedicated for this purpose. The present invention removes the requirement to co-locate the sink port within the same logical node. The present invention uses a mirrored flow configured as a provisioned layer two point-to-point connection, such as a Switched Permanent Virtual Circuit (SPVC), Pseudo-Wire (PWE3), a Virtual Local Area Network (VLAN) cross-connect, Provider Backbone Bridging-Traffic Engineering (PBB-TE), and the like. The node with the mirrored port is configured to create copies of the appropriate set of packets (i.e., ingress, egress packets, or both based on provisioning and based on the identified flow), and to forward the packets to the sink port through the provisioned point-to-point connection.
