METHOD OF PACKET MARKING FOR FLOW ANALYTICS

摘要

A method is implemented by a node of a network domain having a plurality of nodes, where the node functions as an ingress node of the network domain for a data flow. The method enables data flow analysis across the network domain. The method includes receiving a data packet belonging to a data flow at an ingress node of the network domain, determining whether the data packet is to be marked for the data flow analysis, determining whether an egress node of the network domain for the data flow supports data packet marking, marking the data packet with a marking label indicating to supporting nodes in the network domain that the data packet is to be processed for data flow analysis, and forwarding the data packet toward the egress node of the network domain.

1. A method implemented by a node of a network domain having a plurality of nodes, where the node functions as an ingress node of the network domain for a data flow, the method to enable data flow analysis across the network domain, the method comprising the steps of:
receiving a data packet belonging to a data flow at an ingress node of the network domain; determining whether the data packet is to be marked for the data flow analysis; determining whether an egress node of the network domain for the data flow supports data packet marking; marking the data packet with a marking label indicating to supporting nodes in the network domain that the data packet is to be processed for data flow analysis; and forwarding the data packet toward the egress node of the network domain.
