Abstract
One embodiment of the present invention provides a system that facilitates traffic isolation (TI) in a network. During operation, the system configures a set of switch ports as members of a TI zone. The switch ports are part of an end-to-end path across one or more switch domains between a source and a destination. The switch ports within the TI zone and outside the TI Zone belong to a common storage area network (SAN) zone which compartmentalizes data for security purposes. The system then determines whether a data flow entering a switch domain belongs to the TI zone. The system subsequently forwards the data flow to the next port within the TI zone if the data flow belongs to the TI zone.
