Abstract
Provided are an apparatus and method of dividing virtual sites using policy properties in multiprotocol label switching (MPLS) networks. In this method, when multiple virtual sites are selected with respect to one interface, not only usually used source IP addresses and VLAN tags but also TOS fields and MPLS labels are used so that more various kinds of virtual sites can be selected. Also, since the TOS fields and MPLS labels can express additional QoS-related information, differentiated services can be provided by selecting a wider variety of kinds of virtual sites.
