The system can include a Provider Backbone Bridge (PBB) interface or interfaces configured to receive a plurality of data stream types each associated with an Instance Service Identifier (I-SID) from a Metropolitan Area Network (MAN) or public carrier Ethernet. A plurality of local area network (LAN) ports can be configured to communicate data to a plurality of LANs. A switching process is provided between the PBB interface and the LAN ports. The switching process can be configured to bind individual data stream types from subdivided data streams each represented by an I-SID to each of the respective LAN ports. In addition, the switching process can communicate packets between the PBB interface and the bound LAN ports."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method to provide multiple private networks using PBB","description":"A system and method are supplied to provide multiple private networks.
