 BPNs can be implemented using a host of technology platforms, including but not limited to traditional EDI value-added networks (VANs), industry exchanges, B2B Gateways, point to point integration brokers, VPNs, and other mechanisms that enable trading partners to connect electronically, collaborate and conduct business amongst each other.BPNs are being further accelerated by growth in Web services and service-oriented architectures (SOA), technologies that simplify the integration of people, processes and systems.Business Process Networks are often managed using multi-tenant architectures to more rapidly enable seamless, many-to-many or one-to-many (hub-spoke model) connectivity between trading partners across the extended supply chain.
