Abstract: The present invention relates to a system (1000) and method for 5 virtual network function (VNF) placement. The system (1000) comprises a user interface (100) for interfacing a network function provider and a user, a VNF manager (200) for registering VNFs, receiving and matching the VNF request, and initiating the VNF placement,migration and monitoring, a cloud management component (300) for identifying the VNF request, performing a VNF placement optimization, and provisioning the VNFs in a plurality of cloud nodes (700), a software-defined network (SDN) controller (400) for provisioning a network topology between the provisioned VNFs, the VNF provider (500) for providing network functions as software instance, a plurality of switches (600) for enabling SDN based cloud environment, and the plurality of cloud nodes (700) for storing the plurality of switches (600). The cloud management component (300) comprising a VNF placement optimizer (303) for performing placement optimization based on constraints data. Figure 1

Abstract: The present invention relates to a system and method for multicast forwarding over an OpenFlow based network that can save bandwidth and improve transmission efficiency. The system comprises an OpenFlow switch (100) and an OpenFlow controller (200) for managing the OpenFlow switch (100) using OpenFlow protocol. The OpenFlow controller (200) comprises a packet handler (201) for performing identification of a packet-in message, a mapping handler (202) for maintaining one or more multicast address tables, a node status handler (203) subscribing a node service module (206) for detecting location change of the nodes and port subscription, and a group table updater (204) for converting response data of a notification received from the packet handler (201) or the node status handler (203) into an equivalent action bucket. The method comprises the steps of receiving a packet-in message; and processing the packet-in message (301), thereby generating a packet-out message for transmission to the OpenFlow switch (309).
