摘要： An information system of the present invention includes a plurality of physical nodes each of which processes a packet received from external node(s) according to a processing rule (packet handling operation) that associates a matching rule for identifying a flow and processing content to be applied to a packet that matches the matching rule, and a control apparatus which sets the processing rule in each of the plurality of physical nodes, thereby causing the plurality of physical nodes to operate as virtual nodes on a virtual network(s) usable by the external node(s). The control apparatus includes a first storage unit defining a correspondence relationship between each of the plurality of physical nodes and virtual network(s), and a second storage unit defining a correspondence relationship between each of the external node(s) and virtual node(s) on virtual network(s). The control apparatus determines the virtual network(s) and the virtual node(s) to which the external node(s) is to be connected, based on information on the physical node(s) to which the external node is connected and information on the external node(s).

摘要： A packet forwarding system includes: first relay apparatuses that are connected to each other; a second relay apparatus that includes ports and that is connected to first relay apparatuses; and a control apparatus that configures a trunk serving as virtual logical link by using physical links among first and second relay apparatuses. The control apparatus determines a designated port from ports of first relay apparatuses included in the trunk. When a relay apparatus included in the first relay apparatuses receives a predetermined control target packet, the control apparatus controls the first relay apparatuses to transmit a received control target packet via relay apparatus having the designated port.
