|Title:||NETWORK SYSTEM, MANAGEMENT METHOD AND DEVICE FOR SAME, AND SERVER|
[Problem] To provide a management method, a management device, a server and a network system with which it is possible to perform network management including VNF migration, in a network in which a programmable logic circuit is included as a VNF infrastructure. [Solution] A management device (10) includes: a storage means (103) for associating and storing at least one virtual network function (VNF) operating on a server, with a programmable logic circuit (FPGA) serving as an operating entity of at least part of the virtual network function; and a control means (106) for causing a first server and a second server to execute a migration, on the basis of the associated information, to cause the virtual network function operating on the first server using the programmable logic circuit to migrate to the second server.
