1. A wireless communication device as a device package including a network device, a wireless base station, and one or more devices connected to the network device,
the wireless communication device comprising:
a plurality of surfaces that are a plurality of logical network sections; and
a control device that is connected to the network device;
wherein the one or more devices include a server device that is one or more computers connected to the network device;
the network device has a plurality of first network interfaces (NW-IFs) that are a plurality of interfaces connected to the server device, and a second NW-IF that is an interface connected to at least one of a network and the wireless base station and that is an interface connected to any one of the plurality of first NW-IFs;
wherein the server device has a plurality of applications, each of which inputs and outputs data, a plurality of network namespaces, each of which is a basis for data transfer, and a plurality of server interfaces (SV-IFs) that are a plurality of interfaces connected to respective ones of the plurality of first NW-IFs;
each of the plurality of surfaces includes a set of elements that includes an application of the plurality of applications, a network namespace of the plurality of network namespaces, an SV-IF of the plurality of SV-IFs, and a first NW-IF of the plurality of first NW-IFs, wherein, for each of the plurality of surfaces, no elements in the set of elements for the surface are used as elements of a surface other than the surface;
the control device has, for each of the plurality of surfaces, surface management information including information related to the surface; and
the control device selects a surface conforming to conditions from the plurality of surfaces on a basis of the surface management information and a namespace of the plurality of network namespaces being included in the surface, the surface having different network characteristics than the other surfaces, and causes the network device to execute surface switching for connecting the second NW-IF to the first NW-IF of the plurality of first NW-IFs in the selected surface.
