Selecting data interfaces in a multi-homing communication device

The invention claims a host in a network device and data network between the transmitting and receiving data method and said method comprises defining network policy and said network policy is transmitted to the route module. The said method comprises the said route module receives the route range. The said route range and identifying it satisfies the requirement of the said network policy to said data network data interface of the subset wherein the data interface of electronic subassembly is selected from a group of which can be used for data interface and wherein said data interface the group comprising at least one data interface.
