The invention discloses a network architecture supporting configuration and a service response method. The network architecture comprises a service decomposition module, a route addressing module anda processing and forwarding module. The service decomposition module, the route addressing module and the processing and forwarding module all support a network manager to configure according to needs, the service decomposition module decomposes a service request into a service request, and a corresponding relationship between a service type and the service request can be configured in the servicedecomposition module; the routing addressing module converts the service request into a routing and addressing mode, and service and transmission paths provided by each node can be configured in themodule; the processing and forwarding module converts a routing and addressing mode into a resource allocation mode, and the resource allocation rule of each node can be configured in the module. At each stage of responding to the service request, the configuration can be carried out as required, so that the adaptation degree of the service request and network resources can be improved to the greatest extent.
