Content-based centralized routing architecture mccn

The present invention relates to the field of network protocols. Disclosed is a content-based centralized routing architecture MCCN, consisting of a management layer, a control layer, and a data layer. The management layer is in communication with the data layer by means of the control layer; the management layer obtains application transfer requirements, network resource configurations, and network running statuses, and delivers a network operation instruction to a control plane according to a reconstruction management policy; the control layer establishes a route, maintains network topology of a domain, notifies the management layer of a network status, and executes the instruction from the management layer; the data layer correspondingly processes data packets according to the instruction from the control layer, and a task of the data layer is completed by a router and a link at an underlying layer. The present invention has the following advantageous effects: by dividing a service bearer network according to service requirements, underlying resources can be better utilized; and by delivering a path by a controller, mass transmission of Interest packets caused by flooding can be avoided, and the link utilization rate can be effectively improved.
