A forwarding method and system for data broadcast reduction in a Vehicle Named Data Networking (VNDN) is proposed. The method includes (a) setting name centrality (NameCent) count data with respect to an interest packet received by a node of the VNDN; (b) measuring, by a Received Signal Strength Indicator (RSSI), a power level of signal received from an access point (AP) or any other vehicle in wireless communication; (c) calculating a weight of the interest packet for a data forwarder in a current node or a previous node based on the name centrality (NameCent) count data and signal strength measured by the Received Signal Strength Indicator (RSSI); and (d) determining a potential forwarder of a data packet by comparison of variables of the weight calculated in step (c).

Forwarding method and system for data broadcast reduction based on name centricity and applied in vehicle named data networking

The present invention relates to a system and method for protecting a virtual circuit in a dynamic multi-domain environment, the system comprising: a request agent (RA) for transmitting, if a network service is requested from a user terminal, a network resource allocation request signal for providing the requested network service to a global network service agent (NSA); the global network service agent (NSA) for managing at least one or more provider NSAs existing in one composition domain and managing data plane status information of primary/backup virtual circuits of each domain on the basis of information received from the at least one or more provider NSAs; and the at least one or more provider NSAs for configuring, according to reception of the network resource allocation request signal, a network device and the primary and backup virtual circuits, monitoring whether a failure occurs in the configured virtual circuits and network device, and transmitting link/node failure/recovery information and protection/regeneration success/failure information to the global NSA.
