- Abstract
- The present invention provides a lightweight multicast method and apparatus for a data distribution service. The lightweight multicast apparatus includes a network congestion detection unit for multicasting packets to a plurality of subscriber node terminals, and detecting a cause of network congestion using a negative response message transferred from a relevant subscriber node terminal that could not receive the packets among the plurality of subscriber node terminals. A network recovery control unit determines a recovery control policy depending on the cause of the congestion detected by the network congestion detection unit, and solves the cause of the congestion.
