Abstract: A method for virtual object interaction. The method includes: receiving, by a server, an interaction instruction from a client to instruct multiple first virtual objects to interact with a target virtual object; creating, by the server, one or more mirror objects of the target virtual object, a sum of the number of the one or more mirror objects and the number of the target virtual object being the same as the number of the multiple first virtual objects; calculating, by the server, interaction data of interactions between the multiple first virtual objects, and the target virtual object and the one or more mirror objects; and synchronizing, by the server, first attribute data of the target virtual object and first attribute data of the one or more mirror objects based on the interaction data, and sending the synchronized first attribute data to the client.

Abstract: The present invention relates to IP network communication technology. It provides a kind of IP multicast data layer distribution method and system. The method includes: first code original multicast data into multiple sub-flow, separately specify different shunt sub-source for every sub-flow, distribute sub-group address, create sub-group state, etc, form shunt structure. Then the sink send join news to each shunt sub-source, join each shunt sub-source sub-group and become the leaf node of each sub-tree. And then each shunt sub-source determine the intermediate node according to the port receiving join news and construct multicast distribution-tree. If the overlapping portion between the multicast distribution trees produce congestion, in the congestion nodes network coding is used to eliminate congestion and construct coding sub-tree according to the way of building multicast distribution tree from the below of the coding nodes.
