Abstract
A fast query method for a mobile network entity dynamic location information, using a distributed container hierarchical nested structure to process registration and queries for location information, includes: after a network entity connects to a network attachment point after moving and obtains a new network address assignment, determining a series of a registered container, and then registering new location information corresponding to where the network entity is currently located, the location information containing at least current network address information; when a network forwarding device learns that the network entity is currently un-reachable, querying the new location information of the network entity from the container where the network entity was located before moving; and the container where the network entity was located before moving, after receiving the query request, obtains the new location information of the network entity by searching in the container and in a peer neighboring container set.
