Efficient Batch Update of Unique Identifiers in a Distributed Hash Table for Resources in a Mobile Host
Source: Cornell University
Resources in a distributed system can be identified using identifiers based on random numbers. When using a distributed hash table to resolve such identifiers to network locations, the straightforward approach is to store the network location directly in the hash table entry associated with an identifier. When a mobile host contains a large number of resources, this requires that all of the associated hash table entries must be updated when its network address changes. The authors propose an alternative approach where they store a host identifier in the entry associated with a resource identifier and the actual network address of the host in a separate host entry.
