A METHOD AND ARRANGEMENT IN A COMMUNICATION NETWORK FOR SELECTING NETWORK ELEMENTS

摘要

An arrangement and method for selecting one or more network elements of a communication network from which a requested content is to be downloadable to a requesting host is based on an enhanced DNS functionality which is adapted to provide an optimized network element selection. A received address resolving request results in a process for selectively identifying and acquiring topology related network information, which is using the acquired information as a basis for selecting one or more network elements. Addresses are then resolved for the selected network element/s, and the obtained addresses are provided to the requesting host in response to the request.
