Reduction of administrative overhead in maintaining network information, rapid convergence on an optimal routing path through the data network, and utilization of only required network resources are realized by a novel method for establishing a call path between network users. The method is based upon deployment of a network information server that stores network topology information and that is addressable by each end user. In this method, the network information server receives a request to establish a call path. The request identifies at least the calling party. In response to the request, the network information server determines a network traversal between the calling party and a root network wherein the network traversal includes call path information about the sub-networks between the calling party and the root network. The request for establishing a call path can also identify the called party. Based on the calling and called party identification, the network information server also determines a second network traversal between the called party and the root network. The second network traversal is sent to either the calling party or the called party or to both the calling and called parties. The server can determine an intersection of the traversals and send the intersection information to the parties. The intersection information is known as a merge point and represents an optimal call path between the parties.

The present invention provides a method and a system for handling content requests initiated by mobile wireless devices or content providers servers, implemented within a proxy server. Said method and system comprise of the steps: analyzing request type according to predefined business logic rules; identifying the relevant backend information server resources required for executing said request; connecting to the respective information servers; requesting and receiving the relevant information form the respective information servers; and forwarding the received information to content provider server.

Information services may be provided to a user of a personal digital assistant (PDA) via an infra red wireless communication port. The PDA recruits communication with a peer, such as a beacon, via this link, and the PDA and peer exchange messages containing the URLs of their proxies within the Internet. The proxies contact each other and negotiate, via the exchange of XML documents, parameters governing exchange of messages via the infra red link, such parameters being related inter alia to technical aspects of communication (e.g. file size, software compatibility etc.), encryption (e.g. public key information), and policy, which determines what the IR wireless link may be employed for, such as what content is sought. Negotiation between proxies is relatively rapid due to the higher bandwidth of the link between them in comparison to the IR link.
