Method for optimal path selection in traversal of packets through network address translators

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.

Software configurable cluster-based router using heterogeneous nodes as cluster nodes

A cluster router architecture and methods for performing distributed routing are presented. The cluster router architecture includes off-the shelf Personal Computer (PC) hardware-based router cluster nodes interconnected in an intra-connection network in multiple dimensions. Each PC-based router cluster node is provided with the same routing functionality and a router-cluster-node-centric configuration enabling each router cluster node by itself or multiple router cluster nodes in the cluster router to provide routing responses for packets pending processing. Optimized packet processing in respect of specific functionality is provided via special purpose router cluster nodes not necessarily PC-based taking part as cluster nodes in the cluster router lattice. The method divides packet processing into entry packet processing and routing response processing; special processing; and exit processing. Entry packet processing and routing response processing is performed by router cluster nodes receiving packets from communication networks in which the cluster router participates. Exit packet processing is performed by router cluster nodes transmitting packets into communication networks in which the cluster router participates. Packet processing in accordance with the router-cluster-node-centric specification is interrupted on determining that special processing is required in respect of a packet, and the packet is handed over to a corresponding special purpose router cluster node. Advantages are derived from: a configurable, and scalable cluster router design providing a re-configurable high routing capacity using cost effective stock PC hardware; from the intra-connection network which provides a high degree of diversity ensuring resilience to equipment failure; from the use of a star topology with respect to management links which reduces management overheads in the intra-connection network; and from the ability to forward packets to designated special purpose router cluster nodes optimized to provide specific packet processing functionality.

Method for restricting access to a web site by remote users

A method of restricting access to data maintained on a server computer by one or more authorized, networked client machines includes the step of installing a client-side software program on the client machine for generating a client machine-specific identifier determined by particular characteristics of the client machine. The machine-specific identifier is used by the server administrator to generate a unique password, which the user enters into the client-side software program. Server-side software is embedded on protected Web pages of the server computer that hosts the protected Web site. When a user desires access to protected content, the client-side software is prompted to re-generate its machine-specific identifier and valid client password list for comparison with the password previously entered by the user. Access is granted if they correspond, and denied if they do not. If the client machine is recognized as being authorized to access data on the protected Web site during a first access request, then the current session identifier is saved in a temporary storage table remote from the client machine for indicating current working sessions of authorized client machines. The client machine returns such session identifier with each additional request for access, and the temporary storage table is consulted to search for such session identifier before granting access.
