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.

The invention relates to the router design and research field of the mobile wireless self-organized network, which is more particularly characterized by including the flowing steps sequentially: the initial TTL values of the IP messages sent by all nodes are set to be 64. When the node sends an IP message, a router stored to a target IP is only sent to a next corresponding hop, or floods the messages to all the neighbors. When the node receives the IP message, the retransmitting hop times passed by the message can be analyzed according to the current TTL value of the message, and the shortest path to the source can be determined by combining the corresponding routing items of the node. The non-shortest routing produced in the process of flooding can be deleted for overtime as no corresponding IP message is transmitted. The invention realizes a novel rapid and simple Ad Hoc path-finding method with low protocol bandwidth consumption.

A method of designing an integrated circuit, by generating a first netlist for a first router design tool, abstracting the first netlist to mask selected old routes, and generating a second netlist for a second router design tool using new routing information which excludes the masked old routes. In an exemplary use, the first routing tool is an older tool, while the second routing tool is a newer tool that can provide a more compact database and more efficient routing. The first routing tool may use a format (e.g., ASCII) which is different from the format used by the second router design tool (e.g., binary). In such a case, the channel abstraction may involve extracting all channel routes from the first format, and converting the extracted channel routes into the second format. New routes can be established using the second router design tool based on the second netlist, while preserving other old routes. Abstraction can be achieved by removing from the first netlist selected logic cells which are to be interconnected by the new routes.
