Hyper node torus: A new interconnection network for high speed packet processors

Due to the significant growth of link speeds, amount of data that should be stored on router line cards are rapidly increasing. Therefore, a large number of memory modules are required for packet storage. In addition, a high performance interconnection network on line cards is strongly needed for inter-communication between processing elements and memory modules. In this paper we propose a new interconnection network, known as hyper node torus that can support larger number of nodes compared to other topologies, such as common torus network on a limited area. Simulation results show that hyper node torus can sustain more traffic load, and also it has higher throughput than the torus network under different traffic loads. As a result, it has better scalability and higher performance for using in high-speed packet processors.
