Hyper node torus: A new interconnection network for high speed packet processors
Atefeh Khosravi, Siavash Khorsandi, Mohammad Kazem Akbari · 2011
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.
