| Popis: | Data Center Networks (DCNs) have gone through major evolutionary changes over the past decades. Yet, it is still difficult to predict loads fluctuation and congestion spikes in the network switching fabric. Conventional multistage switches/routers used in data center fabrics barely deal with load balancing. Congestion management is often processed at the edge modules. However, neither the architecture of switches/routers, nor their inner routing algorithms tend to consider traffic balancing and congestion management. In this paper, we propose a flexible design of a scalable multistage switch with crossconnected UniDirectional Network-on-Chip based central blocs (UDNs). We also introduce a congestion-aware routing to forward packets adaptively. We compare the current switch architecture to the state-of-the art previous multistage switches under different traffic types. Simulations of various switch settings have shown that the proposed architecture maintains high throughput and low latency performance. |
