HiMA: a hierarchical and modular ATM switch with partially shared output buffer

The authors propose a hierarchical and modular ATM switch. To improve the queueing performance, they adopt the output queueing technique and allow several outputs to partially share the same output buffer space. The performance of the proposed switch is evaluated under uniform and nonuniform traffic patterns. Comparisons with the knockout switch, recursive switch, SCOQ, and Christmas-tree switch show that, in terms of complexity, crosspoint count, scalability and synchronisation, the proposed switch is superior.
