“…Since the BL does not provide any buffering capability, the packets through the BL are carried without delay. In [1], the simulation results showed that routing packets through the BL in the M-B-Quadro switching node provided an effective means of increasing the network performance.…”

“…A full slot carrying a packet for output port O 2 is defined to be in State 2. The major difference between the M-B-Quadro switching node [1] and the original M-Quadro switching node [8][9] is that the former replaces the first (last) 2 x 2 switching element with a 2 x 3 (3 x 2) switching element, in addition to the incorporated BL. Since the BL does not provide any buffering capability, the packets through the BL are carried without delay.…”

“…However, even when the VSC control strategy is applied, architectural limitations of the switching elements may cause an internal blocking phenomenon in the M-Quadro structure, and thus induce a corresponding increase in the packet deflection probability [1]. To overcome this problem, the current authors proposed a switch node architecture incorporating an additional bypass transmission line (BL) within the switching node [1].…”

This paper proposes a new switching architecture to be used in all optical networks. The proposed switch, denoted as M 2 -B-Quadro, is an extension of the 2 x 2 two-stage Multi-buffer Bypass Quadro (M-B-Quadro) switch introduced by the current authors in [1]. By incorporating bypass lines and employing a novel switch control strategy, denoted as POS, the proposed switching node effectively resolves packet contentions and provides a substantial reduction in the packet deflection probability. We also demonstrate that such architecture can also be applied to design a generic multiple stages switch of a larger number of input/output ports with superior performances.
