Performance analysis of torus optical interconnect with data center traffic

Abstract

Two‐dimensional torus network nodes are typically interconnected using XY routing algorithm for transmitting a packet from a source node to a destination node. In XY routing, if all the paths are used efficiently, the throughput and latency can be improved. In this paper, to utilize all the paths efficiently, we propose a novel binary optical routing algorithm (BORA) to improve the throughput and latency. The throughput is calculated according to the injection rate and number of packets received at the destination. The XY routing algorithm and proposed BORA are implemented using objective modular network testbed in C++ simulation software and the results are analyzed and compared. In this paper, the simulation results show that the network latency reduces to 50% while using the proposed algorithm; moreover, the throughput is also improved.

“…However, the result shown for SAD is often scaled to a vector unit, as viewed in (7), which is also branded as Mean Absolute Error (MAE).…”

“…This feature permits the classification of 2D-tori according to the relative position of the axis with respect to the circle, such that if it is exterior, then a ring torus is obtained, or if it is tangent, then a horn torus is attained, or if it is interior, then a spindle torus is achieved, or if it passes through the center of the circle, then a sphere is done, which is homeomorphic to S 2 and it has no genus [7]. Centering on a ring torus, the minor radius is called section radius, which stands for that of the circle being revolved along the axis, whereas the major radius is named revolution radius, which indicates the shortest segment going from the axis to the center of the circle [8].…”
