TLDR
This paper presents a systematic approach to designing the switch architecture using a combination of these component choices, while meeting specified design criteria.Abstract:
This paper deals with the efficient design of network switch/routers for an optical data center network. Each switch has multiple components such as ingress/egress interfaces, optical and/or electronic buffers, interconnection switching fabric and so on. There are several possible choices available for each of these components. This paper presents a systematic approach to designing the switch architecture using a combination of these component choices, while meeting specified design criteria. It requires formally defining the structure of a switch and enforcing semantics across components. This is formulated as a constraint optimization problem with formal language grammar guiding its search process. This problem formulation is used to identify the best-possible architecture for a hierarchical DCN. Two of the three solutions identified were new and were not reported in literature. These solutions were also validated experimentally.read more

Design and Analysis of Scheduling Algorithms for Optically Groomed Data Center Networks
TL;DR: It is shown that the problem without any precedence constraints is NP-complete and a greedy algorithm is proposed and shown to be optimal and theoretical approximation for the performance of scheduling with the greedy algorithms is presented.

Empirical model for combinatorial data center network switch design.
TL;DR: From the experimental analysis, it was observed that the desired objective can be decided by considering a zeroth-order threshold for optical power at the receiver and before the amplifier, paving way for the theoretical evaluation of several other such designs using this empirically derived model.

A scalable, commodity data center network architecture
TL;DR: This paper shows how to leverage largely commodity Ethernet switches to support the full aggregate bandwidth of clusters consisting of tens of thousands of elements and argues that appropriately architected and interconnected commodity switches may deliver more performance at less cost than available from today's higher-end solutions.
