“…1, the ToR (Top-of-Rack) and content switches are electronic routers or OpenFlow [20] switches, whereas the aggregation and core switches are optical crossbar or packet switching fabrics. An aggregation switch is always collocated with a set of server racks at the same node and is responsible for data switching among them, and the traffic in the same rack is switched by the ToR switch.…”

Cloud services are fundamentally supported by Data Center Networks (DCNs). With the fast growth of cloud services, the scale of DCNs increases rapidly, leading to a big concern on system scalability due to multiple constraints. Based on optical switching and transmission, this paper proposes a scalable DCN architecture with distributed placement of optical switches and server racks at different nodes in a given optical network. This solves the scalability issue by relaxing power and cooling constraints, and reducing the number of (electronic) switches using high-capacity optical switches, as well as simplifying internal connections of the DCN using wavelengths in the optical network. Moreover, the distributed optical switches provide service access interfaces to demands in vicinities, and thus reduce the transmission cost of the external traffic. The major concern is the additional delay and cost for remote transmissions of the DCN internal traffic. To this end, we study the component placement problem in DCNs under a given set of external demands and internal traffic patterns. By leveraging among multiple conflicting factors such as scalability and internal overhead of the DCN as well as the transmission cost of external traffic, we propose an ILP (Integer Linear Program) to minimize the overall cost of a DCN while satisfying all service demands in the network. This addresses both scalability and cost minimization issues from a network point of view.

“…One early collaboration demonstrated a converged OpenFlow-enabled packet optical network, where circuit flow properties (guaranteed bandwidth, low latency, low jitter, bandwidth-on-demand, fast recovery) provided differential treatment to dynamically aggregated packet flows for voice, video, and web traffic [17,18]. Since then several demonstrations have repeatedly shown the benefits of such ideas [19,20].…”

Control plane techniques are very important for optical networks since they can enable dynamic lightpath provisioning and restoration, improve the network intelligence, and greatly reduce the processing latency and operational expenditure. In recent years, there have been great progresses in this area, ranged from the traditional generalized multi-protocol label switching (GMPLS) to a path computation element (PCE)/GMPLS-based architecture. The latest studies have focused on an OpenFlow-based control plane for optical networks, which is also known as software-defined networking. In this paper, we review our recent research activities related to the GMPLS-based, PCE/GMPLS-based, and OpenFlow-based control planes for a translucent wavelength switched optical network (WSON). We present enabling techniques for each control plane, and we summarize their advantages and disadvantages.
