<span>Multiprotocol Label Switching (MPLS) is a promising packet switching technology in the field of communication network, allowing router to forward the packets based on labels. However, off-the-shelves routers are made to be non-configurable, making it less suitable for academic research purposes. The aim of this paper is to explore the possibility of developing a configurable MPLS router by reviewing embedded system-based router, software-based router and commercial MPLS router itself. The architecture of the routers will be described in detail and their performances will be compared. From the analysis, we found that the development of reconfigurable MPLS router testbed is achievable by using embedded system-based hardware due to its freedom of reconfigurability.</span>

“…The third VM implements a software version of an optical cross connect, emulating the optical circuit switching hardware that a real node would include. The circuit switch emulator is based on an existing test-bed developed with the Click software router framework [23,24], which has been added the capability to support remote configurations from the SDN controller. Here, incoming packets are directly transferred from the input interface to the output interface after a (software emulated) optical path has been established by the controller.…”

Circuit and packet switching convergence offers significant advantages in core networks to exploit their complementary characteristics in terms of flexibility, scalability and quality of service. This paper considers the possibility of unifying the two different types of transport using the Software Defined Networking (SDN) approach. The proposed architecture applies a modular design to the whole set of node functions, representing the key enabler for a fully programmable network implementation. This paper also proposes a possible extension to the basic concept of flow defined by the current OpenFlow standard to properly support a hybrid network. A set of experiments are performed to assess the main functionality and the performance of the hybrid node where packet and circuit switching are assumed to be configured through the OpenFlow protocol in a fully automated way.

“…This structure implies close traffic monitoring for an effective use of the bandwidth, and transport of the information that stays in the optical domain as much as possible. That solution is to be built upon large and fast optical cross connect switches that can be reconfigured according to the instantaneous bandwidth demand [1][2][3].…”

We present a 32 × 32 port optical cross connect that uses diffraction from a Texas Instruments Digital Micromirror Device (DMD) as the switching element. This system is capable of switching from any input to any output single mode optical fiber with a reconfiguration time of 12 µs. Once set, the latency of the system is only due to the free-space travel of light through the optics, and is about 2 ns. The switch is polarization, data rate, and protocol agnostic, so it will retain its relevance regardless of advances in optical signal formatting. The power consumption of the switch is also independent of the data rate. In addition, considering that all the elements are available off the shelf, the switch is cost-effective.
