A detailed understanding of the many facets of the Internet’s topological structure is critical for evaluating the performance of networking protocols, for assessing the effectiveness of proposed techniques to protect the network from nefarious intrusions and attacks, or for developing improved designs for resource provisioning. In this way Available bandwidth estimation is a vital component of...

A novel design of molecular buffer for molecule storage and delivery using a PANDA ring resonator is proposed. The optical vortices can be generated and controlled to form the trapping tools in the same way as the optical tweezers. In theory, the trapping force is formed by the combination between the gradient field and scattering photons, which is reviewed. By using the intense optical vortice...

In the past years, electronic routers have had trouble keeping up with the increase in optical fiber capacity. As their power consumption has grown exponentially and already exceeds standards, it seems that an alternative solution is mandatory. Many have suggested all-optical routers as an alternative. However, these are deemed too complex, especially given the need to implement both switching ...

In this section, we introduce some techniques for implementing the beam routing, and collision avoidance in the recievers. Each node has a beam router, such as a computer generated hologram or a deformable mirror, which is capable of redirecting k (or 1 in the single-port model) optical beams concurrently. The reconfiguration (programming the computer generated hologram, or deforming the mirror...

A new all-optical networking function is demonstrated using a bank of novel thermallytuned FBG-based optical correlators to construct an “optical bypass” to vastly accelerate conventional electronic internet routers. Based on a simple set of rules, a software algorithm configures the correlators as a routing table cache that can quickly determine the destination port for a large percentage of t...

A new optical device for wavelength auto-router was proposed. Such a structure is useful in the integratedoptic for optical operation and data communication. We use the finite-difference beam propagation method to investigate the phenomenon of the proposed numerical model.

We propose a scalable all-optical switching architecture towards contention-free data center networking. The arrayed-waveguide-grating router (AWGR) based switching fabric utilizes wavelength parallelism to alleviate contention, to reduce latency, and to improve scalability. ©2010 Optical Society of America OCIS codes: (060.4250) Networks; (200.6715) Switching

In this paper we propose a simple model that analyzes the cost saving achieved by Optical IP Switching (OIS), a novel optical architecture, compared to a conventional IP-over-WDM network, where the IP router connects directly to the WDM module. The analysis we propose shows that OIS can bring substantial cost savings in the initial investment of network operators.

The function of a router is to switch arriving packets to their correct output destination. A router is built to achieve a specified capacity (the sum of the rates of its interfaces), and users expect a router to consistently achieve this capacity. However, no commercial high-speed router can guarantee today that it will achieve its full capacity for all arrival traffic patterns. This is due to...
