Optical burst switching (OBS) - a new paradigm for an Optical Internet^{1}
The general concept of OBS protocols and in particular, those based on Just-Enough-Time (JET), is described, along with the applicability ofOBS protocols to IP over WDM, and the performance of JET-based OBS Protocols is evaluated.
Integrated cellular and ad hoc relaying systems: iCAR
The results show that with a limited number of ARSs and some increase in the signaling overhead (as well as hardware complexity), the call blocking/dropping probability in a congested cell and the overall system can be reduced.
QoS performance of optical burst switching in IP-over-WDM networks
It is shown that with limited FDLs, the offset-time-based QoS scheme can be very efficient in supporting basic QoS, and suitable for the next generation optical Internet.
Medium access control with a dynamic duty cycle for sensor networks
A sensor medium access control protocol with dynamic duty cycle, DSMAC, which achieves a good tradeoff between the two performance metrics without incurring much overhead.
Optical burst switching: a new area in optical networking research
This tutorial gives an introduction to optical burst switching and compare it with other existing optical switching paradigms, and describes a prevailing protocol for OBS networks called just-enough-time (JET).

The OBS paradigm is described, and the use of labeled OBS, or LOBS, is proposed as a natural control and provisioning solution under the ubiquitous IP multiprotocol label switching framework.
Constrained multicast routing in WDM networks with sparse light splitting
This paper studies constrained multicast routing in WDM networks with sparse light splitting, i.e., where some switches are incapable of splitting light due to evolutional and/or economical reasons.
An effective and comprehensive approach for traffic grooming and wavelength assignment in SONET/WDM rings
This study shows that using the proposed algorithms, lower bounds on the number of wavelengths and S-ADMs required for a given traffic pattern can be closely approached in most cases or even achieved in some cases.
Optical burst switching for service differentiation in the next-generation optical Internet
This article describes how OBS can be applied to the next-generation optical Internet, and in particular how offset times and delayed reservation can help avoid the use of buffer, and support quality of service at the WDM layer.
Cost Efficient Design of Survivable Virtual Infrastructure to Recover from Facility Node Failures
This paper develops two solutions namely the 1-redundant scheme and the K-redundy scheme for surviving facility node failures while minimizing network resource costs and proposes efficient heuristics based on the MILP formulations.
