In LOBS-HC (Labeled Optical Burst Switching with Home Circuits) networks, a critical problem is how to optimally group multiple HCs (Home Circuits) from the same source. We investigate this problem in LOBS-HC rings, and formulate it using ILP (Integer Linear Programming). Since the HC grouping problem is NP-Complete, we propose efficient heuristic algorithms for this problem and evaluate their performance...
We investigate the open problem of optimal home circuit (HC) grouping in LOBS-HC rings, and formulate it using Integer Linear Programming (ILP). Numerical results show that our ILP solutions require minimum wavelengths.
In this paper, we compare performances of a new optical switching paradigm called LOBS-HC and IP/WDM networks. Simulation results show that LOBS-HC is promising in reducing the amount of router processing resources in a network.
Contrary to Optical Circuit Switching (OCS), Optical Burst Switching (OBS) is efficient for bursty traffic but also weak in guaranteeing the delivery of real-time traffic. We have proposed an OBS enhancement approach, called Labeled OBS with Home Circuits or LOBS-HC, which provides each source-destination pair with a wavelength sharable home circuit for the real-time traffic, so it can guarantee lossless...
